Stress can affect sleep, mood, and appetite, and the long-term effects of chronic stress have been linked to health issues like cardiovascular disease, obesity, and Alzheimer's disease. A wearable device claims that it can reduce stress and build the wearer's resistance to stressful situations — but how does it work, and can any of its claims be proven?

Sometimes the presence of atherosclerosis, the disease underlying most heart attacks, is not clear or easily recognized, especially before a heart attack or other crisis happens. In those instances, doctors may rely on a coronary artery calcium (CAC) scan, which measures the amount of calcium in the heart's arteries, high levels of which are associated with cardiovascular disease. The CAC results can help predict a person's risk for heart attack or stroke, even if that person doesn't have obvious risk factors or symptoms.

Even small amounts of alcohol—a single drink per day—has been linked to a higher risk of developing atrial fibrillation.

Evidence suggests that people who recover from COVID-19 have an increased risk for developing new health problems, including heart attacks, high blood pressure, diabetes, high cholesterol, muscle inflammation, blood clots that travel to the lungs, strokes from clots or hemorrhages, or psychosis. This is in addition to permanent damage that can result from having COVID, including damage to the lungs, heart, kidneys, brain, or other organs; and debilitating fatigue, difficulty thinking, and other symptoms that make it hard to function normally at work or at home.
