Note: The heat index, also known as 'real feel' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
