The number of people taking large amounts of melatonin (more than 5 milligrams per day) is at an all-time high. However, the amount in a supplement can be significantly higher than what the label shows. This can cause people to take too much, especially since many use melatonin regularly.

The medical world agrees that daily aspirin can help people with cardiovascular disease lower their risk of heart attacks and strokes. However, most people over age 70 without cardiovascular disease should avoid aspirin as a way to prevent a heart attack or stroke. Even if a person has taken aspirin for a long time as primary prevention of heart disease, it's time to talk to your doctor about potentially stopping it.

A placebo response (improvement in symptoms from the act of taking a drug independent of its biological effects) is not fully understood. Still, placebos are commonly used in clinical trials to test the effectiveness of a specific therapy.

A study published online Jan. 24, 2022, by JAMA Internal Medicine estimated that increasing physical activity by 10, 20, or 30 minutes a day would decrease the number of annual deaths by 7%, 13%, or 17%, respectively.

A study published online Feb. 16, 2022, by the European Heart Journal suggests that the prevalence of statin intolerance is much lower than commonly cited. Instead of 50%, the study found that prevalence is 6% to 10%.

A study published online Jan. 15, 2022, by Appetite suggested that people's expectations of how full they will feel after eating can influence their actual food intake.

The fear of falling can lead to a heightened sense of caution and less physical activity—which can actually increase the risk of falling. To reduce the fear of falling, a person must address underlying conditions, such as poor eyesight or joint problems. It also helps to work with a physical therapist to improve balance, gait (walking pattern), muscle strength, flexibility, and range of motion. When physical therapy ends, one must continue doing strength, stretching, and balance exercises at home in order to keep fear at bay and reduce fall risk.

Studies suggest that the world is facing two different dementia trends. One is that dementia rates are falling steadily in the United States and Europe. The other is that the number of dementia cases globally is rising, and will likely triple in the next 30 years, mostly due to population increases. People can try to reduce their dementia risk by adopting a healthy lifestyle that includes lots of exercise, a healthy diet, at least seven hours of sleep per night, limited alcohol consumption, socializing, improved balance, stress management, smoking cessation, and control of underlying health conditions.

Gut bacteria may influence our emotions and cognitive capabilities. For example, some bacteria make oxytocin, a hormone the body produces that encourages increased social behavior. Other bacteria make substances that cause symptoms of depression and anxiety. Still others make substances that help people to be calmer under stress. Gut bacteria also have been shown to influence people's vulnerability to certain brain diseases, including Alzheimer's disease, Parkinson's disease, and autism. For example, a substance found in the brains of people with Parkinson's disease (synuclein) is made by gut bacteria and can travel via nerves from the gut to the brain.

Middle-aged men who often feel worried or anxious may be more prone to problems that raise heart disease risk as they age compared with their less-worried peers.
