Inclined Bed Therapy (IBT) is a simple, non-invasive technique that modifies the sleep surface by raising the head end of the bed higher than the foot end. This adjustment uses the force of gravity to influence fluid dynamics within the body during rest. The fundamental principle is to create a gentle slope for the entire body, differentiating it from merely sleeping propped up on pillows. The effectiveness of the incline depends entirely on accurate measurement and proper physical setup.
The Standard Measurement for Inclining the Bed
The standard and most frequently recommended elevation range for Inclined Bed Therapy is a lift of approximately 6 to 8 inches at the head of the bed. This height is measured vertically from the floor to the base of the bed frame legs where the head of the bed rests. This specific lift translates to a subtle incline angle of about 5 to 8 degrees for a standard-length bed.
This gentle angle is deliberately chosen because it is high enough to induce a gravitational effect on body fluids without causing sleep disruption. A much steeper incline can cause a person to slide uncomfortably down the mattress throughout the night. This is why the measurement must be applied to the bed frame, not just the mattress, to ensure the entire sleep surface remains flat and supportive. Research has shown that a 6-to-9-inch elevation is effective in managing conditions like acid reflux.
The goal is to maintain a subtle, gradual slope from head to foot, which is distinct from the abrupt angle created by stacking pillows. This consistent, full-body incline is intended to align the spine naturally while allowing gravity to assist circulation and drainage. The 6-to-8-inch range balances therapeutic potential with comfort and stability for the average user.
Safe Methods for Bed Elevation
The physical implementation of Inclined Bed Therapy requires elevating the entire structure of the bed frame, not just placing an object on top of the mattress. Elevating only the mattress, such as with a large wedge pillow, can cause the body to bend at the hips, which can lead to spinal misalignment and neck strain. The correct approach ensures the sleeping surface remains flat, providing consistent support from head to foot.
One of the most effective and safest methods involves using commercially available, sturdy bed risers designed to fit securely under the legs of the bed frame. These risers are often made of plastic or wood and come in various fixed heights, allowing for a predictable and stable lift. Alternatively, solid wooden blocks, cut to the desired 6-to-8-inch height, can be placed under the bedposts. If the bed frame includes center support legs, those must also be supported to maintain the frame’s structural integrity.
It is important to ensure the risers or blocks are stable and feature a slight recess to prevent the bed legs from slipping off during the night. Unstable materials like stacked books, bricks, or small pieces of scrap wood should be avoided, as they pose a significant risk of collapse or shift. The structural integrity of the entire setup must be verified before use.
Important Safety Considerations
While Inclined Bed Therapy is a simple modification, individuals with certain pre-existing conditions should consult a healthcare provider before making the change. People with specific spinal issues, severe joint pain, or those at a higher risk of developing deep vein thrombosis (DVT) should seek medical advice. The slightly elevated position can sometimes mimic the effects of sitting, which may increase the risk of blood clots in vulnerable individuals.
Physical safety during the setup process is also a primary concern, demanding that the chosen elevation method is robust and incapable of sliding or collapsing. The risers or blocks must be securely placed under the bedposts. Non-slip pads under the foot of the bed can help keep the frame securely anchored, particularly on slick surfaces.
It is crucial that Inclined Bed Therapy is never used for infants. Inclined sleepers for babies have been associated with increased risks, as the elevated position can compress a child’s airway. For adults, if the incline is set too high or if the setup is unstable, it can lead to discomfort, back strain, or an increased fall risk when getting out of bed.
