Women also tend to have a lower metabolic rate than men, which reduces heat production capacity during cold exposure, making women more prone to feeling cold as the temperature drops.

What's the warmest part of a woman's body?

Metabolism and heat

Blame our slower metabolisms. A study in the Journal of Applied Physiology showed that the resting metabolic rate, or the amount of energy your body burns at rest, was 23% higher in men than women. A slower metabolism causes women to produce less heat so they tend to feel colder.
