Research published by the Annals American Thoracic Society states that the ill effects of air pollution may cause many people to lose sleep.
Researchers have found that people living in regions with high air pollution are likely to face sleep problems compared to those living in areas with less air pollution.
Low quality and lack of sleep have adverse effects on humans. It increases the chances of accidents and also makes them moody. If this becomes a habit, then it can be harmful to your health. People not having adequate sleep are more likely to suffer from cancer and cardiovascular diseases.
How Air Pollution Affects your Airways
Poor air quality could affect your upper airways and increase sleep apnea chances. Dr. Ryan Donald, sleep medicine expert at The Ohio State University, said that they need to research more to conclude if poor air quality and sleep are interconnected.
There are many reasons for sleep apnea. Air pollution causes congestion in the upper airway, but mold, dust, and pollen can also cause allergies and increase the chances of sleep apnea.
A study has found an association between air pollution and sleep but not a cause-effect relationship. Dr. Martha E. Billings, professor of Medicine at the University of Washington, stated that there is no direct relationship between air pollution and sleep. Still, yes, pollution causes people not to have a sound sleep. It makes them toss and turn while they are asleep.
Billings said that more studies are required to understand the direct link between air quality and sleep.
Air Pollution and Mood
Adverse air pollution also affects your mood. A research published a few months back on people’s happiness pointed out that people living in more polluted areas are less happy.
Researcher Siqi Zheng of MIT China Future City Lab stated that pollution also has an emotional effect. Pollution makes people unhappy and causes them to make irrational decisions. Researchers also noticed that people who do not like to live in air-polluted areas move to clean cities and are likely to experience mood swings when they live in more polluted areas.
Also, people living in cities with adverse air pollution are aware of and worried about their adverse health effects.
Air Pollution and Health Problems
Air pollution has a direct link to increased chances of respiratory problems like asthma and lung cancer. Studies have shown a relationship between air pollution and many health problems.
A study published in 2017 by the researchers of the University of Birmingham, United Kingdom, stated that every additional 10 micrograms of PM 2.5/cubic meter of air increased the chances of cancer by 22% in seniors.
Another research stated that there are increased chances of premature birth if the pregnant woman is breathing highly polluted air. Other research stated that air pollution particles in the human brain could lead to dementia.
Indoor Air Quality and Sleep
Indoor air pollution could be more harmful than outdoor air. The outdoor air is around 4 to 5 times less polluted than indoors.
People are becoming more careful about what they eat and drink, but airborne chemicals can easily enter their bodies. One of the best ways to improve indoor air quality is to have more organic options at home.
One of the common airborne chemicals in our houses are toxic gases like Volatile Organic Compounds and PBDEs. It is next to impossible to find a house to stay in the United States without any airborne chemicals.
VOCs are found in homes in paints, hobby supplies, dry-cleaned clothes, aerosol spray, air fresheners, etc.
Your bedroom is the place where you can avoid toxic chemicals. Converting your bedroom into a healthy retreat can be a positive impact on your health and your children. Clean air helps you have a good night’s sleep and is significant for overall health.
Quality Air Purifier
Investing in a quality air purifier is the best way to improve air quality. Although it is almost impossible to limit toxins and pollution, an air purifier can help you breathe cleaner air.
You should look for an air purifier that has been tried and tested by users. Go for the one that removes more than 99% of airborne contaminants larger than 0.3 microns.
Also, choose the purifier that eliminates more than 2500 toxic gases and odors surrounding you, like ammonia, benzene, cooking odor, dry cleaning odor, etc.
I recently reviewed the Molekule Air Purifier It will eliminate VOCs and goes beyond what a standard HEPA filter can do. I highly recommend it.
Frequently Asked Questions
Can Air Quality Affect Sleep?
Air pollution could affect the quality of sleep. The researchers have focused on two aspects: sleep quality and sleep efficiency. Sleep quality is measured as the total number of hours you sleep and the times you wake up after falling asleep.
Can Air Pollution Make You Feel Tired?
The pollutants in the air cause an increase in fatigue. If you feel tired often, you should take some time off from working in poor air quality areas. One of the common symptoms of poor air quality is headache.
How Does Poor Air Quality Affect Health?
Long term exposure to poor air quality can lead to many health issues like:
- Development of chronic respiratory diseases
- Asthma
- A decrease in lung function

Sleep quality improves with air quality through several interconnected mechanisms:
Reduced respiratory issues: Poor air quality exposes you to pollutants, allergens, and irritants that can trigger congestion, coughing, and difficulty breathing. These disruptions during sleep can significantly impact its quality and leave you feeling tired and unrested. Cleaner air means less irritation and easier breathing, facilitating deeper, more restful sleep.
Improved oxygen intake: When air quality is poor, there may be less oxygen available in the environment. This can lead to hypoxemia, a condition where the blood oxygen levels are too low. This further disrupts sleep cycles as your body struggles to maintain proper oxygenation, leading to frequent awakenings and lighter sleep. Breathing clean air ensures optimal oxygen intake throughout the night, promoting deeper and more restorative sleep.
Enhanced nervous system function: Poor air quality can trigger inflammatory responses in the body, impacting the nervous system and disrupting its natural sleep-wake cycle. Pollutants and allergens can also directly affect neurotransmitters involved in sleep regulation, making it harder to fall asleep and stay asleep. Cleaner air minimizes these disruptions, allowing the nervous system to function optimally and promote healthy sleep patterns.
Reduced stress and anxiety: Poor air quality can contribute to a sense of unease and discomfort, even subconsciously. This can trigger stress and anxiety, making it harder to relax and fall asleep. Addressing air quality concerns can create a more calming and restorative sleeping environment, reducing stress and promoting relaxation, both crucial for good sleep.
Overall healthier environment: Good air quality goes hand-in-hand with other aspects of a healthy sleep environment. Cleaner air often means reduced dust mites, mold, and other allergens, leading to fewer allergy-related sleep disruptions. Also, maintaining good air quality often involves proper ventilation and temperature control, contributing to a comfortable and sleep-conducive environment.
It’s important to remember that individual sensitivity to air quality can vary, and addressing other sleep hygiene factors alongside improving air quality is crucial for optimal sleep. However, focusing on clean air significantly creates a foundation for good sleep by minimizing disruptions and fostering a calm, healthy environment for your body and mind to rest and recharge.
