May's heat index is evaluated at a hot 86°F (30°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Realize that the values for the heat index are set for shaded places and light winds. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
