What happens if you sleep with black mold?

Sleep is an essential part of our daily lives, allowing our bodies and minds to rest and rejuvenate. However, the quality of our sleep depends on various factors, including the environment in which we sleep. One potential danger that can greatly impact our health and sleep quality is the presence of black mold. In this blog post, we will explore the potential dangers of sleeping with black mold, the health risks associated with exposure, its impact on sleep quality, steps to take if you suspect mold exposure, and preventive measures to minimize black mold exposure in your sleeping areas.

Health risks associated with black mold exposure

Black mold, also known as Stachybotrys chartarum, is a type of mold that produces mycotoxins, which can be harmful to human health. Breathing in a lot of these mold spores can lead to a variety of health conditions, particularly for your lungs. Here are some of the respiratory issues that can arise from black mold exposure:

Hay fever

Hay fever, also known as allergic rhinitis, is an allergic reaction to allergens, including mold spores. Symptoms may include sneezing, a runny or stuffy nose, itchy eyes, and throat irritation. Sleeping in an environment contaminated with black mold can trigger hay fever symptoms and disrupt your sleep.

Sleep apnea

Sleep apnea is a sleep disorder characterized by pauses in breathing or shallow breaths during sleep. Exposure to black mold can irritate the airways and contribute to the development or worsening of sleep apnea symptoms. This can lead to fragmented sleep and daytime sleepiness.

Severe coughing

Inhaling black mold spores can irritate the respiratory system, leading to severe coughing. This persistent cough can disrupt your sleep and affect your overall well-being.


Black mold exposure has been linked to the development or worsening of asthma symptoms. Asthma is a chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to breathing difficulties, wheezing, and coughing. Sleeping with black mold can trigger asthma attacks and make it harder to achieve a restful sleep.

Pulmonary infections

Exposure to black mold can weaken the immune system and make individuals more susceptible to respiratory infections. This includes pneumonia, bronchitis, and other pulmonary conditions. These infections can cause coughing, chest pain, difficulty breathing, and fever, all of which can disrupt sleep and impact overall health.

In addition to respiratory issues, black mold exposure can also cause allergic reactions, such as:

Skin rashes

Contact with black mold can lead to skin rashes and hives. These allergic reactions can be itchy, uncomfortable, and can interfere with sleep.

Itchy eyes

Black mold spores can irritate the eyes, causing redness, itching, and watering. Itchy eyes can make it difficult to sleep peacefully.


Sneezing is a common allergic reaction to black mold spores. It can disrupt sleep and leave you feeling tired and irritated.

Runny nose

Black mold can trigger a runny nose or nasal congestion. This can make breathing difficult, especially during sleep, and impact the quality of rest.

Black mold and its impact on sleep quality

The presence of black mold in your sleeping environment can significantly impact the quality of your sleep. Here are some ways in which black mold can affect your sleep:

Disrupting sleep patterns

The presence of black mold can cause discomfort, allergies, and respiratory issues that interrupt your sleep patterns. Waking up frequently during the night can prevent you from entering deep, restorative sleep cycles and leave you feeling groggy and unrested.

Fatigue and reduced energy levels

Poor sleep quality due to black mold exposure can lead to daytime fatigue and reduced energy levels. It can be challenging to focus and perform daily tasks when you are constantly tired.

Increased likelihood of insomnia

The discomfort and respiratory issues caused by black mold exposure can contribute to insomnia. Insomnia is a sleep disorder characterized by difficulties falling asleep or staying asleep. The presence of black mold can make it challenging to relax and achieve a restful state necessary for sleep.

Steps to take if you suspect exposure to black mold

If you suspect exposure to black mold in your sleeping area or elsewhere in your home, it is essential to take immediate action. Here are some steps you can take:

Identify the presence of black mold

Perform a visual inspection in areas with high moisture or water damage, such as bathrooms, basements, or areas with known leaks. Look for visual signs of black mold, such as dark patches or discoloration. Additionally, pay attention to any musty odors that may indicate the presence of mold.

Seek professional help

Contact mold remediation specialists or professionals trained in mold removal if you suspect a significant black mold problem. They can assess the situation, conduct environmental testing and inspections, and recommend appropriate actions to mitigate the mold issue.

Addressing the mold issue in your living environment

If the mold issue is minor, you may be able to clean and remove visible mold yourself. However, it is essential to follow proper safety measures to protect yourself from exposure to mold spores. Additionally, it is crucial to address the root cause of the mold problem, such as fixing moisture issues or improving ventilation in affected areas.

Preventive measures to minimize black mold exposure

Preventing black mold growth is crucial for maintaining a safe and healthy sleeping environment. Here are some preventive measures you can take:

Regular cleaning and maintenance

Keep your sleeping area and the entire house clean. Regularly clean and dust surfaces to minimize the buildup of mold spores. Pay attention to areas with high moisture, such as bathrooms and kitchens.

Proper ventilation

Promote airflow and ventilation in your home to prevent moisture buildup. Use exhaust fans in bathrooms and kitchens, open windows when weather permits, and ensure proper ventilation in enclosed spaces.

Controlling humidity levels

Maintain optimal humidity levels in your home. Ideally, humidity levels should be below 50% to prevent mold growth. Use dehumidifiers in areas prone to excess moisture and avoid overwatering houseplants.

Immediate response to water leaks or moisture issues

Address water leaks and moisture issues promptly. Fix any leaks, repair damaged pipes, and dry out wet areas as soon as possible. Preventing water accumulation is crucial in preventing mold growth.


Sleeping with black mold can have severe health consequences and negatively impact sleep quality. The health risks associated with black mold exposure include respiratory issues, allergies, and sleep disorders. It is important to address and prevent black mold in sleeping areas to ensure a safe and healthy sleeping environment. Taking steps to identify and remove black mold, seeking professional help when necessary, and implementing preventive measures can help minimize the risk of mold exposure and promote restful sleep. Prioritize your sleep and create a mold-free sleeping space for optimal well-being.
