The Best Time and Water Temperature to Shower After Exercise Are Really Important
Many people take a bath immediately after exercising, which is a very bad habit. Let's take a look at the adverse effects on health.
Post-exercise hot bath
According to research by sports medicine experts, when exercising, more blood flows to the muscles, and the exercise heart rate increases. After exercise stops, although the blood flow and heart rate have eased, they still persist for a relatively long time. If you immediately take a bath, it will increase the blood flow to the skin and muscles. This will lead to insufficient blood supply for other important organs, such as the heart and brain, thereby inducing cardiovascular disease.
Some people take a hot bath immediately after exercising, and they often feel dizzy, lightheaded, and weak. This is due to the above reasons. In particular, the elderly or obese people should not take a bath immediately after exercise.
Cool water bath after exercise
Exercising and sweating immediately wash with cold water, which is also harmful. During exercise, the body temperature increases through sweating and skin blood vessel dilation, accelerating heat dissipation. Just after finishing exercise, the body's metabolism is vigorous and heat production increases. When the skin blood vessels are dilated, if you immediately take a cold shower, the skin will be stimulated by cold water, causing vasoconstriction through nerve reflexes, which can hinder heat dissipation and increase body temperature. At the same time, the blood volume in the skin decreases, and the cardiac output increases, placing a great burden on the heart.
In addition, suddenly transitioning from a hot environment to a cold environment, without adapting, often leads to a cold or causes gastrointestinal spasms. After exercise, muscles are fatigued and tense, and if they are further stimulated by cold, it may trigger convulsions.
Correct practice
Bath time:Wait until the body temperature and heart rate gradually return to normal, about 20-30 minutes. During this period, give the body sufficient hydration. Bath time should not be too long, and just rinse it off.
Water temperature: Close to body temperature is appropriate, to avoid the above-mentioned two adverse effects on health.
