Waking up in the middle of the night happens to women more often after age 55 due to many factors. These include diminished hormones and circadian rhythm changes. Stress, bladder changes, medications, chronic pain, and alcohol and caffeine use can also contribute. People can break the cycle of nighttime wake-ups by practicing good sleep hygiene, addressing medical issues, trying mind-body techniques such as deep breathing or meditation, and limiting caffeine, alcohol, and heavy evening meals.

Red light therapy involves using devices that emit red or near-infrared light aimed at the skin. It is believed to reduce inflammation and boost production of collagen. Research suggests it can improve an array of skin problems, including fine lines, dark spots, redness, slow-healing wounds, scars, and acne. Unlike ultraviolet light, red light therapy isn’t associated with greater risks for skin cancer. Scientists are still determining the optimal doses of red light therapy for various skin conditions.

A 2025 study suggests that postmenopausal women may be able to lower their blood pressure simply by standing more often each day.

After an FDA panel was convened to review black box warnings on menopause hormone therapy, which includes both systemic and vaginal estrogen treatments, the FDA announced in November 2025 it would remove black box warnings from all hormone therapy products containing estrogen. Women considering hormone therapy should discuss their individual health risks with their doctor — such as a history of heart attack or stroke, a blood clot in the legs or lungs, hormone-sensitive cancer, active liver disease, and overall breast cancer and cardiovascular risks.

A 2025 study found that many people who use a fitness app to track their daily steps were able to maintain or increase their numbers over two years, suggesting the devices may have a long-term effect on motivation.

In a 2025 study, adults 45 and older with a strong sense of purpose were 28% less likely to develop cognitive impairment or dementia compared with individuals who had a low sense of purpose.

People who suffer from chronic insomnia are more likely to develop cognitive problems and score lower on thinking and memory tests compared with individuals without chronic insomnia, a 2025 study suggests.

Diastasis recti occurs when the rectus abdominis muscle — the “six-pack” — separates and leads to a midline abdominal bulge. This might happen because of pregnancy, aging, genetics, excessive abdominal pressure, or abdominal surgery. The bulge becomes more noticeable when lifting heavy objects, getting out of bed, or even performing everyday tasks. The condition usually doesn’t resolve on its own. Working with a physical therapist can help decrease the muscle separation.

A urine test, also known as a urinalysis, can reveal a great deal about a person’s health. The kidneys produce urine to remove excess fluid and waste products from the body. But urine also contains various chemicals, minerals, toxins, bacteria, and red and white blood cells. Analyzing a urine sample with visual, chemical, and microscopic exams can reveal the presence and amounts of these substances, which can provide clues to specific conditions.

Among 12 physical therapy approaches for knee osteoarthritis compared in a 2025 study, three stood out. Knee braces, followed by hydrotherapy (exercise in water) and exercise (strength training and aerobics), were best for reducing pain and stiffness and improving physical function.
