You may be used to using "relative humidity" to determine how comfortable that is, but it's just that; relative.

A new study suggests that relative humidity levels in the office setting can have an impact on stress and potentially even sleep quality.

First up is the heat index. Heat index uses the air temperature and the relative humidity to find the level of discomfort a person may experience on a hot and humid day.

For all the uses of relative humidity, dewpoint may be the better, quicker way to assess the comfort factor of the air. Dewpoint is a more direct measure of how much moisture is in the air.

What humidity is comfortable? The American National Standards Institute recommends maintaining a relative humidity level of between 30% and 60% in habitable spaces.

This results in a heat index value of around 108 degrees. If you were just relying on the relative humidity, you might think it's not all that humid outside.

Relative humidity is a much more variable, much less reliable gauge of comfort because it is, well, relative to temperature. When the air's temperature matches its dew point temperature, relative ...

A health study from the World Health Organization cites absolute humidity, asthma, and dust mites, but this does not address relative humidity and comfort. “We changed design condition, raised ...

Most people understand relative humidity, but the dew point is a much better measure of how humid it really feels.
