In mid-July, the humidity after the rain was accompanied by high temperatures. The hot and humid weather made people hard to breathe. The phone of the 120 dispatch and command center rang. "An adult male fainted at the gate of a primary school." The crew of the Fengtai District Tieying Emergency Station received the task and set off immediately. On the way, they learned that the patient fainted and fell to the ground while waiting to pick up his child at the school gate. It was considered to be a shock caused by heatstroke.

Here are some health tips from Beijing 120. The temperature is getting higher and higher in midsummer, and the rain is frequent. The high temperature and high humidity environment will accelerate the body's oxygen consumption, causing vasodilation and rising the blood flow rate. It may increase the risk of cardiovascular and cerebrovascular emergencies. When people sweating a lot and it is unable to replenish water, it may cause hypoxia, resulting in insufficient oxygen supply to the brain, causing symptoms such as headaches, dizziness, nausea. Some severe cases may show electrolyte disorders. It is recommended to take heatstroke prevention measures when going out, such as wearing sun hats, umbrellas, and timely replenish water to prevent heatstroke. Especially for the elderly with hypertension, diabetes, and cardiovascular or cerebrovascular diseases, once they feel stuffy and uncomfortable, it is necessary to call the 120 emergency center in time or go to the nearest medical institution for diagnosis and treatment. Do not delay the treatment.
