It is essential to grasp that the heat index's numbers are for shade and light wind settings. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature 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 extremely significant for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
