What causes nausea after exercise?

Fitness exercise is a form of exercise that many people like, but everything has its pros and cons. Sometimes some discomfort symptoms will appear after exercise. The most common one is that many people will feel nauseous and even vomit. The reason for this is mostly because you usually exercise too intensely, and you don’t get enough rest during the exercise, so your body can’t bear it.

Many people know that some simple warm-up activities should be performed before fitness exercises to get the body into the exercise state. However, many people often sit down to rest or bend over to catch their breath immediately after strenuous exercise, which is actually very harmful to the body.

When people exercise vigorously, the heart is in a high-efficiency working state. The heart will transport a large amount of blood to the muscles of the upper and lower limbs in a short period of time. If the strenuous exercise stops suddenly, the heart will still output a large amount of blood, but the blood flowing back to the heart is greatly reduced. At this time, not only does the brain not get enough blood replenishment, but under the action of gravity, the original brain blood will be rapidly replenished back to the heart, causing temporary anemia in the brain, blacking out, dizziness, nausea, vomiting and even fainting. This is called "gravity shock" during exercise. In addition, a large amount of lactic acid will be produced in the body during exercise. If you stop exercising suddenly, it will not be conducive to the decomposition and elimination of lactic acid. The exerciser will feel sore all over and his muscles will become stiff.

Smart fitness enthusiasts should add an "epilogue" to their exercise and do some relaxation exercises after the exercise. First, you should slow down and exercise at a lower intensity for a few minutes. For example, when running, the normal speed is 13 km/h. Before the end of the exercise, you can brisk walk at a speed of 5 km/h for 5 minutes, and you can also shake your limbs and walk back and forth. Secondly, do stretching exercises for about 10 minutes, holding each movement for 15-30 seconds. Finally, soaking in warm water at 30-40 degrees after exercise can have a calming effect on the nervous system and accelerate the elimination of fatigue.

In short, exercise can indeed help with fitness, but everything requires mastering the method and the right amount to ensure that the body will not be harmed. In addition, it is recommended that you should exercise regularly. Before exercising, you should also pay attention to warming up before officially starting. This can also prevent physical discomfort after exercise.
