Red Light Therapy in Menopause and Perimenopause
· PrimeTrust Lda
What really happens during perimenopause and menopause?
The perimenopause is the transitional period that begins when changes related to the menstrual cycle appear and ends one year after the last period. Menopause itself is considered after 12 consecutive months without menstruation, in the absence of another physiological or clinical cause.
The World Health Organization states that natural menopause usually occurs between the ages of 45 and 55, and is associated with the progressive loss of ovarian follicular function and the decrease in circulating estrogen levels.
It is precisely this hormonal change that explains why seemingly unrelated symptoms can appear at the same time.
Among the most common are:
- hot flashes and night sweats;
- sleep changes and insomnia;
- mood swings, anxiety, or depressive symptoms;
- vaginal dryness and discomfort during sexual intercourse;
- urinary changes;
- loss of muscle mass and strength;
- changes in body composition;
- increased skin vulnerability;
- progressive reduction in bone mineral density;
- metabolic and cardiovascular changes.
The WHO particularly draws attention to the loss of bone density, changes in body composition, and increased cardiovascular risk after menopause.
The interesting question for photobiomodulation begins here: many of these tissues depend heavily on mitochondrial efficiency, blood perfusion, inflammatory regulation, and repair capacity.
What is Red Light Therapy or Photobiomodulation?
Photobiomodulation, or PBM (photobiomodulation), uses certain wavelengths of red and near-infrared light to induce biological responses in tissues without resorting to ultraviolet radiation, intense heat, or invasive procedures.
The scientific literature often places photobiomodulation in the range of approximately 600 to 1,100 nm, although the parameters used vary considerably from study to study.
The principle is not simply “heating the body with light.”
Photons reach the tissues and can be absorbed by light-sensitive cellular molecules. Among the most studied mechanisms is the interaction with cytochrome c oxidase, an enzyme in complex IV of the mitochondrial respiratory chain.
The predominant hypothesis proposes that light may modify the activity of this respiratory chain and the signaling associated with:
- ATP;
- nitric oxide;
- reactive oxygen species at physiological concentrations;
- intracellular calcium;
- transcription pathways related to inflammation, repair, and cellular adaptation.
However, it is important not to oversimplify the mechanism. The scientific literature itself highlights that cytochrome c oxidase does not necessarily explain all observed effects, and other photoreceptors and mechanisms continue to be investigated.
It is more accurate to say that PBM modulates bioenergetics and cellular signaling than to simply state that it “increases ATP.”
And what does this have to do with menopause?
A lot—but with an important caveat:
there is currently no robust clinical evidence that a red light panel directly increases estrogen levels in menopausal women.
This distinction is essential.
We should not confuse the possibility of acting on cellular processes affected by estrogen loss with the ability to replace that hormone.
Photobiomodulation may potentially work downstream of the hormonal change.
That is:
less estrogen → changes in various tissues → changes in mitochondrial, vascular, muscular, skin, and inflammatory function → some of these processes may be modulated by PBM.
This is very different from saying:
red light → increased estrogen → end of symptoms.
The second statement is not currently demonstrated in menopausal women.
The less obvious connection: menopause, mitochondria, and the feeling of “energy”
It is common to hear menopausal women say:
“I’m not really sick. I just don’t have the same energy anymore.”
This phenomenon is multifactorial.
Fragmented sleep, hormonal changes, stress, metabolic changes, loss of muscle mass, and reduced physical activity can all contribute simultaneously.
But there is another relevant angle: mitochondrial efficiency tends to change with aging.
Mitochondria are cellular structures responsible for much of the energy production used by tissues.
This is precisely why PBM research focuses so much on them.
Mechanistic reviews describe changes in the mitochondrial respiratory chain, redox signaling, nitric oxide, and cellular adaptation mechanisms after adequate exposure to red or NIR light.
This does not mean that a 10-minute session immediately transforms a tired woman into an athlete.
