Cold Weather Safety

  • Dress in layers — base layer (moisture-wicking), middle layer (insulation), outer layer (wind/water protection)
  • Cover all exposed skin — heat loss is greatest from the head, neck, and hands
  • Stay dry — wet clothing dramatically increases heat loss
  • Limit strenuous activity in extreme cold to reduce stress on the heart
  • Never ignore shivering — it is the first sign your body is losing heat
