Cold water is a strong stressor for the heart and lungs. If you have heart disease, an arrhythmia, high or low blood pressure, circulation problems, diabetes or another medical condition, take medication, or are pregnant, check with your clinician first. Never plunge alone or after alcohol, and get out right away if you feel weak, dizzy or unable to control your hands and limbs. Warm up gradually afterward. Children should only use it with close adult supervision.
Research
What the research explores
Stress, sleep and wellbeing
A 2025 review of 11 studies with more than 3,000 participants found cold-water immersion may lower stress, improve sleep quality and support quality of life, with some effects changing over time. Read the review
A natural alertness response
Immersion in cold water triggers a measurable rise in noradrenaline, a hormone involved in alertness and focus. Read the study
Recovery and soreness
Reviews of cold-water immersion after hard exercise report lower perceived muscle soreness and better perceived recovery. Read the review
Recovery isn't the same as adaptation. Cold exposure right after strength training may blunt some of the muscle-building response, so if muscle growth is your goal, schedule cold sessions apart from lifting. Read the study
