When it comes to getting better sleep, we often focus on things like avoiding screens, taking melatonin, or investing in a better mattress. But one powerful—and often overlooked—tool in the sleep toolkit is aromatherapy. This ancient practice uses natural plant extracts, or essential oils, to promote health and well-being. And when it comes to sleep, the right scents can have a profound calming effect on both body and mind.

So how exactly does aromatherapy help with sleep, and which scents work best? Let’s dive in.

How Aromatherapy Works for Sleep

Your sense of smell is directly connected to your brain’s limbic system—the area that controls emotions, memories, and behaviors. When you inhale certain essential oils, they can trigger a cascade of calming neurochemical responses, like the release of serotonin or a decrease in cortisol (the stress hormone). This can lower anxiety, reduce restlessness, and create the ideal conditions for sleep.

In essence, aromatherapy helps “set the stage” for your body to wind down, making it easier to fall asleep and stay asleep.

Best Essential Oils for Sleep

1. Lavender

Lavender is the superstar of sleep aromatherapy. Studies have shown that it:

• Increases deep (slow-wave) sleep

• Lowers heart rate and blood pressure

• Reduces anxiety and promotes calmness

How to use: Add a few drops to a diffuser, sprinkle on your pillow, or apply a diluted form to your wrists or temples before bed.

2. Chamomile

Roman chamomile essential oil has mild sedative effects and is known to soothe nervous tension. It’s especially good if your sleeplessness is due to stress or emotional distress.

How to use: Diffuse in your bedroom or add a few drops to a warm bath before bedtime.

3. Bergamot

Though it’s a citrus oil, bergamot has calming rather than energizing properties. It helps reduce heart rate and blood pressure, and it may help quiet an anxious mind.

How to use: Inhale through a diffuser or apply to the chest (diluted with a carrier oil).

4. Cedarwood

Cedarwood oil contains compounds that stimulate the pineal gland, which helps your body produce melatonin naturally. It’s grounding and promotes a sense of stillness.

How to use: Add to a nighttime diffuser blend or apply to the soles of your feet.

5. Ylang Ylang

This sweet, floral oil has a sedative effect and can slow the heart rate. It's great for people whose insomnia is driven by nervous system overactivity.

How to use: Mix a few drops with a carrier oil and rub onto your chest or neck, or blend with lavender in a diffuser.

How to Use Aromatherapy for Better Sleep

• Diffuser: Add 5–10 drops of your chosen essential oil to a water-based diffuser and run it for 30–60 minutes before bed.

• Pillow Spray: Mix essential oil with water and a little witch hazel in a spray bottle to lightly mist your pillow or sheets.

• Topical Application: Dilute essential oils with a carrier oil (like coconut or jojoba) and apply to pulse points, neck, or feet.

• Bath Soak: Add a few drops of essential oil to Epsom salts, then dissolve in a warm bath to relax both muscles and mind.

• Inhalation: Put a drop or two on a tissue, cotton ball, or lava bead bracelet and inhale gently as you wind down.

Safety Tips

• Always dilute essential oils before applying to the skin.

• Avoid ingesting oils unless under the care of a qualified health provider.

• Use caution if pregnant, breastfeeding, or managing health conditions.

• Do a patch test to check for skin sensitivity.
