Kien Vuu, MD, assistant professor of health sciences at UCLA and author of Thrive State: Your Blueprint for Optimal Health, Longevity, and Peak Performance, told POPSUGAR that bergamot is also helpful for sleep thanks to its citrusy aroma, which promotes feelings of joy. "Positive vibes right before bed bedtime will promote good sleep," Dr. Vuu said. "It has a sunshiny scent, which helps relieve tension."
Studies published in Phytotherapy Research found that bergamot essential oil is beneficial to mental health, reduces stress, and improves sleep. Dr. Vuu recommends putting a few drops of bergamot onto a tissue or handkerchief and tucking it into your pillow.
