Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
