Be aware that heat index ratings are designed for shaded locations and minor breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
