Does Mold Affect Sleep Quality? How Living in a Mouldy Home Affects Your Sleep.

Mold is extremely prevalent in homes across the United States. According to a study by Berkely Lab, approximately 47% of houses in the United States have substantial levels of mold, with over 85% of commercial and office buildings found to have water damage predictive of mold.

We know that many houses have unhealthy levels of airborne mold where nothing is visible. Mold growth can be hidden or simply not visible to the naked eye. The percentage of homes with unhealthy levels of airborne mold is likely even higher. Mold is more than just an unsightly nuisance. Recent scientific studies have shed light on the profound impact mold can have on our health, particularly our sleep quality and mental well-being. If you've ever wondered about the potential risks of living in a mold contaminated home, this article will provide you with a comprehensive overview based on the latest research.

Mold and Sleep Disruption

Several studies have directly linked mold exposure to sleep disturbances. For instance, research by C. Tiesler et al. (2014) suggests that visible mold or dampness at home might negatively influence sleep in children¹. Another study by C. Janson et al. (2005) indicates that avoiding dampness in building constructions and improving ventilation in homes has a positive effect on sleep quality². These findings underscore the importance of maintaining a mold-free environment for optimal sleep. Below we examine some of the specific health conditions that can affect sleep quality.

Mold's Impact on Respiratory Health

Mold exposure doesn't just affect sleep; it has broader health implications. D. Norbäck et al. (2011) found that dampness and indoor mold growth is a risk factor for lung function decline³. Similarly, M. Simoni et al. (2005) highlighted that respiratory disorders like wheeze and asthma can often be traced back to home mold/dampness exposure⁶. These respiratory issues can indirectly affect sleep quality, leading to restless nights and daytime fatigue. There's a very well established link in current medicine between quality of sleep and insomnia symptoms or sleep problems. There are sleep clinics up and down the country that help people understand why they're experiencing disturbed sleep and often the reason is one of an array of breathing issues. They typically stop short of diagnosing the root cause of the breathing issue if it's not a direct result of physiological changes like excess weight gain.

Mental Health and Mold Exposure

The relationship between exposure to mold and mental health is a growing area of concern. A study by C. Harding et al. (2015) revealed that even exposure to the mold skeleton can cause brain inflammation and cognitive deficits⁴. Furthermore, E. Shenassa et al. (2007) found a connection between dampness, mold, and depression, mediated by the perception of control over one's home and physical health⁵. This suggests that mold can have both direct and indirect effects on our mental well-being, further influencing our sleep patterns. There's already a strong body of academic research linking depression to trouble sleeping.

Children and Mold Exposure

Children, due to their developing immune systems, can be particularly vulnerable to mold exposure. C. Tischer and J. Heinrich (2013) emphasized that mold and microbial agents might impact broader aspects of children's health, including behavior and cognitive development⁷. Protecting our young ones from mold exposure becomes paramount when considering these potential health risks. As a child's biological systems are still developing, it's important to eliminate mold as a contaminant from the environment they spend the most time in. 

The Role of Professional Mold Remediation

While the health risks associated with mold are evident, it's essential to approach mold remediation with caution. Treating mold personally can be dangerous, as improper handling can exacerbate the problem and pose additional health risks. Professional mold remediation companies play a crucial role in safely decontaminating homes and restoring healthy living conditions. Their expertise ensures that mold is effectively removed, reducing the health risks associated with its presence¹¹.

Conclusion

Living in a mold contaminated home poses significant health risks, from sleep disturbances to respiratory issues and mental health challenges. While the importance of a mold-free environment is clear, it's equally crucial to approach mold remediation with the expertise it demands. By understanding the risks and seeking professional assistance when needed, we can ensure a healthier living environment for ourselves and our loved ones.
