OLFACTORY INTERVENTIONS FOR SLEEP ENHANCEMENT: A REVIEW

Abstract

Sleep is essential for cognitive function, emotional balance, and overall well-being. Disruptions like insomnia or poor sleep quality can have negative consequences. Various methods, including bedtime perfumes, have been studied to improve sleep. This review examines the scientific basis of scent-based sleep enhancement, focusing on the olfactory system and the effects of specific aromatic compounds on sleep. The olfactory system plays a crucial role in how scents influence sleep. Odor molecules bind to receptors in the nasal cavity, sending signals to the olfactory bulb, which processes these signals and relays them to the limbic system. This connection allows scents to evoke emotional responses and impact sleep. Historically, scent therapy has been used across cultures. The effectiveness of bedtime perfumes depends on their delivery methods. Diffusers, sprays and roll-on oils are common ways to disperse essential oils. Incorporating these perfumes into comprehensive sleep hygiene routine, including a consistent sleep schedule and a calming environment, maximizes their benefits. Future research should identify specific scent compounds that induce sleep, explore the interaction between olfactory stimuli and sleep stages and investigate the long-term safety and efficacy of bedtime perfumes. In conclusion, bedtime perfumes can improve sleep quality through the power of scent. Understanding olfactory pathways, calming scents and the historical context of scent therapy helps individuals make informed choices about using these fragrances.
