Don't drink tea immediately after exercise, especially strenuous exercise, especially strong tea. Although tea has a good health care function, drinking tea after exercise is easy to stimulate the stomach and cause physical discomfort, which is not conducive to health.
Don't drink tea immediately after exercise;
First, drinking tea increases the burden on the heart.
At the end of exercise, the heart beats faster and the burden on the heart is heavier. Caffeine contained in tea has an exciting effect. If you drink tea immediately, it will easily increase the burden on your heart and make people feel uncomfortable such as rapid heartbeat and chest tightness.
Second, it leads to water loss.
Caffeine in tea also has certain diuretic and dehydration functions. After exercise, the body will sweat a lot and lose a lot of electrolytes. Drinking tea containing caffeine is more likely to aggravate the loss of body fluids and stimulate the central nervous system, which is not conducive to recovery after exercise.
Third, lead to iron deficiency anemia.
Part of iron in human body will be lost with sweat during exercise, and tea contains tannic acid. After tannic acid enters the body, the iron in the body combines with tannic acid to form precipitation, which leads to the lack of more iron in the body, thus forming iron deficiency anemia.
Extended information exercise diet note:
1. First, eat a small amount of food before exercise. "It is very bad for human health to start exercising on an empty stomach and just after eating." Chongqing nutrition and sports experts said that eating a small amount of food half an hour before exercise can avoid digestive disorders caused by physical activity and enhance the exercise effect. If it is morning exercise, you must avoid indigestible food for breakfast, and it is best to eat a small amount of dairy products, cereals, fruits and drinks.
2. Secondly, we should replenish water in time during exercise. Chongqing nutrition and sports experts say that if the exercise time is less than 1 hour, drink 150 ml to 300 ml of water every15 minutes; If the exercise time is 1 to 3 hours, you should replenish sugar water to your body in time to avoid hypoglycemia. In addition, don't drink ice water during exercise, because drinking ice water during strenuous exercise will cause digestive system problems; Also, don't drink water immediately after strenuous exercise, because after exercise, the metabolism of the human body is accelerated and sweat is discharged. Drinking water immediately will accelerate the loss of inorganic salts in the body, so take a break before drinking normal temperature water and light salt water.
3. Exercise consumes minerals such as calcium and magnesium in the body. At the same time, calcium and magnesium supplementation will increase the burden on the stomach and easily lead to bad stomach. Drinking soft water is relatively better, but the same mineral composition will be less. Therefore, if you use soft water to replenish water during exercise, you'd better eat some foods containing salt and minerals at the same time. Hard water is more suitable for supplementing mineral components such as calcium and magnesium after exercise. Because it is easy to increase the burden on the stomach and intestines, you can take a few times after exercise. Drinking hard water can also prevent leg cramps and muscle spasms during exercise.
Finally, it is not advisable to eat acidic food such as fish after exercise. Chongqing nutrition and sports experts said that after exercise, sugar, fat and protein in the human body are decomposed in large quantities in the absence of endogenous oxygen, resulting in acidic substances such as lactic acid and phosphoric acid, which will stimulate human tissues and organs and make people feel sore muscles and joints and mental fatigue. Fish and other foods are acidic foods. Eating these acidic foods after exercise will make body fluids more acidic, which is not conducive to the relief of muscle and joint pain and physical fatigue. Experts suggest that you should eat more alkaline foods such as fruits, vegetables and bean products after exercise to maintain the acid-base balance in the human body, thus eliminating exercise fatigue and keeping healthy.
