COVID-19 may increase the risk of cardiovascular problems, including heart attack, stroke, pulmonary embolism, atrial fibrillation, and heart failure, up to a year after the infection. But vaccination appears to lower these risks. Getting just one dose of a COVID vaccine may halve the risk of myocarditis, a rare condition that causes inflammation of the heart muscle that can arise after viral infections.

Dry eye syndrome is one of the most common eye problems among older adults. Common symptoms include a gritty feeling in the eyes, sensitivity to light, or fluctuating vision that comes and goes. People with the condition can have good and bad periods, but by following prevention methods and seeking treatment when the disease flares, they can keep dry eye from interfering with their lives.

A 2023 study suggests that some brain changes in people with obesity appear similar to those that occur in people with Alzheimer's disease, the most common cause of dementia.

Travel disrupts many of the body's natural rhythms, including digestion, increasing the odds of indigestion, diarrhea, or constipation. Food and water in developing countries can be contaminated with germs that make traveler's diarrhea more likely.

In a 2023 study of more than 28,000 older adults, those who reported socializing the most frequently lived the longest, compared with people who said they didn't socialize.

A 2023 study shows that avoiding sugary drinks is linked to dramatically lower risks for cardiovascular disease and early death in people who have diabetes. Drinking artificially sweetened beverages in lieu of sugary drinks was also associated with lower risks.

For people who buy over-the-counter hearing aids, getting the devices is only a first step toward better hearing. It takes time to learn how to use, wear, and adjust the hearing aids, especially during the first two weeks. Tips to ease through this adjustment period include wearing devices at home for at least a few hours per day, and longer if possible; allowing soft sounds to be louder than normal at first; and learning to switch device settings for changes in environmental noise, such as going from a quiet street into a noisy restaurant.

Marijuana use, which is rising among older adults, appears to heighten the risk of heart-related problems. Cannabis is known to increase heart rate and blood pressure, although high doses can have the opposite effect.
