Thick clothes will hinder people's heat dissipation, and the human body will excrete more sweat to increase the heat dissipation effect. If you sweat more, you will naturally lose weight, but it will not improve the weight loss effect, because the calories consumed are basically unchanged and the water is lost. Therefore, the so-called purpose of skipping running in down jacket is to accelerate dehydration and some salt. If you don't do this, the effect of dehydration and desalination will definitely decline.

Matters needing attention in sports

Attention should be paid to the middle-aged and elderly sports people in parks and squares, who lack sports knowledge. Few people will warm up before exercise and relax their muscles after exercise, which is very harmful to their health. Despite the high temperature in summer, it is still necessary to carry out short-term low-intensity warm-up exercises to move all joints of the body and promote the body to enter the working state.

After strenuous exercise, the body is seriously short of water and needs proper hydration. Don't drink too much water at a time, which will increase the pressure on the stomach, thus increasing the load on the heart and causing harm to the body. The correct way to drink water is to drink a little first, sip half a cup, and don't gulp it. Drink some warm water, and then you can also drink some honey water.