It means something potentially more interesting in the long term: PBM can be seen as a cellular stimulus, not a stimulant.
It does not act like caffeine.
The intention is to modulate the tissues’ ability to respond, recover, and adapt.
1. Muscle mass, strength, and recovery: an underestimated priority after 40
One of the biggest mistakes in approaching menopause is focusing all attention on body weight.
Maintaining muscle mass may be much more important than the number on the scale.
With aging and hormonal changes, the risk of gradual loss of muscle mass, strength, and power increases.
This affects:
- future autonomy;
- insulin sensitivity;
- metabolism;
- bone health;
- balance;
- fall risk;
- ability to train;
- recovery.
Photobiomodulation has been studied in the context of muscle performance and recovery, often applied before or after exercise.
There is even research specifically conducted in postmenopausal women.
In a randomized trial published in Lasers in Medical Science, 34 postmenopausal women performed eight weeks of resistance training. One group additionally received PBM with 630 and 850 nm over the quadriceps. Both groups improved strength, but photobiomodulation did not produce a significant additional benefit over training.
This is an extremely useful result.
Why?
Because it shows precisely how we should interpret PBM.
Light does not replace the stimulus the body needs.
If the goal is to preserve muscle during menopause, strength training, adequate protein intake, recovery, and sleep remain essential.
Photobiomodulation can be studied as a complementary recovery tool, but it should not be presented as a substitute for exercise.
A body panel becomes particularly interesting because of its ability to irradiate large muscle groups simultaneously—back, legs, glutes, shoulders—something that is difficult to do with small devices.
2. Muscle and joint pain: when “aging” begins to show up in movement
Morning stiffness, joint discomfort, and slower recovery are frequent complaints at this stage of life.
PBM has a long history of research into musculoskeletal pain and inflammatory processes.
Among the proposed biological effects are the modulation of:
- NF-κB;
- inflammatory cytokines;
- oxidative stress;
- microcirculation;
- tissue repair mechanisms.
A widely cited review on the anti-inflammatory effects of photobiomodulation describes precisely this interaction between photons, mitochondria, physiological ROS, nitric oxide, and cellular transcription pathways.
For a physically active woman, this opens up a particularly interesting use:
not using red light to avoid exertion, but to be able to continue moving, training, and recovering.
That conceptual difference is huge.
3. Cardiovascular health: a particularly interesting—but still experimental—field
Before menopause, estrogen exerts several cardiovascular effects.
With its reduction, factors such as lipid profile, endothelial function, and cardiovascular risk progressively change. The Menopause Society highlights that much of cardiovascular disease in women appears in the years after menopause.
Nitric oxide is particularly interesting in this context because it participates in the ability of blood vessels to dilate.
And NO is also one of the most studied molecules in PBM.
In 2025, researchers studied 660 nm photobiomodulation in an animal model of menopause induced by ovariectomy. The treated animals showed:
- lower mean blood pressure;
- improved endothelium-dependent vasodilation;
- increased serum nitric oxide.
But there is an important limitation: they were rats, not women.
The study is biologically interesting, but it still does not allow us to state that using a red light panel at home reduces cardiovascular risk during menopause.
4. Skin: perhaps one of the areas where home use makes the most sense
Less estrogen also means changes in:
- collagen synthesis;
- skin thickness and elasticity;
- hydration;
- repair capacity;
- firmness.
Unlike some other menopausal applications, skin photobiomodulation already has relevant human clinical research.
A 2025 clinical trial evaluated 95 women between the ages of 45 and 60 using red LED at 660 nm for facial rejuvenation. Frequencies of two and three applications per week over four weeks were compared.
Although the study was not specifically designed to “treat menopause,” the population analyzed directly coincides with the age at which many women go through perimenopause and menopause.
Research in this area suggests a potential influence on fibroblasts, collagen, microcirculation, and repair processes.
