Description
Anna Karafová and colleagues measure how temperature responds to ice water in a 2026 study. Cold water immersion and winter swimming are pastimes with claimed health benefits, but the body's reaction depends on the person and dose, and details are thin. Ninety practitioners were divided by what they did: swimming two hundred or four hundred fifty meters, or immersing for five or nine minutes.
Tympanic temperature was measured around each exposure and body mass index calculated for everyone. Temperature shifted after exposure in nearly every subgroup, with the exception of the five-minute immersion in water below one degree, which produced no significant response. Among winter swimmers, leaner participants cooled more: body mass index correlated negatively with the temperature change in women and men. The largest swings appeared in people with three years of practice. The results suggest short dips barely register thermally, while body composition buffers heat loss.
