What holds up
Engage in a minimum of 250 minutes of physical activity per week, distributed as approximately 150 minutes of moderate cardio and 100 minutes of muscle strengthening (roughly 35 minutes per day), to optimize longevity, fitness, and blood pressure regulation, with benefits that are particularly pronounced in women.
Mary Claire Haver’s recommendation is based on particularly solid and up-to-date science. The 150-minute cardio recommendation aligns with global guidelines from the WHO (Bull et al., 2020), derived from large reviews and observational studies linking this dose to a healthy cardiovascular system. Regarding the 100 minutes of strengthening, the meta-analysis by Shailendra et al. (2022) shows that such a practice actively supports general vitality and cellular longevity. Fascinatingly, the observational study by Ji et al. (2024) confirms that women experience increased longevity gains from an exercise volume often lower than that of men. Furthermore, the positive impact of strength training on managing blood pressure in women is well-supported by the observational study by Park & Park (2024). This comprehensive and accessible approach of 35 minutes per day constitutes an ideal balance for optimizing daily fitness.
The use of low-dose vaginal estrogen for intimate comfort during menopause is associated with a 15 to 20% reduction in the risk of rectal cancer, although this should not be the primary reason for starting this treatment.
The creator draws very accurately on a large Finnish observational study (Siitonen et al., 2025, published in Maturitas) that highlights this encouraging link. She correctly notes the limitations of this type of evidence, which is unable to establish direct causality, particularly due to user bias where individuals consult their doctors more regularly and benefit from better follow-up. Furthermore, the efficacy of this local treatment for restoring intimate tissues and reducing urinary discomfort is already widely validated by scientific consensus, such as that of the Menopause Society. Regarding digestive protection, large historical randomized clinical trials (such as the Women's Health Initiative) had already observed a decrease in colorectal cancers with systemic hormones, which makes this local pathway very plausible but still in need of confirmation by rigorous prospective trials. The message is therefore perfectly balanced, presenting this data as a reassuring bonus rather than an established therapeutic promise.
Treat night sweats and hot flashes that disrupt sleep during perimenopause, as these specific awakenings are associated with a decline in mental vitality decades later, unlike simple light sleep.
The creator relies on a recent observational study published in the journal Menopause (conducted by researchers at Harvard) that followed approximately 2,100 women, which provides a solid level of observational evidence for identifying long-term correlations. This research intriguingly shows that it is not sleep difficulties in general, but specifically awakenings caused by thermal variations (hot flashes), that are linked to lower memory scores years later. These data align with other large observational studies, notably the famous U.S. cohort SWAN (Study of Women's Health Across the Nation), which also links the severity of these nocturnal heat waves to fluctuations in mental clarity. The creator demonstrates exemplary rigor by highlighting herself that this study is observational, based on subjective reports, and does not prove a cause-and-effect relationship. Her message is not alarmist and focuses solely on the importance of seeking comfort solutions to preserve one's future well-being.
Current medical training programs do not sufficiently prepare healthcare professionals for menopause; this instruction must be made mandatory because the decline in estrogen impacts the entire body (heart, bones, brain) long after the end of the reproductive period.
Mary Claire Haver's assessment regarding the lack of preparation for future practitioners is scientifically supported. A questionnaire-based study published in the Mayo Clinic Proceedings (Kling et al., 2019) confirms that only 6.8% of internal medicine and gynecology residents feel fully equipped to manage this life transition. Physiologically, the fact that estrogen acts well beyond fertility is a fact firmly established by fundamental research: estrogen receptors are present in vessel walls, bone tissue, and the brain, influencing energy and cognitive vitality. Furthermore, the North American Menopause Society (NAMS) agrees in its expert opinions on the urgent need to improve clinical training in the face of this growing need. The creator's call to reform curricula is a legitimate public health plea, entirely consistent with current professional survey data.
You should not buy NAD+ supplements in the hope of relieving menopause symptoms (hot flashes, sleep issues), as there is currently no solid scientific evidence (such as a placebo-controlled clinical trial) validating their efficacy.
