Long-term activity may induce heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
