Heat index

It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
