April's mean heat index is estimated at a hot 86°F (30°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. 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 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
