Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
