女人为什么总比男人感觉更怕冷?

The fairer sex has a higher percentage of body fat and conserves¹ more heat around the core. That helps keep vital organs nice and toasty but not the extremities—and when your hands and feet feel cold, so does the rest of your body.

 

Plus, research suggests that women have a lower threshold for cold than men.

 

When exposed to the same freezing temperature, the blood vessels² in women's fingers constrict³ more than men's do, which is why they turn white more quickly.
