Herbal teas, tinctures, and other supplements may help. But talk to your doctor first. Even natural sleep aids can cause side effects or interfere with how your medicines work.

Coronavirus Immunity and Reinfection

Because many people who have COVID-19 have mild or no symptoms, antibody tests may be the best way to find out how far the new coronavirus has spread. These blood tests can show who's been exposed to the virus and who hasn't. The hope is that people who've been exposed to the new coronavirus will have immunity to it. When you have immunity, your body can recognize and fight off the virus that causes COVID-19. But it's possible that people who've had COVID-19 can get sick again -- and maybe infect other people. We don't have enough information yet to know which is the case. But national health organizations are doing research to try to find some answers.

Vitamins You Need as You Age

Older adults have different needs when it comes to vitamins and minerals. For example, the right amount of calcium can help fend off osteoporosis in women. Vitamin D, which helps your body take in and use calcium, also helps prevent bone loss and broken bones in older adults.

Viruses can steal our genetic code to create new human-virus genes

Like a scene out of "Invasion of the Body Snatchers," a virus infects a host and converts it into a factory for making more copies of itself. Now researchers have shown that a large group of viruses, including the influenza viruses and other serious pathogens, steal genetic signals from their hosts to expand their own genomes.

This finding is presented in a study published online and in print June 25 in Cell. The cross-disciplinary collaborative study was led by researchers at the Global Health and Emerging Pathogens Institute at Icahn School of Medicine at Mount Sinai in New York, and at the MRC-University of Glasgow Centre for Virus Research in the UK.
