Heat index values are extremely significant for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down.
