Can Plants Help You Sleep Better? What the Research Shows and Understanding Real Sleep Disorders

• Meta title (56 characters): Can Plants Help You Sleep? Research and Sleep Disorder Guide
• Meta description (155 characters): See what real research says about plants and sleep quality, plus a guide to common sleep disorders and when to see a doctor.

An important distinction up front: This article covers two related but different topics. The first section looks at research on plants and general sleep quality, a supportive environmental factor. The second covers medically recognized sleep disorders, such as insomnia, sleep apnea, and narcolepsy, which require proper diagnosis and treatment from a healthcare provider. Keeping plants in your bedroom may support a calming sleep environment, but it is not a treatment for a diagnosed sleep disorder.

Plants and Sleep: What the Research Shows

Interest in plants and sleep has partly grown out of space research. Space agencies have used small greenhouses and plant-growing experiments in space stations for decades, both for practical reasons (food, air quality) and for crew well-being during long, isolated missions. Russian cosmonaut Valentin Lebedev has been widely quoted as describing a plant aboard the Salyut space station as feeling almost like a pet, reportedly placing it where he could see it before falling asleep. This kind of anecdote reflects a broader, genuine interest from space agencies in how plants affect crew well-being during extended isolation.

A Real Study on Plants and Sleep in Isolated Environments

Researchers at Beihang University in Beijing studied how interacting with different edible plants — coriander, strawberry, and purple mustard flower (rapeseed flower) — affected mood and sleep in a simulated long-duration isolated environment, the kind relevant to deep-space or deep-sea missions. Using saliva samples (to measure cortisol) and sleep monitoring, they found:

• Strawberry plants had the strongest positive effect on participants’ mood.
• Coriander, specifically, was linked to falling asleep faster and more consolidated, higher-quality sleep (fewer micro-awakenings during the night).
• There appeared to be a combined benefit from pairing certain plants with specific light conditions, suggesting the light environment and plant choice may work together.

This is a genuinely interesting, real study, but it’s worth keeping its scope in mind: it was conducted in a simulated isolation setting relevant to space and extreme environments, with a specific small set of plants. It doesn’t mean any green plant will reliably improve sleep for everyone in an ordinary bedroom, but it does offer a reasonable, evidence-based starting point.

Other Supporting Research

Separately, a study from Sichuan Agricultural University found that looking at a potted bamboo plant for just three minutes had a measurable calming effect, including modest reductions in blood pressure and self-reported anxiety. Other research on viewing plants more broadly has found reductions in heart rate and salivary cortisol after short exposure, suggesting that simply observing greenery, not just actively gardening, can have a calming physiological effect.

There’s also reasonable evidence that pleasant scents, including those from some aromatic and edible plants, can have a relaxing effect through aromatherapy-like mechanisms, which is why scented plants like lavender are commonly recommended for bedrooms, even though lavender wasn’t part of the specific study above.

How to Use Plants to Support Better Sleep

Based on this research, a few reasonable, low-cost approaches:

Keep a plant in your bedroom. Simply having greenery in your sleeping space may contribute to a calmer environment.

Interact with your plants regularly, not just visually. Watering, touching, and smelling plants, especially before bed, may enhance the calming effect beyond simply having them present.

Try a short “plant pause” before bed. Even a few quiet minutes with a plant, watering it, pruning it, or just sitting near it, can serve as a simple, grounding wind-down ritual, similar in spirit to other mindfulness practices.

Use plant interaction as a form of meditation. Moving slowly between plants while watering or pruning, or simply placing a hand near a leaf and noticing its scent, can be a gentle way to shift into a calmer state before sleep.

Consider scent. Aromatic herbs and plants like geranium are commonly recommended for this kind of practice, alongside lavender, which has more established research behind its calming properties specifically.

Which Plants Might Help Most?

Based on available research, plants worth considering include:

• Coriander, specifically studied for sleep onset and quality in the research above
• Strawberry plants, studied for mood benefits
• Lavender, more broadly studied for calming and sleep-supportive properties
• Other pleasantly scented plants, such as jasmine or geranium, often recommended based on general aromatherapy research

Claims about specific plants like snake plants, dracaena, or rubber trees directly improving deep sleep stages circulate online, but I wasn’t able to verify these against solid, peer-reviewed research, so I’d treat them as unconfirmed rather than established. Snake plants are still a great low-maintenance bedroom plant for other reasons (easy care, attractive, tolerates low light), just not on strong sleep-specific evidence.

Understanding Sleep Disorders

Plants and a calming bedroom environment are helpful supportive habits, but they’re not a treatment for a diagnosed sleep disorder. If you consistently struggle with sleep, it’s worth understanding what might be going on medically.

