Note: The heat index, also known as 'feels like' or 'real feel', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
