The Best Sleeping Position for Feeling Great the Next Day, According to Experts

Sleep experts reveal which sleeping position may help you wake up refreshed.

6

A good night’s sleep isn’t just about getting enough hours—it’s also about how you sleep. According to sleep specialists, your sleeping position can influence everything from spinal alignment and breathing to digestion and overall comfort.

While no single position is perfect for everyone, experts agree that some sleeping postures may offer more benefits than others when it comes to waking up feeling refreshed and pain-free.

Why Sleeping Position Matters

The body spends roughly one-third of life sleeping. During that time, muscles relax, joints recover, and the brain processes information from the day.

If the spine, neck, or shoulders are placed in an awkward position for hours at a time, discomfort can build overnight and lead to stiffness, headaches, or fatigue the next morning.

A supportive sleeping posture helps maintain natural spinal alignment, reduces pressure points, and may improve sleep quality.

Side Sleeping Is Often Recommended

Many sleep specialists consider side sleeping one of the healthiest positions for most adults.

Sleeping on your side can:

• Help keep airways more open
• Reduce snoring in some people
• Promote better spinal alignment
• Ease pressure on the lower back
• Support healthy digestion

Some research also suggests that sleeping on the left side may provide additional benefits for certain individuals, particularly those dealing with acid reflux or digestive discomfort.

However, side sleepers should use a pillow that keeps the neck aligned with the spine to avoid shoulder and neck strain.

What About Sleeping on Your Back?

Back sleeping is often praised for promoting even weight distribution and neutral spinal positioning.

Potential benefits include:

• Reduced pressure on joints
• Better spinal support
• Less facial compression during sleep
• Improved posture maintenance

Experts generally recommend placing a pillow beneath the knees to help preserve the natural curve of the lower back.

However, back sleeping may not be ideal for everyone. It can sometimes worsen snoring and may contribute to breathing disruptions in certain individuals.

Is Sleeping on Your Stomach a Good Idea?

Although some people find stomach sleeping comfortable, experts often rank it as the least favorable position for long-term comfort.

Potential drawbacks include:

• Increased neck strain
• Pressure on the lower back
• Greater likelihood of waking with soreness
• Difficulty maintaining spinal alignment

Because the head must remain turned to one side for extended periods, neck discomfort can become a common issue among stomach sleepers.

Still, comfort remains important. If this position helps someone sleep deeply and consistently, small adjustments such as supportive pillows may help reduce strain.

The Importance of Pillow and Mattress Support

Even the best sleeping position can become uncomfortable without proper support.

A quality mattress and pillow can help:

• Maintain spinal alignment
• Reduce pressure points
• Improve overall comfort
• Minimize tossing and turning

Sleep experts often recommend replacing worn-out pillows and evaluating mattress quality if persistent aches or poor sleep continue.

There Is No One-Size-Fits-All Answer

Despite common recommendations, experts emphasize that individual needs vary.

Factors such as:

• Existing back or neck pain
• Pregnancy
• Sleep apnea
• Acid reflux
• Personal comfort preferences

can all influence which position works best.

The most effective sleeping position is often the one that allows a person to sleep comfortably, breathe easily, and wake feeling rested without pain.

The Bottom Line

Many experts consider side sleeping—particularly with proper pillow support—one of the best overall sleeping positions for adults. Back sleeping may also offer significant benefits when spinal alignment is maintained, while stomach sleeping tends to place more strain on the neck and back.

Ultimately, the ideal sleeping position is the one that supports your body’s needs and helps you achieve consistent, restorative sleep night after night.

The Best Sleeping Position for Waking Up Refreshed, According to Sleep Experts

Have you ever gone to bed feeling exhausted, slept for seven or eight hours, and still woken up with a stiff neck, an aching back, or the feeling that you barely rested at all?

You may have blamed stress, a busy schedule, or simply getting older. But another factor could be contributing to your discomfort: the way you position your body while you sleep.

Sleep is essential for physical recovery, emotional well-being, memory, and concentration. Yet the number of hours you spend in bed is only part of the picture. Your sleeping environment, mattress, pillow, underlying health conditions, and sleeping position can all influence how comfortable you feel throughout the night.

Sleep specialists generally agree that there is no single sleeping position that is best for everyone. However, side sleeping and back sleeping can each offer advantages, depending on your individual needs. Stomach sleeping may place additional strain on the neck and back, particularly if your pillow or mattress does not provide appropriate support.

