Essential oils have a powerful effect on the brain and nervous system through the olfactory nerve. Each essential oil usually contains about 100 chemicals that act on the whole body. Essential oils work on the body and mind, helping to relax, reduce fatigue, anxiety, thereby bringing sleep easier and deeper. Aromatherapy aromatherapy is a seemingly modern term but has been around for thousands of years. And for many years, scientists have been conducting studies of essential oils' sleep-promoting, stress-relieving, pain-relieving and mood-regulating benefits.

Essential oils for sleep are divided into two main categories: soothing mood, reducing anxiety and reducing congestion, and reducing snoring. According to studies done show that taking essential oils before bed can improve the quality of sleep and especially does not cause the side effects that affect the body like taking sleeping pills.

Essential oils suitable for the bedroom are usually those with a warm, sweet scent to help the body relax, sedate and easier to fall asleep. A study published in the British medical journal Lancet showed that elderly patients will sleep well like children when lightly putting lavender oil, sandalwood, rose, ... into the bedroom at night. These patients often have difficulty falling asleep and require sleeping pills.
