Note: The heat index, also known as 'feels like' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
