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.

A 2023 study suggests that eating more red meat—about a one additional serving each day—is linked to a higher risk of developing diabetes than those who eat less.

A pulled muscle sometimes feels similar to a pinched nerve. But muscle pain is usually dull and doesn’t radiate outward, while pinched nerve pain is sharp and burning and extends from one area to another. Pinched nerves can stem from pregnancy, arthritis, or injuries.

Falls are the leading cause of injuries and accidental deaths among Americans 65 and older. Women fall more often than men and are far more likely to show up at an emergency room because of a fall. Women are especially vulnerable to falling due to weaker bones, lower muscle mass, higher rates of incontinence and antidepressant use, and a tendency to multitask. 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.

Compared with people who sit for eight hours daily, people who sit more than 12 hours a day may be more likely to die prematurely. But just 22 minutes of brisk walking or similar activity daily may offset that risk, according to a 2023 study.

When people with atrial fibrillation sleep poorly, they may be more likely to have an episode of atrial fibrillation the next day, according to a 2023 study.

A 2023 study of 93,000 people ages 65 or older found that those who said they had hobbies reported having better health, more happiness, fewer depression symptoms, and higher life satisfaction, compared with those who said they didn’t have hobbies.

A 2023 study of 1.5 million people found that those who had uncontrolled high blood pressure or diabetes prior to getting COVID-19 had increased risks for COVID complications (such as hospitalization or being on a ventilator), compared with people whose high blood pressure or diabetes was well controlled.

For the first time, consumers can order a blood screening for Alzheimer’s disease. The screening looks for two types of brain proteins, one of which is associated with Alzheimer’s. Doctors have concerns about the screening: it’s not FDA-approved, there’s little information about its accuracy, and it can take a few days to speak with a doctor about the results. By comparison, an official Alzheimer’s diagnosis involves a comprehensive evaluation of someone’s current and past health problems, physical and neurological exams, family history, blood tests to rule out hidden conditions that might be causing memory problems (such as vitamin B₁₂ deficiency), and imaging tests.

It takes more than a weekly session with a personal trainer to maximize exercise benefits. Personal trainers recommend that people exercise in between training sessions; do strength training at the beginning of a workout; alternate the muscle groups that get a workout; challenge each muscle group with a variety of exercises; stretch regularly; eat a healthy diet to fuel the body; and exercise purposefully, with a strategic approach that moves them closer to their exercise goals.
