Note: The heat index, also known as 'real feel' or 'feels like', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
