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.

The body’s second largest organ, the liver is responsible for more than 500 bodily functions. One of the liver’s greatest threats is nonalcoholic fatty liver disease (NAFLD), an umbrella term that includes several forms of liver disease. Most people with NAFLD have a type known as simple fatty liver. However, up to 20% of people with NAFLD develop inflammation in the liver known as nonalcoholic steatohepatitis (NASH). Left unchecked, this more dangerous form can progress into fibrosis (scarring) and potentially cirrhosis (severe scarring and liver damage). Lifestyle changes, such as weight loss, increasing exercise, and adopting a plant-based diet are the best means to manage and prevent NAFLD.

Peyronie’s disease, a condition marked by extreme curvature of the penis, affects about 3% to 10% of men, usually between the ages of 45 and 60, but also can occur in men older than 60. There is no cure for Peyronie’s, and the condition often does not improve on its own, but in mild cases men can maintain a regular sex life. If the curvature is severe, making erections or intercourse painful, treatment may help. Options include traction therapy, drug injections, and surgery.