It is perhaps the perfect example of how to think about PBM at this stage:
not treating menopause—treating or supporting a tissue that is undergoing changes during menopause.
5. Sleep, mood, and brain: probably the area that deserves the most caution
Night sweats and hot flashes can deeply fragment sleep.
But even women without intense vasomotor symptoms can develop difficulties in:
- falling asleep;
- staying asleep;
- waking up rested;
- concentrating during the day.
Transcranial PBM is currently being investigated in areas such as sleep, depression, and brain function.
A randomized, double-blind, placebo-controlled trial published in 2025 evaluated transcranial photobiomodulation administered at home in people with major depression, also monitoring sleep quality.
But two things should be underlined:
- it was not a study on menopause;
- it used a specific transcranial device, not a conventional body panel.
Therefore, stating that a full-body panel “cures menopause insomnia” would go far beyond the available evidence.
Still, the brain–energy–sleep–mood axis has become an extremely interesting area of photobiomodulation research.
6. Intimate health and menopausal genitourinary syndrome
Menopausal genitourinary syndrome may include:
- vaginal dryness;
- burning;
- tissue changes;
- pain during sexual intercourse;
- urinary symptoms;
- incontinence.
It is an important consequence of estrogen reduction and, according to the WHO, often remains underdiagnosed and undertreated.
Recent PBM research has made this one of the most interesting fields in women’s health.
A recently published randomized, double-blind, placebo-controlled clinical trial studied 65 postmenopausal women with genitourinary symptoms.
Four weekly sessions of 808 nm PBM laser were performed, applied locally.
The treated group showed a reduction in urinary leakage and reported improvement in vaginal dryness and burning; no significant difference in sexual function was observed. The authors themselves consider additional studies necessary to confirm the effects and determine protocols.
Another prospective study published in 2026 evaluated sessions of 660 nm through a specific vaginal probe in postmenopausal women with genitourinary syndrome.
There is also recent research in women with breast cancer and sexual dysfunction associated with hormone therapy, where specific local PBM protocols were associated with a reduction in vaginal pain and improvement in sexual function.
But pay attention to the fundamental difference:
these studies did not use external red light panels.
They used equipment specifically designed for vaginal or localized application.
It is not scientifically correct to assume that exposing the abdomen or pelvic region to a panel automatically produces the same results.
7. Can red light affect hormone levels?
This is probably the most important question in the article.
The short answer is:
it can potentially influence hormone-dependent tissues and mechanisms associated with ovarian function, but there is currently not enough clinical evidence to state that a home panel increases estrogen or reverses menopause.
There is fascinating preclinical data.
A aceleração da perda de massa óssea após a menopausa está bem estabelecida.
O estrogénio participa na regulação do metabolismo ósseo e a sua diminuição favorece alterações do equilíbrio entre formação e reabsorção óssea.
Embora existam estudos experimentais sobre PBM e regeneração óssea, não existe evidência suficiente para recomendar painéis de luz vermelha como tratamento ou prevenção da osteoporose pós-menopáusica.
Para a saúde óssea continuam a ser prioritários:
- treino de resistência;
- atividade com carga;
- ingestão adequada de proteína;
- cálcio e vitamina D quando indicados;
- avaliação clínica de risco;
- densitometria nas mulheres para quem está recomendada;
- medicação específica quando necessária.
A PBM poderá eventualmente desempenhar um papel complementar, mas não deve desviar a atenção das intervenções com benefício já demonstrado.
O verdadeiro interesse de um painel: não é uma sessão isolada, é a capacidade de criar rotina
Aqui surge um fator pouco discutido na investigação clínica: aderência.
Uma tecnologia só é útil se conseguir fazer parte da vida real.
Para muitas mulheres entre os 40 e os 60 anos, a dificuldade não é encontrar mais uma clínica onde fazer um tratamento.
É encontrar tempo.
