Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. 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. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful 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 physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
