Battling another cough or cold? You may feel better if you take a daily walk or follow a simple exercise routine a few times a week. Exercise helps decrease your chances of developing heart disease. It also helps keep your bones healthy and strong.
We do not know exactly if or how exercise increases your immunity (免疫) to certain illnesses. There are several theories. Some of these theories are as follows:
Physical activity may help move bacteria (细菌) out of the lungs and airways.
The brief rise in body temperature during and right after exercise may prevent bacteria from growing. This temperature rise may help the body fight against infection (传染) better.
Some stress increases the chance of illness. Lower stress hormones(荷尔蒙)may protect against illnesses.
Exercise is good for you. Studies have shown that people who follow a moderately (适度地) energetic lifestyle, benefit most from starting and sticking to an exercise program. So go ahead, take an aerobics class or go for a walk. You will feel better and healthier for it.
A. Feeling tired all the time?
B. Have you taken a walk today?
C. However, you should not overdo it.
D. However, none of them have been proven.
E. Exercise slows down the release of stress hormones.
F. People should not exercise more just to increase immunity.
G. This may reduce your chance of getting a cold or other illnesses.
