Note: The heat index, also known as 'real feel' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.
