For centuries, people around the world have used essential oils for their fragrance and potential wellness benefits. Today, many people use diffusers to disperse essential oils throughout their homes.
They are commonly used to promote relaxation, boost energy, ease nausea, or create a pleasant scent. But one question comes up often:
Are essential oils safe to inhale?
The answer depends on the type of oil, how it's used, and the person using it. While many people enjoy essential oils without issue, they are not regulated like medications, and product quality can vary.
If you're concerned about odors, allergies, or airborne contaminants in your home, a professional indoor air quality assessment can help identify the source rather than simply masking it with fragrances.
Before using essential oils regularly, it's important to understand both the potential benefits and the possible risks.
Essential oils are highly concentrated liquids extracted from plants. They contain the natural compounds that give plants their scent and aroma.
Manufacturers use methods such as steam distillation, cold pressing, or solvents to produce different types of oils.
Essential oils are commonly found in:
Despite their name, "essential" does not mean they are required for good health like essential vitamins or fatty acids.
Because these oils are highly concentrated, they should always be used according to the manufacturer's directions. Some oils can irritate the skin or respiratory system, especially in children or people with allergies or asthma.
Essential oils are not automatically dangerous, but they are not risk free.
According to the National Capital Poison Center, some essential oils can be harmful if swallowed, absorbed through the skin, or accidentally inhaled into the lungs. In some cases, aspiration can lead to serious lung irritation or pneumonia.
To reduce risk:
Essential oils are widely used in aromatherapy to promote relaxation and emotional well-being. Some studies have explored their antimicrobial or insect-repelling properties, but there is limited evidence that they can treat or cure medical conditions.
Essential oils are not appropriate for everyone.
Pregnant women, young children, people with asthma or COPD, and pet owners should use extra caution. Some essential oils may contain impurities or additives, and certain oils can be harmful to both people and animals.
The International Organization for Standardization (ISO) published guidance on essential oils in ISO 4720 (2018) for those interested in learning more about product standards.
The American Lung Association (ALA) also recommends taking precautions before using essential oils. Their guidance includes:
If you have asthma, inhaling essential oils may trigger coughing, wheezing, or shortness of breath. People living with COPD should also consult a healthcare professional before using essential oils.
The American Lung Association notes that "Inhaling essential oils directly, or in high concentrations, can trigger symptoms in damaged lung tissues."
If you notice respiratory symptoms indoors, the cause may not always be essential oils. Poor indoor air quality, excess humidity, or hidden mold growth can produce similar symptoms. A professional indoor air quality assessment can help identify potential airborne contaminants.
Many people enjoy using essential oils, but they should be used thoughtfully and according to the manufacturer's instructions.
If you develop a rash, breathing difficulties, or other concerning symptoms, discontinue use and seek medical advice.
The American Lung Association summarizes its position with a simple recommendation:
"Adding anything, including essential oils, to the air you breathe is not recommended. Fresh, clean air is best."
Maintaining good ventilation, controlling indoor humidity, and addressing moisture problems can have a greater impact on indoor air quality than simply masking odors with fragrances.
