Ice & Cold

Survive cold-water immersion

Surviving cold-water immersion means protecting your airway, controlling your breathing, and getting out or staying afloat until rescue. Use these actions after falling from a boat, entering cold water unexpectedly, or breaking through ice. Cold shock threatens first, cold incapacitation can soon prevent swimming or gripping, and hypothermia develops later—so prioritize breathing and flotation before conserving heat. Alcohol speeds heat loss and impairs judgment; never drink to 'warm up' in a cold-water emergency.

Topic summary

Key takeaways

Your mouth and nose stay clear of the water, and your breathing becomes controlled enough to call for help.
You use flotation or a secure support rather than exhausting yourself with unnecessary swimming.
During an ice-escape rehearsal, you stay horizontal and roll or crawl away before standing.
Your HELP position or huddle maintains a clear airway for everyone, and you can still signal for rescue.
Avoid: Trying to sprint-swim immediately wastes strength and disrupts breathing, so establish airway control and flotation before deciding whether to move.
Avoid: Removing clothing in the water sacrifices insulation and useful energy, so generally keep it on unless an item is snagged or prevents escape.

Awaiting qualified medical review. This first-aid lesson has not been reviewed by a medical professional. It does not replace medical care or formal wilderness first-aid training.

Safety: Do not deliberately enter cold water or go onto unsafe ice to practice; rescuers should reach or throw flotation from a secure position rather than enter the water. After escape, handle yourself or the casualty gently, shelter from wind, replace wet clothing when protected, insulate from the ground, and seek urgent medical help for breathing difficulty, confusion, marked drowsiness, or persistent cold symptoms.

Required tools

Properly fitted life jacket
Whistle attached to your life jacket
Ice picks carried where you can reach them
Waterproof means of calling for rescue
Throw line for a rescuer on safe ground

Required materials

Dry replacement clothing stored in a waterproof bag
Dry insulating layers or a blanket for after exit
Dry leaves or grass for insulation beneath you ashore if better insulation is unavailable

Step-by-step

Control your breathing for the first minute — cold shock triggers gasping and hyperventilation.
Why: Concentrating on controlled exhalations while keeping your airway clear reduces the risk of inhaling water; the first minute is a priority, not a guarantee that cold shock has ended.
Keep your head above water and avoid swimming hard; cold incapacitation can rob your strength in minutes.
Why: Use your life jacket or secure flotation to save effort, and swim only when a clearly reachable safe exit makes that a better choice than waiting.
If you fell through ice, kick horizontally and pull yourself onto solid ice, then roll away from the hole.
Why: Turn toward the direction you came from, use ice picks if available, and spread your weight as you slide out and roll or crawl back along your approach rather than standing near the weakened edge.
Assume the HELP position (Heat Escape Lessening Posture): cross arms over chest and draw knees up to reduce heat loss.
Why: Use this posture when a life jacket reliably keeps your mouth and nose clear; without adequate flotation, prioritize a position that lets you breathe rather than forcing your knees up.
If you're with others, huddle together to share body heat while waiting for rescue.
Why: With everyone supported by flotation, hold close with chests or sides together to reduce exposed surface area, keeping every face clear of the water and avoiding pushing anyone under.

Common mistakes

Trying to sprint-swim immediately wastes strength and disrupts breathing, so establish airway control and flotation before deciding whether to move.
Removing clothing in the water sacrifices insulation and useful energy, so generally keep it on unless an item is snagged or prevents escape.
Forcing the HELP position without adequate flotation can submerge your face, so abandon it if you cannot breathe freely.
Standing immediately after climbing out of an ice hole concentrates your weight, so roll or crawl away along your approach before considering standing.
Assuming you are safe as soon as you reach shore ignores continued cooling, so promptly seek shelter, dry insulation, and appropriate medical help.

Troubleshooting

If your breathing is uncontrolled, then keep your face clear using flotation or a supported floating position and focus on steady exhalations before attempting purposeful movement.
If the ice edge breaks as you climb, then keep yourself horizontal, work toward the approach side, and use ice picks or your forearms while kicking to slide onto ice that supports you.
If you cannot reach a safe exit, then stay with a floating boat or other substantial support, get as much of your body out of the water as possible, and signal for rescue.
If drawing your knees up or huddling makes your face dip underwater, then adjust or release the posture immediately and restore secure flotation.

Field practice drill

Practice for about ten minutes on dry ground with a partner and a fitted life jacket. Rehearse calming your breathing without breath-holding, choosing between a nearby safe exit and waiting with flotation, and signaling for help; then mime a horizontal ice escape and roll on a mat, followed by seated HELP and huddle positions. Repeat while your partner checks that you always prioritize a clear airway and avoid standing beside the imagined ice hole.

Indicators of success

Your mouth and nose stay clear of the water, and your breathing becomes controlled enough to call for help.
You use flotation or a secure support rather than exhausting yourself with unnecessary swimming.
During an ice-escape rehearsal, you stay horizontal and roll or crawl away before standing.
Your HELP position or huddle maintains a clear airway for everyone, and you can still signal for rescue.
