Your home and your health are intricately connected. Considering that the average person spends 90% of their time indoors and takes 20,000 breaths each day, it makes sense!

Living in a mold and water-damaged indoor environment can cause a wide variety of symptoms that are often mistaken for other conditions. Those sickened or impacted by mold may spend years struggling with these chronic symptoms and the wrong diagnosis, if they get a diagnosis at all.

Some common symptoms of exposure include:
  • Brain fog and memory issues
  • Cognitive decline
  • Difficulty sleeping
  • Headaches
  • Digestives issues
  • Fatigue
  • Depression, anxiety, and mood swings
  • Skin problems
  • Respiratory issues
  • Chronic sinusitis
  • Muscle weakness or joint pain
  • Dizziness

A 2018 Tufts University study concluded that exposure to mold and mycotoxins was associated with asthma, wheezing, bronchitis, fatigue, musculoskeletal pain, headaches, anxiety, mood, cognitive issues, and depression.

A study from Brown University in 2007 showed that residents living in visibly damp and moldy households had a 44% HIGHER risk of depression than those in mold-free dwellings.

To complicate the situation even more, mold symptoms vary from person to person, even among individuals living in the same house.

This can occur for a variety of reasons, some of which include:

  • Underlying/pre-existing health conditions
  • Amount, type, and length of exposure
  • Age of people in the home
  • Genetics
  • Previous exposures

If you are experiencing any of the symptoms above, schedule an appointment with a knowledgeable health care practitioner and have your home evaluated for signs of mold and water damage.