How common is poor sleep? The CDC has reported that roughly a third of U.S. adults regularly get less than the recommended seven hours of sleep per night, and a large majority of U.S. high school students (CDC survey data has put this above 70% in recent years) report getting less sleep on school nights than recommended for their age group.https://www.cdc.gov/sleep/data-research/facts-stats/index.html

Common Types of Sleep Disorders

Insomnia: Difficulty falling or staying asleep, which can stem from stress, anxiety, hormonal changes, jet lag, or an underlying medical condition. Insomnia is generally classified as:

• Chronic: occurring regularly for a month or longer
• Intermittent: occurring on and off
• Transient: lasting just a few nights

Estimates of how many adults experience insomnia at some point in their lives vary by study and definition, but it’s considered common, and it’s more frequently reported in older adults and in women. If insomnia persists for weeks or significantly affects your daily functioning, it’s worth discussing with a doctor rather than assuming it will resolve on its own.

Sleep apnea: A serious condition involving repeated pauses in breathing during sleep, which reduces oxygen intake and can cause frequent waking. There are two main types:

• Obstructive sleep apnea, caused by a blocked or narrowed airway
• Central sleep apnea, caused by a disruption in the brain’s signal to the breathing muscles

Sleep apnea requires proper diagnosis and medical treatment and should never be managed with home remedies alone, given its association with serious cardiovascular risks if left untreated.

Parasomnias: Unusual behaviors during sleep, including sleepwalking, sleep talking, nightmares, bedwetting, and teeth grinding or jaw clenching.

Restless legs syndrome (RLS): An uncomfortable urge to move the legs, sometimes with a tingling sensation, that’s typically worse at night. It’s associated with certain conditions, including ADHD and Parkinson’s disease, though the exact cause isn’t always identifiable.

Narcolepsy: A neurological condition causing sudden, overwhelming sleepiness and sleep episodes during waking hours, sometimes accompanied by sleep paralysis. It can occur on its own or alongside other neurological conditions.

Common Symptoms of Sleep Disorders

• Difficulty falling or staying asleep
• Daytime fatigue or a strong urge to nap
• Unusual breathing patterns during sleep
• Uncomfortable urges to move, especially at night
• Unusual movements or behaviors during sleep
• Irritability, poor concentration, or low mood
• Difficulty functioning at work or school

What Causes Sleep Disturbances?

Several underlying factors can disrupt sleep:

• Allergies and respiratory issues, which can make nighttime breathing more difficult
• Frequent nighttime urination (nocturia), sometimes linked to hormonal or urinary tract issues; seek medical attention if it’s accompanied by pain or bleeding
• Chronic pain, including from arthritis, fibromyalgia, inflammatory bowel disease, or persistent headaches, which can both cause and be worsened by poor sleep
• Stress and anxiety, a very common contributor to both difficulty falling asleep and staying asleep

How Sleep Disorders Are Diagnosed

A doctor typically starts with a physical exam and a review of your symptoms and medical history, and may order further testing, such as:

• Polysomnography (PSG): An overnight, lab-based sleep study measuring oxygen levels, body movement, and brain activity
• Home sleep testing (HST): Often used specifically to evaluate for sleep apnea
• Electroencephalogram (EEG): Measures brain electrical activity
• Multiple Sleep Latency Test (MSLT): Used specifically to help diagnose narcolepsy

Treatment Approaches

Treatment depends entirely on the specific diagnosis and generally works best alongside lifestyle changes. Options can include:

• Prescription sleep medications, when appropriate
• Melatonin supplements, generally considered reasonable for short-term, occasional use, though it’s still worth checking with a doctor, especially for regular use
• Treatment for underlying allergies or illness contributing to poor sleep
• CPAP therapy or, in some cases, surgery, for sleep apnea
• Dental splints for teeth grinding or jaw clenching
• Cognitive behavioral therapy for insomnia (CBT-I), which has strong evidence as a first-line treatment for chronic insomnia specifically https://aasm.org/new-guideline-supports-behavioral-psychological-treatments-for-insomnia/

Frequently Asked Questions

Can houseplants cure insomnia or sleep apnea?
No. Plants may support a calmer bedroom environment and general sleep quality, but they are not a treatment for diagnosed sleep disorders, which require proper medical evaluation.

Which plant is best for sleep based on research?
Coriander showed specific sleep-quality benefits in a controlled study of isolated environments, and lavender has broader research support for calming and sleep-supportive effects. Many other popular “sleep plant” claims circulating online aren’t well supported by strong evidence.

When should I see a doctor about sleep problems?
If sleep difficulty persists for several weeks, significantly affects your daily functioning, or is accompanied by symptoms like loud snoring with gasping (possible sleep apnea), sudden daytime sleep episodes, or an urge to move your legs at night, it’s time for a medical evaluation rather than relying on home remedies.

Is melatonin safe to use regularly?
Melatonin is generally considered reasonable for short-term or occasional use, but regular long-term use should be discussed with a doctor, since it’s a hormone and can interact with the body’s natural sleep-wake regulation in ways that aren’t fully understood with chronic use.

The Bottom Line

Real research supports the idea that certain plants, interacted with before bed, may offer modest benefits for sleep onset and overall sleep quality, likely through a combination of calming scent, visual greenery, and a simple, grounding bedtime ritual. This makes plants a reasonable, low-cost addition to a healthy sleep routine. But they are a complement to good sleep habits, not a substitute for proper diagnosis and treatment if you’re dealing with a genuine sleep disorder like insomnia, sleep apnea, or narcolepsy.
