Vertigo When Lying Down? BPPV Causes, Symptoms & Treatment

Vertigo

May 5

If you feel like the room is spinning when you lie down, roll over in bed, sit up, or look up, you're probably wondering why something as simple as changing position can suddenly trigger intense vertigo.

One of the most common causes is benign paroxysmal positional vertigo, or BPPV.

BPPV is a problem involving the inner ear's balance system, and it is often very treatable when the correct diagnosis is made.

But not all positional dizziness is BPPV.

Understanding what is causing your vertigo is the first step toward treating it effectively.

What Is Vertigo?

Vertigo is the sensation that you or your surroundings are spinning, moving, or tilting when they aren't actually moving.

It is different from simply feeling lightheaded or unsteady.

Vertigo can feel like:

The room is spinning
You are being pulled or tilted
The bed is moving underneath you
You are falling or rolling
Your head is suddenly being thrown off balance

It may also be accompanied by:

Nausea
Motion sensitivity
Imbalance
Difficulty walking
Anxiety or a feeling that something is very wrong

When vertigo is triggered specifically by changes in head position, BPPV is one of the first conditions to consider.

Why Do I Get Vertigo When I Lie Down?

One of the most common reasons for vertigo when lying down is BPPV.

Your inner ear contains tiny calcium carbonate crystals called otoconia. These crystals normally sit in a part of the inner ear that helps detect gravity and linear movement.

Sometimes these crystals become displaced and move into one of the semicircular canals.

When you change the position of your head, the displaced crystals move inside the canal.

This sends an abnormal signal to your brain about how your head is moving.

Your eyes, inner ears, and brain are suddenly receiving conflicting information about movement—and the result can be a brief but intense spinning sensation.

That is BPPV.

What Does BPPV Feel Like?

BPPV typically causes brief episodes of vertigo triggered by specific changes in head position.

Common triggers include:

Lying down
Rolling over in bed
Getting out of bed
Looking up
Looking down
Bending over
Turning your head

The vertigo is usually brief, often lasting less than a minute, although the exact experience can vary depending on the type of BPPV.

You may also feel slightly off-balance or motion-sensitive after the spinning stops.

A classic pattern is:

You roll over in bed → the room suddenly spins → the spinning stops → you feel okay again until you move into that position again.

That pattern is highly suggestive of positional vertigo.

What Causes BPPV?

BPPV happens when the small calcium carbonate crystals in the inner ear become displaced.

This can happen for several reasons.

Sometimes there is no obvious cause.

BPPV can also occur after:

A head injury
A concussion
A fall
Rapid changes in head position
Other disturbances to the vestibular system

This is one reason BPPV is particularly important to consider after a concussion or head injury.

If your positional vertigo started after a concussion, you may have BPPV in addition to other concussion-related problems affecting your balance or visual and autonomic systems.

Is All Vertigo When Lying Down BPPV?

No.

BPPV is common, but not every episode of dizziness or vertigo is caused by BPPV.

Other possible causes include:

Vestibular migraine
Vestibular neuritis
Labyrinthitis
Persistent postural-perceptual dizziness (PPPD)
Neck-related dizziness
Other inner-ear disorders
Post-concussion vestibular dysfunction
Neurological conditions

This is why simply doing an Epley maneuver—or any other repositioning maneuver—without knowing what is causing your symptoms isn't always the best approach.

The treatment needs to match the problem.

How Is BPPV Diagnosed?

A vestibular physical therapist or other appropriately trained healthcare provider can perform specific positional tests to determine whether BPPV is present.

One of the primary tests for posterior-canal BPPV is the Dix-Hallpike maneuver.

During this test, your head and body are moved into specific positions while the clinician observes your symptoms and eye movements.

If the Dix-Hallpike test does not reproduce the expected pattern but your symptoms still suggest BPPV, additional testing may be needed, including a supine roll test to evaluate the horizontal semicircular canal.

This matters because different canals require different treatment maneuvers.

The American Academy of Otolaryngology–Head and Neck Surgery clinical practice guideline recommends appropriate positional testing and canalith repositioning for people with confirmed BPPV.

How Is BPPV Treated?

The good news is that BPPV is often very treatable.

The primary treatment is a canalith repositioning maneuver, which is designed to move the displaced crystals out of the semicircular canal and back into the part of the inner ear where they belong.

For posterior-canal BPPV, the Epley maneuver is one commonly used repositioning technique.

But the Epley maneuver isn't appropriate for every type of vertigo.

