Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. As body temperatures escalate without effective heat release, one might face dehydration threats.
