Note: The heat index, also known as 'real feel' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
