Relative Humidity And Comfort

Although relative humidity is an important factor for thermal comfort humans are more sensitive to variations in temperature than they are to changes in relative humidity.

Relative humidity and comfort. According to the environmental protection agency indoor relative humidity should be kept below 60. For humans relative humidity below 25 feels uncomfortable dry. High relative humidity reduces people s ability.

Below 30 can result in unpleasantly dry conditions leading to skin and eye irritation. Meaning high or low relative humidity can be uncomfortable. Human comfort requires the relative humidity to be in the range 25 60 rh.

Given that air at low relative humidity has a much better capacity to absorb water vapour it makes sense a person exposed to 35 degree celsius temperatures and 25 per cent relative humidity as in a melbourne summer will feel more comfortable than someone exposed to 35 degree temperatures and 60 per cent relative humidity a darwin summer. This is an easy data point to access for forecasting fire danger regardless of the. Ideally between 30 and 50.

What s the ideal relative humidity level for comfort. Relative humidity has a small effect on thermal comfort outdoors when air temperatures are low a slightly more pronounced effect at moderate air temperatures and a much stronger influence at higher air temperatures. Typically with higher winds and relative humidity lower than 25 percent you are nearing critical fire danger.

Humidity is a factor in thermal comfort. Above 60 and the air will start to turn swampy.
