Your body will only be able to function and maintain it's homeostasis at a constant stable temperature of 98 degree's farenheit. It will usually only be able to take a min of 96 or a max of 102. Usually at hitting those max/min, the body will have begun to loose it's ability to mantain that temperature and it could then start beginning a downward spiral of Hypo- and hyper- Thermia, which is very dangerous.

Explanation:
Surfactants are highly surface active agents which are formed from a protein and lipid complex. It comprises of a hydrophobic and hydrophilic portion and its sole purpose is to control the tension at the air-liquid interface and thereby lower the surface tension. Surfactants are produced by the type II aveolar pneumocytes in the lungs.
Surfactants are needed in order to aid breathing and prevent straining oneself, it also prevents the lungs from collapsing during breathing, a term known as atelectasis.
