Heat index

Observations indicate that the heat index values are for shady locations with light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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 body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
