But if you live in a basement, are you at risk of oxygen depletion? Even though you won’t be lacking in air, if your basement has unpurified air, oxygen deficit may make you experience a level of discomfort sufficient to disrupt your sleep. 

This article discusses your risk of oxygen deficiency and how to prevent it.

Can a damp basement cause health problems?

A common concern of homeowners is that their basements might have too much moisture.

Since basement air is usually stagnant and humid, it can be a breeding ground for harmful mold, bacteria, and viruses.

Immune system complications and respiratory issues, such as asthma and chronic sinusitis, are believed to be exacerbated by living in poorly ventilated areas.

With their tight clusters of spaces, basements usually have low levels of sunlight and fresh air, which can cause a build-up of airborne pollutants and allergens.

Other factors that can affect the quantity of oxygen include:

  • cooking
  • open/naked flames
  • tobacco smoking
  • woodworking
  • paint
  • the presence of moisture and mold
  • the presence of garbage
