Dangers of Sleeping with Feet Elevated: Health Risks

The Dangers of Sleeping with Your Feet Elevated

Some people believe elevating the feet while sleeping can provide benefits like improved circulation or reduced back pain. However, consistently sleeping with your feet propped up higher than your heart can have negative effects on your health.

This article covers the potential dangers of making it a habit to sleep with your feet elevated. We’ll also look at when propping up the feet can be helpful and safe sleep positions to avoid health risks.

Why Do Some People Elevate Their Feet While Sleeping?

There are a few reasons why someone may choose to sleep with their feet propped up on pillows or raised on the mattress:

• Help relieve back or leg pain
• Reduce swelling in the feet/legs
• Improve circulation
• Aid in snoring or sleep apnea
• Personal comfort preference

While elevating the legs can provide temporary relief in some cases, making it an everyday sleep habit can lead to other issues. Let’s look at some of the risks.

Potential Dangers of Sleeping with Feet Elevated

Here are some of the most common problems associated with consistently sleeping with your feet significantly higher than your heart and head:

Disrupted Blood Flow

Sleeping with your feet raised above the level of your heart makes it more difficult for blood to be pumped uphill. This can lead to blood pooling in the legs rather than circulating normally.

Poor circulation during sleep places strain on the heart. It may cause symptoms like swelling, varicose veins, tingling, and painful legs/feet due to the blood supply being compromised.

Increased Pressure on Diaphragm

Having your legs inclined places upward pressure on your abdominal organs. This can push your diaphragm up, which compresses the lungs.

It can make it harder to fully inflate your lungs and get deep, restorative breaths while sleeping. This may worsen symptoms of respiratory disorders like sleep apnea.

Back and Neck Strain

Sleeping with your legs elevated often requires using pillows to prop them up. Having your legs tilted on pillows can rotate the pelvis and put strain on your lower back all night.

It also may cause your neck to bend or tilt in an abnormal position to accommodate the inclined legs. This can lead to pain, stiffness, pinched nerves, and poor sleep quality.

Tension Headaches

The changes in spinal alignment and neck position that occur when propping up the feet can also trigger frequent morning headaches.

The awkward neck and shoulder positions disrupt normal blood flow to the head. Chronic tension headaches are a common result of consistently sleeping with elevated legs.

Aggravated Swelling and Varicose Veins

While elevating the legs can help temporarily reduce swelling, it often makes swelling worse if done regularly at night. The impaired circulation and blood pooling in the legs increases fluid buildup and pressure in the veins.

It’s better to keep the legs relatively level with the heart while sleeping to allow proper blood return from the lower body.

Increased Fall Risk

Sleeping with your feet elevated on pillows or cushions makes it more likely to tumble out of bed if you roll over. This fall risk is greater in the elderly or small children.

Worsened Sleep Apnea

While mild elevation can help open airways for some with sleep apnea, having the legs and feet too vertical can worsen breathing pauses. This sleep position makes the diaphragm work harder.

Those with sleep apnea are safest sleeping on their side in a neutral horizontal position with supportive pillows.

Leg Nerve Impingement

Having your legs bent sharply at the knees for hours can increase pressure on the back of the knees. This may irritate the sciatic nerve or other leg nerves, causing numbness or shooting nerve pain.

When Is It Safe to Elevate Feet While Sleeping?

While routinely sleeping with your feet significantly elevated comes with risks, a small amount of inclination can be safe and helpful in some cases. Here are some instances when gently propping up the feet can be beneficial:

• Mild leg elevation after injury/surgery: Docs may recommend slightly propping up feet and legs to aid healing and reduce swelling after fractures, sprains, casts, or surgery involving the feet, ankles or legs.
• Pregnancy: Many women find resting with their legs gently elevated provides relief from swelling, varicose veins, and back pain during pregnancy. A small, wedge-shaped pillow under the ankles and calves can help take pressure off the legs and improve circulation.
• Minor foot, ankle or leg swelling: If you’ve been on your feet a lot and have temporary swelling, placing a pillow under your calves and feet while sleeping can help reduce fluid buildup.
• Congestive heart failure: Those with severe CHF may benefit from sleeping propped up on lots of pillows with legs slightly elevated to make breathing and blood flow easier.
• Respiratory issues: People with asthma, COPD or mild sleep apnea can try a small wedge pillow to open airways. But discuss with your doctor, as steep leg elevation can also worsen apnea.

