Cold shock response
The first seconds bring an involuntary gasp and rapid breathing. In open water this is a drowning risk. Enter slowly, never jump, and stay within your depth.
Plunge safely
Cold exposure is not appropriate for everyone.
PLUNGD is an educational platform, not medical advice. If you have a health condition, are pregnant, take medication, or are unsure, seek qualified medical guidance before practising cold exposure.
Hypothermia
Cooling continues after you exit. Get dry, add layers, move gently. Do not rely on how you feel in the moment to judge how cold you are.
Cardiovascular stress
Cold immersion raises heart rate and blood pressure at the same time. If you have any heart, circulatory, blood pressure or seizure condition, speak with a qualified clinician first.
Never enter alone
Open water especially. Have someone present who can help you out and keep watch.
Alcohol and substances
Do not combine cold water with alcohol, recreational drugs, or anything that alters judgement or thermoregulation.
Breath-holding
Do not perform breath-hold or hyperventilation techniques in or near water. They can cause blackout without warning.
Outdoor hazards
Currents, tides, ice, cold snaps, submerged objects, access restrictions and water quality all change. Check local conditions each time.
More is not better
Longer and colder is not a goal. Short, regular exposures are the practice. Exit early whenever something feels wrong.
