Cold stress

Cold, wet and wind together can cause frostbite and hypothermia, even on days that don't feel that cold.

Key points

• Dress in layers and keep a dry set of gloves and socks.
• Take warm-up breaks.
• Watch for shivering, numbness, pale skin and confusion.
• Wet clothes pull heat fast. Change them.
• Watch each other. People with hypothermia often don't notice.

Ask the crew

• Where is the warm-up spot today?
• Who needs extra gear?
