A common way to measure dew point is to actually measure Relative Humidity (RH) and then, through mathematical equations, figure out the dew point. The ratio of the amount of moisture in the air at a specific temperature to the maximum amount that the air could hold at that temperature, expressed as a percentage.
Current Dew Point
Dew point is the temperature at which the moisture in the air begins to condense.
Example: Dew point is 60 degrees and the air temperature on the external skin of a pop can will be cool / cold. If the pop can is 55°F, any surface below 60° will be wet. (Any surface below the dew point will form condensation.)

Allergies are the most frequently reported chronic condition in children, limiting activities for more than 40% of them.
