Effects Of Humidity On Your Health

The majority of Canadians are unaware of the air they are breathing in their own homes, despite the fact that air quality is a significant factor that contributes to overall wellbeing and health. While we cannot control outdoor air quality, we can be more mindful of the air in our home, particularly the levels of indoor humidity. From the spread of diseases to respiratory concerns, dry air can be the unknown culprit of numerous health concerns for individuals. Dust, bacteria, allergens and viruses are constantly circulating in the air and humidity can play a key role in mitigating the impact of these microbes.

The Impact Of Low Humidity

Spreading Diseases

It’s important to note that healthy humidity levels must be between 40% to 60% RH. That means that homes that are below 40% RH are considered the ideal breeding ground for bacteria and viruses. Humans release water droplets referred to as aerosols and if an individual has an illness, the aerosols that they release contain harmful microbes. In normal humidified environments, the moisture in the air acts as a barrier, protecting other individuals from contracting the illness. As a result, the aerosols that are in the air will have no impact on others. However, if the air is dry, the harmful aerosols can move freely and spread, which can lead to other individuals getting infected or becoming ill. Thus, individuals breathing dry air have a higher risk of contracting airborne diseases.

Respiratory Issues

Dry air can be a breeding ground for mould, mites, mildew and allergens, which can lead to respiratory issues such as asthma, bronchitis and sinusitis. Individuals who struggle with asthma or other respiratory illnesses will experience intensified symptoms at home due to dry air conditions. 


Even further, low humidity can lead to dehydration, which can cause dry and irritated skin, dry eyes and nosebleeds. Individuals who suffer from eczema or acne will experience more frequent flare-ups due to dry air. Dry eyes can cause eye soreness, blurred vision and an increased risk of eye infections. 

The Importance Of Humidification

There are numerous benefits to balanced humidity levels in your home. Proper humidification can significantly decrease the chances of diseases and viruses circulating in your home. This is particularly important for families with young children and seniors. If a family member or loved one already suffers from a respiratory condition such as Asthma, then maintaining humidity levels is an essential step that will increase their comfort levels and alleviate some of their symptoms. 

Maintaining the appropriate relative humidity levels in your home will lead to a safer, healthier and more comfortable home. In the winter months, cold air that enters your home is heated, which decreases the humidity levels even further. In the summer, air conditioners can also remove moisture from the air. The key is to maintain a healthy relative humidity level in your home throughout all seasons. By doing so, your quality of life, level of comfort and wellbeing will drastically change!
