Visual science, heat transferred (04/38) When you press your body up against another body outside in the cold, the rate of heat lost to the environment slows down because surface area exposed to the environment is less. If one is much warmer than the other, some of the heat lost from the warmer person will be harvested by the colder person until the two are roughly at an equal temperature, at that point heat losses from each person individually is lower, although this strategy only offers a practical improvement If two individuals are stranded inside an enclosed, windless environment and they lack cold-weather gear or If someone is pulled out of freezing water!
