Overview
What is it?
Aromatherapy is a natural, holistic therapy that uses essential oils extracted from plants to promote physical and emotional well-being. It is often used as a complementary treatment alongside conventional medicine to address conditions like pain, anxiety, depression, and insomnia. Essential oils are naturally occurring aromatic compounds that can be inhaled, applied to the skin, or used in diffusers to create a calming environment .
How does it work?
Aromatherapy works by stimulating the olfactory system (sense of smell) and other pathways in the body. When essential oils are inhaled, their molecules interact with the brain's limbic system, which regulates emotions, stress, and sleep. This interaction can trigger the release of neurotransmitters like endorphins, promoting relaxation and reducing anxiety, which can help improve sleep quality. Essential oils can also be absorbed through the skin during massage, further enhancing their calming effects .
What are the benefits?
Aromatherapy is particularly beneficial for improving sleep quality and managing insomnia. Essential oils like lavender are widely used for their calming and sedative properties, which can help reduce stress and anxiety, making it easier to fall asleep and stay asleep. Research suggests that aromatherapy can regulate blood pressure and heart rate, further promoting relaxation and better sleep .
Effectiveness
What does the research say?

Studies have shown that inhaling lavender oil can reduce sleep disturbances and improve sleep patterns. However, the evidence is mixed in some populations, such as those with dementia, where the benefits of aromatherapy for sleep are less clear .
