The importance of staying active
In addition to eating high-quality foods, physical activity can help you reach and maintain a healthy weight.
- Getting regular physical activity is one of the best things you can do for your health. It lowers the risk of heart disease, diabetes, stroke, high blood pressure, osteoporosis, and certain cancers, and it can also help control stress, improve sleep, boost mood, keep weight in check, and reduce the risk of falling and improve cognitive function in older adults.
- It doesn’t take marathon training to see real health gains. A 30-minute brisk walk on five days of the week is all most people need. Getting any amount of exercise is better than none.
- Being a “couch potato” may be harmful even for people who get regular exercise.
- The precise amount of exercise needed to achieve or maintain a healthy weight varies based on a person’s diet and genes. The American College of Sports Medicine and the American Heart Association support the idea that “more activity increases the probability of success”.
More recently, studies have found that people who spend more time each day watching television, sitting, or riding in cars have a greater chance of dying early than people who are more active. Researchers speculate that sitting for many hours may change peoples’ metabolism in ways that promote obesity, heart disease, diabetes, and other chronic conditions. It is also possible that sitting is a marker for a broader sedentary lifestyle. Furthermore, staying active does not mitigate the harmful effects of sit time. As you plan your daily activity routine, remember that cutting down on “sit time” may be just as important as increasing “fit time.”
