Sleeping on your side is actually pretty good for you. It can help to reduce snoring, aids digestion, and can even improve symptoms of heartburn.
Sleeping on your side is different from the fetal position because the knees are not tucked up. Interestingly, it’s especially good if you sleep on your left side. This study found that when people slept on their right side it significantly increased acid reflux and heartburn symptoms.
In certain cases, however, sleeping on your side is not always the best position. It can sometimes cause stiffness in the shoulders and jaw tightness.
Research also suggests that it can contribute to wrinkles, due to the skin being pressed up against the pillow for long periods of time. Plus, cotton pillowcases also cause friction against the skin which can lead to irritation and accentuate the appearance of wrinkles, lines, and creases. Silk pillowcases on the other hand, are great for your skin and hair.
If you like sleeping on your side, then it’s worth putting a pillow between your knees because this will help to align your hips better and avoid any onset of back pain.
It’s also important to sleep with a good pillow to avoid neck and back pain – and if you’re worried about wrinkles and creases, you might also like to invest in a silk pillowcase. You can read more about choosing the right pillow on the Healthline website.
