Continuous activity may induce heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
