New Study: Crawl Back Inside Your Mom to Survive Winter

This news would have been super useful had you still been inside of your mother when they discovered it.

If you want your children to survive long, cold winters, a new study would like you to hold off getting busy for a few months so your kid can burst forth into the world just after next winter's polar vortices destroy all you know and love.

Unborn babies remain an ambient temperature, thanks to their mother's body. But the weather conditions outside the womb can still profoundly impact infants throughout life, according to a new study published in Social Science and Medicine.

Here's how: Being in utero during cold weather could help protect your heart against wintertime stress.

Cold weather causes your blood vessels to narrow, raising blood pressure and risk for heart attack and stroke. It's well-documented that heart-related deaths — which are the number one killer in the world year-round — spike during colder months.
