In this regard, the experts said that the summer due to high temperatures, air humidity, oxygen content is reduced, when the body’s metabolism accelerated, the demand for oxygen and nutrients greatly increased, and the human body in order to dissipate the heat will make the blood gathered on the surface of the body, which leads to a reduction in the blood supply to the heart, the myocardial ischemia and hypoxia, resulting in high incidence of coronary heart disease. Secondly, due to the summer body sweating, the body water loss, blood viscosity increases, poor blood circulation, will also lead to myocardial ischemia and hypoxia, induced coronary heart disease.
