How Sleep Positions May Reflect Your Mental Health

Scrolling through TikTok lately, you may have come across claims that your sleep position whether curled like a baby or sprawled like a mountain climber reveals hidden truths about your emotional state. According to some of these videos, specific positions reflect nervous system activation, high stress, or even repressed trauma.

But are these claims backed by science?

Experts say probably not. While it’s tempting to decode mental health clues from the way you sleep, current research points to something even more important than position: sleep quality. And when it comes to your mental health, how well you sleep may reveal far more than the position you fall asleep in.

The Truth About Sleep Positions and Mental Health

The idea that your sleep posture reflects your emotional health has been around for decades. One often-cited study from the 1970s attempted to link sleep positions with personality traits but its findings haven’t been replicated in large-scale, modern studies.

“There’s little strong evidence linking specific sleep positions to mental health conditions,” says Bruce Tammelin, MD, medical director of Providence St. Joseph Hospital Sleep Disorders Center. In fact, most of the recent scientific research has focused on how stress impacts sleep, rather than what your sleep position might reveal about your psychological state.

That said, your posture could influence your physical health for instance, sleeping on your side may help the brain more efficiently clear waste, potentially reducing the risk of neurodegenerative diseases like Alzheimer’s.

The Real Connection: Stress and Sleep

The most significant and well-supported connection between sleep and mental health is how chronic stress affects the body’s ability to rest.

Here’s how it works:

• When you're under stress, your body activates the HPA axis (hypothalamic-pituitary-adrenal axis), triggering the release of cortisol, the body’s primary stress hormone.

• Cortisol helps regulate metabolism and inflammation, but it also interferes with melatonin, the hormone responsible for making you sleepy.

• Elevated cortisol levels in the evening can delay sleep onset, fragment your rest, and reduce overall sleep quality.

• This leads to a cycle of poor sleep and increased stress, which can worsen anxiety, depression, and physical health symptoms.

In fact, studies show that people with insomnia or fragmented sleep are more likely to experience mental health struggles, and treating sleep disorders often improves symptoms of depression and anxiety.

Mental Health and Common Sleep Disorders

Sleep and mental health share a complex, bidirectional relationship. Research has found that sleep disorders are significantly more common in individuals experiencing mental health issues, including:

• Insomnia

• Sleep apnea

• Nightmares or night terrors

• Restless leg syndrome

• Narcolepsy

Neurodivergent individuals, especially those with ADHD, may experience additional challenges, such as:

• Low nighttime melatonin levels

• Sensory processing issues

• A hyperactive nervous system

These factors can make winding down before bed even more difficult adding to emotional strain and daytime fatigue.

Stress-Related Sleep Behaviors

While your sleep position may not reveal your mental state, certain nighttime behaviors might reflect stress in the moment. For example:

• Teeth grinding

• Covering your ears while sleeping

• Sleepwalking or night terrors

“These may be signs of an activated nervous system during sleep,” says Kyoungbin K. Im, MD, a psychiatrist and sleep medicine specialist at UC Irvine. However, they don’t always reflect daytime stress they may stem from physiological responses occurring during specific sleep phases.

How to Improve Sleep When You’re Stressed

If you’ve been struggling to fall or stay asleep, a few simple changes can help calm your mind and support more restorative rest.

Try these evidence-backed tips:

• Keep your bedroom for sleep only: Remove work, phones, or anything mentally stimulating from the space.

• Wind down gradually: Avoid screens, caffeine, and intense workouts at least three hours before bedtime.

• Practice progressive muscle relaxation: Gently tense and release muscles, starting from your toes and working upward.

• Stay consistent: Aim to go to bed and wake up at the same time every day even on weekends.

• Create a calming ritual: Try reading, taking a warm shower, or listening to soft music.

Quick stat: According to the CDC, 1 in 3 adults doesn’t get enough sleep, and poor sleep is now recognized as a major public health issue linked to mental illness, obesity, and chronic disease.

Bottom Line

There’s little evidence that your sleep position reflects your emotional well-being but your sleep quality absolutely does. Chronic stress can interfere with your ability to fall and stay asleep, which in turn can increase anxiety and depression.

Focusing on consistent, calming bedtime habits and getting help for persistent sleep issues may be one of the most impactful steps you can take for both your mental health and overall wellness.
