Note: The heat index, also known as 'felt air temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
