Does Exercise Really Keep Us Healthy?
Physical fitness is essential to good health and is one of the best things you can do for your body, mind, and spirit. Exercise improves the way your body works, and it can make you look better, feel better and even live longer, and look younger.
Moderate exercise, such as walking, can reduce the risk of diabetes in obese and sedentary people whose blood sugar is starting to rise. Active people are much less likely to smoke; they’re thinner and they eat differently than their sedentary peers. They also tend to be more educated, and education is one of the strongest predictors of good health in general and a longer life. Reducing your weight by just 10 pounds may be enough to lower your blood pressure. Losing weight can help to enhance the effects of high blood pressure medication and may also reduce other risk factors, such as diabetes and high bad cholesterol.
Physical activity contributes to health by reducing the heart rate, decreasing the risk for cardiovascular disease, and reducing the amount of bone loss that is associated with age and osteoporosis. Physical activity also helps the body use calories more efficiently, thereby helping in weight loss and maintenance. It can increase basal metabolic rate, reduces appetite, and helps in the reduction of body fat.
