Symptoms of Black Mold

Exposure to black mold can lead to various symptoms, which depend on an individual’s sensitivity, and the duration and severity of their exposure.

Symptoms of black mold exposure can include a stuffy or runny nose, coughing, wheezing, and eye irritation. In some cases, exposure to black mold can also cause skin rashes, headaches, and fatigue.

While these symptoms may be mild in some individuals, they can be more severe in others, particularly those with allergies or asthma. In rare cases, prolonged exposure to black mold can lead to more serious health problems.

Identifying black mold

Identifying Black Mold

Identifying black mold can be difficult because it looks similar to other types of mold. However, there are some signs that can help distinguish it from other molds.


One of the most noticeable signs of black mold is its color. As the name suggests, black mold is typically black or dark green in color.


It can also have a slimy texture and a musty odor. If you notice a musty smell in an area of your home, it may be a sign of black mold. Another way to identify black mold is by its growth pattern.


Black mold tends to grow in a circular pattern and can cover large areas if left untreated. It can also grow on porous surfaces such as drywall and wood, which can make it difficult to remove.

If you suspect that you have black mold in your home, it is important to have it properly identified and removed by a professional.

Common symptoms of black mold exposure

Exposure to black mold can cause a range of symptoms that vary in severity depending on the individual’s sensitivity to the mold and the amount of exposure. Here are the most common symptoms of black mold exposure:

  • Sneezing
  • Coughing
  • Nasal congestion
  • Postnasal drip
  • Red eyes
  • Skin rash
  • Sore throat

These symptoms may be more severe if you have a true mold allergy, which is a reaction triggered by your immune system. In such cases, you may experience:

  • Coughing
  • Wheezing
  • Nose stuffiness
  • Red or itchy eyes
  • Skin rash
  • Sore throat

Particular molds may also cause an asthma attack in people who have asthma, a chronic respiratory condition. Symptoms of an asthma attack may include:

  • Wheezing
  • Shortness of breath (dyspnea)
  • Dry cough and chest tightness

It is important to note that not everyone exposed to black mold will experience symptoms. Some people may be more sensitive than others, while others may not be affected at all.

Respiratory symptoms

Black mold exposure can cause respiratory symptoms, which can vary from mild to severe. These symptoms can be caused by inhaling black mold spores or by having an allergic reaction to them. Respiratory symptoms may include:

Coughing and wheezing

Coughing and Wheezing

Coughing and wheezing are common respiratory symptoms caused by black mold exposure. Coughing is a reflex action that helps to clear the airways of mucus, irritants, and foreign particles.

Wheezing is a high-pitched whistling sound that is produced when air flows through narrowed airways. It can be a sign of a serious respiratory condition, such as asthma or bronchitis.

Breathing difficulties

Breathing Difficulties

Black mold exposure can cause breathing difficulties, especially in people with pre-existing respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD).

Breathing difficulties can range from mild to severe and can include shortness of breath, chest tightness, and difficulty breathing. In severe cases, black mold exposure can cause respiratory failure, which can be life-threatening.

It is important to note that respiratory symptoms caused by black mold exposure can be similar to those caused by other respiratory conditions.

Therefore, it is important to seek medical attention if you experience any respiratory symptoms. A healthcare provider can diagnose black mold exposure and help to manage your symptoms.

Neurological symptoms

Black mold exposure can lead to various neurological symptoms. These symptoms can range from mild to severe and can affect different parts of the nervous system.

Here are some of the neurological symptoms associated with black mold exposure.



Headaches are a common symptom of black mold exposure. These headaches are usually described as a dull, persistent ache that is often accompanied by pressure in the head.

These headaches can be caused by the mycotoxins produced by black mold, which can cause inflammation in the brain.
