5 Interesting Studies And Stats About Mold

Are you aware of the prevalence of mold in your area? Perhaps these statistics will provide some insight.

Regardless of where you reside, everybody needs to decrease the amount of atmospheric mold they’re inhaling.

If there’s a musty odor coming from your home, it’s probably mold and if you actually notice the fungus in your office or residence, then you have a problem.

According to W.H.O., indoor dampness affects an estimate of 10-50% of indoor environs in North America, India, Japan, and Australia. This statistic implies that mold could be a very prevalent matter in various locations worldwide.

If you’re curious about mold-related studies and statistics, check this out.

  1. Study on Mold and Depression

A groundbreaking study published in 2007 by a team at Brown University found a link between depression and mold. The team led by the university’s epidemiologist, Edmond Shenassa, drew its findings from the data analysis of almost 6,000 European adults.

This study linked mold exposure to symptoms such as fatigue, asthma, and allergies. According to the study, the helpless and stressful feelings produced by these symptoms also generate psychological symptoms, particularly depression.

While the study wasn’t aimed at determining whether mold is the direct source of depression, findings from the study revealed two possible causes of the link between depression and household mold.

One of the indicated factors was a supposed lack of control over the housing setting while the other was mold-related health issues, such as fatigue and wheezing.

Mold releases mycotoxins, which can result in brain tissue inflammation. This could in turn affect brain function, resulting in various cognitive, mood, and behavioral problems such as depression.

  1. Worst American Cities for Mold Allergies

According to a 2011 report, these are some of the worst cities to live in if you suffer from mold allergies.


The city emerged the worst and had the highest rate of mold sensitization-21%. The report also revealed that 21% exhibited an allergic mold reaction. The city also ranked high in the allergy sensitization index.


According to the report, this city ranked second with a sensitization rate of 19% and an overall sensitization index of 695. In 2006, the Asthma and Allergies Foundation of America ranked it as one of the most challenging metropolitan area for asthmatic people.

  1. Studies linking Mold to Asthma

According to statistics, about 2.5 million Canadians are asthmatic. Data further reveals that approximately 275,000 Albertans or 6% of the populations suffers from the same condition. The chronic inflammatory illness can cause wheezing, chest tightness, and shortness of breath.

A Finnish study conducted in 2001 discovered a link between the fungus and asthma. The researchers at Turku University released findings, which suggested that dampness in the home “maintains” asthmatic symptoms and may boost someone’s susceptibility to colds and other respiratory infections.

Another Cincinnati study aimed to reveal a similar link. The researchers based their findings on the analysis of about 300 children ranging from one 1-7.

The 2012 study discovered that three mold species: Aspergillus unguis, Aspergillus ochraceus, and Penicillium were harmful to children and caused asthmatic symptoms in them.

  1. Study Linking Mold to Sinusitis

About 5% of Canadians suffer from sinusitis. Acute sinusitis originates from bacterial infections, which typically last a month or less. Researchers from The Mayo Clinic claim that mold could cause the condition.

According to doctors at the Clinic, fungus causes chronic sinusitis, which is an immune reaction. They derived their findings from a study of 210 patients with the condition. The researchers also found that 96% of the patients had fungus in the collected samples.

  1. Link between Mold and Sick Building Syndrome (SBS)

A 1984 WHO report on SBS suggested that up to 30% of remodeled and new buildings globally might have a link to SBS symptoms.

Mold-related complaints may include hypersensitivity and neurotoxicity. Research on sick buildings reveals that building-related symptoms have a link to building characteristics including dampness.

Furthermore, causes include mold and volatile organic compounds. According to a Swedish study, SBS has devastating potential. According to its findings, 25% of the participants were obtaining disability pensions while 25% were on the sick list.