The creator's position is scientifically very accurate and faithfully describes the current state of research. The rigorous study she mentions, published in the journal Science by Yoshino et al. (2021)—a randomized controlled trial (RCT)—clearly shows that an NAD+ precursor improves muscle insulin sensitivity in postmenopausal, prediabetic women, but it did not measure general well-being, sleep, or hot flashes. Regarding these latter aspects, research is limited to very short pilot studies without a control group, which is more akin to a placebo effect than genuine proof of efficacy. Experts agree that while NAD+ is an exciting avenue for cellular vitality, clinical data are lacking to make it a ritual focused on menopause comfort. The creator's field observation, which qualifies as expert opinion, confirms this absence of tangible results in her patients. Following her recommendation to wait for stronger evidence before investing in these molecules is therefore a very wise approach.
Slow walking (particularly on a walking desk) does not replace a proper sports or cardio session, but it is essential for reducing cumulative sitting time (beyond 6 to 8 hours per day), a major risk factor that acts independently of your regular physical activity level.
The claim that prolonged sedentary behavior poses a distinct risk, even for active individuals, is solidly validated by science. The meta-analysis of observational studies by Patterson et al. (2018) confirms a marked increase in cardiovascular risks beyond 6 to 8 hours of sitting per day. Furthermore, a large-scale meta-analysis led by Ekelund (2016) shows that a volume of daily exercise very difficult to achieve is required to completely erase the effects of a day spent sitting at a desk. Regarding slow walking, research confirms it is not intense enough to improve overall cardiorespiratory endurance. However, several randomized clinical trials prove that these light interruptions to sitting are sufficient to optimize blood sugar and fat management after meals. The creator's message is therefore particularly accurate and scientifically rigorous.
To maintain hormonal balance and metabolic health, the classic 'eat less, move more' approach is insufficient or even counterproductive. One should prioritize a diet rich in healthy fats, protein, and especially fiber, while avoiding sacrificing the latter in favor of an excess of protein.
The recommendation not to exhaust oneself with exercise while in a caloric restriction is validated by science: a consensus from the Endocrine Society (2017) confirms that a severe energy deficit directly disrupts hormones related to fertility and vitality. Furthermore, healthy fats are essential as they serve as building blocks for hormones, while fiber supports the estrobolome (the gut bacteria that regulate estrogen), as highlighted in an observational study published in The Journal of Nutrition. However, the claim that sacrificing fiber for protein is the current 'biggest mistake' among women is more of an expert opinion and lacks comprehensive comparative data. Nevertheless, the approach of nourishing the body to stabilize hormones rather than imposing intense physical stress on it rests on very solid biological foundations.
To best navigate menopause and protect long-term vitality, four lifestyle pillars should be prioritized: engage in 150 minutes of cardiovascular activity per week, perform muscle strengthening twice a week combined with sufficient protein intake, and sleep 7 to 8 hours per night.
The creator draws on a recent observational study in the journal *Menopause* showing that few women meet these goals post-menopause. The figures regarding the decline in bone density and muscle strength during this period are consistent with longitudinal studies on the supportive role of estrogen. The impact of resistance training on longevity (a 10-20% reduction in all-cause mortality risk) is robustly supported by a meta-analysis by Momma et al. (2022) in the *British Journal of Sports Medicine*. Regarding protein, recommendations from the international *PROT-AGE* research group effectively advise aiming for more than 0.8 g/kg to maintain muscle mass with age. As for sleep, clinical imaging work (notably by Shokri-Kojori et al., 2018) confirms that deep rest helps clear metabolic waste from the brain, although the direct link to long-term cognitive decline is still under study. The discourse is particularly balanced, as the creator herself points out that this research describes strong associations rather than absolute proof of cause and effect.
Endometriosis does not automatically disappear with menopause, pregnancy, or a hysterectomy; although hormonal fluctuations may alleviate symptoms, tissue sensitivity and discomfort can persist.
This clarification is scientifically very robust and challenges deeply ingrained misconceptions. A systematic review published by the team led by researcher Haas (2020) confirms that this hormone-sensitive tissue can persist and generate discomfort in 2 to 5% of women after menopause. Furthermore, ESHRE guidelines (expert consensus) maintain that removal of the uterus or the natural decline of hormones does not guarantee the disappearance of sensitive areas, as the latter can sometimes produce their own hormonal signals locally. As for pregnancy, observational studies show that the relief experienced is often merely a temporary pause linked to the absence of cycles, without permanently eliminating the origin of the imbalance. The creator's explanation is therefore perfectly accurate and aligned with current knowledge.
