If one stays active during extended exposure, it might induce fatigue and result in heat cramps.It is essential to grasp that the heat index's numbers are for shade and light wind settings. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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.
