The start of a new year is always a great opportunity for people to re-engage with their health. One of the first steps is to conduct a personal health review. It's a way to measure where a person's health stands now, outline the goals, and create a strategy to reach them. A personal health review follows a three-step process: gathering all current health information, listing short- and long-term goals, and sharing everything with a doctor during a scheduled wellness visit.

Walk with a Doc is a nonprofit program founded by a cardiologist that sponsors free, doctor-led walks in mostly outdoor venues (usually public parks) in 560 sites across America. The walks last 30 to 90 minutes, are usually held once per month, and include a five-minute talk about various health topics by the physician. In addition to the exercise and education, participants benefit from the camaraderie and time spent in nature.

A large waistline - 35 inches or more in women or 40 inches or more in men - can signal the presence of visceral fat. Located deep within the abdominal cavity, visceral fat pads the space around the organs and is closely linked to cardiovascular problems. Getting regular exercise (both aerobic and strength-based) and following a healthy, reduced-carbohydrate diet can help reduce visceral fat. Time-restricted eating may also help.

An estimated 3% of adults ages 65 and older currently have dementia, and that proportion rises substantially as people age. The most convincing evidence for reducing one's risk relates to the basic foundations for an overall healthy lifestyle: aerobic exercise, a plant-based diet, and quality sleep. Aerobic exercise helps reduce the buildup of toxic proteins in the brain and improves blood flow, a plant-based diet can manage inflammation, and quality sleep helps the brain clear out harmful proteins.

In a 2023 study, people who did bouts of daily activities, such as taking stairs, mopping the floor, and gardening, that lasted from one to 10 minutes had a lower risk for heart attacks and strokes compared with those who were active for less than a minute.

A 2023 study suggests that people who average 10 or more hours sitting each day face higher risks of dementia than those who sit less, and those risks persist even if they exercise.
