If exposure and activity persist, fatigue could ensue, possibly leading to heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are quite important for babies and toddlers.
