But what you wear makes all the difference.
The Health Services Center at the University of California, Berkley, suggests these guidelines:
- Most of your body heat escapes through the top of your head, so don a hat.
- A pair of gloves and athletic socks will keep your body's other extremities cozy.
- Instead of heavy jackets or sweaters, wear layers. This way you can shed them when you warm up.
- Wear loose clothing. It traps layers of air and gives good insulation.
- Ditch your damp or sweaty clothing as soon as you can. Because the moisture accelerates heat loss, you could freeze if you stay in your wet garb.
