Can hot weather affect blood pressure?
The level of blood pressure is not only closely related to heart function, vascular resistance and blood volume, but also influenced by factors such as nerves and body fluids. In addition, differences in age, season, climate and occupation will also lead to different blood pressure values; Exercise, eating, mood changes, defecation, sexual intercourse, etc. may also increase blood pressure. On the contrary, things like rest and sleep will lower blood pressure.
2 Does hot weather affect blood pressure?
Hot weather may affect blood pressure.
Generally, the blood pressure in summer is relatively low compared with that in winter. However, when the weather is hot, people are prone to nervous anxiety and other emotions, which may cause people's blood pressure to temporarily rise, and the amount of increase varies from person to person.
Because it is cold in winter, blood vessels are easily contracted by cold, which increases the pressure on blood vessels. At the same time, it is dry in winter, and people drink less water, which makes blood sticky. Therefore, the temperature in winter is slightly higher than that in summer, and cardiovascular diseases are more likely to occur.
3 Why does the blood pressure change in weather
When people are emotional and feel anxious and fidgety in hot weather, higher nervous activity's disorder will be caused, which will increase the reactivity of higher autonomic nerve centers that regulate blood pressure, increase the secretion of vasoactive substances such as catecholamines in blood, and make arterioles spasm and contract, thus raising blood pressure.
4 How to control blood pressure in hot weather
1. Hot weather has a great influence on blood pressure, so it is of great significance to pay attention to controlling emotions and maintaining peace of mind to prevent the occurrence and development of hypertension.
2. In hot weather, people tend to sweat a lot, and blood concentration tends to affect blood pressure, so we should replenish enough water, even if we don't feel hot, we should pay attention to replenish water, and we should replenish water in time if we sweat for a long time.
3. Stick to diet therapy. Daily salt intake should be controlled below 5g, and fresh vegetables, fruits and bean products rich in potassium and calcium should be increased.
4. Ensure adequate sleep. When the sleep quality of hypertensive patients declines in summer, blood pressure may rise at night, so we must do a good job of cooling and heatstroke prevention to maintain normal sleep.
5. Adjust antihypertensive drugs. In summer, if the blood pressure of hypertensive patients fluctuates greatly, they can adjust their medication under the guidance of doctors to avoid the occurrence of cardiovascular and cerebrovascular diseases caused by too low or too high blood pressure.
