Can Black Mold Make You Depressed?

Black mold, also known as Stachybotrys chartarum or Stachybotrys atra, is a type of fungus that can grow indoors in damp and humid conditions. It is commonly found in areas with water damage, such as leaky roofs, poorly maintained air conditioning systems, and places with high humidity such as bathrooms and kitchens.

Exposure to black mold can cause a variety of health problems, including respiratory issues, allergies, and even depression. While mold itself does not cause depression, it can trigger an autoimmune response that causes inflammation in the brain, leading to symptoms associated with depression.

The Link Between Mold and Depression

According to a study published in the American Society for Microbiology, exposure to mold can trigger an immune response in the body, leading to the release of inflammatory cytokines in the brain. These cytokines can cause a range of symptoms, including fatigue, moodiness, and depression. Additionally, mold exposure can cause an increase in the stress hormone cortisol, which can also contribute to symptoms of depression.

Research conducted on animals has also suggested a link between mold exposure and depression. In one study, rats exposed to mold showed increased levels of anxiety and depressive-like behaviors compared to control groups.

The Symptoms of Depression Caused by Mold Exposure

The symptoms of depression caused by mold exposure can vary from person to person. Some common signs include:

  • Feelings of sadness, hopelessness, or worthlessness
  • Changes in appetite or weight
  • Difficulty sleeping or oversleeping
  • Decreased interest in activities previously enjoyed
  • Physical symptoms such as headaches and fatigue
  • Irritability, mood swings, or anxiety
  • Difficulty concentrating or making decisions
  • Thoughts of self-harm or suicide

If you are experiencing any of these symptoms, it is important to seek medical attention to determine the underlying cause.

Preventing Mold Growth

The best way to prevent mold growth is to control humidity and moisture in your home. Here are some simple steps you can take:

  • Fix leaks and water damage as soon as possible
  • Ensure proper ventilation in bathrooms, kitchens and other areas that produce moisture
  • Use a dehumidifier to reduce humidity levels indoors
  • Clean and dry any wet surfaces promptly
  • Regularly inspect and clean air conditioning, heating, and humidifier systems

Removing Mold Safely

If you suspect that you have mold growth in your home, it is important to address the problem immediately. Removing mold can be dangerous, and it is recommended that you hire a professional mold remediation specialist to remove the mold safely. Here are some important steps to take:

  • Avoid disturbing mold growth as much as possible, as this can release mold spores into the air
  • Wear protective gear such as gloves, goggles, and a mask to avoid inhaling mold spores or getting them on your skin
  • Use an effective cleaning solution to kill the mold, and avoid using bleach as it can actually worsen the problem
  • Use proper ventilation in the area, such as opening windows or using a fan, to prevent further exposure to mold spores
  • Dispose of any contaminated materials, such as carpet or drywall, safely and according to local regulations


While mold itself does not cause depression, exposure to black mold can trigger an immune response that causes inflammation in the brain, leading to symptoms associated with depression. If you suspect that you have mold growth in your home or are experiencing symptoms associated with mold exposure, it is important to seek medical attention and address the problem promptly to protect your health and wellbeing.


FAQs about Can Black Mold Make You Depressed

1. What is black mold and where can it be found?

Black mold, also known as Stachybotrys chartarum, is a type of toxic mold that produces toxic compounds called mycotoxins. It can be found in areas of high humidity and moisture such as bathrooms, kitchens, and basements. It can also grow in damp and water-damaged buildings.

2. Can exposure to black mold cause depression?

Research suggests that exposure to black mold can lead to psychological symptoms such as depression, anxiety, and irritability. This may be due to the mycotoxins produced by the mold, which can impair the nervous system and affect our brain chemistry. However, further research is needed to fully understand the link between black mold and depression.

3. What are the symptoms of black mold exposure?

Some of the symptoms of black mold exposure include respiratory problems, allergic reactions, irritation of the eyes, nose, and throat, fatigue, headaches, and memory problems. It is important to seek medical attention if you experience any of these symptoms, especially if you suspect that you have been exposed to black mold.
