Incline Sleep 101: The Benefits of Inclined Bed Therapy (Biohacking Your Sleep Part 9)

I've spent years studying this, working with sleep scientists, and testing it myself, and it comes down to a simple practice: Inclined Bed Therapy, or IBT. It's the practice of raising one’s bed 4 to 8 inches at the head by using blocks or wedges. With the head on a slight elevation from the feet, IBT allows for proper airway flow and helps with brain detoxification.  Sleeping on an incline is a simple way to improve your sleep quality and overall health. What I've seen in the research: an inclined sleep surface can reduce intracranial pressure, which can help reduce stress on the heart while sleeping. Incline sleep can offer a host of benefits, such as improved blood and oxygen circulation, relief from common ailments like acid reflux (GERD), heartburn, headaches, and snoring, and provide a deeper, more restorative sleep. 

From ancient Egypt to modern hospitals, inclined sleep surfaces have been used for centuries. In recent years, I've watched the benefits of sleeping on an incline come back into focus. From reducing acid reflux and snoring to improving circulation and reducing swelling, the advantages of sleeping on an inclined surface are becoming more widely recognized. 

Benefits of Sleeping On An Incline

Gravity for Better Flow

Our lymphatic system carries white blood cells throughout the body and helps to rid the body of unwanted materials and toxins. When you sleep on an inclined surface, gravity helps to facilitate the flow of lymphatic fluid, which can lead to improved overall health. It can also help improve the circulation in your body, which can help to provide more oxygen and nutrients to the body, which helps reduce inflammation and boost your immune system. 

Throughout the day, our hearts pump blood with solvents to our lungs. When our lungs exhale, it causes moisture to be released, creating denser fluid that descends to the kidneys. The kidneys filter the blood and remove solutes, which causes the blood to become less dense and rise back to the heart to be pumped again. And the cycle continues but gravity must be constantly acting on these fluids in order for the denser fluid to fall and the less-dense fluid to rise. This natural action reduces stress on the heart, lowering blood pressure, and relieving issues related to congestive heart failure, perfusion to the brain, varicose veins, and other conditions that involve pressure.

When you sleep on an inclined surface, your lungs can easily expire, allowing for better perfusion of the body. By sleeping in this position, gravity is allowing the body to have a more efficient circulatory system, with more oxygen and nutrients being transported to cells, allowing for quicker healing of the body’s organs and muscles. This allows for better quality sleep and improved overall health.

Brain Wellness

According to Dr. Tom Moorcroft D.O., approximately 90% of brain detoxification occurs while you're sleeping. Deep and slow wave sleep are deemed to be the most important phase of sleep. Anything that disrupts your normal sleep cycle has the ability to decrease your short and long-term brain health. Lack of quality sleep also leads to changes in the gut microbiome which may increase body-wide inflammation and can lead to further sleep disruptions.

Lots of biological things happen when you are asleep. Cerebrospinal fluid (CSF) is a fluid in your brain that flows and acts like a cleaner. It removes waste products and other harmful stuff you accumulated throughout the day. This process is called glymphatic drainage. It has been reported that sleeping on a flat surface can increase intracranial pressure and cause sinus, ear/eye/face pain and in some cases migraines have been triggered if you spend too much time lying flat.  CSF should be flowing freely and not act like a stagnant lake. Sleeping on an incline, even as little as 5%, allows CSF to flow and cleanse the brain.

Scientists and physicians long debated why we sleep. Today we know sleep is required for better long-term memory, improved learning, repairing tissue and muscle and better mental and physical health.

Sleep Position

When sleeping on an incline, no matter which position we sleep in, gravity is positively acting upon the digestive system by helping to move food more quickly through our intestines, which helps prevent heartburn, acid reflux, constipation and diarrhea. It is believed that sleeping on your side (lateral) position compared to sleeping on your back or stomach is more effective and promotes better digestion. When you’re feeling bloated or gassy, it’s the natural side effect of digesting food. But when that food moves through your system too slowly, the gas doesn’t have a place to go and you wind up feeling bloated. Sleeping on your left side lets gravity help waste get from the small intestine to the large intestine and travel more freely to reduce the potential of digestive difficulties.

When we lie down, our hearts require less energy to pump against the power of gravity, thus resulting in blood flowing more quickly and powerfully into the head and neck. In the same breath, without gravity to help the brain to send blood back down towards the heart, your blood tends to pool in the veins in our head. The result is increasing pressure and not allowing new blood from entering the brain with its much needed oxygen and nutrients. 

