Mold Restoration

If you’ve been feeling unwell at home and experiencing fatigue, headaches, sneezing, or brain fog, but those symptoms ease when you’re away, your home itself could be the problem.

This phenomenon is often referred to as Sick House Syndrome, and it’s more common than you might think. Hidden hazards like moldradonasbestos, and poor air circulation can silently impact your health over time.

In this post, we’ll explain:

  • What “Sick House Syndrome” is
  • Common symptoms to look for
  • Potential environmental causes
  • What to do if you suspect your home is making you sick

What Is Sick House Syndrome?

Sick House Syndrome (also called Sick Building Syndrome when referring to workplaces) describes a condition in which people experience health symptoms that seem to be linked to time spent indoors, but no specific illness can be diagnosed. The symptoms often go away or improve when the person leaves the building.

While it may sound vague, the cause is often real and measurable: hidden environmental hazards in your home’s air, structure, or systems.

Signs Your Home Might Be Making You Sick

Here are some of the most common symptoms associated with Sick House Syndrome. These symptoms often seem mild or vague at first, but can escalate over time.

Cognitive & Neurological Symptoms:

  • Headaches
  • Brain fog
  • Dizziness
  • Fatigue

 Respiratory & Allergic Symptoms:

  • Sneezing or coughing
  • Chest tightness
  • Nasal congestion
  • Itchy or watery eyes

 Systemic or General Symptoms:

  • Nausea
  • Skin irritation or rashes
  • Sensitivity to smells

One of the strongest signs that your home is contributing to these symptoms? You feel noticeably better when you leave for work, errands, or vacation, but worse again when you return.

Common Hidden Causes of Sick House Syndrome

The causes of Sick House Syndrome are often invisible and require professional testing to detect. Here are the most common culprits:

1. Mold and Moisture

Mold (like black mold) thrives in damp, dark environments and releases spores and mycotoxins that can trigger asthma-like and allergic symptoms. It often hides behind wallsunder flooringinside HVAC systems, or in crawlspaces—places most homeowners never check.

2. Radon Gas

Radon is a naturally occurring radioactive gas that can seep into homes through foundation cracks or basements. It’s odorless, colorless, and the second-leading cause of lung cancer in the U.S. after smoking.

3. Asbestos and VOCs

Older homes may contain asbestos in insulation, flooring, or ceilings. In newer homes, volatile organic compounds (VOCs) from paint, carpet, furniture, and cleaners can build up in poorly ventilated spaces.

4. Poor Indoor Air Quality

Lack of proper ventilation or clogged HVAC systems can cause indoor air to stagnate, concentrating pollutants like dust, pet dander, cleaning chemicals, or carbon monoxide.

What About Sick Building Syndrome?

You may have also heard the term Sick Building Syndrome—a closely related condition to sick house syndrome that occurs in offices, schools, and other commercial buildings. Like Sick House Syndrome, it describes a range of symptoms (such as fatigue, headaches, and respiratory irritation) that seem linked to time spent in a particular indoor space.

The difference? Sick Building Syndrome typically refers to workplaces or shared buildings where issues like poor ventilation, chemical pollutants, and mold growth affect multiple occupants.

In both cases, the indoor environment is the root cause, and the symptoms usually improve when the person leaves the building.

So if you feel better when you’re not at work, your body might be telling you something important: it’s time to check your environment.

Whether you’re dealing with a home or workplace, PuroClean offers free inspections to help uncover the hidden cause.
