Essential oils and their calming aromas
Essential oils have been used for thousands of years to promote physical, emotional, and spiritual well-being. They are considered more powerful than the plants from which they are derived. The calming and relaxing aromas of essential oils can help you drift off and stay asleep all night, leaving you feeling refreshed and rested.
The sense of smell is directly connected to the brain's limbic system, which controls memories and emotions. As you inhale the aromas of essential oils, cells inside the nose send this information to the brain through the olfactory nerve, impacting our emotional reactions and memories. It is believed that inhaling essential oils or absorbing them through the skin may help activate the brain chemicals involved in controlling sleep.
There are various essential oils with calming properties that can be used to promote sleep. A popular choice is lavender, which is known for its relaxing effects and is often used as a natural sleep aid. Other essential oils that can help with sleep include chamomile, jasmine, frankincense, ylang-ylang, vetiver, geranium, amyris, and clary sage. These oils can be used individually or blended to create a calming atmosphere that enhances sleep.
It is important to note that essential oils should be used with caution. They can cause allergic reactions and other negative side effects, so it is recommended to consult a trained aromatherapist, nurse, doctor, or pharmacist before incorporating them into your sleep routine. Additionally, essential oils should always be diluted with a vegetable-based oil, such as olive or coconut oil, to prevent skin irritations and allergic reactions.

Diffuser types and their uses
Diffusers are a great way to improve your sleep quality and create a calming environment to aid in better sleep. They are also known to improve air quality and enhance your mood. There are several types of diffusers, each with its own unique mechanism for dispersing essential oils into the air. Here are some of the most common types:
Ultrasonic Diffusers
Ultrasonic diffusers are one of the most popular types of essential oil diffusers. They use ultrasonic vibrations to disperse essential oils into the air, creating a fine, cool mist. This type of diffuser requires water as a medium, and the ultrasonic vibrations cause the water and oil mixture to break apart into tiny particles, which are then released into the air. Ultrasonic diffusers are known for their quiet operation, energy efficiency, and gentle diffusion, making them ideal for use in bedrooms or relaxation spaces.
Evaporative Diffusers
Evaporative diffusers disperse oils into the air through the natural process of evaporation. They use a fan or rely on airflow to help the essential oils evaporate and spread their aroma. These diffusers typically contain an absorbent material, such as a filter, wick, or pad, onto which a few drops of essential oil are added. Evaporative diffusers are simple to use, often portable, and do not require water or heat, making them convenient for on-the-go use.
Heat Diffusers
Heat diffusers use heat to evaporate essential oils and disperse their aroma into the air. They typically have a simple setup, with a small amount of essential oil placed on a tray or pad above a heat source. The heat source can be electric, a candle, or even a light bulb. Heat diffusers are known for their simplicity, affordability, and silent operation. However, it's important to note that using heat can alter the chemical composition of essential oils, potentially reducing their therapeutic benefits.
Nebulizing Diffusers
Nebulizing diffusers, also known as atomizing diffusers, use a pump to break down essential oils into smaller molecules, which are then released into the air. They are said to supply greater therapeutic benefit than other types of diffusers because of the way they break down the oils. However, cleaning a nebulizing diffuser can be time-consuming, especially after using thicker essential oils.
Waterless Diffusers
Waterless diffusers, as the name suggests, disperse essential oils without the use of heat or water. Instead, they use an atomizer to create super-fine particles of pure essential oil, which are then distributed into the air. Waterless diffusers are ideal for medium to slightly larger rooms and often come with diffusion settings and optional colour-changing lights.
Tea Light Diffusers
Tea light diffusers, such as the Terra Cotta Tea Light Diffuser, use passive heat to slowly release essential oils. They are made of absorbent and porous materials like terra cotta, which soak up the essential oils. When placed in a warm location, the passive heat releases the oil into the air. Tea light diffusers are perfect for smaller spaces and create a subtle, elegant ambiance.

The science behind aromatherapy
Aromatherapy is a natural way to improve sleep quality. Essential oils have been used for thousands of years to promote physical, emotional and spiritual well-being. The practice involves diffusing oils in a bedroom at night to enhance sleep. Each essential oil has its own composition, scent, and benefits. For instance, blends of lavender, frankincense, ylang-ylang, Roman chamomile, and vetiver help reduce anxiety, depression, and sleep-related problems.
While research shows that essential oils are safely metabolized in the body, it is important to dilute them with vegetable-based oils such as olive or coconut oil to prevent skin irritations and allergic reactions. The Alliance of International Aromatherapists recommends diluting essential oils to a 2-3% concentration for massages and body lotions.
Additionally, facial steaming 15 to 20 minutes before bed can be an effective way to relax and promote deep sleep. A small 2019 study found that adult men who tried steam inhalation were more relaxed and experienced deeper sleep. This can be achieved by adding a few drops of essential oil to a pot of warm water and inhaling the steam.
Overall, while the specific mechanisms of aromatherapy's impact on sleep are not fully understood, the practice has been shown to be a safe and natural way to improve sleep quality and promote relaxation.

DIY aromatherapy
Aromatherapy is a natural way to support your physical and emotional well-being, and it's particularly effective for promoting relaxation and great sleep. Essential oils are the foundation of aromatherapy and can have a calming effect on the body and mind, making them an effective tool to promote sleep.
Diffusers
Diffusers are ideal for helping you sleep because they are long-lasting and create a mist continually throughout the night. There are different types of diffusers, and the one you choose may depend on how strong you want the scent to be and how easy the diffuser is to clean. Most common diffusers have ultrasonic technology, which uses vibrations to break down essential oils and water, which are then misted into the room. To use a diffuser, place a few drops of essential oil into the water and watch as the vapour drifts out of the small opening at the top of your diffuser.
Facial steaming
Facial steaming is an effective way to relax before sleep. Simply add one to three drops of essential oil to a large pot of warm water and lean over the pot with a towel covering your head for about 10 to 15 minutes.
Hot towel compress
You can also use the water from the facial steaming method to make a hot towel compress. Wrap the towel around a sore area to encourage muscle relaxation.
DIY linen spray
Customise your own scent by mixing essential oils with water, spritz it on your bedding, and lay your head on a light cloud of comfort.
Baths
Add a few drops of essential oil to your bath to create a relaxing environment and promote sleep.
Pillow spray
Shake a drop of a sleep-promoting essential oil onto a cotton pad and place it by your pillow in the evening for an hour.
Tea
If strong essential oils are not for you, you can try lighter forms of aromatherapy by drinking a hot cup of tea with a few drops of essential oil mixed in.
Candles
Like tea, candles are another way to enjoy lighter forms of aromatherapy.
When using essential oils, it is important to dilute them with a vegetable-based oil, such as olive or coconut oil, to prevent skin irritation and allergic reactions. The Alliance of International Aromatherapists recommends diluting essential oils to a 2-3% concentration for massages and body lotion.
