Did you know that the posture in which you sleep influences many aspects of your body and your anatomy? Discover the reasons why it is better to always lie on the left side. If you are one of those people for whom sleeping every night is a real ordeal, you will surely be interested to know that the posture in which you lie can influence you to get it sooner or later. According to various studies, when you sleep reclining on the left side of your body you conciliate much earlier and better sleep than if you do it in any other position. Also, it is also proven that sleeping on this side makes the quality of sleep better and that you get up much more rested.
Sleeping on your side is one of the favorite positions of many people. Some prefer the right side and others sleep on the left side. But according to scientific studies, the latter is the most beneficial to health. Most people have some sleeping positions they prefer, and these are the ones they use every night to rest. However, there are studies that suggest that sleeping on the left side is beneficial for health.
- Improves the function of the glymphatic system:
Sleeping on the left side favors the function of the glymphatic system since brain waste is better eliminated. This decreases the risk of developing neurological diseases such as Parkinson’s and Alzheimer’s. Many types of dementia are linked to sleep disorders, including difficulty in reconciling it. It seems increasingly clear that these problems can accelerate memory loss in Alzheimer’s disease. Our findings provide new knowledge on the subject, showing how important the position in which you sleep is.
- Improves the lymphatic system:
The spleen is located on the left side and is essential to filter the blood and perform a correct function of the lymphatic system. When sleeping on the side, the fluids reach the spleen by the natural force of gravity, thus favoring its task. The lymph drains mostly to the left side.
- Improves stomach acidity:
The pancreas and stomach are on the left side of the body. Therefore, if this position is adapted to rest, digestion is favored, since gastric juices are better channeled and pancreatic enzymes are secreted more easily. Also when you have stomach acid or reflux is the very important to the position that is adapted to sleep. Although the one that the doctors usually recommend is with the head raised a little above the shoulders so that the stomach acid does not rise, sleeping on the left side also has its benefits. There is scientific evidence to show that sleeping on the right side worsens the acidity at night because the lower esophageal sphincter relaxes favoring the transit of gastric acid.
Beneficial for the heart:
80% of the heart is located on the left side when sleeping on that side; the drained lymph is driven by the force of gravity, thus reducing its work during sleep. It also pumps blood more easily. In pregnancy, women are usually recommended, as far as possible, to sleep on the left side to avoid putting pressure on the vena cava, the largest vein in the body, which carries a large amount of blood to the heart and placenta.
This recommendation is complemented by the findings of scientists who suggest that sleeping on the right side in the last weeks of pregnancy could be associated with a higher risk of fetal death. This novel discovery is directly related to the pressure exerted when sleeping on that side on the vena cava. Since the flow of blood and oxygen that reaches the baby is reduced.
