Why does blood thicken in cold weather?

The effect of cold weather on circulation

Another explanation is that the body must work harder to regulate its temperature in cooler weather. As a result, thermal stress can cause the blood to thicken and form blood clots.

What happens to your body when you are in cold weather?

What causes blood to thicken?
