Lavender (Lavandula angustifolia) has a long tradition of use as a calming herb for sleep and relaxation, but recent scientific studies provide moderate support for its use in managing insomnia. Aromatherapy with lavender oil has been the subject of several clinical trials, some of which have found that lavender scent can improve sleep quality, increase total sleep time, and reduce symptoms of mild insomnia. For example, a 2015 systematic review published in the journal Evidence-Based Complementary and Alternative Medicine concluded that inhalation of lavender essential oil appears to have a positive effect on sleep quality, particularly in individuals with mild sleep disturbances. Another randomized controlled trial found that exposure to lavender fragrance improved sleep onset, quality, and duration in college students and women with insomnia symptoms. The mechanism is thought to involve lavender’s interaction with neurotransmitters such as GABA, which plays a role in reducing nervous system activity and promoting relaxation. However, most studies have small sample sizes, short durations, and sometimes lack rigorous blinding or control groups. Although adverse effects are rare and lavender is generally considered safe, more extensive research is needed to confirm long-term efficacy and optimal administration methods (e.g., aromatherapy, oral supplements). In summary, while the traditional use of lavender for sleep is well-established and there is moderate scientific evidence supporting its benefits for insomnia, further high-quality studies are warranted to solidify its role in clinical practice.
