Summer has arrived, how do hypertensive patients spend the summer safely?
The body's blood pressure fluctuates regularly. Human blood pressure changes with the seasons, usually higher blood pressure in winter and lower in summer. Winter cold, blood vessels cold contraction, coupled with less sweating, and blood vessels in the blood volume will not change, blood pressure will rise. The summer heat, vasodilation, coupled with more sweating, blood pressure will be lower. Therefore, when taking medicine, patients with hypertension should also pay attention to the fluctuation of blood pressure according to the changes of the four seasons, increase or decrease the dosage appropriately under the guidance of doctors, and never stop taking medicine at will.

Secondly, within 24 hours a day, the fluctuation of blood pressure also has a certain rhythm. In the early morning, when people wake up from sleep, their sympathetic nerves begin to get excited, their heart rate increases and their blood pressure rises. There is a peak from 8 am to 10 am and 4 pm to 6 pm, followed by a slow decline, which drops to a minimum at night and maintains a certain level. This is why the same person takes blood pressure several times a day, and the value is different each time, sometimes even with a big difference.
In addition, the fluctuation of blood pressure will be affected by people's mood, exercise, diet and other external environmental factors. Blood pressure fluctuation was more obvious in patients with hypertension. Recognizing the volatility of blood pressure, we cannot draw conclusions based on the results of a single blood pressure measurement. If necessary, you can do 24-hour blood pressure monitoring to judge.
After the summer solstice, officially entered the summer season. In the face of blood pressure measurement results, many hypertensive patients have such a doubt in their hearts. "Recently, the blood pressure during the day is much lower than before. Can you stop taking the medicine or reduce the dosage?"
How to control blood pressure in summer?
Studies have shown that there is a difference between summer blood pressure and winter blood pressure. The average daytime blood pressure in summer is about 2mmHg lower than that in winter, the nighttime blood pressure and pulse pressure in summer are higher than that in winter, and the proportion of patients with non-dipper hypertension and simple nocturnal hypertension in summer is more than that in winter.
In summer, the blood pressure of patients with hypertension fluctuates greatly. Unless symptomatic hypotension occurs, it is necessary to avoid reducing or stopping antihypertensive drugs. Unnecessary drug withdrawal will lead to increased blood pressure and blood pressure fluctuation, and increase the risk of cardiovascular and cerebrovascular events. Because of this, summer is often the season of high blood pressure or high incidence of complications.
Hypertension patients in the end how to safely summer?
1. Blood pressure measurement frequently
If there are patients with high blood pressure at home, you must pay more attention in your life, have a blood pressure meter to measure blood pressure, and pay attention to your blood pressure at any time. In this way, you can have a better understanding of your blood pressure, so that you can control yourself or go to the hospital in time.
2. Lifestyle changes
Low-salt and low-fat diet, seven or eight points full per meal, eat more vegetables, drink more water, quit smoking and limit alcohol, exercise appropriately, choose morning or evening exercise, avoid strenuous exercise, control weight, avoid overweight or obesity, and keep a good mood.
3. Scientific adjustment of medication according to the doctor's advice
In summer, the weather is hot, the quality of sleep decreases, and the blood pressure rises at night. Due to the widespread use of air conditioning in the home, the temperature around the human body changes greatly, which can easily lead to large fluctuations in blood pressure, causing hypertension complications, and even life-threatening.
At this time, if patients with hypertension stop taking drugs at will, it will also induce cardiovascular and cerebrovascular diseases and endanger life. Because everyone has different tolerance to elevated blood pressure, medication must vary from person to person, and must not copy other people's experience and apply other people's prescriptions.
The treatment principle is the first choice of long-term antihypertensive drugs, which can keep blood pressure stable within 24 hours, better control blood pressure at night, and reach the standard for a long time, thereby reducing the occurrence of cardiovascular and cerebrovascular diseases. Of course, the principle of individualized treatment should also be followed. At the same time, patients with hypertension should be scientifically adjusted under the guidance of doctors.
24-hour stable control of blood pressure, especially at night, is the key to blood pressure management in summer. It is easier to control blood pressure in summer than in winter, so it is very important for patients with hypertension to take antihypertensive drugs in summer.
