Heat index data is primarily for areas with shade and subjected to light winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
