Sleep is one of the most important parts of overall health. During sleep, the body repairs tissues, balances hormones, restores energy, and supports brain function. While many people focus on sleep duration, doctors say that sleeping position may also influence comfort, breathing, digestion, and circulation.
One topic that often surprises people is the effect of sleeping on the right side versus the left side. According to some medical experts, consistently sleeping on the right side may increase the likelihood of nighttime acid reflux in certain individuals.
The stomach naturally contains digestive acids that help break down food. When lying on the right side, the position of the stomach may allow acid to move more easily toward the esophagus. This may lead to heartburn, chest discomfort, sour taste in the mouth, or interrupted sleep during the night.
People who frequently experience acid reflux or gastroesophageal reflux disease (GERD) are often advised to try sleeping on their left side instead. Research suggests that the left-side sleeping position may help keep stomach acid lower than the esophagus, reducing irritation and discomfort.
