Note: The heat index, also known as 'real feel' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. 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.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
