Why Kids Don’t Feel The Cold 🥶

Morning Kiddies!

Picture this:

It's a freezing cold day.

You're out with your family.

And your parents are like:

But the thing is, you're just… not that cold.

How come kids just don’t feel the cold?

Well, there's actually a reason behind this.

See, your body has these 2 types of fat.

White fat is the one we tend to think of as “fat”.

It exists all throughout your body and is used kinda like energy storage.

But brown fat… is a little different.

These things are basically little sacks of energy and things called mitochondria.

Mitochondria being:

Anyway, thanks to these mitochondria, brown fat acts less like an energy reserve and more like a furnace inside the body.

And unlike white fat, brown fat can only be located in very few areas:

Now, here's the key.

These fat deposits overlap with lots of major blood vessels.

This means that as blood flows through these blood vessels, the brown fat deposits heat it up.

The brown fat around the neck vessels heats up the blood that goes to the brain.

The deposits in the shoulders heat the blood that flows quickly into the heart and gets pumped around the rest of the body.

Now, here’s the thing…

As you get older, you have less and less of this brown fat.

Kids have tons of it.

Generally, brown fat content peaks during the teenage years.

Which might explain why teenagers are able to go outside in the freezing cold in just a t-shirt and shorts.

But, as you get older, your amount of brown fat reduces more and more.

Until when you're super old… you barely have any.

This is also probably why old people seem to always be cold.
