Why is Exercise Good for Your Health?
The most obvious reason why exercise is good for your health might be its role in helping you keep from gaining weight, or at least losing it if you have become overweight. When you exercise, you burn calories. If you burn the same number of calories that you take in through food each day, you will likely maintain your weight. Likewise, if you take in more calories than you burn, you will likely gain weight, and if you burn more than you take in, you will likely lose weight. Children often experience one acceptable exception to this rule: Since they are still growing, they will gain weight simply through an increase in bone and muscle mass, and will not become “overweight” because of this.
Another benefit of exercise is strengthening your muscles. You must use your muscles - all of them - in order to be strong. If you just sit around and don’t do anything physical, your muscles will become weak. Perhaps you have heard that this is true about your heart muscle. You need to exercise and make your heart beat hard and fast in order for it to be strong.
A third reason for exercising is to make the pituitary gland in your brain secrete hormone molecules called “endorphins.” Endorphins are what give you a really good feeling after you have exercised.
Finally, exercise burns another hormone called “cortisol.” Cortisol is what is known as the stress hormone. When you feel angry, anxious, or fearful, cortisol is produced by your body and can eventually inflame and damage your internal organs if it is produced frequently. Since exercise burns cortisol, it can help prevent the damage caused by stress.
Remember that God created you with the intention that you would trust Him. If you trust Him, and believe that He created you for a good purpose, you will want to have good health and be free of the harmful effects of stress. So, get regular exercise!
