Note: The heat index, also known as 'apparent temperature' or 'real feel', measures the perceived warmth when incorporating the humidity present in the air. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
