Summary

This study tested how a 15-minute ice pack on the back of the hand changes skin temperature and how cold or comfortable it feels. Thirty-nine healthy young men were randomly assigned to get either an ice pack or a room-temperature water pack. Researchers measured skin temperature and asked participants to rate their thermal sensation and comfort. The goal was to understand basic body responses to cold, not to treat any disease.
