Heat index values are extremely vital to babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