Understanding these differences can help you make small adjustments that may improve your comfort and help you wake up feeling more refreshed.

Why Your Sleeping Position Matters More Than You Think

During sleep, your body continues to perform essential functions. Muscles recover, tissues undergo repair, and the brain processes information acquired throughout the day.

Although your body is resting, the position you maintain for hours can influence the pressure placed on your neck, shoulders, hips, and lower back.

Imagine sleeping with your head tilted sharply to one side for an entire night. You might wake up with tight neck muscles or difficulty turning your head comfortably.

Similarly, if your lower back is held in an uncomfortable position for hours, you may notice stiffness when you first get out of bed.

A supportive sleeping position aims to keep your head, neck, and spine in a reasonably neutral alignment while reducing unnecessary pressure on sensitive areas.

However, alignment is not the only consideration.

Your breathing can also change with your sleeping position. Some people snore more when lying on their backs, while others experience worsening acid reflux when they lie flat.

People with chronic pain, pregnancy-related discomfort, or certain medical conditions may benefit from specific positioning strategies.

The goal is not to force your body into a supposedly perfect posture. It is to find a comfortable position that supports your health, allows you to sleep well, and does not leave you feeling worse in the morning.

1. Side Sleeping: A Practical Choice for Many Adults

<text color=”secondary” size=”sm”>Often useful for people who snore, experience acid reflux, or want to reduce strain on their lower back.</text>

Side sleeping is one of the most common sleeping positions, and for many adults, it can be a comfortable option.

When positioned properly, sleeping on your side may help keep your spine aligned and reduce certain breathing problems associated with lying flat on your back.

It can also be adjusted easily with pillows to support the neck, hips, and knees.

Potential benefits of side sleeping

It may reduce snoring.

For some people, lying on the back allows the tongue and soft tissues of the throat to move backward, narrowing the airway. This can contribute to snoring and may worsen obstructive sleep apnea.

Sleeping on either side can reduce these position-related breathing problems in some individuals.

However, side sleeping does not eliminate every cause of snoring or sleep apnea. People who experience loud habitual snoring, pauses in breathing, or excessive daytime sleepiness should seek medical evaluation rather than relying on position changes alone.

It may improve spinal comfort.

Side sleeping can be comfortable for people who experience lower-back discomfort, especially when the knees are slightly bent and the spine is kept relatively straight.

A pillow between the knees may help prevent the upper leg from pulling the pelvis forward and twisting the lower back.

The head pillow is equally important. If it is too low, the head may drop toward the mattress. If it is too high, the neck may bend upward.

Ideally, the pillow should fill the space between your shoulder and head so your neck remains aligned with the rest of your spine.

It may help with acid reflux.

For people who experience gastroesophageal reflux, sleeping on the left side may reduce nighttime reflux symptoms compared with sleeping on the right side or lying flat on the back.

This is one reason left-side sleeping is often suggested for people who experience heartburn at night.

Raising the head of the bed can also help some people with nighttime reflux. Simply stacking several pillows under the head may not provide the same benefit and can sometimes create an uncomfortable bend at the waist or neck.

How to sleep comfortably on your side

Try these simple adjustments:

• Choose a pillow that keeps your head level rather than tilted up or down.
• Keep your shoulders and hips comfortably aligned.
• Bend your knees slightly instead of curling tightly into a ball.
• Place a pillow between your knees if it helps your hips and lower back feel more comfortable.
• Avoid placing your arm beneath your head in a way that causes shoulder pressure or numbness.

You do not necessarily need to sleep on your left side every night. If you are healthy, comfortable, and sleeping well on your right side, there may be no reason to change.

The best side is often the one that supports your particular needs.

2. Back Sleeping: Helpful for Spinal Support, but Not for Everyone

<text color=”secondary” size=”sm”>Often comfortable for people who want to distribute pressure evenly and support the natural curve of the spine.</text>

Back sleeping involves lying flat on your back with your face directed toward the ceiling.

Some sleep and pain specialists recommend this position for people who find that it reduces pressure on their spine and joints.

Because your weight is distributed across a relatively broad area, back sleeping may help some people maintain a comfortable, symmetrical posture.

But there is an important qualification: what feels good for one person may aggravate another person’s symptoms.

Potential benefits of back sleeping

It may help maintain spinal alignment.

When your head is supported appropriately and your legs are positioned comfortably, back sleeping can help maintain the natural curves of your spine.

