What causes high blood pressure in summer?

Due to the environment, season, mood and other reasons, patients with hypertension can easily raise their blood pressure, thus causing many dangerous complications, and hypertension will occur in summer. So, what causes high blood pressure in summer? Let me tell you the cause of high blood pressure in summer!

What causes high blood pressure in summer?

1 temperature rise Many hypertensive patients believe that after the temperature rises in summer, the blood vessels dilate and soften, and the blood pressure will be lower than usual. Professor Jiao reminded that only a few patients with mild hypertension will have relatively low blood pressure in summer, but they should not reduce the dosage of antihypertensive drugs at will. If necessary, 24-hour ambulatory blood pressure monitoring should be carried out under the guidance of a doctor, and medication should be reduced as appropriate according to the specific situation, otherwise blood pressure will rise blindly.

2 emotional irritability, hot summer climate, especially the next Jiangnan area will enter? Huang Mei? When the rainy season comes, the sultry weather will make people feel irritable, nervous and anxious, which will lead to hyperfunction of sympathetic nerve, increased secretion of adrenal hormones, vasospasm and contraction, which will lead to an increase in blood pressure and easily lead to myocardial infarction and stroke. Professor Jiao reminded such patients that they must pay attention to self-regulation at ordinary times, keep a good mood, and try to find a cool place to escape the heat in hot and muggy climate.

3 salt intake increases in summer, sweating will increase, and salt in the body will also be lost with sweat, so summer usually consumes more salt than usual to meet the needs of the body; In addition, in summer, people's taste function declines and they often eat tasteless food. In addition, the heat is unbearable, and their appetite decreases. They always like to eat heavy things to increase their appetite, and inadvertently ingest more sodium salt, which will raise their blood pressure. Such people must pay more attention to monitoring blood pressure, seek medical advice in time if there is a significant increase, and pay more attention to supplementing water when supplementing salt to avoid the occurrence of vascular embolic diseases such as myocardial infarction and cerebral infarction caused by blood concentration.

4 Insufficient rest There is a common problem of poor sleep quality in summer. Many hypertensive patients don't get enough rest because of the climate, and lack of sleep leads to high blood pressure.

How should hypertension be treated in summer?

1 Ensure normal sleep time.

People's blood pressure will only drop during sleep, so we should keep the blood pressure regular day and night. When the sleep quality of hypertensive patients decreases at night in summer, the blood pressure will increase at night, which will aggravate the damage to cardiovascular and cerebrovascular diseases. Therefore, patients must ensure normal sleep.

2. Adhere to the principle of reasonable diet.

In summer, people's digestive tract function declines, their appetite declines, and there is more water loss, especially in patients with hypertension. On the one hand, the diet should be light and nutritious. In summer, sweating is more, blood is easy to concentrate, and blood clots are easy to occur when people are sleeping or quiet. Therefore, patients with hypertension should always replenish water in summer, even if they don't feel too hot, they should always drink water to prevent cardiovascular and cerebrovascular diseases such as increased blood viscosity.

3 avoid hot and cold? Stimulation?

Patients with hypertension should pay special attention to their living environment. Indoor room temperature should be kept between 22 ~ 26 degrees Celsius, and indoor air circulation should be maintained. The blood pressure of many hypertensive patients is always well controlled, but in summer, the blood pressure is unstable, which is related to improper use of air conditioners. Especially when I just came home from a hot external environment, the air conditioning temperature was too low. When it is cold and hot, blood vessels will suddenly change from the original relaxed state to the contracted state, which paves the way for the increase of blood pressure.

4 appropriately reduce the intensity of exercise

Because the human consumption in summer is greater than that in other seasons, the behavior of patients with hypertension should be adjusted accordingly, focusing on rest. However, this does not mean that you can lie down and rest in summer without exercise. In this season, it is really necessary to adjust the exercise time and reduce the exercise intensity. The exercise time in the morning should be earlier than usual, and the exercise time in the evening can be chosen. Never do physical activity in the hot sun after sunset. Elderly patients should make their exercise comfortable, while middle-aged patients can make themselves feel a little sweaty and laborious. The duration of activities should be controlled within 30 minutes to 60 minutes, and the intensity of activities should be lower than usual. Sports activities suitable for patients with hypertension in summer include boxing, practicing medical qigong, walking, jogging and swimming. These activities are conducive to relaxing the spirit, regulating nerves, dilating blood vessels and improving blood flow.
