The weather is hot in summer. What should patients with hypertension pay attention to to keep their blood pressure stable?
We all know that patients with hypertension are most afraid of rising blood pressure, so they need to take antihypertensive drugs for a long time to control their blood pressure. But in summer, many patients with high blood pressure will find that their blood pressure suddenly returns to normal. Thinking that their condition has recovered, they stop taking their medicine without permission. In fact, this is very dangerous.
The reason why blood pressure is "normal" in summer is mainly related to the temperature. We all know the principle of thermal expansion and contraction. In hot summer, our blood vessels will relax relatively, and the blood flow will be smoother. The pressure on the blood vessel wall is also relatively small, so blood pressure is low. In autumn and winter, blood vessels will shrink relatively, and blood pressure will naturally be high.
For patients with high blood pressure, although their blood pressure drops in summer, due to the high temperature, accelerated heartbeat, and excessive sweating in summer, there is a possibility of myocardial infarction and cerebral infarction, so the risk is high. People with high blood pressure should pay special attention in summer.
1. Adjust antihypertensive drugs.
The blood pressure of hypertensive patients generally drops in summer, but do not blindly stop taking medication to avoid other dangerous complications. It is recommended to go to the hospital for a check-up and appropriately reduce the dosage or adjust the medication according to the doctor's advice.
2. The temperature of the air-conditioned room cannot be too low.
Whether you are at home or at work, it is recommended that the temperature in the air-conditioned room should not be set too low, and the temperature difference with the outdoors should not be too large, because hot and cold periods can easily cause blood pressure fluctuations and cause cardiovascular and cerebrovascular diseases.
3. Eat a light diet and replenish water in time.
The human digestive system is relatively weak in summer, so the diet should be light and easy to digest. Greasy food is not easy to digest. Eat less and more fruits and vegetables rich in vitamins and trace elements. In addition, the weather is hot in summer, and water loss is relatively large, which can easily cause blood clots. Therefore, you need to replenish water every day. The amount of water you drink per day is about 2000ml.