Our gut microbiota plays a major role in hormonal balance by regulating the reabsorption of our estrogens (about 40% of which pass through the intestine) and by harboring the production of 95% of our serotonin, a process that can be disrupted by inflammation.
The idea that the gut influences estrogens is based on a real scientific concept called the "estrobolome," described notably in a review by Baker et al. (2017) published in *Maturitas* (based on observational studies). Certain bacteria do indeed produce enzymes that reactivate estrogens so they can be reabsorbed by the body, although the specific figure of 40% remains a general estimate. Regarding serotonin, it is accurate that nearly 90% to 95% of this molecule is produced in the gut, as confirmed by a study by Yano et al. (2015) in *Cell* (mechanistic evidence). However, it must be clarified that this intestinal serotonin does not directly cross the blood-brain barrier to affect mood, even though there is indirect communication with the brain. Finally, the fact that inflammation diverts tryptophan (the basic component of serotonin and melatonin) toward other pathways is a well-documented biochemical phenomenon, summarized by O'Mahony et al. (2015) in *Behavioural Brain Research*.
To assess and preserve women's heart health, it is necessary to go beyond standard cholesterol screenings and account for their unique biological risk factors, such as pregnancy history, menopausal fluctuations, and inflammatory or hormonal imbalances.
This global perspective is solidly supported by contemporary longevity science. A major scientific review published by Appelman and colleagues in the *European Heart Journal* (2025) confirms that female reproductive life events, such as pregnancy complications or early menopause, are major indicators of heart health. Furthermore, a meta-analysis of observational studies led by Wu and his team in the *BMJ* (2017) demonstrates that difficulties experienced during maternity nearly double the risk of subsequent cardiovascular frailty. Hormonally-based conditions like polycystic ovary syndrome and immune dysregulation also maintain an environment conducive to internal stress, which influences vascular vitality. By suggesting that the classic assessment grid, modeled on male biology, creates blind spots for women's well-being, the creator aligns perfectly with the latest scientific consensus. There is no exaggeration here: integrating these hormonal and personal markers allows for a much more preventive and personalized approach.
To optimize your brain health and preserve your memory, the most effective approach is to combine four key lifestyle habits: regular physical activity, adopting the MIND diet (green leafy vegetables, berries, nuts), taking care of your heart, and stimulating your mind through intellectual activities and social engagement.
The idea of combining multiple lifestyle habits to support brain health rests on a serious foundation, notably inspired by large randomized controlled trials (RCTs) such as the American US POINTER study, recently shared in JAMA. The MIND diet, rich in green leafy vegetables, berries, and healthy fats, is supported by benchmark observational studies that show a strong link with the preservation of mental acuity. The creator accurately notes that the most impressive figures (such as the 56% greater protection) come from observational studies, which indicate a strong correlation without being an absolute promise of causality. Furthermore, the benefit of stimulating one's mind and taking care of cardiovascular health from midlife onward is validated by long-term cohort studies for maintaining intellectual vitality. While no single miracle solution exists, this comprehensive strategy of accumulating habits remains the most robust according to research for optimizing cerebral well-being over the years.
After age 40 and during menopause, it is necessary to adapt one's habits by widening one's eating window to consume enough protein, fiber, and nutrients, while attending to one's evening routine to reduce stress.
Research confirms that the transition to menopause alters stress regulation, metabolism, and sleep. The long-term observational study SWAN (Study of Women's Health Across the Nation) clearly associates this period with increased stress sensitivity and sleep disturbances. To address this, a systematic review published in Nutrients (2022) shows that sufficient protein and fiber intake is essential for maintaining muscle mass and satiety in mature women. Avoiding overly strict fasting by widening the eating window to ensure these intakes is an approach validated by randomized clinical trials (RCT) on nutrition. Finally, the importance of reducing stress in the evening via relaxation rituals is supported by the National Sleep Foundation's recommendations (expert consensus) to optimize sleep quality.
