Problems of the immune system

There is nothing as bad as having a weak immune system that cannot defend your body from infections. This is what toxic mold can do to your immune system.

Problems to the reproductive system

Constant exposure to household mold may deny you the pride of having s healthy and well-functioning circulatory system. The mycotoxins produced by toxic black molds tend to be teratogenic.

Besides causing problems with fetal development, toxic mold can also cause miscarriages, infertility, and impotence.

Mental symptoms

Mental and neurological problems mostly occur with toxic black mold in homes. This is due to the fact that they are neurotoxic. They disrupt a person’s mental ability by killing the neurons in the brain. The neurons are cells that carry information within the brain and between the brain and other parts of the body. When the neurons are not working correctly, a person loses the ability to coordinate major functions of the body. This in turn causes nervous disorders such as

  • Depression
  • Hallucinations
  • Memory loss
  • Anxiety
  • Seizure
  • Dizziness
  • Aggression and irritability
  • Confusion
  • Short attention span


When the black mold invades your body, your immune system responds in a bid to protect you. Your immune system does this by releasing a sedative known as chloral hydrate. Chloral hydrate is meant to reduce the action of toxic black mold but it also causes fatigue. In addition, this mold also causes swelling and soreness of the joints and muscles. Other symptoms that accompany fatigue include drowsiness, joint pain, fever, general discomfort, recurring cold and weakness.


The mention of cancer is enough to convince anyone that mold is more toxic than any other heavy metals and pesticides. Once your immune system is impaired any kind of ailment can affect you and cancer is one of them.

In Conclusion  

It is obvious that any exposure to toxic mold can cause severe illness and even death. Unfortunately getting to know that you are harboring mold in your home can be an uphill task. When mold is growing in places that are not much visible, a bad odor may be the only clue that they are around. If you get any such smell, check your house thoroughly to locate the mold before they get worse.

As usual, prevention is better than cure. Experts advise that the only way to deal with mold infestation is to eliminate moisture in your household. Getting a good quality air purifier is another way to ensure that your home is not invaded by mold.
