Why do high blood pressure symptoms get worse in winter? What to look out for?

Because the winter environment will be more complicated, the irresistible factors of the outside world have more challenges to our body, and the most important thing to pay attention to is to improve the body's resistance and maintain a better and healthier living habits.

Because the weather is very cold in winter, the blood circulation itself is slow, plus there is little exercise. It is easy to worsen the symptoms of high blood pressure. Be sure to pay attention to taking blood pressure medication in time, be sure to go to bed early, and don't stay up late.

In winter, when the temperature is low, vasoconstriction tends to increase blood pressure. It is important to wear thicker clothes when going out, keep warm, exercise regularly, and measure blood pressure regularly.

When the weather is cold, many people may have the impression that the blood pressure medication that was originally taken orally in the summer is good, but in the winter, the blood pressure cannot be controlled. Why is my blood pressure higher in winter?

1. Blood vessels constrict when cold

In winter, the temperature will drop significantly, and the blood vessels will also shrink when cold, and the constricted blood vessels will increase the resistance of blood circulation. As the peripheral resistance of the blood vessels increases, the patient's blood pressure increases.

Second, the capacity is increased in winter

Vasoconstriction increases peripheral resistance on the one hand, vasoconstriction reduces sweating in cold weather, and slowing blood flow in winter reduces renal perfusion and urination. Sweating less and urinating less increase blood volume, which also raises blood pressure.

3. Reduced exercise

In winter, when temperatures are cold, our desire to move decreases, so does outdoor activity, and the consequence of less exercise is an increase in obesity, which increases blood pressure.

Fourth, caused by winter tonic

In winter, we all know that we need tonic, and with the improvement of living standards, the achievability of tonic is also greatly increased, and tonic also brings obesity and increased volume load. These can also raise blood pressure.

Patients with high blood pressure should eat more fresh vegetables and fruits, and then should also drink more hot water, maintain a good attitude, do not be too anxious, and should also pay attention to the problem of keeping warm in winter, never catch a cold, and should take blood pressure medication on time.

Patients with high blood pressure in winter have the following precautions to pay attention to:

1. As the temperature becomes cold in winter and the blood vessels constrict, the blood pressure may further increase at this time, so strict blood pressure monitoring is essential.

2. In winter, the weather temperature is lower, at this time, it is not appropriate to pay attention to the blood pressure may be further increased, especially in the morning or night when the temperature is low, it is not recommended to exercise, you can choose to exercise when the temperature is high, such as noon;

3. The morning of winter is usually a time period of high incidence of cardiovascular events, at this time, from the sleep state to the awake state, the sympathetic nerve activity will be enhanced, and the blood pressure will also increase. If the blood pressure is high, it is recommended to take antihypertensive drugs in the morning to lower the morning peak.

Normal blood pressure in summer and high blood pressure in winter, which is caused by climate change. In summer, due to the hot weather, the blood vessels dilate, the peripheral resistance decreases, and the blood pressure does not increase, but in winter, due to the cold weather, the blood vessels constrict, the peripheral resistance increases, and the blood pressure is high, which is a normal human physiological phenomenon. Of course, changes in blood pressure are not only related to vascular resistance, but also to heart rate, myocardial contractility, and the elasticity of arterial blood vessel walls.

In summer, when the temperature is high, the peripheral blood vessels of the body are in a state of relaxation, and the pressure on the peripheral blood vessels is less, so the blood pressure is lower than that in winter, and even in the normal range. In winter, due to the drop in temperature, the peripheral blood vessels of the body are in a state of contraction, and the pressure on the peripheral blood vessels is also greater, so the blood pressure in winter is often higher than that in summer, which is similar to the principle of thermal expansion and cold contraction in physical phenomena, and it is recommended that patients pay attention to the status of family self-measurement of blood pressure.

Home self-test blood pressure refers to more than 3 times on the same day, blood pressure levels higher than 140 90mmHg, it is recommended that patients go to the cardiology outpatient department of the local hospital for treatment, listen to the advice of the cardiologist, whether to start the hypertension medication**, and need regular outpatient follow-up. In the case of low blood pressure in summer or high blood pressure in winter, a comprehensive assessment is made of whether appropriate drugs need to be withdrawn or appropriate drugs added to reduce fluctuations in the patient's blood pressure level.

Patients with high blood pressure usually have high blood pressure in winter and low blood pressure in summer, this is because people's blood vessels are elastic, according to the principle of thermal expansion and cold contraction, the environment is hot in summer** blood vessels dilate, blood flow increases, and due to sweating in summer, blood flow decreases, these factors will lead to low blood pressure in summer. In winter, the weather is cold** vasoconstriction, peripheral vascular resistance increases, exercise decreases, sweating less, and blood flow is relatively increased, all of which can lead to high blood pressure in winter. Therefore, for patients with hypertension, it is necessary to closely monitor the blood pressure level, adjust the dosage of hypertension drugs according to the blood pressure, keep the blood pressure level stable, and reduce the occurrence of cardiovascular and cerebrovascular diseases.

It does happen that blood pressure will be more normal in the summer because we exercise a lot, and in the winter we don't exercise much, and the blood pressure will rise.

Yes. It is very normal for blood pressure to be higher in winter than in summer, because when it is hot, blood vessels dilate, causing blood pressure to become low.

Yes, because of excessive sweating in the summer, blood pressure is maintained at a normal level.

In nonsense, the level of medicine is limited.

Because the temperature is very cold in winter, we have to go to the fire test to maintain a normal body temperature.

Because the human body is unstable in winter, it is difficult to control high blood pressure.

Because the winter is cold, it is more difficult to control the aspect of eating.

This is probably because high blood pressure is easy to develop in winter, so it is difficult to control.
