When a shoulder workout seems time-consuming or challenging, it might help to make the exercises easier or more appealing. One approach is doing shoulder exercises with a resistance band instead of fancy weight machines. Another strategy is doing a few occasional shoulder exercises, such as making arm circles, while seated. And it might be fun to dance and move the arms in time to music, which works the shoulder muscles; or to place a ball against a wall and roll the ball in small letter shapes from A to Z, which works all of the muscles in the shoulders.

People who climb more than five flights of stairs—about 50 steps—daily may lower their risk of cardiovascular disease, according to a 2023 study.

Avoiding germs that cause respiratory and gastrointestinal illnesses is especially important during the winter months, when cases are on the rise. Learn which strategies keep you safe. 

Scientists are trying to create a vaccine that would protect people against all different strains of the influenza (flu) virus. These vaccines are being designed to target parts of the flu virus that don’t change regularly and so are consistent across all strains. The perfect vaccine would also prevent symptoms (since current vaccines help prevent hospitalization and death, but not symptoms), and its effects would last for a lifetime. While such a vaccine is still many years away from reality, improved flu vaccines are expected in the meantime.

Palliative care for heart failure aims to improve quality of life for patients and their families by addressing physical symptoms, and also emotional, psychosocial, and spiritual issues. This may include treating anxiety and depression in patients and supporting caregivers, who may be dealing with stress and worry. Palliative care also includes talking with patients about their personal goals and what matters most to them, which can help guide their care as the illness progresses.

For people with chronic coronary disease who do not have symptoms, new guidelines recommend against routine testing with cardiac CT angiography, echocardiography, and stress testing. The results are unhelpful—and in some cases harmful. Unclear results often general additional testing or unnecessary procedures, including some that expose people to radiation for no reason. In addition, the tests add expense without any corresponding benefit, and these costs are increasingly being passed back to patients, in the form of copayments or higher premiums.

Planks are an isometric exercise, in which the muscles contract but do not move. They are a great way to strengthen muscles in the abdomen, back, legs, shoulders, and arms.

Ejection fraction is the fraction (expressed as a percentage) of the blood that the heart “ejects” out to the rest of the body when it contracts. Low ejection fraction signals one form of heart failure. An echocardiogram is the standard test to measure ejection fraction.

Despite statements like “promotes heart health” on the labels of fish oil supplements, multiple randomized trials show no evidence of heart-related benefits from using these products. In addition, manufacturing methods might make the products either useless or even harmful. The supplements do provide omega-3 fatty acids, but people can get these essential fats by eating two servings of fatty fish weekly or following a vegetarian diet rich in healthy oils, nuts, and seeds.

Products that encourage healthy eating or exercise can make good holiday gifts for family and friends. Examples include cooking gadgets (such as a food chopper or high-quality knife), a gift basket of fresh fruit or Mediterranean-inspired treats, or home workout equipment (such as dumbbells, resistance bands, or sports-related gear).
