Why does the cold weather raise our blood pressure, and just how big can the change be?
In: Biology
Not a Dr., but from what I’ve learned your blood thickens in the winter, which makes it harder for your heart to pump it around. Plus, your heart needs to pump faster if you’re out in the cold to keep your extremities from freezing.
Coldness makes the blood vessels shrink, which means less space for the blood, hence higher blood pressure.
