Exercise Is Not Only To Lose Weight
Exercise is good for the mind and for the body. It sharpens the mind and boosts mood. It provides energy and a sense of mastery. It improves the quality of your sleep so you wake up feeling better rested. It keeps the heart and blood vessels in working order. It protects against such common conditions as diabetes. It is invaluable in weight control.
Now comes more good news: Intense exercise may curb your sweet tooth. Animal studies show that exercise decreases preference for sweetness. Scientists aren’t sure why exercise has this effect. It may be that intense activity revs up endorphins and related substances in your brain, and that powerfully positive blast of pleasure might decrease the need for satisfying food.
The danger for athletes is that such an effect might keep them from consuming enough food to replace calories lost in exertion. But most of us have no such problem. And there's more good news... Long-term exercise improves your immune system with 30 minutes of exercise a day. Three times a week, adults strengthened not only their muscles but the immune system’s first line of defense against viral infection. Blood tests showed them to have more active natural killer cells.
They had no such boost in immune function if they exercised for only three months. It took 11 months of working out to impact the immune system. The results were especially important because the exercisers were older adults. The researchers say the study demonstrates how a little exercise can help people maintain their health and independence with advancing age.
As the saying goes, use it or lose it. When you stop exercising, you lose not only the physical benefits, but the psychological benefits as well.
