This morning I have cold hands. How very fitting that the weather has turned very fall like on the eve of the first day of fall. I am sure by the time my summer clothes are just about buried beneath sweaters and jeans it will warm up again but in the meantime I am rubbing my hands together! And as I am doing this I am thinking about how cool this little scientific principle is.
It is why you can make fire by rubbing two sticks together. Pretty cool right?!
Ways to Warm Your Hands
- You can insulate your hands in mittens or pockets which works by reducing heat loss.
- Another way you can warm you hands is by raising your overall body temperature by putting on a sweater or exercising.
- You can hold a warm drink or sit on your hands which transfers heat through conduction or direct contact.
- If you hold you hands over a register, the warm air blowing would be heating your hands through convection.
- And if you hold your hands over a radiator you would be heating your hands through, you guessed it radiations, which is the heat being transferred from one molecule to the next.

I like to use warm water so I wash my hands but if I am very cold, I take a hot bath. Heat transfer! Entropy?

That is a great way to warm up!
Entropy! Had to look that up : )
I also will wash my hands with warm water. I usually wear gloves if I am going out and it is really cold!
Washing hands – I do that one too!
I tuck my hands into my armpits. But I’m not that cold very often here in Perth.

I have heard that is the most effective way to warm hands!
I just hold a hot cup of coffee. Warm and energizing. =)

Laying is the way to go! I like blankets too!
Between your science and bird posts, I have to wonder if you were a teacher in a past life, Ann! Your kids are lucky to have a mom like you to expose them to all this interesting stuff!

Maybe! Thanks Tiffanie!
I am partial to wearing gloves to keep my hands cozy and warm. I like the idea of just carrying around a hot mug of something delicious everywhere, though. Wouldn’t it be cool if we could start a fire by rubbing our hands together?

I like to warm my hands with a cup of tea
