Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for 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.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
