Widely circulated representation of Hayward’s 6 passive cooling model. Heavy curve is same as dashed curve in Fig. 1. Shaded band is estimated area of uncertainty (see text).
Grahic Jump Location
Proposed survival model. Curves were computed from Eq. (3) for 6 mm increments of body fat=2 mm neoprene foam, any combination of which can be combined to give total whole-body insulation. Although intended for passive survival, curves also provide reasonable estimates for onset of hypothermia among expert swimmers.
