Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather can be personal, changing with an individual's body mass, height, and 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 quite important for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
