Certain activities like running, stair climbing, or kneeling may lead to knee pain. But evidence suggests that regular activity or exercise is unlikely to cause actual knee damage. Learn how to keep active and avoid knee pain.
Some medication instructions are vague and confusing. Examples include “take once daily,” “take with food,” and “take with water.” When someone is unsure exactly how to take a medication, even if it’s already been explained, it’s best to ask for clarification. Ideally this happens when a doctor writes the prescription, but it’s okay to call and ask later. It may also be helpful to ask a pharmacist for the directions, either when picking up a medication or on a later call.
A 2023 analysis of nearly 300 randomized trials found that several types of exercise were effective in lowering resting blood pressure. Exercise types included aerobic exercise, high-intensity interval training, dynamic resistance training, isometric exercise training, and combined training (aerobic exercise plus one of the other types of exercise). People who are over age 50 and have not been exercising much should check with a doctor before beginning a regular exercise program, since some types of exercise may not be right for them.
The reason for weight gain isn’t always as obvious as inactivity or a poor diet. Weight gain can stem from many other causes. For example, it might reflect age-related physiological changes such as muscle loss, poor sleep, or changes in sex hormone levels; underlying conditions such as diabetes or sleep apnea; side effects from taking certain medications, such as antidepressants or beta blockers; or possibly the effects of eating late at night or the makeup of gut bacteria. Recent or excessive weight gain warrants a visit to a doctor to help pinpoint the issue.
A nasal spray containing the experimental drug etripamil can quickly treat an abnormally fast heart rhythm called supraventricular tachycardia. The disordered rhythm occurs sporadically and can raise heart rate to as much as 200 beats per minute.
Alternating toe taps are a good way to strengthen the core muscles without putting extra strain on the lower back.
Excessive drinking can contribute to high blood pressure, obesity, and stroke, while moderate drinking (no more than one drink per day for women and two drinks or fewer per day for men) is linked to a lower risk of heart problems. One possible mechanism might be stress reduction. Brain scans of people who reported light to moderate drinking show less activity in the part of the brain that responds to stress, compared with the scans of people who abstained or drank very little. Stress not only raises blood pressure and heart rate but also triggers inflammation that causes plaque buildup, which contributes to heart attacks.
A polygenic risk score for heart disease is based on an analysis of more than three million common DNA variants and is expressed as a percentile. People can have zero, one, or two copies of any variant, each of which may either raise or lower the risk of coronary artery disease. Many of these variants occur in genes known to affect heart disease, such as those related to cholesterol, blood pressure, and blood clotting. Others aren’t well understood and may provide targets for future research, potentially fueling new drug discovery efforts. For now, the potential benefits of this test are greatest for people under 50.
Older people who take low-dose aspirin every day may be more likely to develop anemia. Aspirin discourages blood clots, but the drug also blocks substances that help maintain and protect the delicate tissue lining the gastrointestinal tract. Long-term aspirin use can damage this protective layer, making bleeding more likely. Minor bleeding can go unrecognized and contribute to anemia, a condition marked by a reduced number of healthy red blood cells. People currently taking aspirin should check with their doctor to see if the practice still makes sense for them.
Tai chi is a gentle, adaptable practice that features flowing movements combined with breathing and cognitive focus. It may be especially helpful for people who are recovering from a heart attack or other medical problems or who have heart failure. Tai chi also can be a gateway to other types of physical activity because the practice may improve balance, reduce the risk of falls, and even help ease lower back pain—a common reason for avoiding exercise.
