Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
