snowsuits, winter boots, hats, mittens and scarves.

Exposed skin can become frostbitten in as little as 30 seconds, always cover exposed skin especially when
the wind is a factor.
Keep moving
Try to limit the time sitting. Stand up and move around to allow circulation to reach better reach all body parts.
Blankets and portable seat/cushion
Sitting on cold pavement or concrete can increase the risk of hypothermia. Sitting on a blanket or portable
seat will limit the risk.
Drink fluids
