According to the Environmental Protection Agency, the ideal indoor humidity level should be between 30 – 60%. It’s optimal for overall wellness and the efficient functioning of the respiratory immune system.

One of the biggest problems faced by people during winter is dry air. Low humidity contributes to the development of colds and flu. 60 to 80 percent of the human body is made up of water, which is why such an adverse bodily reaction to dry air. 

Maintaining normal house humidity in winter is crucial for improving health, particularly for people who suffer from asthma or allergies.

What is relative humidity?

Along with air temperature, relative humidity plays an important role in human thermal comfort

Along with air temperature, relative humidity plays an important role in human thermal comfort.

The relative humidity is a way of describing how much water vapor is there in the air, compared to how much there could be. When the temperature is warm, more water vapor can be in the air than when it is cold.

Why is the humidity low in winter?

Lorem ipsum dolor sit amet, consectetuer cold air is dry. The lower the temperature, the less water can exist in the vapor state. Using central heat during the winter can lower a building’s relative humidity levels. When cold outdoor air with little moisture is heated indoors, the air’s relative humidity can drop to about 20 percent.

Negative effects of dry air

Dry air can have a serious impact on the health and cause property damage, especially during winter. 

  • Dry air impairs the respiratory immune system’s ability to fight airborne viruses and germs and can cause such ailments as asthma, bronchitis, sinusitis, and nosebleeds.
  • Low humidity hurts the skin.
  • It could cause damage to wood furniture, walls, floors, and electronics.
  • Musical instruments can lose shape and tune.
  • Books and artwork can become wrinkled.
  • Low humidity indoors in winter contributes to higher utility costs – dry air feels colder, prompting to turn up the heat.

Reduced humidity linked to increased COVID-19 risk

Doctors and scientists agree that raising indoor humidity levels has a strong effect on the transmission of airborne diseases and may help to deactivate coronavirus particles. Relative humidity of 40–60% can help to contain the virus.

Fighting dry air

To achieve the ideal humidity level in the house during winter in Canada, one can purchase a humidifier

To achieve the ideal humidity level in the house during winter in Canada, one can purchase a humidifier. Be sure to clean it regularly – air filters must be routinely washed or replaced. Good humidity can significantly improve indoor air quality. The cold weather makes winter bad enough.

Dry air can add to the discomfort. Humidification gives people a simple means of maintaining correct humidity for a house in winter and combating seasonal respiratory infections. Find the chart explaining humidity ranges for people with respiratory issues at the website of the National Asthma Council Australia.

Proper humidity setting for winter

Proper humidity setting for winter reduces the risk of virus spread without causing negative effects. A humidifier is a key to enhancing comfort and setting the best indoor humidity level in winter. And it can help save energy to feel warmer.