Trabalho, filhos, pais, responsabilidades domésticas e uma lista interminável de obrigações fazem com que o próprio autocuidado seja continuamente adiado.
Um painel de luz vermelha instalado em casa reduz essa fricção.
Permite integrar sessões em momentos como:
- depois do treino;
- ao final do dia;
- enquanto se ouve música ou um podcast;
- durante uma rotina de recuperação;
- associado a mobilidade, respiração ou relaxamento.
Essa conveniência pode ser tão relevante quanto a tecnologia.
Como utilizar um painel de luz vermelha na menopausa?
Não existe um protocolo universal de “luz vermelha para menopausa”.
Aliás, esse protocolo provavelmente nunca deveria existir, porque menopausa não é uma única condição.
Uma mulher pode estar principalmente preocupada com recuperação muscular.
Outra com pele.
Outra com dor.
Outra com sono.
A utilização deverá depender de:
- objetivo;
- comprimentos de onda do equipamento;
- irradiância;
- distância;
- tempo de sessão;
- área exposta;
- frequência.
E existe ainda um princípio fundamental da PBM: mais luz não significa necessariamente melhor resultado.
A literatura descreve frequentemente uma resposta bifásica à dose: doses insuficientes podem não produzir efeito significativo, enquanto exposições excessivas podem reduzir ou inverter determinados efeitos biológicos.
Por isso, potência sem dosimetria não é sinónimo de qualidade.
Contraindicações e precauções
A fotobiomodulação é, de forma geral, considerada uma modalidade com um perfil de segurança favorável. Um consenso internacional publicado em 2025 concluiu que a PBM apresenta um bom perfil de segurança em adultos e que a luz vermelha utilizada em PBM não demonstrou induzir dano no ADN nas condições analisadas.
Ainda assim, existem situações que justificam prudência.
Deve procurar aconselhamento clínico antes da utilização quando existir:
- doença oncológica ativa ou recente, sobretudo antes de irradiar diretamente uma região tumoral;
- utilização de medicamentos ou patologias que provoquem fotossensibilidade;
- doença ocular relevante;
- condição dermatológica ainda não diagnosticada;
- sintomas ginecológicos novos, hemorragia anormal ou dor inexplicada.
Também se deve evitar olhar diretamente para LEDs de elevada intensidade e seguir sempre as recomendações de proteção ocular do fabricante.
E há uma regra particularmente importante na menopausa:
um novo sintoma não deve ser automaticamente atribuído à menopausa.
Hemorragia vaginal pós-menopausa, dor persistente, perda inexplicada de peso, alterações mamárias ou sintomas cardiovasculares merecem avaliação médica.
O que a ciência permite concluir neste momento?
A fotobiomodulação é biologicamente plausível e clinicamente interessante para várias áreas relevantes durante a menopausa.
Existe evidência humana crescente em:
pele e envelhecimento cutâneo;
dor e processos musculoesqueléticos;
recuperação;
algumas aplicações geniturinárias específicas.
Existem também áreas promissoras, mas ainda insuficientemente estudadas diretamente em mulheres menopáusicas:
função vascular;
sono;
função cerebral;
metabolismo;
saúde ovárica;
saúde óssea.
E existem afirmações que atualmente não são suportadas por evidência clínica suficiente:
“A luz vermelha aumenta o estrogénio.”
“A luz vermelha reverte a menopausa.”
“A luz vermelha trata osteoporose.”
“A luz vermelha elimina afrontamentos.”
Esta distinção não diminui a tecnologia.
Pelo contrário.
É precisamente aquilo que separa fotobiomodulação baseada em evidência de marketing excessivo.

Fotobiomodulação em casa: onde entra a TheraFactor®?
Para quem decide integrar a fotobiomodulação na rotina, existe uma diferença importante entre ter uma fonte de luz vermelha e utilizar um equipamento desenvolvido especificamente para PBM.
