Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
