Essential oils have been used for centuries to promote better sleep. They can be absorbed by the skin or inhaled, in which case the scent molecules travel from the olfactory nerves directly to the brain and impact the amygdala, the emotional centre of the brain. While research on the use of essential oils is limited, lavender oil is widely recognized as a natural sleep aid. Other essential oils that can help improve sleep include cedarwood, bergamot, and chamomile.

What You'll Learn
Inhalation methods
Aromatherapy is a centuries-old holistic healing technique that uses essential oils extracted from aromatic plants to promote physical and emotional well-being. Essential oils can be inhaled, diffused, or applied to the skin.
When essential oils are inhaled, the scent molecules are picked up by receptors in the nose and sinuses and travel to the olfactory bulb, the olfactory cortex, and finally to the limbic system, the part of the brain that controls emotions, memory, and arousal, among other functions.
Aroma sticks or essential oil inhalers are portable plastic sticks with an absorbent wick that soaks up essential oil. They come with a cover to keep the scent contained until you're ready to use it.
Diffusers are ideal for helping you sleep because they are long-lasting and create mist continually throughout the night. There are different types of diffusers that use different methods of releasing fragrance into the air. The type you choose may depend on how strong you want the scent to be and how easy the diffuser is to clean. Common diffusers use ultrasonic technology, which breaks down essential oils and water using vibrations rather than heat, misting them into the room. Other types of diffusers include:
- Passive diffusers: These release fragrance through materials such as ceramic, natural wood, or reeds.
- Heat diffusers: These use fire or electricity to warm up the oil until it evaporates into the air.
Essential oils can also be inhaled by putting a few drops on a pillow or cotton balls kept in the room while you sleep.

Topical application
There are several ways to apply essential oils topically for better sleep. One way is to massage the diluted oil onto the neck, shoulders, feet, and palms before bedtime. This can help relax the body and improve sleep quality. Another method is to apply the diluted oil to the pulse points, such as the wrists, temples, and behind the ears. This allows the oil to be quickly absorbed into the bloodstream, providing potential therapeutic benefits.
Additionally, essential oils can be added to bathwater or bath salts for a soothing and aromatic experience. This can help relax the body and mind, preparing for a good night's sleep. It is recommended to use 5-10 drops of essential oil in the bathwater or bath salts.
When choosing an essential oil for sleep, lavender is often recommended due to its calming and stress-relieving properties. Research has shown that lavender may help reduce the time it takes to fall asleep, improve sleep duration, and increase restorative slow-wave sleep. Other essential oils that can aid in sleep include chamomile, which promotes relaxation and alleviates headaches; bergamot, which helps reduce heart rate and blood pressure; and cedarwood, which has sedative effects.
While essential oils can be beneficial for sleep, it is important to exercise caution, especially for children, pregnant women, and those who are breastfeeding. It is always advisable to consult a healthcare professional before using essential oils, especially if one has a history of reactions to topical products or skin sensitivities.

Aromatherapy
Research suggests that certain essential oils may help promote relaxation and sleep. However, essential oils may not work for everyone, and a person may have to try a variety of essential oils to discover one that works best for them. Many people consider lavender to be the most calming essential oil. A 2020 review of the safety and efficacy of lavender essential oil states that the oil has both calming and sedative properties that help promote both physical and psychological relaxation. The oil contains the bioactive components linalool and linalyl acetate, which interact with neurotransmitters in the brain to alleviate anxiety and depression and induce relaxation.
Other essential oils that may help promote sleep include chamomile, peppermint, clary sage, and valerian root. Clary sage is believed to calm the mind and reduce anxiety by lowering cortisol levels, the body's primary stress hormone. Valerian root has been dubbed nature's alternative to valium and is known for its sedative properties, making it an effective treatment for insomnia.
It is important to note that essential oils are not regulated by the U.S. Food and Drug Administration, so it is crucial to seek out a trusted brand and use them in small doses or after consulting a medical professional.

Effectiveness
The effectiveness of sleep essential oils is a topic of ongoing research. While some studies have demonstrated the positive effects of essential oils on sleep, others remain inconclusive. Aromatherapy, the practice of inhaling essential oil scents or vapors, has been used as a medical treatment since ancient times to obtain positive health effects. Research suggests that certain essential oils may promote relaxation and sleep. However, it is important to note that essential oils may not work for everyone, and individuals may need to try different oils to find the ones that work best for them.
Lavender oil is widely recognized as a natural sleep aid and has been the focus of several studies. A 2005 study found that lavender oil increased the amount of slow- and deep-wave sleep in participants, who reported feeling more vigorous the next morning. Another study on cardiac patients with sleep disorders found that participants who inhaled lavender and peppermint oil experienced better sleep quality compared to those who inhaled scented distilled water. Additionally, hospital patients with coronary artery disease and postpartum mothers who inhaled lavender oil reported improved sleep and reduced anxiety.
Other essential oils that may promote sleep include chamomile, peppermint, clary sage, and valerian root. Clary sage is believed to reduce anxiety and act as a natural antidepressant by lowering cortisol levels. Valerian root, often referred to as nature's alternative to valium, has sedative properties that may help treat insomnia and aid in falling asleep faster.
While the effectiveness of sleep essential oils varies among individuals, they are generally considered safe to use. However, it is important to use them in small doses and dilute them before applying them to the skin to prevent allergic reactions and irritations.

Safety considerations
While essential oils can be a great natural sleep aid, there are some safety considerations to keep in mind. Firstly, it is important to consult your doctor before using essential oils, especially if you are taking any medications or have any health concerns. Essential oils should never be taken internally without the supervision of a health professional, and if you are pregnant or breastfeeding, it is important to speak with your healthcare provider before use.
Since essential oils are highly concentrated, they should always be diluted before use, especially if applying them to the skin. Pure essential oils can cause stinging and burning sensations if applied undiluted. It is recommended to mix essential oils with a carrier oil, such as in a bath or for topical application. Before using a new essential oil, it is advisable to perform a patch test to check for any skin irritation or allergic reactions. This can be done by applying a few drops of diluted oil to the skin on your inner arm, covering it with a bandage, and observing for any reactions over the next 48 hours.
It is also important to be cautious when inhaling essential oils. Avoid inhaling them directly from the bottle, and instead, use a diffuser or mix them with water to create a room spray. To avoid over-inhalation, take breaks or set your diffuser to turn off after an hour. Additionally, be wary of exaggerated marketing claims and always purchase essential oils from reputable sources to ensure their quality.
While research suggests that essential oils can be safe and effective for improving sleep, it is important to remember that they may not work for everyone. It may take some trial and error to find the right essential oil and method of application that works best for you. Always listen to your body and discontinue use if you experience any unusual side effects.
