Having a healthy and comfortable bedroom is important for getting a good night’s sleep. However, there are many factors in bedrooms that can negatively impact health and sleep quality. In this article, we will explore common bedroom issues like dust mites, mold, furniture materials, and more to understand if your bedroom environment could be making you sick.
Dust Mites
One of the most common bedroom allergy and asthma triggers is dust mites. Dust mites are microscopic insects that live in bedding, carpets, furniture, and other fabric materials. They feed on dead skin cells that humans naturally shed every day. It is estimated that millions of dust mites can live in your bed and bedroom.
Dust mites themselves are too small to see with the naked eye. However, the waste material and carcasses they produce can build up over time and cause allergic reactions. Signs of a dust mite allergy include sneezing, runny nose, watery eyes, and other cold-like symptoms that may get worse at night or when you are in your bedroom.
To reduce dust mites, it is recommended to:
- Wash bedding weekly in hot water (at least 130°F) to kill mites.
- Use allergen covers for pillows, mattresses, and box springs.
- Limit stuffed animals and upholstered furniture which collect dust and mites.
- Use hardwood, tile, or vinyl flooring instead of carpet.
- Clean and vacuum regularly.
Mold
Mold is another common bedroom allergen and irritant. Mold grows in damp, humid environments. Excess moisture in the bedroom from issues like leaks, flooding, steam from bathrooms, or condensation provides optimal conditions for mold.
Inhaling mold spores can cause allergic reactions, asthma flare-ups, and other respiratory problems for sensitive individuals. Symptoms include coughing, wheezing, difficulty breathing, and nasal congestion. Mold exposure has also been linked to skin irritation.
To prevent mold growth in the bedroom:
- Fix any water leaks or moisture sources.
- Use exhaust fans in bathrooms and when showering.
- Allow adequate ventilation.
- Use a dehumidifier to regulate humidity.
- Clean any existing mold properly with bleach or vinegar.
Off-Gassing from Furniture
Many types of new furniture found in bedrooms can release volatile organic compounds (VOCs) into the air through a process called off-gassing. VOCs are carbon-based chemicals that easily evaporate at room temperature. Sources of VOCs include:
- New mattresses made with polyurethane foam and adhesives
- Wooden furniture finished with chemicals like varnish, stains, and formaldehyde
- Pressed-wood products like plywood and particleboard
- Glues and adhesives in furniture
- Carpets and flooring
VOCs can irritate the eyes, nose and throat in the short-term. Headaches, nausea, and dizziness are also common symptoms. Long-term exposure to VOCs may increase cancer risks and damage the liver, kidneys and central nervous system according to some studies.
Tips to reduce VOC exposure from bedroom furniture:
- Air out new furniture outside or in a well-ventilated room for 1-3 days before putting in the bedroom.
- Open windows regularly to circulate fresh air.
- Use an air purifier with activated carbon filtration.
- Choose solid wood or metal furniture over pressed-wood products when possible.
- Use low-VOC paints, stains, and finishes.
- Avoid new carpeting and use natural fiber area rugs instead.
Particulates and Allergens in Bedding
Dust, pet dander, pollen, and other microscopic allergens and irritants can collect in bed sheets, pillows, comforters, and other bedding materials. When you sleep in the bed, these particles get stirred up and can be breathed in or come into contact with skin and eyes.
Symptoms from exposure to particulates in bedding include:
- Sneezing
- Itchy, watery eyes
- Runny nose
- Wheezing and coughing
- Skin irritation and rashes
- Asthma attacks
Ways to reduce particulates in bedding:
- Encase pillows and mattresses in allergen-proof covers.
- Wash sheets weekly in hot water.
- Use hypoallergenic blankets and comforters.
- Choose natural fiber bedding instead of synthetic.
- Dry clean comforters 2-3 times per year.
- Avoid sleeping with pets in bed.
Indoor Air Pollutants
Many additional air pollutants can accumulate in poorly ventilated bedrooms and cause health issues. These include:
- Carbon monoxide – Invisible, odorless gas produced by gas stoves, furnaces, hot water heaters and other fuel-burning appliances that can be deadly at high concentrations.
- Radon – Radioactive gas that enters homes from soil and bedrock underneath.
- Smoke – From tobacco, candles, incense, wood stoves.
- Air fresheners and cleaning products – Contain VOCs and formaldehyde.
