What are the dangers of strenuous exercise in jogging?

Jogging is a particularly popular form of exercise currently. This form of exercise has indeed benefited many people. Through jogging, many diseases in the body have been eliminated and immunity has been improved. However, strenuous exercise after jogging can cause great harm to the body. Here are the dangers of strenuous exercise after jogging. People who jog regularly can learn about it.

1. You cannot rest immediately. When you do strenuous exercise, your heart rate will speed up, your muscles and capillaries will expand, and blood flow will speed up. At the same time, the rhythmic contraction of muscles will squeeze the small veins, causing the blood to flow back to the heart quickly. If you stop to rest immediately at this time, the rhythmic contraction of the muscles will also stop, and the large amount of blood that originally flowed into the muscles will not be able to flow back to the heart through muscle contraction, causing low blood pressure and temporary cerebral ischemia, leading to symptoms such as palpitations, shortness of breath, dizziness, pale complexion, and even shock and fainting.

2. Do not take a bath immediately. After strenuous exercise, in order to maintain a constant body temperature, the blood vessels on the skin surface expand, the sweat pores open, and perspiration increases to facilitate heat dissipation. At this time, taking a cold bath will cause the blood vessels to contract immediately due to sudden stimulation, and the blood circulation resistance will increase. At the same time, the body's resistance will be reduced, and people will be prone to illness. Taking a hot bath will continue to increase the blood flow in the skin, and too much blood will flow into the muscles and skin, causing insufficient blood supply to the heart and brain. In mild cases, it may cause dizziness, and in severe cases, it may cause collapse and shock, and it may also easily induce other chronic diseases.

3. Do not drink excessively to quench thirst. When you feel thirsty after strenuous exercise, some people drink excessively cold boiled water or other beverages, which will increase the burden on the gastrointestinal tract and dilute the gastric juice. This not only reduces the bactericidal effect of gastric juice, but also hinders the digestion of food. Drinking water too quickly will also cause blood volume to increase too quickly, suddenly increasing the burden on the heart, causing temporary disorders of electrolytes such as potassium and sodium in the body, and even heart failure, chest tightness, abdominal distension, etc.

4. Avoid eating a lot of sugar. Some people feel comfortable eating sweets or sugar water after strenuous exercise, and think that eating more sweets after exercise is good. In fact, eating too much sweets after exercise will cause the body to lose vitamin B.

1. If you consume a lot of energy, you will feel tired, lose your appetite, etc., which will affect your physical recovery. Therefore, after strenuous exercise, it is best to eat more foods containing vitamin B1, such as vegetables, liver, eggs, etc.

5. Do not drink alcohol to relieve fatigue. After strenuous exercise, a person's body functions will be at a high level. Drinking at this time will cause the body to absorb alcohol faster and enter the blood, which will cause greater harm to organs such as the liver and stomach than usual. Doing this for a long time can cause fatty liver, cirrhosis, gastritis, gastric ulcer, dementia and other diseases. Drinking beer after exercise is also not good, as it will increase the uric acid in the blood, greatly irritate the joints and cause inflammation.

Although jogging is a good way to exercise, strenuous exercise after jogging can be harmful to the body, so you should stop slowly after jogging. In addition, you should also pay attention to the diet when jogging, so that you can ensure your body's health through jogging and diet.
