Note: The heat index, also known as 'real feel' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation. Be careful! The Sun's UV radiation is accentuated by reflecting off sand and water.
