Note: The heat index, also known as 'feels like' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
