Note: The heat index, also known as 'real feel' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels.

Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