For some people with lower-back pain, placing a small pillow beneath the knees reduces tension in the lower back and makes it easier to relax.

It may reduce pressure on the shoulders and hips.

Side sleeping places more direct pressure on the shoulder and hip against the mattress. Back sleeping can reduce this pressure for people who find those areas uncomfortable.

However, individual results vary. People with certain shoulder, neck, or spinal conditions may find back sleeping less comfortable.

It avoids prolonged head rotation.

Unlike stomach sleeping, back sleeping does not require the head to remain turned to one side for breathing.

This can be helpful for people whose neck discomfort is aggravated by sustained rotation.

Why back sleeping may be unsuitable for some people

The most important limitation is its effect on breathing.

For some people, particularly those with obstructive sleep apnea, lying on the back can allow soft tissues in the throat to narrow the airway. This may increase snoring and breathing interruptions.

Back sleeping may also aggravate nighttime acid reflux in some individuals.

If you regularly wake up gasping, have witnessed pauses in breathing during sleep, experience morning headaches, or feel unusually sleepy during the day, discuss these symptoms with a healthcare professional.

Changing sleeping position may help certain people, but it is not a substitute for appropriate diagnosis and treatment.

How to make back sleeping more comfortable

If you prefer sleeping on your back, consider the following:

• Use a pillow that supports your neck without pushing your chin toward your chest.
• Place a small pillow beneath your knees if it eases lower-back tension.
• Keep your shoulders relaxed rather than raised toward your ears.
• Avoid forcing yourself to sleep on your back if it worsens pain, snoring, or reflux.

Back sleeping can be a good choice for some adults, but comfort and breathing quality should guide your decision.

3. Stomach Sleeping: Comfortable for Some, Challenging for Others

<text color=”secondary” size=”sm”>May be comfortable for certain people, but often places additional strain on the neck and lower back.</text>

Stomach sleeping, also called prone sleeping, involves lying face down on the mattress.

Some people naturally prefer this position and find it easier to fall asleep this way.

However, stomach sleeping can be difficult to maintain without placing the neck in an awkward position.

Because you cannot comfortably breathe with your face directly against the mattress, you generally need to turn your head to one side. Holding that position for hours can strain the neck.

The lower back may also become uncomfortable, particularly if the mattress allows the abdomen to sink too deeply.

Potential disadvantages of stomach sleeping

It can strain the neck.

Keeping the head rotated for an extended period may aggravate neck stiffness or existing neck pain.

It may increase lower-back discomfort.

Depending on body shape and mattress support, stomach sleeping can increase the arch of the lower back and make some people uncomfortable.

It can place pressure on the shoulders.

Some stomach sleepers extend their arms overhead or twist their shoulders into uncomfortable positions. This may aggravate shoulder pain or cause morning stiffness.

If you cannot sleep in any other position

You do not necessarily need to panic if you naturally sleep on your stomach and wake up feeling well.

However, if you experience frequent neck or back pain, it may be worth experimenting with another position.

If you continue sleeping on your stomach, a relatively thin pillow—or no head pillow if comfortable—may reduce the amount your neck bends backward. A thin pillow beneath the lower abdomen may also help some people reduce lower-back strain.

These adjustments are not suitable for everyone, and they should not cause additional discomfort.

The important principle is simple: do not sacrifice comfortable breathing or tolerate persistent pain just to maintain a particular sleeping position.

4. Should You Sleep on Your Left Side or Your Right Side?

You may have heard that sleeping on the left side is always healthier than sleeping on the right.

The truth is more nuanced.

Both positions can be comfortable and appropriate for many adults. The better choice depends on your symptoms, health conditions, and personal comfort.

Left-side sleeping

Left-side sleeping may be particularly useful for people with nighttime acid reflux.

Some people also find it comfortable during pregnancy, although pregnancy-specific guidance becomes increasingly important as pregnancy progresses.

Right-side sleeping

Right-side sleeping is a reasonable option for many people who sleep comfortably this way.

Some people may prefer it because of shoulder pain, personal habit, or other comfort considerations.

For people with acid reflux, however, right-side sleeping may aggravate symptoms compared with left-side sleeping.

Do you need to switch sides during the night?

Not necessarily.

If you wake up naturally and want to change positions, there is usually no need to resist the movement.

If you have shoulder or hip pain, alternating sides may help reduce prolonged pressure on one area. However, people with a painful shoulder may need to avoid lying directly on that shoulder.