- Ozone – Can be emitted from printers, copiers, and air purifiers.
Exposure to indoor air pollutants are linked to increased risks of headaches, fatigue, respiratory irritation, asthma, heart disease, cancers, and neurological effects.
Improving bedroom air quality:
- Ensure proper ventilation and bring in fresh air by opening windows regularly.
- Do not smoke indoors.
- Install carbon monoxide and radon detectors.
- Limit use of candles, incense, fragrances, chemical cleaners.
- Only use air purifiers and filters that do not emit ozone.
Poor Ventilation and Lack of Air Circulation
Stagnant air can allow allergens, chemical fumes, humidity, and other pollutants to build up in a bedroom. Most experts recommend exchanging the air at least 2-3 times per hour in bedrooms through ventilation, fans, or open windows.
Signs of poor bedroom ventilation include:
- Stuffy, stale air
- Strange or musty odors
- Condensation on windows and walls
- Visible dust, allergens, and particles floating in the air
Health consequences of poor bedroom ventilation:
- Allergy and asthma symptoms
- Increased risk for airborne infections
- Headaches, dizziness, nausea from inhaling chemicals
- Excess moisture leading to mold growth
Tips for improving bedroom ventilation:
- Open windows regularly to circulate fresh outdoor air.
- Use ceiling or window exhaust fans.
- Adjust HVAC systems to bring in adequate fresh air.
- Don’t block air vents or undercut doors.
- Use floor and table fans to keep air moving.
Temperature and Humidity
The optimal temperature for sleeping is around 65°F. Temperatures above 75°F or below 54°F can disrupt sleep quality and health. Extremely hot or cold bedrooms can also aggravate certain medical conditions.
In addition, the ideal humidity level in bedrooms is 30-50%. Humidity outside this range can allow mold and mildew growth and the proliferation of dust mites and bacteria.
Signs that temperature or humidity is unsuitable in your bedroom:
- Frequent night sweats or feeling too hot or cold when trying to sleep
- Dry eyes, skin, throat, nasal passages
- Cracks in furniture or warped floors from excess moisture
- Mold or mildew odors
- Condensation building up on windows
Ways to regulate temperature and humidity in the bedroom:
- Use air conditioning and heating systems.
- Use a humidifier or dehumidifier.
- Ensure adequate insulation.
- Seal any air leaks.
- Use fans for air circulation.
- Open windows when outdoor conditions permit.
Excessive Noise, Light, and Other Disturbances
Chronic noise pollution and excess light in the bedroom during sleep can harm health in several ways:
- Interrupts and fragments sleep cycles
- Increases stress hormone levels
- Raises blood pressure and heart rate
- Impairs cognitive function and memory
Sleep disturbances from noise and light have been linked to problems like insomnia, daytime fatigue, irritability, depression, heart disease, and obesity.
Common bedroom noise and light issues:
- Streetlights shining into windows
- Noisy roads, neighbors, construction
- Televisions, radios, phones
- Pets moving around
- Doors opening and closing
- Mattress creaking

Ways to reduce disturbances in the bedroom:
- Use blackout curtains or an eye mask.
- Wear earplugs.
- Use white noise from a fan or machine.
- Ensure the mattress is in good condition.
- Keep pets outside of the bedroom.
- Ask noisy household members to be quieter at night.
- Turn off and remove electronic devices.
Non-Breathable Bedding and Sleepwear
Certain types of bedding, mattresses, pajamas, and nightgowns can be overly insulating and trap heat. This can cause you to overheat while sleeping. Excessive sweating at night can lead to dehydration, skin irritation, and disruption of normal sleep cycles.
Examples of non-breathable bedding and sleepwear materials include:
- Thick flannel sheets
- Waterproof mattress pads
- Duvets and comforters that are too warm for the temperature
- Memory foam, latex, and polyurethane foam mattresses
- Flannel pajamas
- Non-breathable synthetic fabrics like polyester
Tips for improving air circulation in bed:
- Choose breathable cotton, wool, bamboo, or Tencel sheets and pajamas.
- Use lighter blankets if too warm.
- Choose a medium-firm innerspring or hybrid mattress.
- Avoid memory foam mattresses if you sleep hot.
- Keep the thermostat cool enough at night.
- Remove unneeded mattress pads and toppers if too warm.
