Note: The heat index, also known as 'real feel' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity.

Heat index values are especially crucial for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
