Note: The heat index, also known as 'apparent temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity.

In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
