A Sleep Psychiatrist On The Impact Of "Arm Sleeping" & What To Do Instead

Another common culprit for neck and shoulder pain? Sleeping on your arm. Here, Nishi Bhopal, M.D., a psychiatrist specializing in sleep medicine, explains to mbg why sleeping on your arm can cause problems, and what to do about it.

In particular, Bhopal notes those with a history of shoulder injuries or nerve impingement should definitely avoid sleeping with their arm under their head, especially on the side of the injury. 

Propping your head and pillow up on your arm is an indication your pillow isn't supportive enough, whether it be too flat or just not firm enough. When we sleep on our sides, our pillow needs to completely fill the space between our head and shoulder, to keep everything in alignment. "Use a pillow that will support your neck and keep your head aligned with the spine," Bhopal adds.

If you can, it might be worth trying to sleep in another position, such as on your back, especially if you're waking up with any pain, Bhopal says. This could even mean switching sides if you tend to prefer one side when you sleep.

Along with making sure the pillow under your head is supportive enough, you can also work with some strategic pillow placement to further support alignment. When on your side, "you can put a pillow between the knees to keep your hips aligned," Bhopal says, "and hug a pillow in front of you to reduce the pressure on your shoulders."

To offset some of the effects of arm sleeping, Bhopal says light shoulder rolls and neck stretches can help loosen things up. Just be sure to warm up first if you're looking to stretch first thing in the morning. Our bodies are typically the most stiff when we first wake up, so Bhopal says it's best to loosen up with a warm shower or some light exercise.

And lastly, to go the extra mile and ensure you wake up feeling your best, don't let basic sleep hygiene fall by the wayside. Taking a sleep-supporting supplement like mbg's sleep support+, setting the thermostat to the optimal sleep temp of 65 degrees, having regular sleep and wake times, and encouraging overall well-being through a healthy diet and exercise all contribute to a better night's sleep (and morning).*

If you sleep on your arm, it could be negatively affecting your neck, shoulders, and general sleep quality—but with a little adjusting and a sufficiently supportive pillow, you can get comfy without your arm under your pillow, and your neck will thank you for it.
