Mould can cause a range of health issues, particularly for people who are sensitive or allergic to it. The health effects depend on the type of mould, the amount of exposure, and the individual’s health condition. Some common health problems linked to mould exposure include:

1. Respiratory Issues

• Allergic Reactions: Common symptoms include sneezing, coughing, wheezing, nasal congestion, and itchy eyes. People with allergies may be more sensitive to mould.
• Asthma: Mould can trigger asthma attacks in individuals who already have asthma. It can also worsen symptoms in those with pre-existing respiratory conditions.
• Chronic Respiratory Problems: Prolonged exposure to mould, especially in large amounts, can cause chronic cough, sinus issues, and difficulty breathing.

2. Skin Irritation

• Mould exposure can cause skin rashes or itching, especially in sensitive individuals. Direct contact with mould spores may lead to dermatitis (skin inflammation).

3. Headaches and Fatigue

• Many people report experiencing headaches, dizziness, or fatigue due to mould exposure. This can be especially true for people who spend extended periods in mouldy environments.

4. Sinus and Nasal Problems

• Prolonged exposure to mould can lead to sinus infections, nasal congestion, and sinus headaches.

5. Weakened Immune System

• People with weakened immune systems (such as those undergoing chemotherapy or with HIV/AIDS) are more susceptible to mould infections, which can lead to more severe health problems like fungal infections.

6. Toxic Mould

• Some types of mould, such as Stachybotrys chartarum (black mould), produce mycotoxins that can have more serious health effects. These toxins can cause severe respiratory issues, neurological symptoms, and even damage to internal organs in extreme cases.

7. Mental Health Effects

• There have been reports suggesting that prolonged exposure to mould may lead to mental health issues like memory problems, confusion, or difficulty concentrating, though more research is needed in this area.

8. Infections

• In rare cases, mould can cause infections, especially in individuals with compromised immune systems. This can lead to conditions like fungal pneumonia.

Prevention and Treatment

• Prevention: The key to avoiding mould-related health problems is preventing moisture buildup. Keep indoor humidity levels below 60%, use dehumidifiers in damp areas, and fix leaks promptly.
• Treatment: If mould exposure has caused health issues, it is important to remove yourself from the contaminated environment. For those with allergic reactions, antihistamines or corticosteroids may help, while a doctor can prescribe stronger treatments for more severe reactions.
