Health Problems That Mold Can Cause (CDC Data Summarized & Simplified)

by Brandon J. Faust

When it comes to mold, you may be well aware of the unsightly appearance and musty smell it can bring to your home. But have you ever considered the health problems that the CDC reports mold can cause? In this article, we will discuss the potential health issues that may arise due to mold exposure and how to keep yourself protected.

Mold, a type of fungi, can grow both indoors and outdoors, in virtually any area with moisture, warmth, and oxygen. While most commonly found in damp or humid environments, mold can be a persistent issue for homeowners and renters alike. According to the CDC, mold exposure can lead to a variety of health problems, particularly for those with allergies, asthma, or weakened immune systems.

Understanding the risks associated with mold growth is essential for the maintenance of a healthy living environment. By keeping informed about mold-related health concerns and taking preventative measures, you can safeguard your home and well-being from its potentially harmful effects. Read on to learn about the specific health problems the CDC warns about when dealing with mold.

Health Problems Associated with Mold Exposure

Mold exposure can lead to various health problems, which the Center for Disease Control and Prevention (CDC) has identified. In this section, you will learn about the three main health issues mold can cause: allergic reactions, asthma complications, and respiratory infections.

Allergic Reactions

When exposed to mold, you may experience allergic reactions similar to those caused by other allergens, such as pollen. Symptoms may include:

  • Sneezing
  • Runny or stuffy nose
  • Itchy or watery eyes
  • Rash or hives

These reactions may vary in severity, from mild discomfort to severe allergic reactions that can impair your daily activities.

Asthma Complications

If you have asthma, mold exposure can exacerbate the condition, leading to increased asthma attacks and symptoms. These symptoms can include:

  • Wheezing
  • Coughing
  • Chest tightness
  • Shortness of breath

Mold exposure can be especially problematic for children with asthma, as their respiratory systems are still developing.

Respiratory Infections

Besides allergic reactions and asthma complications, mold can also cause respiratory infections, particularly in people with weakened immune systems or pre-existing lung conditions. Inhaling mold spores can result in infections such as:

  • Aspergillosis
  • Mucormycosis

These infections can range from mild to severe and in rare cases, may become life-threatening if left untreated.

Risk Factors for Mold-Related Health Issues

The Centers for Disease Control and Prevention (CDC) lists several health problems that mold can cause. In order to understand the risk factors for these mold-related health issues, it’s important to consider both predisposing factors and environmental conditions that contribute to mold growth and exposure.

Predisposing Factors

Some individuals are more susceptible to mold-related health issues due to their personal predisposing factors, such as:

  • Allergies or asthma
  • Weakened immune systems (e.g., from chemotherapy or HIV)
  • Chronic lung disease
  • Age (young children and the elderly are more vulnerable)

Keep in mind that it’s not only individuals with these predisposing factors who can experience health issues from mold exposure. However, those with predisposing factors may experience more severe or prolonged symptoms.

Environmental Conditions

Mold thrives in specific environmental conditions, and understanding these conditions can help you mitigate risks related to mold exposure. Mold grows in damp and humid environments with the following factors:

  • High humidity levels (above 60%)
  • Leaking pipes or roofs
  • Condensation on windows, walls, or pipes
  • Poor ventilation
  • Flooding or water damage

By addressing these environmental conditions, you can minimize mold growth and reduce the risk of mold-related health issues in your home or workplace.

In order to protect your health and property from the negative effects of mold, it is essential to take preventive measures. In this section, you will learn about the following strategies to prevent and control mold growth in your indoor environment:

Proper Ventilation

Good in-home air circulation is vital to preventing mold growth. Make sure that kitchens, bathrooms, and laundry rooms are well ventilated:

  • Use exhaust fans when cooking or bathing.
  • Open windows when weather permits.
  • Ensure air vents and registers are clean and not blocked by furniture or debris.

Humidity Control

Controlling indoor humidity levels helps discourage mold growth. Aim to maintain a humidity level of about 30-50% in your home:

  • Use a dehumidifier to reduce moisture in damp areas.
  • Monitor indoor humidity levels with a hygrometer.
  • Try not to overwater indoor plants, as this can increase humidity levels.

Rapid Repairs

Fixing water leaks and addressing other moisture problems promptly is essential in preventing mold growth:

  • Regularly inspect your home for water leaks and repair them immediately.
  • Check for condensation, especially around windows and doors, and address any issues that might cause it.
  • Ensure your roofing and gutters are well-maintained and free of debris.


Cleaning regularly and addressing mold as soon as it appears can help to prevent it from spreading:

  • Wipe up spills and clean wet areas as soon as possible.
  • Regularly clean and inspect areas that are prone to mold growth, such as bathrooms and basements.
  • Use mold-resistant cleaning products.

By implementing these prevention and control measures, you can create a healthier living environment and minimize the risk of mold-related health issues.

Seeking Medical Attention for Mold-Related Symptoms

Providing as much information as possible about the circumstances of your exposure can help your healthcare provider determine the best course of action for your treatment.

Some symptoms that may warrant a visit to your healthcare provider include:

  • Respiratory issues such as wheezing, shortness of breath, or chest tightness
  • Nasal congestion or sinus issues
  • Eye irritation, including redness, itching, or watering
