Exercise caution against "storm of sympathy"

The warm weather is a good time for fitness. But do you know? If it is over-exercise, it can easily lead to “storm of sympathy” and cause a tragedy.

We know that the rhythmical beating of the heart is mediated by sympathetic and parasympathetic nerves. Parasympathetic (vagus) nerve tension increases, heart is inhibited, heart rate slows down, sympathetic nerves are excited, heart is excited, contractility is increased, and heart rate is accelerated. If you are involved in high-intensity sports and training, over-excited sympathetic nerves can cause the heart to be highly excited. It is like a storm and it is called a "storm of sympathy." If the heart is highly excited, tachycardia can reach up to 200 times per minute and there is a risk of ventricular fibrillation. In addition, serious anoxia, electrolyte imbalance and acid-base balance, perioperative traumatic operations, drug poisoning, extreme anger, fear, grief, despair, etc., may all lead to “storm of sympathy”.

From this we can see that when participating in physical exercise, we must do what we can and use the principle of “moderation”. If you feel uncomfortable during exercise, you must stop exercising in time. Do not be stubborn. In the event of a "storm of sympathy," immediate treatment should be carried out to save the patient's life. (Yang Feng)
