6 Aromatherapy Essential Oils for Stress Relief and Sleep
Scents are
powerful — a simple smell can immediately trigger a powerful memory,
place, or person. Scents have power to evoke emotions and memories
instantly and can directly impact our bodies through our nervous system.
The olfactory nerve gives us our sense of smell and starts from our nose and enters the skull through tiny holes to connect directly to the brain. This nerve rapidly sends signals to many different parts of the brain, including the limbic system and amygdala,
which are in charge of emotions, mood, and memory. These systems are
also in charge of regulating our autonomic nervous system, which can
either trigger a fight-or-flight response, quickening our breath, heart
rate and raising our blood pressure, or can soothe us through turning on
the parasympathetic nervous system, which relaxing our bodies. This
theory helps explain why scents can so quickly trigger physical
reactions in our bodies and have lasting effects after the scent is
gone. Essential oils like lavender have even been shown to react the same way biochemically that anti-anxiety medications do with certain neuroreceptors.
Aromatherapy is
a complementary and alternative medicine practice that taps into the
healing power of scents from essential oils extracted from plants in
order to balance your mind, body, and spirit. Essential oils can be
diluted by water and diffused into the air or a few drops can be gently
rubbed into acupressure points on the body. Studies have shown that
specific essential oils used in aromatherapy can help relieve stress,
relax the body, and promote better sleep.
Here are six essential oils that can help relieve stress and promote sleep.
1. Lavender
Lavender essential oil is one of the most well-studied essential oils in terms of its relaxing effects. One study
found that lavender oil aromatherapy calmed the nervous system —
lowering blood pressure, heart rate, and skin temperature as well as
changing brain waves to a more relaxed state.
Lavender can also help with mild insomnia and provide better quality of sleep. Lavender aromatherapy has also been found to help reduce anxiety and depression in women with postpartum depression. Lavender has also been found to help reduce anxiety in many medical settings, such as dental offices, the intensive care unit, and during preparations before surgery.

The scent of lavender stimulates brain pathways, including our limbic system, which is connected to our emotional response and memories. Studies using electroencephalography (EEG), which measures brain waves, and brain imaging using functional magnetic resonance imaging (fMRI) show significant changes during lavender aromatherapy consistent with its relaxing effects.
Lavender
aromatherapy is generally safe, except for those with allergies to
lavender. If you are applying it regularly on your skin, it’s important
to talk to your doctor since lavender can have estrogenic effects, so
regular use should be taken with caution, especially in children.
2. Lemon or Yuzu
A new study from Japanese researchers has found that yuzu
citrus scent can soothe stress and anxiety and lower your heart rate in
just 10 minutes, with effects lasting for almost half an hour. Yuzu is a type of East Asian yellow citrus fruit often used in Asian cuisine.
The Japanese
custom of yuzu-yu or yuzu baths in which whole yuzus float in hot baths
to relieve stress dates as far back as the 18th century. You can try
diffusing yuzu or other similar citrus fruit essential oil, which can be
more affordable, including lemon. Some earlier studies have found that
lemon can also be stimulating and increase heart rate, so the results are mixed, but you can try it out to see how it affects you.
3. Bergamot
Citrus bergamot
is a hybrid fruit somewhere between a bitter orange and lemon or lime
and is used to create bergamot essential oil. It has been traditionally
used in Italian folk medicine but has many new studies
to support its ability to relieve tension and anxiety. Bergamot
essential oil is often used in fragrances as well as food flavoring, and
has also been thought to have antibacterial properties.
Five out of six clinical studies, conducted between 2009 to 2013, have found that bergamot essential oil aromatherapy reduces heart rate, blood pressure, and stress.
Recent studies have found that bergamot can also reduce chronic pain and even change brain wave patterns on EEG.
4. Ylang Ylang
Ylang Ylang
essential oil is sweet floral aromatic extracted from the flower of a
tropical tree in Southeast Asia. Ylang Ylang aroma has been shown to be
relaxing and decrease blood pressure in many small studies. One study found that Ylang Ylang aroma calmed the nervous system, leading to lower heart rate and blood pressure.
5. Clary sage
Clary sage oil
is extracted from the clary sage herb, a close relative of the common
garden herb sage. Clary sage essential oil has been found to help people relax during dental procedures. Clary sage oil aromatherapy has also been shown to have antidepressant-like effects.
6. Jasmine
Jasmine has a sweet aroma and can be relaxing fragrance. Jasmine essential oil is less well-studied, but does have one study that suggests that the odor of jasmine tea can be calming.
There are many
more therapeutic essential oils to explore, including earthy vetiver,
Valerian root, or Roman chamomile. While most essential oil
aromatherapies have not yet been rigorously scientifically studied, many
more may have calming effects.
Qualities of essential oils can vary widely based on brand and price
and are not regulated by the Food and Drug Administration or any other
government agency, so be sure to research the brand and check to make
sure the oil is of therapeutic quality and purity.
