Note: The heat index, also known as 'feels like' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
