Continuous activity may induce heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
