Why wash your hands immediately after fitness exercise?

Sweat, grease, dander, etc. It will be produced on the hands after fitness exercise. These sticky substances such as sweat, grease and dander will stick to dust, bacteria, fungi and viruses. Therefore, you should wash your hands immediately and wash away the dust, sweat, grease, dander, bacteria, fungi, viruses and other harmful substances on your hands to avoid hydration, nutrition and pollution and human infection when washing your hands after exercise. There is no need to wash them. You should use soap and other washing water. If there is warm water, it is best to wash it with warm water, so as to avoid blood flow obstruction caused by vasoconstriction, resulting in a large number of metabolites produced after the human body moves away and stays, and new oxygen and nutrients cannot flow in, causing physical discomfort and even causing symptoms such as colds and infections. I wish my friends a happy fitness! Healthy life!
