4. It’s ideal for pregnant women.
Sleeping on the left side doesn’t only improve pregnant women’s circulation. It can also help to relieve pressure on the back, keep the uterus from squeezing the liver, and increase blood flow to the uterus, kidneys, and fetus. For this reason, doctors tend to recommend that pregnant women spend as much of their sleep time as possible on their left sides.
5. It may reduce heartburn.
A study published in The Journal of Clinical Gastroenterology found that lying on the left side can help reduce acid reflux symptoms. Again this is because our stomach lies on the left side. Conversely, lying on the right side may aggravate these symptoms. The effects are fairly immediate; if you’re struggling with heartburn after a meal, try taking a 10-minute lie-down on your left side.
6. It may relieve back pain.
People who suffer from chronic back pain may benefit from switching to left-side sleeping. That’s because sleeping on your side can relieve pressure on the spine. Feeling more comfortable, in turn, will improve your chances of getting a good night’s sleep.
While all of these factors point to compelling reasons to start sleeping on your left side, it’s important to note that some people—including those with heart disease, sleep apnea, glaucoma, and carpal tunnel syndrome—may not benefit from side sleeping. If you’re unsure about what sleep positions may be best for you, it’s always a good idea to consult a medical professional.
How to make the switch
If you are ready to make the switch, you’ll find that it may take some time to build the new habit of sleeping on your left side. Implementing a few simple strategies can help ensure a smooth transition. For instance, you may want to experiment with putting a body pillow behind your back so that it’s harder for you to roll off of your left side during sleep. It can also be helpful to try sleeping on the opposite side of the bed than you normally do; that way your sleep orientation won’t feel much different (even if you’re sleeping on your opposite side).
It will also be important to choose a mattress that’s ideal for side sleeping. Because sleeping on your side can put pressure on the hips and shoulders, it’s important to choose a softer mattress that will help relieve pressure in those areas. Also be sure to look for a mattress that allows the spine to rest in natural alignment. And of course, make sure that whatever mattress you choose feels comfortable to you. The combination of a comfy bed and a health-promoting sleeping position is sure to increase your chances of sleeping well and feeling great whenever you wake up.
