Note: The heat index, also known as 'feels like' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. 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 primarily vital for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
