Heat index values are extremely significant for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
