|Several large studies have reported that sleep problems are significantly more common in indoor mold exposed patients as compared to unexposed controls.|
A study of randomly selected 4,979 adults all over the USA reported that presence of moldy or musty odor was associated with significantly higher rate of sleep complaints vs adults not exposed to musty odor (OR 1.37, 95% CI 1.07-1.75) (Shiue 2015).
A study of 1,719 children in 4 German cities reported that visible mold or dampness was associated with significantly higher risk of all sleep problems (OR 1.77, 95% CI 1.21-2.60) and significant problems in sleeping through the night (2.52; 95% CI 1.27-5.00) (Tiesler, Thiering et al. 2015).
The mechanism by which mycotoxins affect sleep is not well known, however it could be due to the neurotoxic and endocrinotoxic (hormone disrupting) effects of many mycotoxins.
