Note: The heat index, also known as 'feels like' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
