Note: The heat index, also known as 'feels like' or 'real feel', comes about by integrating the temperature readings with the humidity levels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. 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 particularly relevant to 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.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
