Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
