Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. 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 can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are largely significant for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