A linha TheraPRO da TheraFactor® foi concebida para permitir utilização corporal localizada ou em áreas progressivamente maiores, dependendo do modelo escolhido.
Os equipamentos combinam diferentes comprimentos de onda de luz vermelha e infravermelho próximo e permitem adaptar a exposição ao objetivo e à área corporal, tornando possível construir uma solução desde utilização pessoal localizada até configurações corporais mais abrangentes.
Isto torna a utilização particularmente interessante numa fase da vida em que a prioridade não deveria ser procurar uma única “solução milagrosa”, mas construir um ecossistema sustentável de:
força + movimento + sono + alimentação + recuperação + acompanhamento médico + tecnologias complementares.
A fotobiomodulação pode ser uma dessas tecnologias.
Não precisa de substituir nenhuma das restantes para acrescentar valor.
ATENÇÃO:
Painéis de luzes comuns não têm a potência, nem o comprimento de onda certo para ativar mitocôndrias. Os Paineis TheraPRO da TheraFactor® usam diodos duplos de alta precisão, protegidos contra EMF e com emissão exata nas faixas terapêuticas.
Nota: as características acima correspondem à informação técnica disponibilizada pela TheraFactor®. A eficácia de qualquer protocolo depende, entre outros fatores, da dose, distância, duração, área tratada e objetivo de utilização.
A menopausa não deve ser o momento em que começa a aceitar menos do seu corpo
Talvez a maior mudança de perspetiva seja esta:
A menopausa não é apenas uma lista de sintomas para tolerar.
É também um momento em que preservar músculo, capacidade metabólica, qualidade da pele, movimento, recuperação e autonomia futura ganha ainda mais importância.
A fotobiomodulação não elimina a necessidade de treinar.
Não substitui uma consulta médica.
Não substitui terapêutica hormonal quando esta é indicada.
E não transforma uma má rotina numa boa rotina.
Mas pode tornar-se uma ferramenta particularmente fácil de integrar numa estratégia mais abrangente de saúde e longevidade.
Se há meses que pensa em começar a cuidar melhor da recuperação e continua a adiar porque “ainda não está assim tão mal”, talvez valha a pena questionar essa lógica.
Porque esperar até sentir que perdeu energia, força ou qualidade de vida suficiente para finalmente agir raramente é a melhor estratégia.
Conheça a linha TheraPRO da TheraFactor® e descubra como integrar a Terapia de Luz Vermelha e Infravermelho Próximo na sua rotina.
Não porque todas as mulheres precisem de fotobiomodulação.
Mas porque, para quem decide investir conscientemente na próxima fase da sua saúde, pertencer ao grupo que começa antes de precisar costuma ser uma escolha mais fácil do que tentar recuperar mais tarde aquilo que foi sendo adiado.
Red Light Therapy in Menopause and Perimenopause: Cellular Energy, Recovery, Skin, Sleep and Women's Well-Being
Meta description: Discover how red light and near-infrared therapy can support women's health in perimenopause and menopause, from cellular energy and muscle recovery to skin, circulation, sleep and well-being.
There is a phase of life when many women begin to notice a different body: workouts seem to require more recovery, sleep is no longer as restorative, body composition changes, skin loses firmness, and energy no longer responds the same way.
It is tempting to simply attribute it all to “age.” But perimenopause and menopause are much more than the end of the menstrual cycle. The progressive change in the hormonal environment affects very different tissues such as muscle, skin, brain, blood vessels, bones, and the genitourinary system.
It is precisely in this context that Red Light and Near-Infrared Therapy — or Photobiomodulation (PBM) has been attracting growing interest.
The reason is particularly interesting: instead of acting only on an isolated symptom, photobiomodulation interacts with some of the cellular mechanisms that support energy production, recovery, circulation, and tissue adaptation.
For many women, this turns a red light panel into a simple tool to integrate into a routine of longevity, recovery, and at-home self-care.
What changes in the body during perimenopause and menopause?
