Most adults need seven to nine hours of sleep each night, but more than one-third consistently sleep fewer than seven. Reasons for poor sleep include pregnancy, menopausal night sweats, medication use, sleep disorders, and various illnesses. Sleep deprivation can raise the risks for such conditions as diabetes, certain cancers, obesity, dementia, depression, and heart disease. To promote sounder sleep, people can keep consistent sleep-wake schedules, reduce intake of caffeine and alcohol, and avoid using electronic devices before bed.

Many people have used at-home medical tests to detect COVID-19. Other home tests are available that can screen for, diagnose, and monitor dozens of health conditions, including pregnancy, infections, cholesterol and blood sugar levels, and colorectal cancer.

But test results may be inaccurate or confusing, provoking unneeded or risky further testing or treatment. People should tell their doctors if they use at-home medical tests.

Doctors concentrate on helping men lower their blood levels of low-density lipoprotein (LDL), or "bad" cholesterol, to lower their risk of cardiovascular disease. Lower HDL levels are associated with higher cardiovascular risk. This may be related to HDL's role in helping to remove excess cholesterol in arteries that can lead to plaque buildup and increase the risk of heart attacks and strokes. However, no specific therapies to raise HDL levels have improved outcomes.

People with disabilities or physical limitations can still stay active and get the recommended amount of exercise by participating in adaptive sports and activities.
