Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