Perimenopause is the transitional period leading up to menopause and can begin several years before the final period. Menopause is considered established after 12 consecutive months without menstruation.
The decrease and fluctuation of estrogen may be associated with:
- hot flashes and night sweats;
- sleep changes;
- fatigue;
- mood swings;
- reduced recovery capacity;
- changes in body composition;
- gradual loss of muscle mass;
- reduced bone density;
- skin dryness and aging;
- cardiovascular changes;
- genitourinary discomfort.
The World Health Organization highlights that the hormonal changes during this phase can have relevant effects on body composition, bone health, cardiovascular health, and quality of life.
The important point is that these systems do not work in isolation.
They depend on cellular metabolism, blood circulation, inflammatory signaling, and the ability of tissues to adapt and regenerate.
And that is where photobiomodulation becomes particularly interesting.
What is Red Light Therapy?
Photobiomodulation uses specific wavelengths of red light and near-infrared to stimulate biological responses in tissues.
We are not talking about ultraviolet light or a simple heat source.
Photons can penetrate tissues and interact with light-sensitive cellular structures, including components involved in mitochondrial activity.
Mitochondria are often described as the “powerhouses” of cells because they participate in the production of ATP, the molecule used as an energy source in most cellular processes.
Research on PBM associates proper exposure to red light and NIR with changes in:
- mitochondrial activity;
- nitric oxide availability;
- redox signaling;
- local circulation;
- inflammatory response;
- cellular repair;
- expression of genes related to adaptation and regeneration.
An international consensus published in the Journal of the American Academy of Dermatology in 2025 considered PBM a safe modality in adults and recognized established clinical applications in various areas.
Menopause, hormones, and mitochondria: a connection worth paying attention to
When talking about menopause, estrogen immediately comes to mind.
But the hormonal impact does not end with the concentration of the hormone in the blood.
Estrogen also influences:
- mitochondrial function;
- metabolism;
- muscle;
- collagen production;
- blood vessels;
- brain;
- reproductive system.
Therefore, one of the most interesting ways to look at photobiomodulation is not to imagine light as a “hormone,” but as a technology capable of acting on some of the cellular systems that undergo changes when the hormonal environment changes.
There are experimental studies on ovarian aging in which PBM was associated with improved mitochondrial function, lower oxidative stress, and lower inflammatory signaling.
Research in this area is still evolving, but it reinforces a relevant idea: hormones and cellular metabolism are deeply interconnected.
Thus, even when the goal is not to directly alter hormone levels, supporting tissue function can be an interesting strategy during this phase of life.
1. Energy and fatigue: when rest no longer seems enough
One of the most frustrating complaints of perimenopause is feeling like energy has simply disappeared.
Sleeping more does not always help.
A coffee helps for a few hours, but it does not change the cellular capacity to produce and use energy.
This is where the PBM approach is different.
By interacting with mitochondrial processes, photobiomodulation seeks to promote the metabolic efficiency of cells.
This does not mean a stimulating effect similar to caffeine.
On the contrary, it is a stimulus directed at cellular bioenergetics.
For a woman who is starting to think about longevity, the question then stops being just:
“How can I feel less tired?”
and becomes:
“How can I keep my tissues metabolically active for longer?”
2. Muscle recovery and strength maintenance
Muscle preservation becomes increasingly important from perimenopause onward.
Muscle is not just for having strength or a certain physical appearance.
It is directly related to:
- glucose metabolism;
- mobility;
- autonomy;
- bone health;
- balance;
- healthy aging.
PBM has been widely studied in the context of muscle function, exercise, and recovery.
There is even research conducted specifically in postmenopausal women.
In a randomized trial with 34 postmenopausal women, wavelengths of 630 nm and 850 nm were used together with resistance training for eight weeks. The study confirmed significant improvements with training, although in that specific protocol, PBM did not produce a significant additional increase in strength.
