Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.The standards for the heat index are set for locations in shade and under light breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.

Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children.
