Understanding Essential Oils and Sleep

Essential oils have emerged as a promising solution to sleep issues, offering a holistic approach to calming the mind and body. In this blog, we delve into the science behind essential oils, with a particular focus on Dolphin Clinic Tranquil Sleep blend and its key ingredients: bergamot, lavender, neroli, and clary sage.

Understanding Essential Oils and Sleep

Essential oils are concentrated plant extracts that capture the aromatic compounds of various botanicals. These oils have been used for centuries in traditional medicine practices for their therapeutic properties, including their ability to promote relaxation, alleviate stress, and improve sleep quality.

The olfactory system, responsible for our sense of smell, plays a significant role in how essential oils affect our bodies. When we inhale the aroma of essential oils, it triggers the limbic system in our brain, which is involved in emotions, memory, and arousal. This stimulation can evoke feelings of calmness, reducing stress and anxiety, ultimately paving the way for a more restful sleep.

Dolphin Clinic Tranquil Sleep Blend: A Closer Look

Dolphin Clinic Tranquil Sleep blend is specially formulated to promote relaxation and support a peaceful night's sleep. The synergistic benefits from these oils is much greater than the benefits of just one oil. This blend has been around for over 30 years!!

Let's explore its key ingredients and their potential benefits:

  1. Bergamot: Bergamot essential oil is derived from the peel of the bergamot orange fruit. It is renowned for its citrusy aroma with subtle floral undertones. Research suggests that bergamot oil may have sedative properties, helping to reduce anxiety and promote relaxation, thus facilitating sleep. Studies have also shown bergamot oil to have mood-lifting effects, which can further contribute to a sense of well-being conducive to sleep.
  2. Lavender: Lavender essential oil is perhaps one of the most well-known oils for promoting relaxation and improving sleep quality. Its soothing aroma has been extensively studied and is shown to have calming effects on the nervous system. Lavender oil may help lower heart rate and blood pressure, creating an optimal environment for restful sleep. Additionally, research indicates that lavender oil may enhance sleep quality by increasing slow-wave sleep, the deep sleep phase crucial for physical and mental rejuvenation.
  3. Neroli: Neroli essential oil is extracted from the blossoms of the bitter orange tree. Its delicate floral scent is prized for its calming and mood-boosting properties. Neroli oil is believed to have anxiolytic effects, reducing feelings of anxiety and stress. By alleviating emotional tension, neroli oil can help promote relaxation and improve sleep onset and duration.
  4. Clary Sage: Clary sage essential oil is derived from the flowering tops of the clary sage plant. With its earthy, herbaceous aroma, clary sage oil is often used to induce relaxation and relieve stress. Studies have shown that clary sage oil may have antidepressant effects, which can be beneficial for individuals experiencing sleep disturbances due to mood disorders. Additionally, clary sage oil may help regulate cortisol levels, the hormone associated with stress, thereby promoting better sleep quality.

Scientific Evidence and Studies

Numerous scientific studies support the efficacy of essential oils, including those found in Dolphin Clinic Tranquil Sleep blend, for improving sleep quality and reducing insomnia symptoms. For example:

  • A study published in the journal Evidence-Based Complementary and Alternative Medicine found that inhalation of bergamot essential oil reduced heart rate and blood pressure, indicating its potential as a natural sedative.
  • Research published in the International Journal of Nursing Practice demonstrated that lavender aromatherapy improved sleep quality and reduced anxiety in patients undergoing coronary artery bypass surgery.
  • A randomized controlled trial published in Complementary Therapies in Clinical Practice found that neroli oil inhalation reduced cortisol levels and subjective stress in postmenopausal women, suggesting its stress-relieving properties.
  • A study published in Phytotherapy Research reported that inhalation of clary sage essential oil reduced cortisol levels and improved mood in women experiencing menopausal symptoms.


Incorporating essential oils into your bedtime routine can be a simple yet effective way to promote relaxation and improve sleep quality.
