Does Lavender Help You Sleep? What Research Says
You've probably seen lavender everywhere — in pillow sprays, bath salts, candles, and sleep-focused skincare. But does it actually work, or is it just clever marketing? The short answer: the research is more convincing than you might think. And the way you use lavender matters a lot.
Here's what the science says, and how to build a wind-down routine that puts it to work for you tonight.
What Does the Research Actually Show About Lavender and Sleep?
Lavender's active compounds — primarily linalool and linalyl acetate — interact with the nervous system in ways that promote calm. Multiple peer-reviewed studies have found that inhaling lavender before sleep reduces sleep latency (the time it takes to fall asleep), improves sleep quality scores, and lowers nighttime waking.
A widely cited study published in the Journal of Alternative and Complementary Medicine found that lavender aromatherapy significantly improved sleep quality in college students. Similar results have been replicated in hospital patients, shift workers, and people with mild anxiety-related insomnia.
It's not a sedative — lavender doesn't knock you out. What it does is reduce sympathetic nervous system activity, which is the "fight or flight" mode that keeps many of us wired at night. Think of it as helping your body take the foot off the accelerator.
Is Lavender Effective When Applied to Skin?
Yes. Topical application has also shown promise, especially when combined with massage or a warm shower. The heat helps open pores and increases absorption, while the steam carries the scent directly to your airways. That's why a pre-sleep shower with a lavender-based product is one of the most effective delivery methods — you're getting both topical and aromatic benefits at once.
Rested's Sleep Body Wash is built around exactly this mechanism. Lavender is paired with magnesium — another well-researched sleep support mineral — to give your body two calming signals at once.
How to Use Lavender for Sleep: What Actually Works
1. Timing Is Everything
Using lavender randomly throughout the day won't do much. The research consistently shows benefits when lavender is used 30–60 minutes before bed. This is when your body is starting to shift into sleep mode — melatonin is rising, body temperature is dropping — and lavender can support that process rather than fight against it.
Build it into a consistent pre-sleep ritual. Consistency is what turns a nice shower into a genuine sleep cue.
2. Combine Scent With Sensory Wind-Down
The most effective sleep routines don't rely on one thing — they stack multiple calm signals together. Scent, warmth, darkness, and stillness all work on different parts of the nervous system. When you combine them, the effect compounds.
That's why we recommend pairing the Sleep Body Wash with the Dawn Silk Sleep Mask. Start with a warm shower using the Body Wash — let the lavender and magnesium do their work. Then slip on the silk mask as you get into bed to block out every bit of light. You've addressed scent, touch, warmth, and darkness in one simple sequence. That's a proper wind-down.
The Dawn Silk Sleep Mask is made from premium mulberry silk — it sits gently on your face and lashes without pulling at skin or hair, which matters if you're doing a full skincare routine before bed. Total blackout, no pressure, no irritation.
Does Lavender Work for Anxiety-Related Sleep Problems?
This is where the research gets particularly interesting. A lot of sleeplessness isn't really a sleep problem — it's an anxiety problem that happens at night. Racing thoughts, tension in the body, an inability to switch off.
Lavender has been shown to reduce self-reported anxiety scores in clinical settings. It works on GABA receptors in the brain — the same receptors targeted by many anti-anxiety medications, though far more gently. If your sleep struggles come from a busy mind rather than a medical condition, lavender is a genuinely well-supported first step.
Combining it with magnesium — as Rested's Sleep Body Wash does — gives you an extra layer of muscle relaxation, which helps release the physical tension that often accompanies anxious thoughts.
What About Lavender for Kids?
Diluted lavender is widely used for children's sleep routines and has a good safety profile at low concentrations. That said, always check with your GP or paediatric nurse before introducing any new product to a baby's routine. For toddlers and older children, a calming bath and a dark, quiet room are still the gold standard.
What Lavender Products Are Worth Buying?
Not all lavender products are equal. Many use synthetic fragrance rather than actual lavender essential oil, which won't deliver the same benefits. Look for products that list real lavender oil in the ingredients and have a purpose-built formulation — not just a candle with lavender in the name.
Rested's Sleep Body Wash is made in Sydney with lavender and magnesium specifically for pre-sleep use. It's not a spa product that happens to smell nice — it's built around the science of sleep wind-down. The texture lathers well, rinses clean, and leaves your skin calm rather than stripped.
If you want to go further, the Sleep Balm is a topical magnesium balm you can apply after your shower — great for rubbing into the shoulders, neck, or feet before bed. Also made in Sydney.

- ☑ Get into bed and slip on your Dawn Silk Sleep Mask

That's it. Five to ten minutes, no supplements, no apps, no subscriptions. Just a sensory routine your body will start to recognise as the signal to sleep.
Frequently Asked Questions
Does lavender actually help you sleep, or is it placebo?
The research suggests it's more than placebo. Multiple controlled studies show objective improvements in sleep latency and sleep quality scores with lavender aromatherapy. That said, a consistent bedtime ritual — with or without lavender — also improves sleep. The two effects are likely additive.
How quickly does lavender work for sleep?
Most studies show effects within a single session, but benefits tend to build with consistent use over one to two weeks. Using it as part of the same nightly routine reinforces the conditioned sleep cue, which becomes stronger over time.
What Rested products contain lavender?
Rested's Sleep Body Wash is the hero lavender product — it combines lavender with magnesium for a pre-sleep shower ritual. The Sleep Balm also contains calming botanicals. Both are made in Sydney and available at rested.com.au.
Is it better to inhale lavender or apply it to skin before sleep?
Both methods have research support. A warm shower with a lavender body wash gives you both simultaneously — the steam carries the scent while your skin absorbs the actives. That makes it one of the most practical and effective delivery methods for a nightly routine.
Does Rested offer a trial period on its products?
Rested's sleep sound devices — Sounds & Stories and Sounds & Stories Mini — come with a 100-night free trial. The Sleep Body Wash and skincare products are available with free shipping on orders over $75. No subscriptions, ever.
The Bottom Line
Lavender is one of the best-researched natural sleep supports available — and unlike most sleep trends, the evidence has held up across a wide range of studies and populations. It won't replace good sleep habits, but it's a genuinely useful addition to a nightly wind-down routine.
The simplest way to use it? A warm shower with Rested's Sleep Body Wash, followed by total darkness with the Dawn Silk Sleep Mask. Scent, warmth, and darkness — three of the most powerful sleep signals working together.
