Note: The heat index, also known as 'real feel' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. 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. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
