Note: The heat index, also known as 'real feel' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
