Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. As body temperatures escalate without effective heat release, one might face dehydration threats.
