Why are children less efficient at thermoregulation than adults?
a. children's sweat rate is much higher than adult's
b. children's sweat rate is much lower than adult's
c. children have comparably smaller surface area than adults which allows greater heat exchange
d. children's ratio of surface area to body mass causes slower heat loss in the cold
Answer: b. children's sweat rate is much lower than adult's
Children are less efficient at thermoregulation for several reasons. to include they have a much slower sweat rate than adults. Their body surface relative to body mass is greater than an adults, which allows a greater rate of heat exchange and risk of extreme temperature disorders or injury.
