Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
