Write briefly, what is the role of physical activities in improving the quality of life.

Without regular physical activity, the body slowly loses its strength, stamina and ability to function well. And for each hour of regular exercise you get, you’ll gain about two hours of additional life expectancy, even if you don’t start until middle age. Moderate exercise, such as brisk walking, for as little as 30 minutes a day has the proven physical health benefits listed above as well as:

• Improves blood circulation, which reduces the risk of heart disease
• Keeps weight under control
• Helps in the battle to quit smoking
• Prevents bone loss
• Boosts energy level
• Helps manage stress
• Helps you fall asleep faster and sleep more soundly
• Increases muscle strength, increasing the ability to do other physical activities
