This is also the position you take.
Every night, about the population sleeps in the same location, where experts reveal the health pros and cons of your favorite posture.
Known as the recovery position, because it is similar to the posture used in medical emergencies, which can help reduce acid reflux and help with indigestion, experts say, professor Jim Horn of the sleep research center at Loughborough University said.
These conditions are collectively called the stomach.
Esophageal reflux disease occurs when stomach acid splashes into the esophagus (
Pipe that transports food from the mouth to the stomach).
This leaking acid is caused by weakness at the junction of the stomach and esophagus and causes burning pain.
The key is to sleep on your left.
In the Philadelphia graduate school study of heart-burning patients, doctors found that sleeping on the right means that the leaked stomach acid is discharged from the esophagus for longer than sleeping on the left, so people sleeping on the right are more uncomfortable.
Medical staff are unsure of the reasons behind this impact.
But while it can relieve pain in the stomach, sleeping sideways can aggravate wrinkles.
Dr. Dennis Wolfe, a member of the British Association of Cosmetic Dermatologists, explained that this increased the pressure on the nasolabial groove from the corner of the nose to the side of the mouth
Called the line of laughter.
Depending on the side you usually sleep on, the laughter on this side of the face can be deeper and more obvious, which is the result of the face being pressed onto the pillow.
Action: If sleeping on the left side does not help, heartburn and indigestion are still a problem, please support your bed slightly, so the upper body is higher than the stomach.
This helps reduce acid reflux during sleep, as gravity keeps acid in the stomach.
According to Dr. Wolf, there is some discussion that silk pillows can help reduce wrinkles caused by stress during sleep because silk is softer than other materials.
This has not yet been confirmed, however.
Good for: Arthritis: asthma, snoring, sleep apnoea, heart health experts say: for those with arthritis and joint pain, sleeping in the back is a good choice, says Sammy Margo, a licensed physical therapist and author of The Good Sleep Guide.
This is because sleeping on your back will distribute the weight evenly throughout the body without causing stress to any specific area.
However, it is well known that the same sleeping posture can aggravate snoring.
In this position, the muscles of the chin and tongue relax and, under the influence of gravity, the chin and throat sag.
This causes a narrow throat, creates airflow, causes shock and snoring, says Dr. John Shelson, director of Sleep Center at Papworth Hospital, Cambridge.
This is especially true for overweight adults, and the weight of excess fat in front of the neck can exaggerate the degree of throat sagging.
Sleep apnoea is a more serious disease with a complete closure of the throat, causing intermittent pause of breathing for 10 seconds or more.
Similarly, due to the effect of gravity on the throat, sleeping on the back can aggravate this situation.
\"Research has shown that people who sleep on their backs are more likely to reduce oxygen levels in the blood, which is a particularly worrying problem in patients with heart and lung disease, dr. David ekleston, Birmingham general practitioner who specializes in sleep problems, said.
People who sleep on their backs breathe faster than any other place where they sleep, so the tissue of the body becomes deficient.
This may exacerbate some breathing and circulation problems, including asthma and heart disease.
Action: If this is your favorite sleeping pose, then make sure you invest in a solid pillow, says Dominic Chesham, a chiropractor from London.
Lack of support for the neck and upper spine can cause tension in the neck and shoulder muscles, resulting in pain.
Dr. Shneerson said that for those who only snore when they sleep up, placing a pillow under their upper back might encourage them to change where they sleep and
Benefits: lower back pain: neck pain, head pain expert said: this is the most common sleep posture in the UK, three of us sleep by our side and our legs stretch to the chest.
Sleeping like this can help repair the wear of the back.
\"Throughout the day, the spine is subjected to gravity, which puts a lot of pressure on the disc --
Sammy Margo says the cushion between the bones in the back.
During sleep, when the back is not compressed, the water in the body is attracted to the disc, which helps to repair the wear.
She suggests that it is ideal to sleep in the position of the fetus, as curling the body inward will open the back, reduce the pressure on the disc and promote repair.
However, she also stressed that it is important to ensure that the neck is consistent with the rest of the body.
In other words, make sure your pillow is not too high or too low, as it can strain the muscles and nerves of the neck and cause pain in the head and neck in the morning.
If you experience lower back pain, make sure the neck and spine are straight, and there is no distortion in the hips and abdomen, which can aggravate the condition, she said.
Neck strain can also lead to tension headaches.
According to Dr. Farhad Afshar, a consultant neurosurgeon at the London Clinic, the cervical spine tension located at the bottom of the skull can cause pain to radiate to the back and overhead, giving a feeling of constant stress.
Action: find a pillow that can properly fill the gap between the shoulder and neck and help prevent neck strain or headache.
Lay your partner in this position and look at their spine and neck
They should be straight.
Sami Margo says pillows that support between the knees can help keep the spine aligned and prevent unnecessary distortion of the hips and pelvis.
Experts say: Lying in each other\'s arms will definitely enhance the intensity of a relationship, and a study conducted by American neuroscientist and psychologist Dr. James Cohen found that physical contact, even when sleeping, it can also reduce the pressure on men and women.
However, this position may mean that you force your body into a position that can aggravate existing pain and tension in joints and muscles.
Sammy Margo suggests that it is important to remember that your body will change over time and that the posture that used to be comfortable may no longer be the case.
\"Lie by your side and your partner sleeps near your body, either in front of you or in the back --
Often called spooning-
It can cause back and shoulder pain, while sleeping on your partner\'s arm or chest can cause your neck to be out of alignment with your spine, causing neck pain.
Action: when in bed with a partner, it is important to be selfish about your sleep arrangements.
Sammy Margo said, find a good starting position that is comfortable for you, even if it means keeping the distance between you two.
Dominic Chesham said that because people of different weight and body sizes need different types of mattresses, couples may also have different mattress preferences and needs.
This can be solved by buying two different mattresses (
Strong and soft, for example)
It can then be compressed together.
OK: bad snoring: tooth grinding, hand pain, hand numbness expert said: sleeping in front helps prevent snoring, Dr. shneerson said, because the muscles in the throat do not drooping backwards under the action of gravity.
However, it will make the situation worse if you are a dental grinder.
According to Dr. Mani Bhardwaj, a dentist at smile Studios in London, when people sleep in front, their lower jaw is farther than normally.
This means that if people do bite their teeth, there will be extra pressure on the lower teeth, resulting in serious wear and tear.
This position can also cause nerve problems in the upper body.
\"When lying in front, too many or too little pillows affect the position of the neck to make it out of alignment with the spine.
This will increase the likelihood of nerve compression, especially in the elderly, Dr. ecreston said.
Also, you have to rotate your neck to the left or right, which creates pressure on one side.
When the bones of the spine compress the nerves of the neck, the nerves are oppressed.
As the age grows, the risk of this condition increases as the spine becomes arthritis, as this narrows the channel through which the nerves must pass.
People with the disease often complain about numbness and tingling.
Action: Dr. ecreston recommends latex foam or pockets-
Spring mattresses, because these mattresses will be formed according to the shape of your body, better support and protect your spine than ordinary spring mattresses.
Sammy Margo said: \"You can also try to sleep on a pillow that is placed vertically under your belly and on your shoulders as it helps to reduce the arch of your back.
