According to a 2025 study, women who walked at least 4,000 steps per day once or twice a week had a lower risk of cardiovascular disease and early death compared with women who did not reach this threshold.

A 2025 study found that in brain MRI scans, people with any evidence of gum disease were more likely to have higher amounts of a marker for disease in the brain's small blood vessels, compared to people without gum disease.

Daily nasal irrigation (also called nasal rinses) may reduce symptom severity and the duration of a cold. It can also relieve the congestion caused by sinus infections and allergies. It is unclear whether it can prevent colds. By means of a squeeze bottle, neti pot, or battery-powered system, saline (salt water) is inserted into one nostril and flows out the other. It's important to always use sterile water, meaning distilled or cooled boiled water. The rinse helps wash away mucus and some inflammatory chemicals, reducing the swelling that's responsible for congestion.

There are many ways people can meet the national guidelines for weekly activity. While running and walking are popular exercise choices, they are not the only options. Many sports and activities provide a similar heart-pumping workout, such as boxing, swimming, cycling, basketball, dancing, and even pickleball. People can also get creative and do circuit training using gym machines or perform cardio exercises at home.

Ellipticals are stationary exercise machines that simulate walking, running, or stair climbing. They combine cardio with strength training and can simultaneously engage the upper and lower body for a full-body workout. Ellipticals also offer a low-impact exercise, placing less stress on the knee, hip, and ankle joints, which make them ideal for people who have knee or hip osteoarthritis or are recovering from an injury.

A 2025 study identified poor sleep along with high blood pressure, nicotine use, and high blood sugar levels as particularly important factors increasing the long-term risk of heart problems for women in midlife.

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.

Four classes of drugs commonly prescribed to older adults-opioids, benzodiazepines, gabapentinoids, and antidepressants-may be driving the dramatic rise in deadly falls over the past three decades. Known as fall risk-increasing drugs (FRIDs), these drug classes affect brain function and can make people feel sleepy, dizzy, or confused-all of which can leave them vulnerable to falling. People currently taking these drugs shouldn't stop taking them abruptly, as doing so may cause withdrawal symptoms. People should ask their primary care clinician to review all their medications at least once a year.

Elderberry syrup or tea may help reduce the duration and severity of cold and flu symptoms. But the evidence for these benefits is uncertain, since the studies are small and most did not compare elderberry to standard treatments. Claims that elderberry products can prevent viral infections or boost immunity are unproven. Elderberry supplements appear to be relatively safe; in clinical trials, effects such as nausea, vomiting, or diarrhea were mild and rare.

Circadian rhythms, which are hardwired into nearly every cell of the body, regulate the heart and blood vessels. Disruptions to this rhythm-from shift work, poor sleep, or unhealthy habits-can raise the risk of cardiovascular disease. For example, heart attacks are more likely to occur on Mondays than any other day of the week. That's because people tend to stay up later than usual and then sleep in the next day. On Monday morning, when they have to wake up early again for work, the change may cause subtle changes in blood pressure, hormone secretion, and metabolism that raise heart attack risk.
