Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