This result is interesting because it shows that PBM can fit particularly well into a strategy of recovery and exercise support, rather than replacing the need for movement.
A body panel offers an important practical advantage here: it can allow the simultaneous exposure of large muscle groups such as legs, back, glutes, and shoulders.
For women who work out regularly, this makes the post-workout session extremely easy to integrate.
3. Skin, collagen, and skin aging
This is one of the most studied areas of red light.
With the decrease in estrogen, skin can become progressively:
- thinner;
- drier;
- less firm;
- less elastic.
Collagen production also tends to decrease.
And that is precisely where red light presents particularly interesting clinical data.
A randomized clinical trial published in 2025 studied 95 women between the ages of 45 and 60 using 660 nm red LED light for facial rejuvenation.
Other studies with 660 nm LEDs showed improvements in wrinkles and parameters related to photoaging.
The proposed mechanism mainly involves:
- fibroblasts;
- collagen synthesis;
- microcirculation;
- tissue repair;
- inflammation modulation.
For those looking to age while maintaining healthy skin, photobiomodulation has a particular advantage: it is non-invasive and allows for recurring use.
4. Circulation and vascular health
Cardiovascular health becomes even more important after menopause.
Estrogen is related to vascular regulation mechanisms, and its decrease can contribute to changes in endothelial function and cardiovascular risk.
One of the most studied molecules in photobiomodulation is precisely nitric oxide (NO).
Nitric oxide participates in the relaxation of blood vessels and the regulation of circulation.
PBM can influence the local availability of NO and microcirculation, making the interaction between red light and vascular function particularly interesting during this phase of life.
Although some of the research directly related to menopause still results from experimental models, the results justify the growing interest in this area.
5. Inflammation, muscle discomfort, and stiffness
The feeling of recovering more slowly, waking up stiff, or starting to feel minor pains that did not exist before is extremely common.
PBM has been studied for decades for its ability to modulate inflammatory processes.
Light can trigger cellular signaling associated with:
- cytokines;
- oxidative stress;
- microcirculation;
- repair mechanisms;
- local inflammatory response.
This helps explain why photobiomodulation has found applications in areas as different as muscle recovery, injuries, pain, and tissue regeneration.
For many women, a red light session at the end of a workout or the day can also become a recovery ritual — an interesting combination of physiological benefit and a moment dedicated to one's own body.
6. Intimate health and menopausal genitourinary syndrome
The reduction of estrogen can cause changes in vaginal and urinary tissues, leading to:
- dryness;
- discomfort;
- burning;
- pain during sexual intercourse;
- urinary symptoms;
- incontinence.
This is one of the areas in which recent PBM research has become especially interesting.
A randomized, double-blind clinical trial published in 2026 evaluated 65 postmenopausal women subjected to 808 nm PBM. The group that received the treatment showed a reduction in urinary leakage and reported improvements in vaginal dryness and burning.
Another prospective study used 660 nm PBM for eight sessions in women with menopausal genitourinary syndrome.
And recent research also evaluated the combination of PBM with pelvic floor training, finding improvements in different functional and quality-of-life indicators.
These protocols use devices specific to the region and should not be automatically equated to the use of a body panel, but they demonstrate how female tissues respond to photobiomodulation.
7. Sleep, brain, and emotional balance
Perimenopause can turn a peaceful night into a series of awakenings.
Night sweats, hormonal changes, and accumulated stress end up influencing also:
- concentration;
- memory;
- mood;
- motivation;
- recovery capacity.
Research on brain photobiomodulation is growing rapidly, notably in areas related to brain metabolism, mood, and sleep.
Although many of these protocols use specific equipment, there is an idea particularly relevant for those who use body PBM:
sleep, exercise, recovery, and metabolism are interconnected.
Improving the recovery routine can have repercussions that go far beyond the muscle.
8. A panel at home changes one essential thing: consistency
A technology can be extraordinary in the lab and little useful in real life if it is complicated to use.
