Ever wondered... why you should wear a hat in winter besides your mother telling you to?

On a cold snow blizzard day like to day, remember your mothers words of wisdom: "You need to wear a hat because you lose more heat through your head than the rest of your body. 

Well is this a myth or just plain fake/alternative news.

True or false?

While this is not exactly true, wearing a hat on chilly days will definitely help you stay warm. Here's how.
Warmblooded animals control their body temperature by balancing heat production (from cell function) and heat loss (to the environment). Cold surroundings do lots of sneaky things to steal the heat from your body. If you come in direct contact with a cold object, like sitting on a snowy hill, you lose heat conduction. (Conduction is the process that causes heat transfer when two objects are touching each other - in this case, the snowy hill and your butt.) If you come in contact with cold air, you lose heat through convection. (Convection is the process that causes heat transfer when a gas moves past an object - in this case, cold air moving across your skin.) There is even something called the "chimney effect" that can work against you. Dense, cold air works its way into your pants and sleeves and pushes warm, light air out through other openings. Wind also works through convection, which is why blustery, cold days are the worst.
If it's cold outside, the brain directs a number of actions to keep your core temperature steady. The blood vessels in your skin contract (get smaller) to preserve heat. That's why your hands and feet may become pale and cool in cold settings. By redirecting blood flow, the brain keeps your muscles and organs warm even though your hands, feet and skin become cold. You feel cold, which encourages you to put on warm clothes. If it's really cold, you may even shiver, which increases heat production in your muscles.
Okay, back to hats.
As noted above, you lose heat from any part of your body that comes in contact with a cold environment. And the part of your body that is most often exposed to the elements during the winter is your poor defenseless head!

So listen to your mother and put a lid on your noggin!
