Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
