What is a cold plunge?
A cold plunge is a tub of cold water, about 45°F, that you sit in for a short time. At Biohack the private room is yours for 15 minutes, and most people spend 3 to 6 minutes of it in the water.
The science
Water at about 45°F pulls heat from your body far faster than cold air, which sets off a quick rush of noradrenaline, the body's alertness chemical. A 2025 review of 11 studies found people felt less stressed about 12 hours after cold immersion.
Large reviews of dozens of studies found that cold water after hard exercise eased muscle soreness over the next day or two. One note from the research: if you're lifting to build muscle, some people wait a few hours after training before a cold plunge.
What does it feel like?
A sharp shock for the first few breaths, then it settles. Slow, steady breathing helps. Most people get out feeling reset and wide awake.
