If alone after the initial gasp subsides, what conservation posture should be adopted?
Answer
HELP (Heat Escape Lessening Posture)
Once the initial Cold Shock phase ends (after about 3 minutes) and the gasp reflex ceases, the goal shifts from airway control to energy conservation to delay systemic cooling and incapacitation. If a person is in the water alone, they should adopt the HELP (Heat Escape Lessening Posture). This specific posture involves crossing the arms tightly over the chest and drawing the knees up towards the chest. This arrangement is crucial because it significantly reduces the surface area exposed to heat loss in the areas where the body loses heat most rapidly, specifically the groin, neck, and armpits, thereby maximizing energy conservation.
