The modernization of standard home medical devices has made monitoring health easier than ever. These gadgets include thermometers, scales, blood pressure monitors, and pulse oximeters. Gadget features that are especially helpful for older adults are easy operation and large, lighted readouts.

Many COVID-19 symptoms — such as fever, cough, or muscle aches — overlap with the symptoms of other respiratory conditions, such as influenza, a common cold, or asthma.

A person who's experiencing concerning symptoms of respiratory illness should report them to a doctor.

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.

To promote sounder sleep, people can keep consistent sleep-wake schedules, reduce intake of caffeine and alcohol, and avoid using electronic devices before bed.
