Be aware that heat index ratings are designed for shaded locations and minor breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
