Note: The heat index, also known as 'real feel' or 'feels like', unifies temperature and humidity readings to offer a comprehensive feel of warmth. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
