Additional factors like wind, pregnancy, differences in body mass, height, and shape, and activity influence one's weather impression.

Heat index values are especially crucial for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it is vital to remain hydrated, particularly during prolonged physical activities.

High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated.
