Note: The heat index, also known as 'feels like' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
