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.

A large, randomized Harvard study published online Dec. 21, 2021, by JAMA found that taking fish oil supplements didn't prevent depression in otherwise healthy older adults.

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.

Burping is often seen (and heard) as something rude and crude, but it serves an essential purpose by preventing the stomach from overinflating with air from eating.

Allergies that cause nasal congestion, sneezing, and a runny nose (what doctors call allergic rhinitis) can cause more frequent and louder snoring. Treating allergic rhinitis can reduce snoring and other symptoms related to poor-quality sleep.

Treating insomnia with cognitive behavioral therapy (CBT-I) may reduce the risk of depression in older adults. CBT-I seeks to modify thoughts and habits to improve sleep. It outperformed a more traditional insomnia treatment, sleep education therapy (SET), which seeks to change environmental factors and behaviors that contribute to poor sleep.

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.
