Note: The heat index, also known as 'real feel' or 'feels like', melds the effects of warmth and moisture to generate a feeling of heat. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. With direct sunlight, be aware that it might enhance the heat sensation, raising 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.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