Stress intensifies during perimenopause due to hormonal fluctuations (estrogen) that alter brain chemistry and increase cortisol. To manage this, previous methods are no longer sufficient, and it is necessary to adopt new relaxation micro-habits (box breathing, outdoor walking, journaling).
Estrogen fluctuations during the hormonal transition do indeed influence brain regions managing emotions, as confirmed by a literature review published in *Frontiers in Neuroendocrinology*, which shows that these variations alter stress sensitivity. Furthermore, the link between stress, elevated cortisol, and changes in sugar regulation (insulin sensitivity) at midlife is documented by observational studies, notably in the *Journal of Clinical Endocrinology & Metabolism*. As for the proposed wellness solutions, box breathing and nature breaks have been the subject of randomized controlled trials (RCTs) synthesized in a meta-analysis in *Scientific Reports*, proving their effectiveness in soothing the nervous system. Nevertheless, the assertion that old stress management methods systematically fail is an interesting field observation, but it lacks standardized scientific evidence. Overall, this approach scientifically validates a real experience while proposing accessible calming rituals.
Pelvic pain and cycle disorders (such as fibroids or endometriosis) affect a vast majority of women, yet they should not be trivialized or ignored; they require attentive listening and an active search for solutions rather than simply 'living with it'.
This publication highlights an epidemiological reality widely validated by science: female discomfort is extremely widespread but too often minimized. Regarding fibroids, scientific data confirm the figures put forward: a major observational study published by Dr. Baird in the American Journal of Obstetrics and Gynecology shows that nearly 70 to 80% of women develop them before the age of 50. Likewise, diagnostic delays for endometriosis are well-documented, with a large international observational study led by Dr. Nnoaham having estimated this waiting period at approximately 7 years. Finally, the assertion that 90% of women will face a menstrual or pelvic disorder is consistent with research on dysmenorrhea (menstrual pain), a synthesis of epidemiological data by Dr. Ju showing that it affects up to 90% of young women. The call to stop normalizing pain and to seek appropriate support is therefore fully supported by science.
What's more nuanced than that
Aim for an estradiol level of approximately 60 pg/mL (generally achieved with a 0.05 mg patch) during menopause to optimize long-term heart and bone protection, ideally starting within 10 years of the cessation of periods.
The analysis by Piette et Simon (2026) skillfully cross-references data from rigorous clinical trials (RCT) such as KEEPS and ELITE to identify this 60 pg/mL threshold, which offers a fascinating perspective on female longevity. Science strongly validates the 'window of opportunity' concept: initiating hormonal support before age 60 or within 10 years post-menopause shows clear protective effects on vessels and bones in these randomized controlled trials. However, targeting a specific number via regular blood tests is not yet validated by global research. Expert consensus reminds us that blood hormone levels fluctuate naturally and that benefits are measured primarily by felt well-being rather than a number on paper. Furthermore, while the protective effect on bone structure is widely recognized, the use of hormonal support solely for heart prevention is not yet validated by health authorities, due to a lack of direct evidence regarding the reduction of major cardiac events. It is, therefore, a captivating scientific signal that paves the way for future personalization, even if it precedes current recommendations.
The use of vaginal estrogen in women prone to frequent urinary tract infections may dramatically reduce the risks of systemic infection, hospitalization, and mortality.
The creator relies on a large observational study (based on the Epic Cosmos database analyzing nearly 1.9 million women) that shows a dramatic association between the application of vaginal estrogen and a reduction in hospitalizations or systemic infections. In terms of wellness science, the efficacy of local estrogen in restoring the intimate ecosystem and spacing out recurrent infections is widely demonstrated by randomized controlled trials (RCTs) and supported by expert recommendations. However, presenting this local treatment as a direct shield against mortality remains an extrapolation. As the creator also notes with great rigor, because the study is observational, it is subject to the healthy user bias: women who have access to this treatment often benefit from more attentive overall healthcare. It is therefore an excellent tool for comfort and local prevention, but it cannot yet be scientifically stated that it directly prevents death.
