1, esophageal cancer: if you often sleep to the left, you are less likely to have stomach pain. In contrast, sleeping on the right side is easy to cause gastric acid to rush back to the esophagus. In serious cases, it will also lead to sore throat, cough, asthma, chest compression and other problems. In the long run, it will also lead to esophageal cancer. The researchers point out that this is because side sleep affects the position of the esophagus and stomach. When sleeping on the right side, the stomach is higher than the esophagus, and gastric acid easily flows back to the esophagus. It’s not easy to sleep on the left. In addition to esophageal cancer, many diseases are induced or aggravated by improper sleep posture. For people with certain diseases, it is necessary to pay attention to sleep posture.

2, heart disease: those with good cardiac compensation function can lie on the right side. If heart failure has occurred, half lying position can be used to reduce dyspnea. Do not lie on the left or prone.

4, lung diseases: for people with lung diseases on both sides, it is best to sleep on their back. If the left lung is ill, it is suitable to sleep on the left side; If the right lung is ill, you should sleep on the right side.

5, hypertension: patients with hypertension, especially elderly patients with hypertension, should sleep in semi recumbent position or lateral position. A large rectangular pillow with a height of 15 cm can be used to put their head and shoulders on the pillow.

6, cholelithiasis: , it is not suitable to lie on the left. Because the gallbladder is located in the upper abdomen, shaped like a small wine bottle. When the human body lies to the left, the mouth of the gallbladder bottle faces downward and the bottom of the bottle faces upward. In this way, gallstones are easy to fall into the neck of the bottle under the action of gravity, resulting in incarceration and the onset of biliary colic. Therefore, you should lie flat or sleep on the right side as far as possible.

7, low back pain: should sleep on your side, which can completely relax the muscles and avoid muscle tension, stimulation or compression of nerves, causing or aggravating low back pain.
