If you fall into frigid water, what should you do with your knees?

Pulling your knees up to your chest in frigid water is a critical survival technique known as the "heat escape lessening position" (HELP). This position minimizes heat loss by protecting vital organs and reducing the surface area exposed to cold water. When the knees are drawn up, the body's core temperature is better preserved, which is vital for survival in cold conditions.

This position creates a more compact shape, allowing your body to retain warmth and reducing the risk of hypothermia. Keeping the knees close to the chest also helps to conserve energy, as it reduces the amount of movement needed to stay afloat. In contrast, other positions could increase exposure to cold water and hasten the loss of body heat, making them less effective for survival.
