Be advised, the heat index considers values for conditions in shade and with a light breeze. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