This is where home panels offer a huge advantage.
There is no need to book an appointment, travel to a clinic, or reorganize half the day.
A session can be integrated:
- after a workout;
- before a shower;
- while listening to a podcast;
- at the end of the day;
- during a mobility routine;
- together with recovery practices.
And consistency is particularly relevant in photobiomodulation.
Just as with exercise, diet, or sleep, the benefit is not in doing an exceptional session once a month, but in managing to turn a healthy behavior into a routine.
How to choose a red light panel?
Not all equipment that emits red light is equivalent photobiomodulation equipment.
It is important to evaluate:
Wavelengths
Research uses specific wavelengths because different ranges have different absorption and penetration characteristics.
Red light acts mainly on more superficial tissues, while near-infrared can reach greater depth.
Irradiance
It is the amount of luminous power that reaches a given area.
A very weak panel may require excessive exposure times.
Dose
The dose results from the combination of irradiance and time.
In PBM, more does not automatically mean better.
The goal is to use an adequate dose.
Treatment area
A larger panel allows for simultaneously reaching large body regions, making its use particularly interesting for recovery, exercise, and full-body protocols.
Are there contraindications?
PBM generally has a very favorable safety profile.
The 2025 international consensus mentioned above concluded that photobiomodulation is safe for adults and that the red light used in PBM has not been shown to cause DNA damage.
Nevertheless, it is prudent to seek professional advice in specific situations, namely:
- known photosensitivity;
- use of photosensitizing medications;
- relevant eye conditions;
- active oncological disease;
- as-yet undiagnosed clinical conditions.
You should also avoid looking directly at high-intensity LEDs and follow the equipment's usage recommendations.
What can we learn from current research?
Photobiomodulation has long moved beyond the idea of a simple “wellness light”.
We are looking at a scientific field that investigates the interaction between light and cellular biology and already has clinical studies in numerous applications.
In the context of menopause and perimenopause, some areas appear particularly relevant:
cellular energy and mitochondrial function;
muscle recovery;
skin and collagen;
microcirculation;
inflammatory modulation;
genitourinary health;
longevity and functional maintenance.
At the same time, new lines of research are increasingly exploring the link between PBM, ovarian aging, vascular function, the brain, and metabolism.
For a woman at this stage of life, perhaps the best way to look at red light is not as a response to a single symptom, but as a technology that supports the body's ability to recover, adapt, and age better.

TheraPRO: integrate photobiomodulation into your routine without turning self-care into another obligation
The biggest advantage of having a photobiomodulation panel at home may be precisely this: the technology is available when the body needs it.
The TheraPRO line from TheraFactor® was developed to allow different levels of use, from localized exposure to settings for larger body areas.
The panels use multiple wavelengths of red and near-infrared light, allowing them to work on different depths and body regions simultaneously.
They can be easily integrated into a routine for:
- Recovery;
- exercise and performance;
- skin care;
- well-being;
- biohacking;
- longevity.
For a woman entering perimenopause or menopause, this can represent something very simple but powerful: setting aside a few minutes a day to continue consciously investing in the body she will live in for the next few decades.
ATTENTION:
Common light panels do not have the power or the right wavelength to activate mitochondria. TheraFactor® TheraPRO Panels use high-precision dual diodes, protected against EMF and with exact emission in the therapeutic ranges.
Menopause does not have to be the time when you start accepting less energy, less recovery, or less physical capacity.
It can be precisely the opposite: the time when self-care stops being optional and becomes part of a conscious longevity strategy.
Because it is easy to keep postponing as long as the body still compensates.
It is harder to wish you had started sooner a few years from now.
Discover the TheraPRO line from TheraFactor® and find the Red Light and Near-Infrared Therapy solution that best integrates into your routine.
Your body will accompany you throughout the next phase of your life. It is worth starting to treat it today so it responds the way you want tomorrow.
