This sleeping position should be avoided at all costs according to experts

Similar to the fetal position, but with the body relatively straight on one side, with the legs straight or knees slightly bent.
Benefits:
Reduces snoring and reduces sleep apnea (especially if the neck is supported by a suitable pillow).
Provides good support for the spine when the pillow is placed between the knees.
Suitable for pregnant women, especially on the left side, as mentioned in the fetal position.
Important Notes:
A flexible pillow should be chosen that supports the neck and vertebrae well to prevent excessive curvature.
The right-side position may slightly increase pressure on the gallbladder and liver; therefore, some studies recommend the left side as the most ideal.
❓ How to choose the optimal position for a restful and healthy sleep?
Use supportive pillows:
A pillow under the neck (located between the edge of the neck and the shoulder).
A pillow between the knees when sleeping on the side to maintain pelvic alignment.
A pillow under your stomach (if you must sleep on your stomach, try to reduce the curvature by placing a small pillow under your pelvis).
Gradual transition:
If you’re used to sleeping on your stomach, try sleeping on your side or back for a while at first until your body gets used to it, then gradually reduce the number of pillows you sleep on
Choose a suitable mattress:
Neither too soft nor too firm.
Medium firmness helps distribute your body weight and relieve pressure on your vertebrae.
Monitor sunlight and ventilation:
Make sure your room is well-ventilated and exposed to morning light, as the quality of the atmosphere helps stimulate the endocrine glands and regulate sleep hormones.
Avoid screens before bed:
Staring at your phone or TV before bed reduces sleep quality and affects your neck and back posture.
🔑 Summary and expert advice:
Avoid sleeping on your stomach completely; it is the most harmful to the spine and neck and can negatively impact your respiratory and digestive systems.
The best positions recommended by experts are sleeping on your back with a thin pillow under your knees, or lying on your side (especially on your left side) with a pillow between your knees.
Gradually changing your habit and ensuring you use supportive pillows and mattresses is an investment in your spine’s health and sleep quality.
Ultimately, the most important thing is listening to your body and how comfortable you feel when you wake up. If you wake up without pain or stiffness, this is a strong indication that your sleeping position is right for you.
Be sure to follow these guidelines to enjoy a restful and comfortable sleep and maintain the health of your back and neck in the long run. Your best friend on your journey to rest is your body itself: treat your body kindly, and it will treat you with comfort and peace of mind!
