Dizziness has a variety of causes, such as dehydration, changing the position of your head or an inner ear infection. In some cases, pollutants inside your home may cause dizziness and other symptoms. Identifying the cause of your dizziness can help you take steps to make the air in your home cleaner and purer.

Carbon Monoxide

Carbon monoxide (CO) is a colourless, odourless gas that can make you dizzy at low levels. Low levels of CO also cause headaches, disorientation, nausea and fatigue. At high levels, CO exposure can kill you. Fuel-burning appliances that aren't properly vented can create dangerous levels of CO in your home. If you suspect CO poisoning, get fresh air immediately and go to an emergency room. Doctors can diagnose CO poisoning through blood tests.


Formaldehyde is a chemical used in adhesive agents in carpets, plywood panelling, particle board, upholstery and other materials. New products may emit formaldehyde into the air, which can cause dizziness, headaches, skin rashes and eye, throat or nose irritation. For best results, avoid purchasing products that include formaldehyde. Air out new products before you bring them inside your home.

Sewer Gas

Sewer gas refers to a mixture of gases formed when household waste decomposes. Sewer gas often contains carbon dioxide, methane, sulphur dioxide and other gases. Exposure to sewer gas, which can enter your home through foundation cracks or floor drains, may cause dizziness, headache and nausea. Sewer gas sometimes smells like rotten eggs, depending on the mixture of gases. Flushing drains with water may help prevent sewer gas; if not, call a plumber.

Cleaning Chemicals

Household cleaning agents may also include chemicals that cause dizziness, according to the American Lung Association. Protect yourself by cleaning with nontoxic products, such as vinegar, whenever possible. In addition, read label instructions carefully and always provide adequate ventilation when cleaning.


Dizziness is sometimes associated with serious medical emergencies. Seek immediate medical attention if your dizziness is accompanied by a head injury, convulsions, ongoing vomiting, chest pain, fainting, headache, fever over 38.3 degrees C, very stiff neck, changes in vision or the inability to move an arm or a leg.
