Heat index values are particularly relevant to babies and toddlers. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down.
