Summer sauna days, sweating more relative to drinking less water, blood sticky, coupled with fatigue, lack of sleep and other factors, more likely to cause a cardiovascular disease explosion. Summer temperatures rise, especially in hot weather, the human subcutaneous blood vessels expand, the blood flow to the skin than usual increased by 3-5 times, while the amount of blood flow back to the heart decreased, which will directly affect the blood supply to the heart muscle. When people are in high temperature, sympathetic excitability increases, heart rate accelerates, coronary arteries contract, and myocardial oxygen supply decreases, which can also increase the attack of coronary heart disease. Summer sauna days, sweating more relative to drink less water, blood sticky, coupled with fatigue, lack of sleep and other factors, more likely to cause cardiovascular disease explosion. Summer is prone to “cardiovascular disease” behavior inventory summer, there are many adverse cardiovascular behavior, many people may not know. Cardiovascular accidents are triggered by certain factors. If we are aware of the existence of these problems, cardiovascular disease can be completely avoided. 1, the air conditioning is too cold, the temperature difference between inside and outside the house is greater than 8 ℃: Some people like to turn the air conditioning temperature very low (as low as 20 degrees Celsius), or a fan blowing is a whole night, especially in the summer just home from the outdoors, hoping that this can make their own “freeze” down. As the temperature difference between indoor and outdoor is greater than 8 degrees Celsius, a sudden drop in temperature, a hot and a cold, blood vessels will be from the original diastolic state into a contracted state, laying the groundwork for increased blood pressure. Especially for older people, the air conditioning temperature is too low and may be life-threatening due to unstable blood pressure. When the weather is hot, you can turn on the air conditioning, but not too low, about 25 ℃ is appropriate; when entering the room from outside, it is best not to drink ice water or eat ice cream and other frozen food. 2, summer choose the morning exercise: summer day, the coolest is the morning, so there are many people will exercise exercise time set in the morning 6-10 o’clock. In fact, for their own cardiovascular disease or the elderly, 6:00 a.m. to 10:00 a.m. is the “devil’s time”, because at this time, the sympathetic nerves are very excited, at this time exercise is easy to induce cardiovascular disease, resulting in sudden death. Avoid the high incidence of coronary heart disease, it is best to schedule exercise in the cooler afternoon or evening, do not exercise in the hot sun, and exercise time should not be too long. When the weather is hot and muggy, the air humidity in the “sauna days”, should minimize outdoor activities. 3, like to eat spicy, drinking, especially cold beer: summer temperature, no appetite, in order to open the appetite, many people choose to eat heavy and spicy, or fried food. But eating too greasy will make the blood sticky, easy to form blood clots; at the same time, fried food contains trans fatty acids, too much intake, will lead to atherosclerosis. In summer, it is better to drink more water, eat more fruits and vegetables, eat more orange juice and banana fruits, and eat less fried food. 4, stay up late, sleep deprivation, emotional irritability: the summer weather is hot, it is difficult to sleep at night, it is during the broadcast of the Olympic Games, stay up late to watch the game, the morning to work, poor sleep treatment, will lead to unstable blood pressure. And impatient mood or emotional out of control, blood pressure rises, increasing the chances of suffering a myocardial infarction. Emotions should be stable and get up in order. If you go to sleep late at night, you should not get up too early in the morning, take a proper rest at noon to supplement the lack of sleep, and take a half-hour nap to make a low point in the blood pressure and heart rate curve.
