Is blood pressure high or low in summer

Hypertension is a chronic disease. Once people have symptoms of high blood pressure, it is impossible to cure it completely. Patients can only rely on medication to maintain stable blood pressure in daily life. They must also pay special attention to their diet and avoid eating too salty food. The blood pressure of patients with hypertension does not always remain at the same level. It changes according to the season and the patient's mood. Is the blood pressure high or low in summer?

The increase in blood pressure is caused by the interaction between genetic genes and external environmental factors. The external environment will cause a series of neurohumoral adaptive adjustments in the human body. Seasons can affect changes in blood pressure, especially in the elderly. Blood pressure will drop slightly in summer and rise significantly in winter. Generally, blood pressure in winter is 1.6/0.8 kPa (12.0/6.0 mmHg) higher than that in summer. This is mainly due to the influence of temperature. Skin blood vessels dilate in summer and contract in winter. There is evidence that for every 1°C drop in temperature, systolic blood pressure increases by 0.17 kPa (1.3 mmHg) and diastolic blood pressure increases by 0.08 kPa (0.6 mmHg). In winter, the temperature drops, the adrenaline level in the human body rises, and the blood vessels on the surface of the body contract to reduce heat dissipation. At the same time, adrenaline can increase the heart rate and cardiac output, which will lead to an increase in blood pressure. In summer, the external environment is hot, the body surface resistance decreases, and blood flow increases. At the same time, blood pressure also decreases due to sweating and decreased blood volume in summer. Therefore, some hypertensive patients often suffer from stroke due to a sharp increase in blood pressure caused by cold stimulation.

When the weather gets cold and blood pressure rises, people will take anti-hypertensive drugs to lower blood pressure, but there is no obvious effect. Don't panic at this time. Only if the blood pressure continues to rise above 20 mmHg do you need to adjust the medication. But if the blood pressure is within 20 mmHg, you can consult a doctor whether to increase the medication. Don't decide at will to prevent the blood pressure from fluctuating too much.

It is necessary to develop the habit of checking blood pressure. If the blood pressure is stable, the patient can measure the blood pressure before taking the medicine for the first time each day. If it is unstable, it should be measured before each medication. The measurement can be done 1-2 times a week.

Foods with too high salt content should be eaten less or not at all. For example, people with high blood pressure should try to eat less or no high-salt foods such as hot pot, malatang, and braised meat. In your daily diet, you can add flavor through vinegar, mustard, sesame oil, onion, etc., so that you don’t feel that the food tastes too bland, but never use MSG, soy sauce, hot sauce, etc.

You should know that cold weather causes blood vessels to constrict and blood pressure to rise, so you should keep warm whether indoors or outdoors, avoid places with lower temperatures and don't stay there for too long. Although people's daily routines should be regular and combine work and rest, they should avoid going out for morning exercises or walks when the weather is cold. In particular, some patients with unstable blood pressure should pay more attention to keeping warm.

Through the above introduction, I believe everyone knows that blood pressure will drop slightly in summer, the reasons for high blood pressure in winter and various measures to increase blood pressure in winter. This is not only for patients with hypertension, but also for ordinary people. They should pay more attention to their bodies, keep warm in winter, maintain a good lifestyle, and be responsible for themselves.
