Why is the humidity low in winter? I’ve written about the reason for this before. Basically, it’s thatcold air is dry air. The lower the temperature, the less water can exist in the vapor state. You may have a highrelative humidity,* but the actual amount of water vapor in the a...

It has been shown that a relative humidity of 45% minimises virus activity. However, colder weather in the autumn and winter means that people turn the heating up. Heating draws moisture from the air so it is usually too dry and the humidity drops below 45%. The warmer the air is, the...
Whereas high levels of relative humidity can be uncomfortable to humans, low levels of humidity pose their own set of problems. In the summer we use air conditioners to reduce the air temperature and subsequently reduce the humidity levels in our homes. However, during the winter in colder ...
