Is lunch time suitable for fitness? Professor Wang Anli, doctoral supervisor of sports physiology in Beijing University of Physical Education, said: The first thing to pay attention to when exercising before and after lunch is that you can't exercise after eating, or you can't exercise if you eat too much. Because after eating, blood will flow to the digestive tract. During exercise, blood will flow into the limbs. If you just eat enough exercise, blood will flow back from the digestive tract to the limbs, which will affect digestion and absorption. You can add a little food about half an hour before fitness, without too much. Because after a morning's work, the energy provided by breakfast has been basically consumed by the human body. If you don't eat, it is easy to cause hypoglycemia. Eating for a while after fitness will help restore your body energy as soon as possible and ensure that you have enough work energy in the afternoon.

The time for fitness at noon is relatively short, and there is often not much time for finishing activities, including bathing. After sweating, be sure to change into wet clothes soaked by sweat in time. Because the moisture on cold and wet clothes will evaporate and dissipate heat, the blood vessels of the skin will contract, which will affect the supply of nutrients and easily cause a cold.
