During exercise, the blood flow to the muscles increases and the heart rate increases.

When exercise stops, blood flow and heart rate will be relieved, but it will last for a long time. If you take a bath immediately, it will increase the blood flow to your skin and muscles.

In this way, the remaining blood is not enough to supply other important organs, such as the heart and brain, which will induce heart disease. It is not advisable to take a bath immediately after exercise. It is recommended to rest for 20-30 minutes after exercise, and take a shower with warm water after proper hydration. Don't take too long, the water temperature is close to body temperature. The optimum water temperature is 35-37 degrees. The reasonable bathing time is that the heart rate returns to stability after exercise and after sweating stops.

Other matters needing attention in sports

1, don't eat it right away.

After exercise, there is relatively little blood in the digestive organs, and the digestion and absorption ability is poor. If you eat it immediately, it will increase the burden on the digestive organs and cause dysfunction of the digestive organs. Generally, after 20 to 30 minutes of exercise, the digestion and absorption function will gradually recover.

2. Don't smoke right away.

The air inhaled into the lungs is mixed with a lot of smoke, which will reduce the oxygen content in the lungs, which is not conducive to the elimination of fatigue, and may also cause chest tightness, asthma, dyspnea, dizziness and fatigue.

3. Don't drink coffee right away

Exercise is the best time to recover, and caffeine has a certain diuretic effect, and urination will accelerate the loss of water in the body, so it is not recommended to drink coffee within 1 hour after exercise and fitness.

My basic habit of exercising is after dinner. After exercise, I will walk for a while, relax, then go back to the dormitory, brush my mobile phone and be in a daze. After the sweat evaporates, I will go to my sister's house to take a bath.
