A 2025 study suggests that even a single session of resistance training or high-intensity interval training increases levels of certain proteins that can inhibit breast cancer cell growth, potentially contributing to a lower risk of recurrence.
Arthritis in the joint at the base of thumb (the carpometacarpal joint) can cause pain, weakness, and instability. It can seriously impair the ability to function. Thumb arthritis is diagnosed with a physical examination and x-rays. It can be managed with occupational therapy, which includes learning optimal hand positions and exercises and wearing a hand splint. Pain relief options include heat, pain medications, and cortisone injections. If these are inadequate or the condition is severe, surgery is an option.
A diet high in ultra-processed foods is linked to higher burden of fatty plaque in the carotid arteries, according to a 2025 study.
A free online tool that estimates your heart’s age suggests that most adults have a heart that is older than their chronological age, according to a 2025 study.
A 2025 study finds that smoking and high blood pressure are the two most important factors driving heart disease risk. Together with high cholesterol, excess weight (or being underweight), and diabetes, these five factors account for about 50% of the burden of cardiovascular disease. Compared to people with all five risk factors at age 50, those who had none of the factors were far less likely to develop cardiovascular disease or die early. On average, women with none of the risks at midlife lived 13 more years without heart disease, while men lived an additional 11 years.
Circadian rhythms, which are hardwired into nearly every cell of the body, regulate the heart and blood vessels. Disruptions to this rhythm—from shift work, poor sleep, or unhealthy habits—can raise the risk of cardiovascular disease. For example, heart attacks are more likely to occur on Mondays than any other day of the week. That’s because people tend to stay up later than usual and then sleep in the next day. On Monday morning, when they have to wake up early again for work, the change may cause subtle changes in blood pressure, hormone secretion, and metabolism that raise heart attack risk.
Exercise is one of the most powerful tools for preventing heart disease and extending life. Physical activity triggers favorable changes such as making cells more sensitive to insulin and reducing inflammation. It also helps keep blood vessels supple and flexible (which supports efficient blood flow), strengthens muscles (which helps burn more calories), and remodels the heart, making it more efficient at pumping blood through the body. Together, these changes all reduce a person’s chances of developing common risk factors for heart disease, including diabetes, high blood pressure, high cholesterol, and obesity.
A diet low in sodium and rich in plant-based foods promotes a diverse, balanced population of gut microbes, which may help people maintain a healthy blood pressure. A salty diet increases the prevalence of bad microbes and reduces the number of beneficial microbes. When bad microbes accumulate in the gut, they form breakdown products and toxins that promote inflammation. Beneficial microbes feed on fiber, which is why a diet that provides a mix of healthy fiber from plant-based foods helps. These microbes produce short-chain fatty acids, which interact with specific receptors on cells that help regulate blood pressure.
People who are hospitalized and stay in an intensive care unit have a high risk for home falls and injuries after being discharged, according to a 2025 study. Implementing physical therapy and increasing patient awareness about medication side effects may help.
A 2025 study found that eating large amounts of saturated fat raised LDL (“bad”) cholesterol levels in the body but dietary cholesterol from eggs did not.
