Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. 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.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation.

As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
