Pre Cooling Before Hot Session
Pre cooling before a hot session uses cold fluids or towels to lower starting core temperature—helpful for races and hard heat workouts when hydrated.
Pre cooling before a hot session lowers starting core temperature with cold drinks, ice slushies, cool towels, or brief cold showers—buying minutes of capacity before heat accumulation wins. It is a performance and safety tactic for races and hard workouts, not daily dependency.
Pair with hydration and sodium; avoid shivering so hard you waste glycogen.
Common questions
-
Does pre-cooling replace heat acclimation?
No—it is a short-term buffer. Acclimation still improves sweat response and cardiovascular stability across a hot season.
