Women are disproportionately affected by conditions that cause chronic pain, but they sometimes have difficulty getting a definitive diagnosis as to what is causing their pain and may be less likely to receive appropriate treatments even when they do.

A 2023 Harvard study found that regularly squeezing a week's worth of exercise (150 minutes) into just one or two days—a "weekend warrior" approach—is linked to the same heart-healthy benefits as daily exercise.

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 2023 study suggests eating enough of six categories of food common in popular heart-health diets is associated with a lower risk of cardiovascular disease, including heart attacks and strokes. The six groups are fruits, vegetables, legumes, nuts, fish, and dairy products.

A 2023 study suggests taking testosterone replacement therapy does not raise the risk for heart attacks or stroke among men with cardiovascular disease or a high risk for it, but it could increase the risk of atrial fibrillation, acute kidney injury, and pulmonary embolism.

People who devote time to helping others are often happier than those who don't. Serving others also helps brain health by increasing social connections, which can protect against loneliness and depression, and improving executive function skills like planning, attention, and remembering tasks. Common ways to help others include volunteering, mentoring, random acts of kindness, and seeing life from another person's perspective.

Lower temperatures, high wind speed, atmospheric pressure, high precipitation, and high degrees of pollution may raise the risk of being hospitalized for serious heart-related conditions. Modeling these factors may help forecast future heart problems.

Memory loss is a pervasive worry. Dementia will affect an estimated nine million Americans by 2030 and 12 million by 2040. A 2023 study suggests six healthy lifestyle factors can significantly slow memory decline: eating a healthy diet, exercising regularly, not smoking, not drinking alcohol, being socially active, and engaging in brain-challenging activities. Another 2023 study suggests regular Internet use may be linked to a lower risk of dementia.
