CHN Health Matters
Being physically active is an important way to improve your chances of living longer. Physical activity reduces risk of heart disease by helping to lower blood pressure, blood sugar, weight, and cholesterol. In addition physical activity improves muscle strength, bone strength and balance and therefore decreases chances of falling. Also, physical activity improves mental health and mood.
The CDC advises at least 150 minutes or 2½ hours a week of moderate physical activity or 75 minutes of vigorous activity. An example of moderate activity would be a brisk walk. Moderate activity generally would cause enough trouble breathing that it would be hard to carry on a normal conversation. In addition two days of weight training a week that works all major muscle groups is advised. More intense exercise more often provides even more benefit.
