The position that people adopt when sleeping It is not only related to the comfort: can also influence the heart health and in other aspects of well-being. Recent research on the effects of sleeping on your side, back and stomach reveals how these positions can affect diseases such as gastroesophageal reflux (GERD) or in the electrical activity of the heart.
Although there are no definitive conclusions yet, these findings offer new insights into the best way to sleep to promote optimal health.
Sleep from left side It appears to have some benefits for those suffering from GERD or acid reflux. A study 2022 showed that this position reduces exposure to acid and accelerates the cleansing of the esophagus compared to sleeping on the right side. By keeping the stomach below the esophagus, this position can help minimize reflux symptoms at night.
However, this same habit could have effects on the electrical activity of the heart. Research that began in 1997 and expanded in a 2018 study showed notable changes in readings of electrocardiogram (ECG) when people slept on their left side.
These studies observed that the position caused the heart to shift slightly, which affected electrical measurements, although it did not alter its actual function. With more advanced analysis using vectocardiographyresearchers found that the heart appeared to rotate and move, a phenomenon attributed to body position and not cardiac dysfunction.
Despite these findings, it is still unclear whether this position is harmful for those with heart conditions.
In contrast, sleeping on the right side offers a number of other benefits and can be a safe alternative for the heart. Some specialists suggest that this position could compress the vena cavawhich brings blood to the right side of the heart, although this has not been shown to significantly affect heart health.
And study of 2018 found that people with dilated cardiomyopathy They preferred sleeping on their right side, probably because it helps keep the heart in a stable position, which appears to reduce stress on the organ.
For pregnant women, choosing a side is also important. Although many doctors suggest sleeping on the left side to avoid pressure on the liver, the right side can improve circulation and relieve pressure on the liver. inferior vena cava. This can facilitate the return of blood to the heart, benefiting both mother and fetus.
For those who suffer heart failuresleeping position may be even more relevant. Sleeping on the right side is, in general, the most recommended option, especially because it tends to reduce the displacement of the heart and seems to minimize possible discomfort or changes in circulation.
In these cases, it is advisable to consult a doctor to obtain recommendations adapted to each specific condition. Some people with heart failure, especially those who also have sleep apnea, may benefit from sleeping on their back or with their torso elevated, either using a wedge pillow or in a reclining chair, which makes breathing easier during the night.
Despite the different recommendations regarding sleeping position, the evidence underlines that sleep quality It is crucial to maintaining a healthy heart. Sleep little or fragmented increases the risk of heart disease and other health problems, according to various studies in the area.
Therefore, beyond ideal posture, it is essential that people ensure they get a restful rest and consult a medical professional if they experience difficulty sleeping or symptoms of sleep apnea.
These recommendations and findings suggest that while sleeping position can influence different aspects of health, the key is to personalize it to individual needs and always prioritize good quality sleep.
