Note: The heat index, also known as 'feels like' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
