Will blood pressure rise or fall in cold weather?

It is an inevitable phenomenon that the temperature drops and the blood pressure rises. Blood vessels also have the characteristics of "expansion with heat and contraction with cold", that is, when blood vessels contract with cold, blood pressure will rise. Due to the climate, the blood pressure in winter will be higher than that in summer.

When the weather suddenly gets cold, or the temperature difference between morning and evening is large, the blood pressure fluctuation will be more obvious. Generally speaking, in winter, the blood pressure of patients with hypertension increases by 5- 10 mm Hg, and the highest can even reach 20 mm Hg. On the other hand, due to poor vascular elasticity, the elderly mainly show systolic blood pressure, that is, hypertension; High blood pressure in young people is mainly due to high vascular resistance. In winter, diastolic blood pressure, that is, low pressure, rises slightly.

Precautions for patients with cold weather and hypertension

After entering autumn, patients with hypertension are more sensitive to temperature changes, which leads to the aggravation of heart failure and the obvious increase of acute angina pectoris. Therefore, patients with hypertension should pay attention to self-protection when the seasons change. In the period of seasonal changes, the more attention is paid to the prevention of various risk factors, the more we can avoid the fluctuation of blood pressure and reduce the occurrence of various dangerous events.

1, blood pressure will be higher in cold weather. Not that the medicine doesn't work. Patients should not panic and rush to change medicine. As long as the blood pressure continues to rise above 20 mm Hg, medication must be adjusted. It is suggested that patients in the range of 20 mm Hg can consult a doctor to take the method of increasing the amount or adding drugs to avoid greater blood pressure fluctuation.

2. Develop a good habit of monitoring blood pressure. For example, once a week before, maybe once every three days or once a day in winter. If you find that your blood pressure is unstable, you'd better consult a cardiologist or hypertension expert.

People like to eat all kinds of hot pot in cold weather, including spicy incense pot, mala Tang, brushing meat, etc. These foods are too salty for patients with hypertension, so try to eat as little as possible or even not. If you feel that the daily diet tastes light, it is recommended to use vinegar, mustard, sesame oil, onion and other seasonings to increase the taste, but do not use monosodium glutamate, soy sauce and hot sauce.

4. Cold weather will raise blood pressure. At this time, patients with hypertension should pay more attention to keep warm, go to places with extremely low temperatures and don't stay outdoors for a long time. It is suggested that the indoor temperature should be 18~25℃, the temperature difference between indoor and outdoor should not be too large, and the room should be ventilated frequently.

5. Patients with unstable blood pressure should not go out for morning exercise when the weather is cold, and their daily routine should be regular, and work and rest should be combined to avoid excessive fatigue.

6, tonic should be moderate. In winter, people exercise less, plus a lot of tonic hot food and nourishing medicinal liquor, which can easily lead to elevated blood lipids and cardiovascular and cerebrovascular diseases.
