Is it normal for blood pressure to drop in summer? In order to spend the summer safely, we must pay extra attention to these five points.

It's getting hotter and hotter, and many friends with high blood pressure have done nothing, but their blood pressure has dropped inexplicably! Is this normal? Will it have any bad effects on your health?

why does blood pressure drop by itself in summer? There are two main reasons: the temperature is relatively high in summer, and the relative resistance of blood vessels to dilation decreases, even if the blood flow does not change, the blood pressure will drop; Sweating more in summer, a lot of water in the human body is lost, blood flow will decrease, and blood pressure will also decrease.

So it's normal for blood pressure to drop in summer, and it won't do harm to the body! But at this time, you can't stop taking antihypertensive drugs without your own feelings, which will make the blood pressure fluctuate greatly, which will cause dizziness, shock and other symptoms, and even be life-threatening in severe cases!

If your body is obviously affected by the temperature and your blood pressure is obviously low, if you follow the dosage of antihypertensive drugs in winter, your blood pressure will drop too low, causing dizziness, general weakness and insufficient blood supply to the brain. At this time, don't reduce the dosage yourself, but make adjustments after consulting a doctor.

Although the temperature rise will lower blood pressure, it will also increase blood pressure because of the hot weather, and the blood pressure will rise and fall, and the fluctuation range is greater than that in winter. Therefore, for patients with hypertension, in addition to a light diet and less salt, several precautions should be added in summer to stabilize blood pressure and spend the summer safely!

Good sleep

In summer, the weather is hot and vulnerable to mosquito bites, and sleep is easily affected, especially people with high blood pressure are more likely to cause blood pressure fluctuations, leading to cardiovascular and cerebrovascular diseases. Two to three hours before going to sleep, you can spray mosquito repellent in the bedroom to ensure that there is no mosquito disturbance and no choking smell during sleep; Develop a regular sleep, don't stay up late, and ensure at least 7 hours of sleep every day!

The indoor temperature is suitable

The body of the elderly population is not sensitive to heat, even if the air conditioner is not turned on, it will easily lead to asymptomatic blood pressure fluctuation; In addition, the air conditioning temperature is too low, the temperature difference between indoor and outdoor is too large, and the blood vessels suddenly contract and suddenly relax, which will also lead to blood pressure fluctuations and induce cardiovascular diseases; Therefore, when blowing air conditioning in summer, it is best to control it at 27-28 degrees, and the temperature difference between indoor and outdoor should not exceed 7 degrees to keep the indoor temperature constant.

Ensure adequate water intake

There is a lot of sweat in summer. If you don't replenish water in time, it is easy to reduce fluid accumulation in the body and lead to blood pressure fluctuation. Drinking more water can dilute blood, increase blood volume, control blood pressure and prevent thrombosis. When you go out in summer, you should take water with you or drink it nearby. Don't wait until you are thirsty.

You must eat less cold drinks

A large amount of cold drinks ingested by the human body will suddenly stimulate the stomach and make the blood vessels of the whole body contract, which will lead to an increase in blood pressure, aggravate the condition and induce cerebral hemorrhage. Therefore, friends with high blood pressure should not drink cold drinks, replace them with mung bean soup, or eat more cool fruits and vegetables such as loofah, wax gourd, bitter gourd and watermelon to relieve the heat.

Drink less and eat less seafood

The hotter the weather, the more delicious the seafood, and the better the draft beer! However, seafood contains a lot of high protein and high purine, and eating more will lead to weakened metabolic capacity and increased blood pressure. Drinking alcohol will lead to an increase in heart rate, which is also a major cause of high blood pressure. Therefore, in summer, patients with hypertension must stay away from this unhealthy but comfortable lifestyle, and it is most important to insist on less salt and light.

When summer comes, don't think that everything will be fine if your blood pressure drops. What you should do is to keep your blood pressure stable. Don't let your blood pressure stimulate like riding a roller coaster. Stick to the above five points, and this summer will be safe and easy!
