Note: The heat index, also known as 'feels like' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences.

Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.
