Exercise - Advantages and disadvantages

We are living in the new era of modern technology which helps us handle most of our manual works. As the matter of fact, some hold the view that people not only have to train their mind to deal with works but also need to exercise to maintain a good health. On the contrary, some others argue that too much exercise also damages your health. Every coin has their two sides, honestly, I believe there are both pros can cons in this issue.
On the one side, nobosy can deny the fact that exercise regularly and moderately bebefits us a lot. First, Exercise controls weight. Exercise can help prevent excess weight gain or help maintain weight loss. When you engage in physical activity, you burn calories. The more intense the activity, the more calories you burn. People involved in exercise always have fit and slim bodies. Second, Exercise improves mood. Physical activity stimulates various brain chemicals that may leave you feeling happier and more relaxed. You may also feel better about your appearance and yourself when you exercise regularly, which can boost your confidence and improve your self-esteem. Third, Exercise boosts energy. Regular physical activity can improve your muscle strength and boost your endurance. Exercise and physical activity deliver oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently. Last but not least, Exercise combats bad health conditions and diseases. No matter what your current weight, being active boosts high-density lipoprotein (HDL), or bad cholesterol and decreases unhealthy triglycerides. Exercise keeps your blood flowing smoothly, which decreases your risk of cardiovascular diseases. In fact, regular physical activity can help you prevent or manage a wide range of health problems and concerns, including stroke, metabolic syndrome, type 2 diabetes, depression, certain types of cancer, arthritis and falls.
On the other side, the supporters of the idea that exercising also has its drawbacks are right to some extent. First of all, Too much exercise can be harmful. Without proper rest, the chance of stroke or other circulation problems increases, and muscle tissue may develop slowly. Extremely intense, long-term cardiovascular exercise, as can be seen in athletes, who train for multiple marathons, has been associated with scarring of the heart and heart rhythm abnormalities. Secondly, irregular exercise is also a popular problem. Many young people involve in exercise just to lose weigh and get a sexy body instead of getting a good health. With a short-term and unclear goal, they easily geat bored and do exercising irregularly of maybe quit it. Stopping excessive exercise suddenly can also create a change in mood. Feelings of depression and agitation can occur when withdrawal from the natural endorphins produced by exercise occurs. Moreover, after a long time, when they begin to exercise again, if they somehow work out too much, it also causes to some heart problems as well. Finally, vitamins, minerals and iron loss during execise is an unseen threat for health. Great evidences show that people may lose some vitamin and iron after taking exercise. It results in vitamin and iron loss through a variety of mechanisms. Some iron, as well as vitamin E is lost in sweat, and, for unknown reasons, intense endurance exercise is sometimes associated with bleeding of the digestive system which causes a great amount of loss. As vitamin and iron play important roles in our body, the loss of them could cause sick or some serious diseases.
In short, exercise itself is not harmful. It is dangerous or not just base on the way we do it. As an old saying goes, the urge to destroy is also a creative one, so next time when doing exercise, it is better to reconsider how to do it and look for some professional advices.
