The body doesn’t age in a straight line. Each decade brings quiet shifts—some expected, others easy to miss until they’re already underway. Doctors who study aging say these changes often arrive earlier than most people realize, and the right moves now can soften their impact later.
Your 40s: The body’s first real wake-up call
Perimenopause usually starts in the late 30s or early 40s, long before menopause itself. Estrogen levels swing wildly, bringing hot flashes, mood swings, and periods that vanish for months only to return without warning. The changes aren’t limited to these symptoms.
Vaginal dryness can begin years before menopause, making sex uncomfortable or even painful. Tissue thins, loses elasticity, and dries out as estrogen production slows. Sheryl Kingsberg, a behavioral medicine specialist at University Hospitals Cleveland Medical Center, says many women assume a lubricant will solve the problem. It may not. Topical estrogen—delivered through a ring, cream, or suppository—is the standard treatment, with minimal risk since almost none enters the bloodstream.

Kingsberg also recommends using a vaginal moisturizer twice a week. For sex, she and Lauren Streicher, an OB-GYN at Northwestern University, advise against water-based lubricants with glycerin or propylene glycol. These ingredients can worsen dryness by pulling moisture from tissue. A silicone-based product or a water-based one with an osmolality below 380 mOsm/kg is a safer choice.
Pelvic floor weakness often appears in the 40s. Laughing, coughing, or sneezing can trigger leaks, a side effect of pregnancy, childbirth, and hormonal shifts. Medications help, but a pelvic floor physical therapist can prevent the issue from worsening with age.
Brain health becomes a priority in this decade. Research links menopause to early brain changes that may later contribute to Alzheimer’s. Cardio exercise, a plant-rich diet, and consistent sleep can delay cognitive decline. Preventive screenings also increase: colonoscopies, mammograms, and the HPV vaccine—even for women in their 40s—offer protection against cervical cancer and other HPV-related diseases.
Your 50s: The decade when past choices catch up
Heart disease risk spikes in the 50s as estrogen, which protects cardiovascular health, declines. By 55, more women than men develop high blood pressure or high LDL cholesterol. A mix of diet, exercise, stress management, and medication can help manage these conditions.

Your 60s: The social side of aging
Brain health remains a focus in the 60s, but the best strategies go beyond crossword puzzles. Learning a new skill—quilting, dancing, pickleball, or a language—creates new neural connections. Social ties matter just as much. Loneliness and isolation increase the risk of dementia, heart disease, stroke, diabetes, depression, and early death.
Gail Saltz, a psychiatrist at Weill-Cornell Medical College, says making new friends becomes harder in the 60s. Retirement, empty nests, and relocations shrink social circles. She suggests joining groups tied to hobbies or faith communities, and making time for casual interactions like chatting with a barista or a stranger in line. These small exchanges keep the brain engaged.
Exercise shifts toward functional movement—strengthening grip and improving flexibility, both linked to longevity. Falls become a serious risk, so balance training and home safety checks are critical. Libido can fluctuate, but treatments like testosterone, vaginal DHEA, or the nonhormonal drug flibanserin may help. Condoms remain important; STI rates among adults 65 and older have more than doubled in the past decade.
Your 70s and beyond: The quiet risks
Hearing and vision often decline in the 70s, but the consequences extend beyond missing a conversation or struggling to read. Uncorrected hearing loss is linked to dementia, isolation, and a shorter lifespan. Melissa Karp, an audiologist in Charlotte, says it also affects self-care. If someone can’t hear their doctor’s instructions, they’re less likely to follow them. Falls become more likely too.

Hearing aids are smaller, more affordable, and less stigmatized than ever. Vision problems, like cataracts, can often be corrected with surgery, eliminating the need for glasses. Weight becomes less of a concern—research suggests a slightly higher BMI in older adults can be protective, as long as obesity isn’t a factor.
Sex doesn’t have to end with age. Hormonal changes might make intercourse uncomfortable, but trying new positions or exploring other erogenous zones can help. Kingsberg emphasizes that gynecologists should address sexual health at any age. If they don’t, patients should find a doctor who will.
The ovaries, long after their reproductive role ends, still influence how women age. Jennifer Garrison, who studies ovarian aging at the Buck Institute, describes them as a “second brain,” sending hormones that influence bones, heart, liver, muscles, and skin. When ovarian function declines, the rest of the body ages faster. Menopause can accelerate cellular aging by nearly 6%.
