What should hypertensive patients pay attention to in summer?

High temperature in summer, middle-aged and elderly patients with hypertension should arrange their lives scientifically and reasonably, and pay attention to the following points: 1. Don't forget to replenish water. Sweating more in summer, blood viscosity may be higher, so you should replenish water in time, and drink water even if you are not thirsty at ordinary times to dilute blood and reduce the risk of thrombosis. The simplest and most effective way is to drink boiled water, and have a big cup in the morning, noon and evening. In addition, you can drink green tea, chrysanthemum tea and so on. According to your personal habits. These drinks have the function of preventing hypercoagulability of blood. Of course, alcohol and drinks with high sugar content should not be drunk too much.

2. Avoid sudden changes in environmental temperature difference. Many families use air conditioning. Although it is cool indoors, it often leads to a large temperature difference between indoor and outdoor. If the frequency of entering and leaving the air-conditioned room is too high, the sudden change of temperature difference will cause repeated contraction and relaxation of cerebral blood vessels, which is prone to accidents. Therefore, under normal circumstances, middle-aged and elderly people should try not to turn on the air conditioner in the room, but use an electric fan to blow slightly against the wind, so that the room temperature will not be too low and they will feel cool. If the air conditioner is turned on, the temperature difference between indoor and outdoor should not exceed 7℃, and the times of entering and leaving the air-conditioned room should be reduced as much as possible.

3. Adhere to diet conditioning. The appetite is poor in hot weather, but we should eat regularly and quantitatively under the principle of low salt, low fat and low calorie to ensure the necessary nutrition. Of course, the diet should be light and eat more green leafy vegetables, tomatoes, bean products and fish.

4. Pay attention to the choice of antihypertensive drugs. Because the blood pressure tends to be low in summer, the relative fluctuation is large. In order to maintain the antihypertensive effect and ensure that all organs (especially the heart, brain and kidney) can get enough effective blood flow, it is not advisable to choose drugs with high antihypertensive intensity, but to choose long-acting antihypertensive drugs with definite curative effect and lasting effect, which can smoothly reduce blood pressure for 24 hours.