Gravity affects our feet and ankles in a similar way to our brains. During the day, fluid is drawn to our lower extremities by the pull of gravity but this stops at night when we lie flat. Our hearts don’t usually have to work very hard to get blood to our feet since gravity does much of the work for us. When we are lying down, it is harder for our hearts to maintain effective circulation in our legs. 

Zero Gravity

Similar to those fancy lawn chairs, zero-gravity adjustable bed bases support your body while you sleep in a neutral position with your upper and lower body perfectly balanced. While your head is lifted to sit above your heart, your legs are bent at the knee so that your thighs and torso are evenly angled from your hips. The result is a weightless feeling that can provide a more comfortable way to sleep for some. It can also help with snoring, acid reflux, and general aches and pains. 

These beds are a good investment for people who suffer from allergies, obstructive sleep apnea, or snoring since they let you sleep at an angle and can facilitate better breathing. Since adjustable beds help ease joint and muscle tension, this makes them an excellent purchase for older individuals with chronic or acute pain as well as very active individuals and athletes. Additionally, these beds promote blood flow and oxygen intake, which is particularly important for bedridden seniors. 

Laying on a flat surface can place strain on your neck, lower back, and hips. It can also partially obstruct your airways. Sleeping at an incline aligns your neck, spine, and hips, relieving strain. This position also clears your airways by keeping the soft tissues around the back of your throat from partially blocking the windpipe.

Incline Sleep, Concussions, and Brain Recovery

A study published in The BMJ in August 2026 gave the sports world one of its clearest pictures yet of how common chronic traumatic encephalopathy (CTE) is among former NFL players. Researchers from Mass General Brigham and Boston University's UNITE Brain Bank reviewed brain donations and death records for players who died between 2016 and 2021, and found that at least 25% had CTE, a figure the study's lead author, Dr. Daniel Daneshvar, called a conservative, "low end" estimate. Within the smaller pool of donated brains specifically analyzed at the UNITE Brain Bank, 93% showed signs of the disease. (NPR, citing The BMJ)

CTE itself can currently only be diagnosed after death, and there is no cure. But the study has renewed a broader, more immediate conversation: how do we support the brain's recovery in the days, weeks, and months after a concussion, while an athlete is still living?

For Essentia founder Jack Dell'Accio, that conversation isn't new. He's spent more than 15 years working with athletes, including partnerships with NFL teams, on recovery protocols for active players. His approach consistently comes back to one practice: inclined sleep.

"Every time there's a concussion I'm dealing with, I go to a protocol of inclined sleep," Jack explains. "Inclined sleep basically eliminates that cranial pressure, promotes lymphatic drainage, and is really helpful in that rest and recovery for accelerated recovery from concussions." For years, that meant custom-rigging a player's bed to achieve the right angle. Today, it's built into the Align X Adjustable Base, which automatically adjusts to the incline level needed, no rigging required.

How to Sleep on an Incline: The Align X Adjustable Base

There are two ways to practice Inclined Bed Therapy. The traditional route is to raise the head of your existing bed frame 4 to 8 inches using blocks or wedges, the same DIY method IBT practitioners have used for years. It works, but it's a fixed angle, and it can mean an uneven, sometimes uncomfortable sleep surface.

The easier route is the Align X Adjustable Base with Incline. Unlike most adjustable bases, which treat incline as an afterthought to their recline function, Align X was built around true incline sleep from the ground up. It offers up to 7 degrees of full-bed tilt and 7 inches of height adjustment, so the entire mattress surface, not just a propped pillow or a bent mattress, tilts to elevate the head. Jack's team made incline positioning a standard feature on Align X so that everyone, not just athletes managing concussion recovery, can sleep healthier at an angle.

Because the incline is engineered into the base itself, you get the benefits of elevation without feeling like you're sleeping on a slope.

Incline Sleep FAQ

What is Inclined Bed Therapy (IBT)?

Inclined Bed Therapy is the practice of sleeping with the head of the bed raised, traditionally 4 to 8 inches, to allow gravity to assist circulation, lymphatic drainage, and airway flow.

How do I sleep on an incline?

You can raise the head of your bed frame with blocks or wedges, or use an adjustable base like Align X that tilts the entire mattress surface to your desired angle with the push of a button.

Is sleeping on an incline good for you?

For most adults, yes. Research points to benefits for circulation, lymphatic and glymphatic drainage, acid reflux, snoring, and general comfort. It is not recommended for babies, who should always sleep on a flat, firm surface.

How many inches should I elevate my bed for incline sleep?

Traditional IBT guidance is 4 to 8 inches at the head. Adjustable bases like Align X let you fine-tune the exact angle rather than committing to a single fixed height.
