The dangers of taking a cold shower after exercise

Nowadays, more and more people like sports. Many gyms have many people doing sports, which has also attracted everyone's attention because many equipments are not available in our daily life. We must go to the gym to exercise better. Many people, especially male friends, will sweat a lot after exercise, and our metabolism will be very healthy. Do you know the harm of taking a cold shower after exercise?

It is not advisable to take a shower after exercise: Usually, many people like to take a hot (cold) shower immediately after exercise, thinking that this can both remove dirt and restore fatigue. In fact, this is not the case. After exercise, the body has not yet returned to normal, so it is not advisable to take a bath immediately, especially a hot bath. According to research by sports medicine experts, when people exercise, the blood flow to the muscles increases and the heart rate speeds up. When exercise stops, blood flow and heart rate will ease, but they will still last for a long time. If you take a shower immediately at this time, the blood flow to the skin and muscles will increase.

This means that the remaining blood is insufficient to supply other vital organs, such as the heart and brain, which can induce heart disease. Some people take a hot bath immediately after exercise, and often feel dizzy, weak and other discomforts afterwards. This is the reason mentioned above. Especially for the elderly or obese people, they should not take a hot bath immediately after exercise.

After sweating during exercise in the summer, you cannot take a cold shower immediately because the temperature is high in the summer and the body's heat production increases during exercise. The evaporation of sweat and the dilation of skin blood vessels are important ways for the body to dissipate heat. Right after exercise, the human body is still in a state of vigorous metabolism, increased heat production, and dilated skin blood vessels. If you take a cold shower immediately at this time, the skin will be stimulated by the cold water, which will cause skin blood vessels to contract through nerve reflexes. As a result, sweating and heat dissipation will be hindered, making heat dissipation difficult and body temperature rising.

At the same time, the decrease in skin blood flow causes a sudden increase in the amount of blood returning to the heart, which increases the burden on the heart. In addition, when the body suddenly enters a cold environment from a hot environment, it does not have time to adapt and is often prone to catching a cold or causing gastrointestinal cramps. After exercise, muscles become fatigued and tense, and if they are exposed to cold stimulation at this time, they may cause cramps. After sweating during summer exercise, you should drink some salt water, then rest for about an hour, do some warm-up exercises and then take a cold shower. If conditions permit, it is best to take a warm bath.

Many people like to take a cold shower immediately after exercise, which can quickly lower their body temperature and cool their bodies. However, taking a cold shower after exercise is not allowed. We have all seen the above hazards, so try not to take cold showers in the future and use warm water instead. This is the only way to ensure our health.
