Heat index

Know that the heat index computations account for shaded terrains and slight winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important 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.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
