Observations indicate that the heat index values are for shady locations with light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.Note
: The heat index, also known as 'real feel' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. 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 essentially critical for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Put into action all crucial precautions. Defense against sun damage is a must. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Even under cloud cover, use sunscreen with at least an SPF 30 generously and reapply frequently post every swim or outdoor exercise.
