Note: The heat index, also known as 'real feel' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Use protective steps and abide by sun safety guidelines. Safeguarding against skin and eye harm is necessary. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
