Dew point is a measure of the moisture content of air. Dew point of 65F means that water will begin to condense out of air at an actual temperature of 65F. Relationship between absolute humidity and dew point is not linear – a 80F dew point contains much more water than 65F. 

Dew point has an influence on sweating/efficiency of sweating. Higher dew points makes it more difficult for sweat to evaporate – and it’s the evaporation that cools humans off. High dew points are correlated with overheating and more heat stress.
