Theory primer (from https://derangedphysiology.com/main/cicm-primary-exam/thermo...):

> The total heat transfer of a human is the same as the metabolic heat production, and is approximately 100 watts, or 400 kJ/hr, or 60-70 kcal/hr at rest. It occurs by:

  >  Radiation (50%)
  >  Convection (30%)
  >  Evaporation (20%)
  >  Conduction (usually 0%)
(Radiation and convection can either cool or heat you depending on the environment)
