Elevated Head of Bed

Reducing acid reflux and sleep apnea symptoms

Evidence · Grade BSafety · Generally safe
Traditional use

Elevating the head of the bed is a non-pharmacological intervention that uses gravity to reduce symptoms of conditions like acid reflux and sleep apnea by preventing upward flow of stomach contents or improving airway patency.

Last reviewed June 17, 2026 · AI-assisted, human-reviewed
Elevating the head of the bed (EHB) involves raising the head of a person's bed by several inches, typically using blocks under the bedposts or a wedge pillow. This simple physical maneuver aims to use gravity to alleviate symptoms associated with certain medical conditions, particularly those affected by supine (lying flat) positioning. The degree of elevation can vary, but common recommendations range from 6 to 8 inches (15-20 cm).

Evidence Summary

Evidence · Grade B

There is consistent evidence from multiple studies, including randomized controlled trials and systematic reviews, supporting the efficacy of elevated head of bed for reducing symptoms of Acid Reflux (GERD) and improving outcomes in Sleep Apnea. The mechanism is well-understood, relying on gravity. While not a cure, it is a widely recommended and effective adjunctive therapy.

Why It Works

EHB primarily works by leveraging gravity. For acid reflux, it helps keep stomach acid down, reducing reflux into the esophagus. For sleep apnea, it may help maintain an open airway by preventing the tongue and soft tissues from collapsing backward.

How it works in more detail

In the context of Acid Reflux (GERD), elevating the head of the bed helps to reduce the frequency and duration of acid reflux episodes by preventing gastric contents from flowing back into the esophagus. This is achieved by increasing the angle between the esophagus and the stomach, making it more difficult for stomach acid to overcome gravity. For Sleep Apnea, EHB may improve upper airway patency by reducing rostral fluid shift (movement of fluid from the legs to the neck during sleep) and by altering the gravitational forces on the pharyngeal tissues, potentially reducing airway collapse. It can also help with post-nasal drip and sinus drainage.

How to use

Always consult a qualified clinician.

Editorial guidance

Suggested dosage
Elevating the head of the bed by 6-8 inches (15-20 cm) using bed risers or a wedge pillow placed under the mattress.
Research dosage range
Typically 6-8 inches (15-20 cm) of elevation at the head of the bed.
Typical onset
Immediate upon elevation.
Quality markers
Ensure the elevation is stable and comfortable, and that the entire torso is elevated, not just the head, to avoid neck strain.
Avoid if
  • Unstable bed frame
  • Significant discomfort or pain
Pregnancy / lactation
Generally considered safe during pregnancy and lactation. May offer relief for reflux symptoms common in pregnancy.

Active medicinal compounds

Not applicable (physical intervention)

Traditional use

The concept of elevating the head during sleep for comfort or to alleviate breathing difficulties has likely been practiced informally for centuries. Formal medical recommendations for conditions like GERD and sleep apnea are more recent.

Safety

Safety warnings

Ensure stable elevation to prevent the bed from shifting or collapsing. Avoid elevating only the head with multiple pillows, as this can cause neck strain and may not be effective for reflux. Some individuals may find it uncomfortable or experience back pain; adjust elevation as needed.

Avoid if

  • Unstable bed frame
  • Significant discomfort or pain

Reported side effects

  • Neck pain (if only head is elevated)
  • Back discomfort
  • Difficulty sleeping in an inclined position
  • Bed instability

Pregnancy & lactation

Generally considered safe during pregnancy and lactation. May offer relief for reflux symptoms common in pregnancy.
