Because of the high temperature in summer, it is easy to lose too much water when going out because of the open sweat glands, which may cause heatstroke or other adverse reactions. Patients with hypertension should pay more attention when drinking water! Because the way of drinking water is not correct, it will also affect blood pressure fluctuation! Sweat a lot in summer. Sweat contains a lot of sodium and other trace elements. These substances can help balance the osmotic pressure in the body, and their content has a certain impact on blood pressure. If you drink plenty of water immediately after sweating, it will easily lead to a sudden drop in blood pressure, leading to cerebral ischemia and fainting. Secondly, if you don't drink enough water, because of the blood concentration, when you are sleeping or quiet, you suddenly enter a low temperature environment. Because of the high blood concentration and slow blood flow, it is very easy to have blood clots, which will cause hypoxic damage to your heart or brain.

1, blood pressure is stable, pay attention to diet and rest.

Besides drinking water, diet and rest also have a great influence on blood pressure. Because of the hot weather, most people will avoid eating greasy food, so it goes without saying that a light diet is basically ok for many people. However, you can also help control blood pressure by eating some foods rich in potassium and magnesium, such as celery, cucumber, garlic, mung beans and bananas. Because potassium and magnesium can not only protect the cardiovascular system, but also promote sodium excretion, which is conducive to lowering blood pressure and protecting cardiovascular and cerebrovascular diseases, so the more people with poor renal function, the better.
