Many people who are taking antihypertensive drugs do not work, and they need to add or change medicine. Some The friend did not adjust the medication in time, which resulted in an accident.
So, why is blood pressure unstable when high blood pressure enters the seasonal exchange? Why is the blood pressure high when the weather hasn't cooled down yet?
This is actually related to the following factors:
1. When the vasoconstriction weather turns cold, our blood vessels will contract in order to adapt to changes in the environment. When the blood vessels contract, the blood flow is slow and the blood circulation resistance increases, leading to a rise in blood pressure. high.
2. Too much salt, even if you eat the same amount of salt in winter as in summer, the content of salt in the body is different in different seasons. In summer, due to a lot of sweating, we eat a lot of salt through sweating along with sweat. Discharge, we all feel this way. This is the reason that sweat is salty. When the season changes, the weather turns colder and less sweating makes it difficult to discharge salt in the body, which will cause blood pressure to rise.

After the fall, in order to adapt to the environment, the body will release epinephrine and norepinephrine to increase metabolism, which will lead to faster heartbeat, increased myocardial contractility, vasoconstriction, and blood pressure Will also rise. This is a protective effect.
5. In autumn and winter, sweating is less, and the blood volume of will increase correspondingly compared with summer, which is also one of the factors that increase blood pressure.
Generally speaking, the average systolic blood pressure of the human body in winter is 12 mmHg higher than that in summer,The average diastolic blood pressure is 6 mmHg higher than in summer, so what can we do to better keep blood pressure stable?