The transition to menopause naturally leads to a decrease in vitamin D and an increase in blood fats (triglycerides), independent of lifestyle. To address this, it is recommended to have your levels tested, then supplement with 4000 IU of vitamin D, vitamin K2 (to direct calcium toward the bones rather than the vessels), and 2 g of omega-3 in re-esterified (rTG) form for cardiovascular balance.
The increase in blood fats during menopause is a well-documented reality: the longitudinal observational SWAN study confirms that the hormonal transition negatively influences this profile, independent of age or weight. To address this, the efficacy of omega-3 is solid: a meta-analysis of randomized clinical trials (RCT) from the American Heart Association shows that intakes of 2 to 4 g per day significantly reduce triglycerides. Furthermore, small clinical trials confirm that the re-esterified (rTG) form offers better absorption than cheaper forms. Regarding vitamin D, the 4000 IU dose is safe and corresponds to the daily upper limit recommended by health authorities (NIH). Conversely, the idea that vitamin K2 prevents the accumulation of calcium in blood vessels in humans relies primarily on theoretical models; current randomized clinical trials do not yet formally confirm this cardiovascular protective effect.
Taking progesterone in the evening helps restore calm, deep sleep, soothes cycle-related discomforts (premenstrual syndrome), and protects uterine balance when used in combination with estrogens, with the option of vaginal application in cases of sensitivity.
The effect of micronized progesterone on sleep quality is supported by randomized clinical trials (RCTs), such as the study by Caufriez et al. (2011), showing that it interacts with brain relaxation receptors to promote deeper rest. Its essential role in maintaining the comfort and protection of the uterine lining when using estrogens is also firmly validated by large clinical trials (such as the landmark PEPI study). The alternative of vaginal administration to bypass digestive discomfort or excessive drowsiness is based on observational studies and expert opinion, which confirm good local absorption. However, the beneficial effect on premenstrual dysphoric disorder (PMDD) is overstated: reviews of the scientific literature indicate that individuals with PMDD often exhibit abnormal sensitivity to progesterone fluctuations, and that adding it can sometimes exacerbate mood swings rather than soothe them.
The drop in estrogen during the menopause transition deprives the body of a natural protective hormone, which promotes the onset of joint discomfort, stiffness, and frozen shoulder (the "musculoskeletal syndrome of menopause").
It is quite accurate that the drop in estrogen is closely linked to an increase in joint sensitivity, as these hormones play a protective role for our tissues. Furthermore, an analysis from the Women's Health Initiative (WHI) randomized clinical trial shows that hormonal support can significantly improve joint comfort in menopausal women. Additionally, observational studies published in the journal Climacteric confirm that a large majority of women experience stiffness and physical discomfort during this transition. However, the term "musculoskeletal syndrome of menopause" is a recent and popularized phrasing that has not yet been officially standardized by the scientific community. Finally, while frozen shoulder often affects women in this age group, its direct and unique link to the decline of estrogen alone still lacks solid evidence, as other mechanical or metabolic factors come into play. This perspective nevertheless remains very interesting for encouraging a comprehensive approach to movement and flexibility during this period of life.
Adopt a three-step approach to stress: eliminate avoidable triggers, take a 20-minute daily break without distractions to regulate cortisol, and replace compensatory behaviors (snacking, screens) with physical movement (walking, squats) to utilize the sugar released by stress.
The idea of actively reducing sources of daily tension is based on solid foundations in behavioral psychology for maintaining mental balance. As for the 20-minute break, a cohort study published in *Frontiers in Psychology* (Hunter et al., 2019) confirms that a 20-minute period of disconnection (such as sitting in nature or walking) significantly lowers cortisol levels. Using movement to consume circulating sugar is also very consistent: a meta-analysis of randomized controlled trials (Buffey et al., 2022) demonstrates that brief sessions of walking or light bodyweight exercise help capture blood sugar through muscle contraction. The concept of a 'cortisol reset' is, however, a somewhat simplified image, as this hormone follows a natural 24-hour biological rhythm that does not reset on demand. Finally, while short-term physical activity supports energy regulation, presenting these micro-movements as a direct bulwark against insulin resistance linked to chronic stress remains an encouraging extrapolation that is still poorly documented over the long term.
