Heat index data is primarily for areas with shade and subjected to light winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Taking safety measures is non-negotiable; skin and eyes can be swiftly affected if neglected. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes. Apply generously and frequently reapply a sunscreen with SPF 30 or more even on cloudy days, particularly after a swim or outdoor exercise. Notice! Sand and water reflections contribute to a stronger UV exposure.