In these instances, keep the head, neck and back in a neutral position without bending or tilting. Make sure the legs remain lower than the heart, with just a gentle incline that doesn’t cause strain or discomfort.

Better Sleep Positions to Reduce Health Risks

The best sleeping positions to minimize pressure on the neck, back and legs include:

On Your Back

Lying flat on your back allows your head, neck and spine to rest in a neutral alignment. Place a slim pillow under your knees if you have low back pain.

On Your Side

Sleeping on your left or right side with a slim pillow between your knees also maintains the natural curves of your neck and back.

Inclined Mattress

Adjustable beds that allow the head to be slightly elevated while keeping the legs relatively horizontal are a safer option. This reduces back and neck strain.

Pillows Under Calves

For temporary swelling relief, gently prop up just your calves and feet with a pillow, not bending your legs. Keep your head, neck and back flat.

When to Consult a Doctor

Talk to your physician if sleeping with legs elevated seems to help with certain conditions, such as:

• Circulation problems or chronic swelling in the lower limbs
• Restless legs syndrome
• Snoring or sleep apnea
• Shortness of breath or problems breathing at night
• Nighttime reflux or acid from the stomach
• Back or neck arthritis pain

Your doctor can help determine if gentle leg elevation is appropriate for your situation, and recommend wedge pillows and positions to reduce strain.

They can also diagnose and treat any underlying conditions, and provide other ways to manage swelling, breathing issues, reflux and pain safely.

Warning Signs to Stop Sleeping with Elevated Feet

Pay attention to your body for any of these signs that consistently sleeping with your feet raised is causing problems:

• Frequent headaches upon waking
• Increased lower back pain
• Worsening varicose veins
• Tingling or numbness in feet/legs
• Trouble breathing normally at night
• Fatigue and brain fog during the day
• Increased leg swelling
• Neck stiffness or shoulder pain

Discontinue elevating your feet and consult your doctor if you notice any negative effects on your health. They can help you find more optimal sleep positions.

When to Seek Emergency Care

See your doctor promptly or seek emergency care if sleeping with elevated feet results in:

• Sudden trouble breathing - This could signal a blood clot or fluid backup in the lungs.
• Rapid leg swelling - Fluid retention in the legs along with difficulty breathing can indicate a blood clot traveling to the lungs.
• One leg turning purple or blue - These are signs of a possible dangerous clot blocking blood flow.
• Severe chest pain - Angina or heart attack-like symptoms require emergency care.

While rare, sleeping with elevated legs can increase the risks of blood clots in those susceptible. Seek medical help if you have symptoms like leg swelling combined with sudden breathing problems or chest pain.

Tips for Safe Sleep Positions

Here are some general tips for practicing safe, healthy sleep postures:

• Use a medium-firm mattress that supports the natural curves of your neck, back and legs without sagging or bending.
• Support your head and neck evenly with a comfortable contoured pillow.
• Place a slim pillow between your knees or under them if you sleep on your side.
• Avoid using multiple pillows to prop up your legs, which strains the back.
• Consider an adjustable bed frame to allow gentle head and leg elevation adjustments.
• Don’t use lots of pillows to sleep propped up unless medically instructed.
• Talk to your doctor about positional therapy devices that improve sleep apnea without head, neck or leg strain.

Finding optimal sleep positions for your needs can prevent pain and health issues. Your doctor or physical therapist can recommend therapeutic pillows and props to support your best sleep posture.

Protect Your Health with Proper Sleep Hygiene

While elevating your legs during sleep may seem harmless, it can lead to circulatory problems, back and neck pain, headaches and other issues when done regularly.

Use gentle leg support if recommended by your doctor for certain conditions. But keep your head, neck and torso aligned and avoid straining your back.

Talk to your healthcare provider if you have health issues impacted by sleeping positions, and work to develop good sleep hygiene habits.

Pay attention to your body's signals, and discontinue any sleep posture that causes pain, breathing problems or other concerning symptoms. Practicing healthy, supported sleep is key to feeling your best each day.
