Regular physical activity can help you lose excess weight; improve physical fitness; lower many heart disease risk factors such as “bad” LDL cholesterol levels, increase “good” HDL cholesterol levels, and manage high blood pressure; lower stress and improve your mental health; and lower your risk for other conditions such as type 2 diabetes, depression, and cancer. Even modest amounts of physical activity are good for your health.

Sleep plays a vital role in good health and well-being throughout your life. The way you feel while you are awake depends in part on what happens while you are sleeping. During sleep, your body is working to support healthy brain function and maintain your physical health. In children and teens, sleep also helps support growth and development. Getting inadequate sleep over time can raise your risk for chronic health problems. It can also affect how well you think, react, work, learn, and get along with others. Learn how sleep affects your heart and circulatory system, metabolism, respiratory system, and immune system and how much sleep is enough.
