HRT for menopause may not help with mental health or sleep says a large 2026 analysis

Within months of a landmark 2002 study that indicated HRT harms, sales dropped by about half

In the early 2000s, Women's Health Initiative studies indicated HRT increased risk of breast cancer, heart disease, and stroke in some women—so many physicians stopped prescribing it to help with menopause symptoms. But further research has concluded that much of the elevated risk was overblown and that it was also disproportionately seen in women in their 70s who had been taking an older HRT formulation.

There are multiple HRT options to treat menopause and perimenopause symptoms

This lengthy video features a board-certified OB/GYN based in Texas who provides a thorough overview of the different formulations for HRT, used to treat symptoms including hot flashes, vaginal dryness, and mood swings, and the pros and cons of each. She also discusses modern synthetic options versus the older formulation extracted from the urine of confined pregnant horses.

27% of US menopausal women used estrogen in 1999, but by 2020 that number was under 5%

The fallout of studies in the early 2000s linking hormone therapy for menopause and elevated cancer, stroke, and other health risks meant that even decades later—yet before the FDA removed its black box warning in 2025—use of HRT remained extremely uncommon. (Some users may experience a paywall.)

HRT patches are popular partly because they have lower blood clotting risks than oral estradiol

Women taking estradiol for menopause or perimenopause are sometimes told oral HRT is not an option for them because it increases blood clot risks. But a large analysis in 2019 concluded that other forms of the HRT, such as the patch, creams, and gel, do not.

How menopause affects mental health

Menopause, a natural biological process, occurs in three stages: perimenopause (hormone fluctuations), menopause (end of menstrual cycles), and postmenopause (12 months without menstruation). Hormonal shifts during this time can affect neurotransmitters, increasing the risk of mood disorders.

The gaps in menopause research and their effects

Nearly all studies (99%) researching the biology of aging don’t consider menopause in their setup. A Harvard professor noted that about 75% of aging-related diseases are likely influenced by menopause. In this article, she discusses how gaps in research are negatively impacting how the medical system can effectively treat aging women. Read her analysis of the issue here.

Menopause can exacerbate anxiety

Some research shows that menopause can fuel anxiety and also that pre-existing anxiety can boost the chances of experiencing other menopause symptoms, including hot flashes, insomnia, and brain fog. But treatments including hormone replacement therapy, breathing exercises, and other forms of exercise can alleviate some of these symptoms.

It's never too late to start hormone replacement therapy for menopause symptoms

This board-certified gynecologist discusses how it's ideal to start estradiol as soon as possible after menopause to maximize its benefits, but that if older women have healthy hearts they can still start these medications later, in consultation with their doctors, and the products could be useful if women are continuing to suffer from symptoms of menopause or want to fight bone loss.

MS Drugs reduce inflammation, helping reduce relapses and slow disease progression

Disease-Modifying Drugs calm the body's inflammatory response to help stave off relapses—when new or existing MS symptoms show up for a day or longer. Avoiding smoking, exercising, reducing stress via mindfulness, checking for vitamin D deficiencies, drinking more water and eating well, all can slow disease progression. [The jury's still out on if HRT around the time of menopause may reduce dementia risk](https://www.thelancet.com/journals/lanhl/article/PIIS2666-7568(25)00122-9/fulltext) Estrogen can reduce inflammation and support neural growth in the brain, and some research has suggested that beginning hormone replacement therapy around menopause—versus later in life—reduces Alzheimer's disease risk. Still, a recent systematic review concluded that taking HRT didn't affect dementia risk, regardless of when women started taking it, so the science remains unsettled.

Gender-affirming hormone therapy cues changes similar to puberty

When HRT is part of gender affirmation care, people receive regular doses of estrogen or testosterone to alter hormone levels to more closely align with those of cis individuals of that biological sex. HRT may affect voice pitch, body hair, bone density, and more. Many of those changes are not reversible with the cessation of therapy, though the effects may diminish.

Menopause may become a $600B industry

Companies marketing products and supplements to alleviate menopause symptoms and make life easier during this life stage have become a gold mine. This 2022 article explores how and why companies have swooped into this space, and whether you should trust them or not.

Health problems are being misdiagnosed as perimenopause symptoms

Symptoms of menopause and perimenopause (the premenopause period) can be varied enough that clinicians dismiss them in patients in their mid-30s and onward as just a symptom of hormone level change. In this story, a woman's itching was dismissed as a hormonal change, but after two years and 11 separate doctor consultations, was diagnosed as cancer. (Some users may experience a paywall.)

Estrogen is a really important hormone for men, too

Many people may be familiar with the idea that too much estrogen can cause infertility and other complications, including erectile dysfunction, but too little estrogen is also a significant medical concern because it can result in a reduced sex drive and limit overall growth.

Studies suggest when you sleep is as important as how much you get, and syncing with your circadian rhythms may lead to less fatigue and improved long-term health outcomes

The overlooked physical causes of insomnia

Persistent lack of sleep is dangerous for anyone, but women are especially unlikely to have their symptoms taken seriously. This article highlights the physical causes of insomnia—a condition often written off as solely psychological—and the importance of early diagnosis. The writer, Courtney Maum, was diagnosed with an anterior nasal valve collapse as the source of her insomnia.

Yoga is believed to improve mental health, but studies are not definitive

Many think that yoga's combination of stretching, focused breathing, and contemplation help treat depression and anxiety, but the data has often relied on small, homogenous sample sizes.

Obsessing over sleep metrics leads to worse sleep quality

Over one-third of Americans have used wearable technology to track their sleep, and the anxiety over having perfect sleep data, or orthosomnia, has made getting a good night's sleep more difficult. Experts agree that most devices cannot correctly assess sleep details, making the data unreliable.

Inflammation appears to cause specific symptoms of depression

A large analysis of existing studies published in 2021 found that systemic inflammation is associated with fatigue, appetite changes, and sleep disruption, rather than some of depression's broader symptoms including hopelessness about the future, or feeling fearful. This may suggest that inflammation influences specific symptoms of the condition, rather than the disease as a whole.

Headache disorders have historically been neglected and under-researched

Confusion between the variety of headaches—from mild discomfort to debilitating pain—and gender bias—migraines primarily affect women—have led to widespread misunderstandings of the medical issue. Medical students in the US may get as little as 30 minutes of instruction on the three major types: migraines, cluster headaches, and tension-type headaches.

1 in 10 US adults are taking medication for depression

A US government report indicates that about 10% of US adults took prescription medication for this disorder in 2023. Women, at 15.3%, were more than twice as likely to take one of these medications than the 7.4% of men.

Heatstroke treatment guidelines were built almost exclusively on research in men

Protocols for the standard treatment recommendation for heatstroke—whole-body cold water immersion—were built based on studies almost entirely in men. The research wasn't replicated in women, who typically cool faster than men during cold water immersion, raising questions about standard protocol safety for women, due to the risk of overcooling.

Women more likely than men to report strain of being a caregiver

A Pew Research Center caregiver analysis from 2026 indicates that, though men and women both say caring for aging parents improved their relationships with their parents, women are more likely than men to report that it had a negative impact on their emotional well-being and physical health.
