By causing narrowing of the blood vessels which increases the blood pressure.
Explanation:
The winter usually causes an increase in blood pressure just as the summer causes a decrease.
This is because low temperatures cause blood vessels to narrow, just as high temperatures cause them to expand.
When the blood vessels are narrowed, more pressure is required to pump blood through them, hence increasing the blood pressure.
