Note: The heat index, also known as 'feels like' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth.

Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
