In fact, the human body has its own ability and system to regulate temperature. When sweating heavily in summer, you must not directly wipe your body with a cold towel or take a cold bath, because direct action on the skin will lead to unreasonable heat dissipation process on the body surface, leading to the accumulation of deficiency heat in the body, which is harmful to your body. In addition, directly wiping the body with a cold towel or taking a bath with cold water will not reduce the skin's ability to regulate temperature!
The self-regulation of human body temperature is mainly realized by sweat discharged from pores. At high temperature, the human body produces more heat, and sweat glands secrete a lot of sweat and attach to the skin surface. When sweat changes from liquid to gas, it will take away a lot of heat from the human body, thus playing the role of scientific cooling. According to the survey, every evaporation of 1 ml of sweat can take away 0.58 kcal of heat. Therefore, if you wipe it off immediately after sweating, you can't play its role of evaporation and heat dissipation; At the same time, because the heat can't be emitted, sweat glands will keep secreting sweat, so that the organic matter and salt in our body will disappear with sweat!
The best way to warm up in summer is to use a warm towel or take a warm bath, which is more conducive to the elimination of heat. Because the skin is stimulated by cold, the pores will close, the capillaries will contract, and the accumulated heat in the body will not be emitted. At this time, the human body will feel irritable. If we use warm water, the skin surface is stimulated by heat, which can help our pores expand rapidly and then let the heat dissipate faster!
Therefore, when sweating in summer, instead of choosing a cold towel or a cold water bath, it is better to take a hearty hot bath or scrub your body with warm water, which can help us cool down quickly and healthily. At the same time, we should remind friends, especially female friends, to avoid touching cold things in summer. Although it can quickly cool down and get a temporary coolness, it is extremely harmful to the human body!
