Prolonged activity might induce heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement.

By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters frequently overlook the need for breaks and fluid intake. Thirst is an advanced sign of dehydration - thereby highlighting the importance of keeping hydrated, particularly during long physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
