What is your preferred sleeping position? You’re probably more accustomed to sleeping in a particular position, or maybe you start off in one position and wake up in a different one. Are you interested in knowing what science has to say about the various sleeping positions? Well, we’re here to share the insights.
First and foremost, it’s important to note that the position you sleep in does have an impact. Scientists have conducted numerous studies aiming to find conclusive answers. And they have indeed made a significant discovery: the preferred side for individuals who sleep in this manner.
The best way to sleep
Despite the existence of numerous studies with conflicting findings, scientists generally agree on one clear conclusion: sleeping on your back is the optimal choice.

Sleeping on your back offers several advantages. It helps maintain better alignment of your spine, reducing the risk of long-term issues. Additionally, this position can be beneficial in alleviating headaches and chest pains by avoiding unnecessary pressure in those areas of the body. Moreover, although it may not be widely discussed, sleeping on your back also benefits your facial health. It is considered one of the best techniques to minimize the appearance of wrinkles and potential skin irritations.
The best side to sleep
The question of whether it’s better to sleep leaning on the left side or the right side is indeed important, considering that not everyone sleeps on their back. Sleeping on your back voluntarily can be challenging for many individuals, and it can become even more complicated when you’re hospitalized and restricted to that position by doctors. It’s not always comfortable, and the inability to change positions adds to the difficulty.

That’s why, in everyday life, when you simply want to rest without any additional concerns, you tend to sleep leaning on one side. Now, if one side is better than the other, it would be interesting to know. The good news is that scientists have extensively studied this matter and have found clear evidence that sleeping on the left side is the most advantageous. What’s even more surprising is that there is growing support within the community for the idea of sleeping on your side instead of on your back. Who knows, with further discoveries about its benefits, it might even become a trend in the coming years.
But why specifically the left side? One reason is the positive impact it has on digestion, as the stomach is located on that side. According to a study published in the Journal of Neuroscience, sleeping on the left side promotes easier movement of waste through the intestines, thereby enhancing the body’s natural digestive process and resulting in a better overall feeling. Additionally, sleeping on the left side helps minimize stomach pain caused by various factors, including inflammation, as indicated by a study conducted by the National Center for Biotechnology Information (NCBI) in the United States. Another benefit of sleeping on the left side is its positive effect on reducing gastric reflux, as stated by a study. In contrast, sleeping on the right side has been found to have the opposite effect, potentially exacerbating reflux issues. Lastly, sleeping on the left side also improves blood circulation, which is an important additional advantage to consider.
Benefits on both sides
In any case, experts suggest that there is no need to be overly concerned if you prefer to sleep leaning on the right side. As mentioned earlier, it is quite common to start off sleeping on one side and eventually switch to the other.

Side sleeping, regardless of the side, offers its own set of benefits. One notable advantage is the potential reduction in snoring. This is particularly relevant if you share a bed with someone who snores or have experienced it with your parents. Moreover, sleeping on your side has been found to alleviate lower back and joint pain. While there is a possibility of experiencing shoulder pain, this largely depends on your body structure and how you position that area. If you typically don’t experience shoulder discomfort, you may not notice any issues. However, if shoulder problems are frequent for you, it might be more suitable to continue sleeping on your back. Additionally, side sleeping has been shown to be beneficial for individuals with sleep apnea, which is an important factor to consider.
In general, considering the pros and cons, it is plausible that sleeping on the left side will continue to gain support from the scientific community in the future.
