Although the "lemon by your bed" trend seems like simply another social media craze, there is some scientific basis for the possible advantages of lemon aromatherapy. The secret is the volatile chemical molecules lemons contain, especially limonene, which gives the fruit its distinct lemony smell. Cutting a lemon releases these components into the air, producing a naturally occurring kind of aromatherapy. By activating the olfactory system, which is closely linked to the limbic system in the brain, inhaling these molecules can Emotions, behaviour, and long-term memory all depend on the limbic system in great measure. Many aromatherapy techniques have their roots in this link between scent and emotion, which also helps some smells arouse strong memories or emotions. Studies on citrous smells—including lemon—have found that they may improve cognitive ability and mood. Rats' stress levels were lowered by lemon fragrance, according a 2008 study written up in the journal Psychoneuroendocrinology. The researchers noted that exposure to lemon scent lowered corticosterone levels, a hormone linked to stress, implying that lemon scent may have stress-releasing properties. Another 2005 study that was written up in Chemical Senses showed that lemon oil vapours improved people's mood. When the lemon aroma was present, participants said they felt less melancholy, more cheerful, and less nervous. According to this study, lemony scent could perhaps aid to lower anxiety and boost mood. Research has also suggested that citrous smells might have antibacterial qualities. Citrous essential oils—including lemon—showered antibacterial action against several microorganisms, according a 2019 paper in the International Journal of Environmental Research and Public Health. Although this study concentrated on the direct use of essential oils instead of ambient scent, it implies that the chemicals generated by a cut lemon might have some air-purifying properties. Though these research mostly focussed on essential oils or concentrated versions of lemon aroma, they offer a scientific basis for knowledge on why the "lemon by your bed" habit might have some worth. Particularly considering a cut lemon near the bed overnight, more study is required to completely grasp the benefits of whole lemon aromatherapy on sleep and general wellness.