The correct maneuver depends on:

Which ear is affected
Which semicircular canal is involved
The type of BPPV
Your individual presentation

For confirmed posterior-canal BPPV, clinical guidelines strongly recommend treatment with an appropriate canalith repositioning procedure.

This is why an accurate diagnosis matters.

If the problem is BPPV, treating the correct canal can often provide significant improvement.

If the problem isn't BPPV, repeatedly performing repositioning maneuvers isn't going to address the underlying cause.

Should You Just Wait for BPPV to Go Away?

BPPV can sometimes resolve on its own.

However, if positional vertigo is interfering with your sleep, exercise, work, driving, or daily activities, there is no reason to simply live with it while hoping it disappears.

When BPPV is confirmed, a targeted repositioning maneuver can address the underlying mechanical problem directly.

And if your symptoms don't resolve after treatment, that is important information.

Persistent dizziness may mean:

The affected canal wasn't correctly identified
BPPV is still present
Another canal is involved
More than one condition is contributing
Something other than BPPV is causing the dizziness

The BPPV guideline recommends reassessment when symptoms persist after treatment.

Can You Treat BPPV at Home?

There are home versions of repositioning maneuvers, and they can be helpful when you have already been properly diagnosed and know which maneuver is appropriate for your particular type of BPPV.

The problem is that positional vertigo can have different causes and different patterns.

If you aren't sure whether you have BPPV—or which canal is involved—doing random maneuvers from the internet may not address the actual problem.

It's much more useful to determine the cause first and then treat it specifically.

When Vertigo May Be Something More Than BPPV

Positional vertigo should be evaluated more carefully if:

Your dizziness is constant rather than triggered by position
Episodes last much longer than expected for typical BPPV
You have new neurological symptoms
You experience double vision
You have difficulty speaking
You have significant new weakness or numbness
You develop a sudden, severe headache
You have new significant hearing changes
Your symptoms don't fit the typical pattern of BPPV

These symptoms don't necessarily mean something serious is happening, but they don't fit the straightforward BPPV pattern and warrant appropriate medical evaluation.

What If My Vertigo Started After a Concussion?

This is especially important.

BPPV can occur after head trauma, including concussion.

But post-concussion dizziness isn't always caused by BPPV.

After a concussion, dizziness can involve several different systems, including:

The vestibular system
Vision
The autonomic nervous system
The neck
Migraine mechanisms
Balance and sensory integration

You may even have BPPV plus another contributor to your dizziness.

That's why simply treating the crystals may not completely resolve dizziness after a concussion.

If your dizziness began after a concussion, a comprehensive vestibular evaluation can help determine what is actually contributing to your symptoms.

Why Am I Dizzy After a Concussion? Causes and What Actually Helps

Why Vestibular Physical Therapy Can Help

A vestibular physical therapist can do more than simply perform an Epley maneuver.

An evaluation can help determine:

Whether BPPV is present
Which ear and canal are involved
Whether another vestibular problem is contributing
Whether vision is contributing to your symptoms
Whether your neck may be involved
Whether balance or sensory integration is impaired
Whether your symptoms fit a post-concussion pattern

If BPPV is confirmed, the appropriate repositioning maneuver can be performed.

If BPPV isn't the whole story, treatment can address the other factors contributing to your dizziness.

The goal isn't simply to make you feel less dizzy temporarily. It's to determine why you're dizzy and treat the underlying problem.

Frequently Asked Questions About Vertigo When Lying Down

Why do I get vertigo when I lie down?

One of the most common causes is BPPV, which occurs when displaced inner-ear crystals move within a semicircular canal and create abnormal signals about head movement.

Why do I get vertigo when I roll over in bed?

Rolling over changes the position of your head and can cause displaced inner-ear crystals to move, triggering the brief spinning sensation characteristic of BPPV.

How long does BPPV vertigo last?

The spinning sensation associated with BPPV is typically brief and triggered by a particular position. It often lasts less than a minute, although symptoms can vary depending on the type and location of the BPPV.

Can BPPV happen after a concussion?

Yes. Head trauma can contribute to BPPV. However, dizziness after a concussion can have multiple causes, so it is important to determine whether BPPV is actually responsible for the symptoms.

Does BPPV go away on its own?

It can. However, confirmed BPPV can often be treated with a canalith repositioning maneuver rather than simply waiting for symptoms to resolve.

Is the Epley maneuver always the right treatment?

No. The appropriate maneuver depends on the type and location of the BPPV. That's why identifying the affected canal is important before choosing a treatment maneuver.

Can a physical therapist treat BPPV?

Yes. Physical therapists with vestibular training can evaluate and treat BPPV using positional testing and appropriate canalith repositioning maneuvers.
