Is it normal for normal people to raise their blood pressure from 12 to 135 when the weather is cold?

Hello, it's not necessarily caused by the cold weather. Activity is also an important factor, and blood pressure is constantly changing, not a fixed value.

The blood pressure of normal people fluctuates within 2-3mm Hg in a day. The fluctuation range of the elderly is larger than that of the young. Under the influence of sleep, people's blood pressure in a day has two peaks and two valleys: the first peak is 6-8 o'clock in the morning; It began to decline after 8 o'clock, and the first trough was from 12 noon to 2 pm. Then blood pressure began to rise, reaching the second peak at 5-8 pm; After that, the blood pressure dropped to the lowest point in the whole day at 1-2 am, which is the second trough, and then the blood pressure gradually increased.