Happiness follows a U-shaped curve throughout life, reaching its lowest point (the nadir) around age 47-48—a period that coincides with the peak of perimenopause—before rising steadily thereafter.
The concept of the U-shaped happiness curve is supported by large observational studies, notably the work of economist David Blanchflower published in the Journal of Population Economics, which indeed identifies a low point in well-being around age 47-48 in developed countries. This transition often coincides with periods of significant hormonal variation and midlife stress. However, research is not unanimous: longitudinal studies conducted by psychologists like Nancy Galambos suggest that the trajectory of happiness is more complex and does not systematically follow this U-shape for everyone. Furthermore, although the parallel with perimenopause is clinically highly relevant to explain this feeling of chaos, the data on the happiness curve come from global demographic surveys and not from biological analyses measuring the direct impact of hormones. This phase should therefore be understood as a general trend and an opportunity for personal re-evaluation rather than as an absolute biological inevitability.
Optimism is only 25% genetic (notably linked to the oxytocin receptor gene); the remaining 75% is cultivated as a skill by learning to identify pessimistic thoughts and by strengthening social connections to preserve emotional well-being.
Behavioral genetics research, particularly observational twin studies popularized by psychologist Martin Seligman, confirms that optimism is approximately 25% heritable. Furthermore, a key observational study led by Shelley Taylor and published in PNAS indeed associates variations of the oxytocin receptor gene (OXTR) with optimism and self-esteem. The idea that optimism can be learned through connection practices and cognitive reframing is solidly supported by numerous randomized controlled trials (RCTs) in positive psychology. However, declaring as an absolute fact that unmanaged pessimism will inevitably lead to emotional distress or a depressive state is an exaggeration. Observational data show that pessimism is a significant risk factor for mood, but not an absolute certainty. This perspective nonetheless remains a compelling invitation to train our minds and strengthen our social bonds on a daily basis.
Avoid unnecessary antibiotics to preserve the gut ecosystem, and regenerate it using a simple triptych: fiber to nourish good bacteria, fermented foods to introduce new ones, and proteins.
The disruptive impact of antibiotics on the microbiota is scientifically proven: an observational study conducted by Rashid et al. (2015) confirms that certain bacterial populations struggle to fully recover even one year after treatment. Similarly, the hypothesis of a loss of microbial diversity over generations in modern societies is supported by observational research from Justin Sonnenburg's team at Stanford. Regarding reconstruction, the value of fiber and fermented foods is based on solid foundations; a randomized controlled trial (RCT) conducted by Wastyk et al. (2021) demonstrated that a diet rich in fermented products significantly stimulates microbiota diversity while reducing inflammation. Conversely, the claim that the gut "loves" proteins needs to be nuanced, as observational data suggest that an excess of animal proteins can sometimes promote a less protective microbial profile. Finally, the influence of the microbiota on hormonal balance (notably via the estrobolome) is a fascinating field but still relies mainly on expert opinions and biological models, with direct clinical evidence in humans remaining limited.
Frequent nighttime awakenings between 2 a.m. and 5 a.m. during perimenopause are explained by a dual phenomenon: variations in estrogen disrupt cortisol regulation (the alertness hormone), and the decrease in progesterone reduces the body's ability to relax, all of which is amplified by the daily mental load.
Sleep disturbances during perimenopause are widely documented, notably by the large-scale observational study SWAN (Study of Women's Health Across the Nation), which confirms a significant increase in nighttime awakenings during this transition. The link between the decline in progesterone—which naturally promotes relaxation and calmness—and difficulty staying asleep rests on well-established scientific foundations. Furthermore, observational work published in the Journal of Clinical Endocrinology & Metabolism indicates that estrogen variations alter the body's sensitivity to stress, which can disrupt the natural rhythm of cortisol. Nevertheless, specifically targeting the 2 a.m. to 5 a.m. window as being purely caused by a hormonal cortisol spike is a simplification. In reality, it is often variations in body temperature (sometimes imperceptible hot flashes) that wake the body first, subsequently causing a secondary increase in alertness. The impact of daily stress described by the creator remains, however, a major and scientifically validated factor influencing the overall quality of rest.
