Newborns are at higher risk for heat loss because?

• A. Their skin is thicker than adults
• B. Their skin is 40-60% thinner than adults
• C. They have more body fat
• D. They produce more heat

Answer: (B)

Newborns lose heat more quickly because their skin is thinner than an adult’s, which lets heat escape to the surrounding environment more readily. A thinner, more permeable skin barrier increases heat loss through evaporation and conduction. In addition, newborns have a larger surface area relative to their body weight and less insulating fat, so a greater portion of their body heat is exposed and not well retained. This combination makes maintaining warmth more challenging for newborns, highlighting the importance of keeping them dry, properly clothed, and in a warm environment.
