Wool is a fascinating material because it’s one of a few that can regulate body temperature in the heat of summer and the dead of winter.
Most people know that wool sweaters, hats and blankets are a great choice for those cold winter months, but not many actually know why.
Here are three main reasons wool keeps you warm (and dry):
- Keratin: Keratin is a protein that’s found in all animal fur/hair. It helps regulate body temperature by creating an added barrier around the fibers of the wool (kind of like insulation in your home).
- Air pockets: Wool has tiny air pockets in the fibers that trap heat. When you move around (even in your sleep) you conduct heat, so that can help make you even warmer.
- Wicking power: Wool has the ability to wick away any moisture. It can also hold about 20% of the wool’s weight in water and still keep you dry because it’s naturally water resistant.
