Note: The heat index, also known as 'feels like' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. 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.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. 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. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
