Note: The heat index, also known as 'apparent temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. 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 babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Frequent reapplication of a broad-spectrum SPF 30+ sunscreen is vital every two hours or directly after a swim or an outdoor workout. Caution! Sand and water surfaces escalate the UV intensity from the Sun.