There is no universal rule requiring every healthy adult to change sides a specific number of times during the night.

Instead, pay attention to whether your current position helps you sleep comfortably and wake without persistent pain.

5. The Best Sleeping Position for People With Back Pain

Back pain is one of the most common reasons people begin questioning their sleeping habits.

Some wake up feeling stiff and sore, even after what appears to be a full night’s sleep.

In these situations, the goal is to find a position that reduces strain and supports the natural shape of the spine.

If you sleep on your back

Try placing a small pillow beneath your knees.

This can help reduce tension in the lower back for some people.

Choose a head pillow that supports the neck without forcing the head too far forward.

If you sleep on your side

Keep your knees slightly bent and consider placing a pillow between them.

Try to prevent the upper leg from crossing too far forward, as this may twist the pelvis and lower back.

If you sleep on your stomach

Consider experimenting with side or back sleeping if stomach sleeping seems to worsen your pain.

If you cannot comfortably change positions, a thin pillow beneath the lower abdomen may help some people reduce excessive arching in the lower back.

Persistent or worsening back pain should not automatically be blamed on sleeping posture. It may have other causes that require assessment.

Seek prompt medical attention if back pain occurs with new leg weakness, numbness around the groin, or loss of bladder or bowel control.

6. The Best Sleeping Position for People With Neck Pain

Neck pain may be influenced by the position of your head, the height of your pillow, and the way your shoulders rest against the mattress.

A pillow that is too high can push the head forward. One that is too low may allow the head to tilt toward the mattress.

Both can create an uncomfortable position for some people.

What can help?

If you sleep on your side, choose a pillow high enough to fill the gap between your shoulder and head without bending your neck upward.

If you sleep on your back, use a pillow that supports the natural curve of the neck while allowing the head to rest comfortably.

Avoid sleeping with your head sharply turned to one side for long periods.

You may also want to consider your daytime habits. Long periods spent looking down at a phone or leaning toward a computer can contribute to neck discomfort, which may become more noticeable at night.

If neck pain continues despite adjusting your sleep position and pillow, a healthcare professional can help identify the cause.

7. Sleeping Position During Pregnancy

Pregnancy changes the body’s shape, balance, and pressure distribution, which can make comfortable sleep more challenging.

Side sleeping is often recommended as pregnancy progresses, particularly during the second and third trimesters.

Sleeping on the side with the knees slightly bent may help reduce pressure on the back and improve comfort.

A pillow between the knees, beneath the abdomen, or behind the back may provide additional support.

However, recommendations about sleeping position depend on the stage of pregnancy.

As pregnancy advances, going to sleep on the back may place pressure on major blood vessels. Pregnant people should follow their obstetric clinician’s advice about safe sleep positioning, especially later in pregnancy.

If you wake up on your back, do not panic. Simply turn onto your side and settle back to sleep.

The goal is to establish a comfortable and appropriate position without creating unnecessary anxiety about normal movements during sleep.

8. Can Your Sleeping Position Improve Digestion?

Sleeping position can influence certain digestive symptoms, particularly acid reflux.

Acid reflux occurs when stomach contents flow backward into the esophagus, sometimes causing heartburn, irritation, or a sour taste in the mouth.

For people who experience symptoms at night, sleeping on the left side may reduce reflux compared with sleeping on the right side.

Keeping the upper body elevated may also help, especially when combined with other reflux-management strategies.

These may include avoiding large meals shortly before bedtime and identifying foods or drinks that consistently trigger symptoms.

However, claims that a particular sleeping position dramatically improves digestion, detoxifies the body, or accelerates metabolism are not well established.

A comfortable sleeping position can support rest, but it should not be treated as a cure for digestive disorders.

If you experience frequent heartburn, difficulty swallowing, persistent vomiting, or unexplained weight loss, seek medical advice.

9. Your Pillow May Matter as Much as Your Sleeping Position

Even a generally comfortable position can become problematic if your pillow does not provide adequate support.

A pillow that is too high, too low, or too soft may allow your head to tilt into an uncomfortable position.

The ideal pillow height depends partly on how you sleep and the width of your shoulders.

For side sleepers

A medium-to-higher pillow may be needed to fill the space between the head and the mattress, particularly for people with broader shoulders.

The goal is to keep the neck aligned rather than tilted toward the bed or ceiling.

For back sleepers

A lower or moderately supportive pillow may be more suitable, depending on its design and your body shape.

