Sleep position is a perennial topic that you’ll see often talked about in the media. In most cases, your sleep position is thought to predict your personality type. However, there’s a simpler explanation for why you may prefer to sleep on your side or on your tummy. This has to do with the shape of your face, and in particular, the size of your upper airway.
About once every few months, I’ll see a woman who complains of 4 weeks of frequent sinus infections, facial pain and misery. She was given multiple courses of antibiotics and allergy medications, all with only temporary relief. When I examine her upper airway, it’s usually very narrow, especially when she’s lying flat on her back. I ask her about her sleep position, and she’ll state that she likes to sleep on her back. I don’t believe her. Then I ask her what her favorite sleep position was 3 years ago. She replies that she used to sleep on her stomach. When did she change? About 4 to 5 weeks ago. Why did she change? Her dermatologist told her that she’ll get wrinkles on her face if she sleeps on her stomach.
Not unexpectedly, after switching back to her tummy during sleep, her sinus problems get better. In addition, I make sure that she stop eating close to bedtime and that her nasal breathing is optimized. What’s happening is that on her back, her tongue falls back more due to gravity, and during deep sleep, with total muscle relaxation, she stops breathing and keeps waking up. Poor sleep quality over time will cause sinus migraines, and even more facial wrinkles.
In the video below, I talk about how your facial shape can predict your sleep position.
If you’ve had to change your sleep position for whatever reason, why did you do so, and did it affect your sleep quality?
