It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
