As people reach middle age, a variety of chronic diseases become more and more common. Hypertension is one of the most common ones. How does hypertension occur? In fact, the cause of hypertension is in our daily life. Dietary habits and mental factors are two of the most important causes of hypertension. First, why eating more salt can cause high blood pressure Because salt and water are a pair of very good friends, the two are often inseparable. The salt we eat is extracted from seawater. In the human body is the same, the amount of water will vary with the amount of salt. If there is too much salt in the diet, water tends to stay in the body. Too much water can not be expelled, the total amount of blood increases, and the heart pumping pressure increases accordingly. Expressed in the body, is an increase in blood pressure. In the long run, hypertension is formed. Second, the mental factors and how to cause high blood pressure Under normal circumstances, the body will distribute blood to various organs, so that everyone can be organized to complete their work, so that we can think and activities normally. When a person is in a highly stressed state, the oxygen consumption of the brain increases rapidly. In order to ensure the blood supply to the brain, many organs such as the liver, kidneys, and blood vessels in the stomach and intestines constrict up to reduce the consumption of blood. A problem then arises: the blood vessels throughout the body constrict together, and the pressure on the heart increases. This pressure, as reflected in the human body, is our blood pressure. This is the simplest reason for the increase in blood pressure.
