Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion.

Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat.
