The incidence of heart disease is high in summer. What is the reason?

In summer, the temperature is very high and the weather is very hot. Nowadays, many heart patients often get sick. Because if the temperature exceeds 30℃ for several days in summer, it will increase the incidence of cardiovascular diseases. Therefore, patients with heart disease must do a good job in prevention in summer and must not relax.

First, how easy it is to form blood clots when sweating in summer. It is very hot in summer. For people who sweat easily, a little movement can make them sweat a lot. Frequent sweating can lead to the loss of body fluids in the body. If a large number of body fluids are lost and water is not replenished in time, it will easily lead to an increase in blood viscosity. When the blood viscosity in the body increases, the blood circulation ability will deteriorate, so many important organs in the body will be in a state of hypoxia and ischemia, including the heart. Moreover, when the blood circulation in the body slows down, thrombotic factors will also form in the body, leading to heart disease.

Second, the heart pressure increases. When the weather is hot in summer, people's sympathetic nerves will become extremely excited and their heartbeat will accelerate. When the heart beats faster, myocardial contractility and myocardial oxygen consumption will also increase, so the burden on the heart will also increase. When the burden of the heart becomes heavier, people's normal breathing can't meet the myocardial oxygen consumption of the heart, so it will cause a heart attack.

Third, the temperature rises gradually in summer, so basically everyone can't live without air conditioning in summer. When the indoor temperature of air conditioner is too low, the temperature difference between indoor and outdoor will be too large. When heart patients go in and out, they alternate between cold and hot, and the blood vessels in the body are very difficult to adapt, so they will induce heart disease. And when the weather is hot in summer, many people like to drink cold drinks and eat ice cream. When people suddenly drink cold drinks and eat ice cream when it is hot, it will lead to sudden contraction of blood vessels, which will easily increase the burden on the heart and lead to a heart attack.
