7.Do you know why you need to take exercise to keep fit?The following may help you know about it.
•It helps with addiction(癖嗜)control
The brain releases dopamine(多巴胺),which responds to any form of pleasure,be it sex,drugs,alcohol or food.Some people become addicted to dopamine and substances that produce it-especially drugs or alcohol.
Regular exercise can help in this addiction recovery as it effectively distracts you,making you de-prioritize your cravings.When faced with mental or emotional challenges in life,exercise can help you cope in a healthy way instead of resorting to alcohol,drugs or other negative behaviors that eventually only make your symptoms worse.Regular exercise can also help to strengthen your immune system.
※Your risk of diabetes(糖尿病)goes down
Within one week of your regular exercise,your sensitivity to insulin (胰島素)becomes greater and that,in turn,lowers your blood sugar levels,reducing your risk of Type 2 diabetes.
Also,exercise can decrease your stroke(中風(fēng)) risk; given that two of the greatest risk factors for strokes are high blood pressure and heart disease,exercise with its benefits of a stronger heart and better circulation is important.
The U.S.Centers for Disease Control and Prevention recommends at least 30 minutes of moderate exercise at least five days a week for good health,though you should always check with your doctor if you have any health concerns before beginning any exercise program.
※You're reducing stomach fat
When you do one month of regular exercise,your body ditches those extra fat and gains muscle.An Australian study shows that overweight people who took part in a four-week program of moderate exercise reduced stomach fat by 12 percent.
