Note: The heat index, also known as 'feels like' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
