Note: The heat index, also known as 'apparent temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
