When floating in cold water to conserve body heat, which posture is most effective?

Conserving body heat in cold water hinges on reducing heat loss. Movement stirs the surrounding water and creates convection currents that quickly carry away warmed water from your skin, so you lose heat faster. Staying as still as possible minimizes that heat transfer and also reduces energy use, helping your core temperature drop more slowly while you wait for rescue. In practice, aim to be as relaxed and motionless as you can while keeping your airway above the water. Since any unnecessary movement speeds heat loss, the still posture is the most effective option for staying warm.
