Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature.

Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
