I wonder how your child's athletic ability is? In addition to symptoms, it is generally diet, staying up late and stress. No matter what sports children can do, it will be useful if all three are taken care of.

Eat less heavy oil fume and snacks. If you want to eat less, look at the calories of snacks to estimate how much you can eat.

If the child's athletic ability is not so good, let him run. Don't choose jogging with several groups of simple running every day. If you have difficulty running fast, let him jump with his legs or jump in place. Then rest between 4 and 5 groups 10 to 30 seconds before you get tired.
