Excerpt from The Hahnemannian Monthly, Vol. 54: January to December, 1919 The main methods of heat loss through the skin are by convection, radiation and evaporation. The heat loss through the lungs is by evaporation. The heat loss by convection de creases as the temperature of the air increases, falling: from an estimated 425 b.t.u. Per hour at 56 Degrees F. (with 56 per cent. Humidity to zero per hour when the air is at blood heat (with 56 per cent. Humidity).37 On the other hand, the heat loss by evaporation increases with increasing air temperature, rising from an estimated value of 50 per hour at 56 Degrees F. With 56 per cent. Humidity) to 400 B t.u. Per hour when the air is at blood heat (with 56 per cent. Humidity).37 The heat losses by radiation are but slightly known, but are held to de crease with rise of air temperature.
