Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
