The CDC estimates that 70 million Americans suffer from chronic sleep problems. For some, melatonin is believed to be a safe treatment option because it is a hormone produced by our bodies. But evidence of its effectiveness is lacking, and inconsistent quality of product is a concern.

Platelet-rich plasma injections are used to reduce pain and speed healing for a number of common problems that affect the tendons, muscles, and joints, ranging from arthritis to shoulder pain. But a growing body of research shows that they may not be effective for some conditions, including knee osteoarthritis, ankle osteoarthritis, and Achilles tendinitis. There is some evidence that it may be effective for lateral epicondylitis (tennis elbow). People should consider whether there is a better option before undergoing PRP injections.

Hiking is similar to walking but can be more challenging and can provide a nice change of pace. Walking over uneven terrain typically burns more calories than a walk on a flat surface. It also builds muscle strength and improves balance. A wilderness walk also brings mental health benefits. Choosing a path to a scenic destination may motivate people to go farther and climb higher and increase fitness gains.

A 2021 study found that a low-carb diet may not necessarily be bad for heart health, despite its high saturated fat content. However, the study period was short, and the diet used in the trial was healthier than many low-carb approaches. More research is needed to confirm the results. In the meantime, experts recommend finding a sustainable diet that provides a healthy daily mix of nutritious foods instead of solely looking at carbohydrate content.

Almost 20% of people with hypertension may be taking medications that raise blood pressure, most often pain relievers such as ibuprofen (Advil) and naproxen (Aleve). Other classes, such as certain antidepressants, may also increase blood pressure.

High blood pressure not only can raise risk for a heart attack, but also can affect the brain. Keeping blood pressure normal can make brain injury from stroke less likely to happen and perhaps slow the natural decline in cognitive function. Just like with the heart, the best way to protect the brain from high blood pressure is to lower blood pressure if it's high and keep it as close to a normal level as possible.

An observational study published online Dec. 6, 2021, by JAMA Internal Medicine found that the risk of developing dementia was 29% lower in people who underwent cataract removal, compared with people who didn't have cataracts removed.

In December 2021, the FDA warned consumers about an increase in supplements tainted with harmful ingredients, particularly supplements promising male enhancement or weight loss.

Chronic stress is bad for health. It can trigger physical problems, including chronic inflammation—the persistent activation of the immune system, which sharply raises the risks for many diseases such as dementia, heart disease, or stroke. Ways to reduce stress include living a healthy lifestyle, doing relaxation exercises, stretching, being mindful, taking a brisk walk, reducing loud noise, using laughter, playing soothing music, countering negative thoughts, reaching out for help from a loved one, and using positive self-talk.
