If you can only run at night, you can choose to exercise one hour after dinner. Exercising too early will easily lead to the dysfunction of the digestive system, and if you exercise too late, the excitability of the nervous system is too high, which is not conducive to sleep at night, easily causing insomnia, and also prone to hypoglycemia and other adverse consequences.
