Note: The heat index, also known as 'feels like' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
