One should consider that heat index numbers are for shaded settings and light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. 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 of high significance for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