The pillow should support your head and neck without pushing your chin toward your chest.

For stomach sleepers

A thin pillow may reduce excessive neck rotation or extension. Some people prefer sleeping without a head pillow, provided this feels comfortable.

When should you replace your pillow?

Consider replacing a pillow if it has become flattened, lumpy, difficult to clean, or unable to provide consistent support.

There is no single replacement schedule that applies to every pillow. Material quality, use, care, and personal comfort all matter.

You also do not necessarily need the most expensive mattress or pillow available. A supportive product that fits your body and sleeping position may be more useful than one marketed with exaggerated health claims.

10. Is a Firm Mattress Always Better?

Many people assume that a hard mattress is automatically healthier for the spine.

But mattress firmness is not a universal measure of support.

A mattress that is too soft may allow some areas of the body to sink excessively. A mattress that is too firm may create uncomfortable pressure around the shoulders and hips, particularly for side sleepers.

The most appropriate mattress depends on your body shape, preferred position, comfort, and any underlying pain conditions.

If you wake up sore every morning, consider whether your mattress has developed uneven areas or no longer supports you comfortably.

Before buying a new mattress, you may want to test different firmness levels when possible.

Remember that mattress quality is only one factor. Persistent pain may have causes unrelated to your bed, and changing mattresses alone may not resolve it.

11. Why You May Still Feel Tired After Eight Hours of Sleep

Your sleeping position is only one part of healthy sleep.

You may sleep for eight hours and still feel exhausted if your sleep is frequently interrupted or if you have an untreated sleep disorder.

Other factors include:

• An irregular sleep schedule.
• Excessive caffeine late in the day.
• Alcohol close to bedtime.
• Stress and anxiety.
• Pain or uncomfortable room temperatures.
• Certain medications.
• Obstructive sleep apnea or other sleep disorders.

For most adults, regularly obtaining at least seven hours of sleep is a useful general target, although individual needs vary.

Try maintaining a consistent bedtime and wake-up time, keeping the bedroom dark and quiet, and allowing enough time for uninterrupted rest.

If you regularly wake up unrefreshed despite adequate sleep, particularly if you snore loudly or experience pauses in breathing, consider discussing this with a healthcare professional.

A change in sleeping position may help some symptoms, but it cannot replace appropriate evaluation and treatment for an underlying disorder.

12. Five Small Changes That May Help You Wake Up Feeling Better

You do not have to completely change your nighttime routine to improve sleep comfort.

Start with a few practical adjustments.

First, find a comfortable position. If you wake with neck or back discomfort, experiment with side or back sleeping and observe whether the change helps.

Second, adjust your pillow. Your head should not be pushed sharply upward, downward, or sideways.

Third, use pillows strategically. A pillow between the knees may help side sleepers, while one beneath the knees may help some back sleepers.

Fourth, create a consistent sleep schedule. Going to bed and waking at similar times can support your body’s internal clock.

Fifth, pay attention to recurring symptoms. Persistent pain, frequent nighttime reflux, loud snoring, or excessive daytime sleepiness may require more than a simple posture adjustment.

Make changes gradually. If a new position causes pain or makes breathing more difficult, stop forcing yourself to use it.

The purpose of changing your sleeping position is to improve comfort and support your health—not to follow a rigid rule.

Final Thoughts: The Best Sleeping Position Is the One That Meets Your Needs

So, which sleeping position is best for waking up refreshed?

For many adults, side sleeping offers a useful combination of comfort, spinal support, and potential benefits for snoring or nighttime acid reflux.

Back sleeping may be comfortable for people who want to reduce pressure on certain joints and support the natural curve of the spine.

Stomach sleeping can work for some individuals, but it often places additional strain on the neck and lower back.

None of these positions is universally superior.

Your age, medical conditions, pain patterns, breathing, pregnancy status, mattress, and pillow all influence what works best for you.

Rather than worrying about finding one perfect posture, focus on a position that allows you to breathe comfortably, minimizes pain, and helps you sleep consistently.

And remember: if you regularly wake up exhausted, experience persistent pain, or notice signs of a sleep disorder, do not assume that your sleeping position is the only explanation.

Sometimes, a better pillow or a small change in posture can make a meaningful difference. At other times, the most helpful step is identifying and treating an underlying medical condition.

A good night’s sleep is not about forcing your body into the “perfect” position. It is about giving your body the support, comfort, and rest it needs to help you feel your best the next day.
