Abstract

Physical exercise is an integral part of a healthy lifestyle. In order to live a healthy lifestyle one must emphasize on not just eating a balanced diet, but also on physical exercise. Physical exercise of any sort, from cardiovascular exerciseto running, jogging, swimming, lifting weights or even dancing may help improve the quality of one's life. Not only it has physical and mental health benefits, research shows that physical exercise might actually be able to reverse the process of aging itself. Physical activity is referred to such an activity which involves movement of muscles. It uses body's own energy to burn calories that produce heat and sweat. Physical exercise in turn increases blood flow of the body. It also produces potent vasodilators, including nitric oxide that further expands blood vessels. Oxygen rich blood is then carried easily to various parts of the body where it was hard to reach before. Cardiovascular exercise is now clinically proven to make the heart strong and for its longevity doctors prescribe a minimum of forty minute session per day. Physical exercise decreases the risk of heart attack, lowers blood pressure and eliminates bad cholesterol from the body. Due to the physical stress and movement, muscles and bones of the body are strengthened. Repeated wear and tear of muscles and bones hence provide an opportunity for them to grow. With proper nutrition and care physical exercise also helps in bodybuilding, along with the loss of excessive fat from the body. Physical exercise has also shown increase in glucose uptake by muscles, thus improving insulin sensitivity and greatly reducing the risk of diabetes. One of the most benecial side effects of physical exercise is weight loss, whereas inactivity or lack of exercise leads towards weight gain and obesity. Being overweight and obese is detrimental towards one's life and forms the basis of various underlying medical conditions. Not only does it make one look good, physical exercise makes one feel good too. It is clinically proven that daily exercise, produces dopamine and endorphins that elevates ones mood. The feel good factor that follows a good exercise session is contributed by changes in levels of hormones produced in the body. The changes in levels of serotonin, melatonin and cortisol all play an important role in wellbeing of one's mental state. One feels relaxed and it remarkably improves the quality of sleep as well. Physical exercise helps one gain focus and block negative thoughts and worries. It helps in fighting against anxiety and chronic depression. It also helps in personality development by boosting one's own self confidence and self-esteem. In order to achieve a healthy lifestyle one must incorporate physical exercise on a daily basis. Moreover one cannot ignore the healthy benefits that accompany physical exercise. In conclusion an hour of physical exercise daily can add years to one's life.
