Which strategy helps in preventing conductive heat loss in infants?

The strategy that effectively prevents conductive heat loss in infants is ensuring that surfaces in contact with them are prewarmed. Conductive heat loss occurs when an infant's body heat is transferred to cooler surfaces they come into contact with, such as a bed or changing table. By prewarming these surfaces, the risk of heat loss is minimized, as the temperature difference between the infant's body and the surface is reduced. This helps maintain the infant's body temperature, providing a more stable thermal environment, which is especially critical for newborns who have a limited ability to regulate their own body temperature.

Other strategies like using thermal shades, increasing room humidity, or adding layers of clothing do not directly target conductive heat loss. While they may contribute to overall warmth and comfort, they do not specifically address the issue of heat loss through contact with cold surfaces.
