Bedbugs are tiny, flightless insects that feed on the blood of sleeping people and animals. After being nearly eradicated more than 50 years ago, bedbugs are now more resistant to pesticides and have resurged over the past decade. Bedbugs don't transmit diseases, but some people have an allergic response to their saliva. People can keep bedbugs from getting into their home by inspecting hotel bedding, unpacking clothes directly into a hot washer or dryer, keeping coats isolated while visiting others, and inspecting used furniture before bringing it home.

The use of sleep tracking devices is increasing, but using a sleep tracker can contribute to anxiety and insomnia. Data from the device can influence how a person feels after awakening, even if the data aren't accurate.

A special form of cognitive behavioral therapy called CBTi is designed to improve insomnia and anxiety around sleep.

People can reduce their fall risk by doing strength and balance exercises, getting regular vision and hearing exams, reviewing their medications, and keeping floors clutter-free.

Some people have poor circulation, but if your fingers pale and go numb when exposed to quick changes in temperature, it could be Raynaud's phenomenon, a different kind of circulation problem.
