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.

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