Best position for Sleeping:

Sleeping on your left side can help naturally open the airways and make breathing easier. You may also find relief if you rest on your right side, but doctors believe sleeping on your left side to be more effective. It's also the recommended sleeping position for people with sleep apnea.Sleeping on your left side is thought to have the most benefits to your overall health.

However there's some evidence that sleeping on your left side may shift your heart and disrupt your heart's electrical current. Also, many people with heart failure report having trouble breathing in left position.

Still, either side can offer benefits in terms of sleep apnea and chronic lower back pain relief. You don't have to stick with one side the entire night. Feel free to start on your left side and see how your body feels.Sleeping on your back may be one of the best positions for improving your sleeping posture.It promotes better alignment and reduces the pressure on your arms and legs. People with neck or back pain, especially in the lower back, find it to be the most comfortable.

Obstructive sleep apnea:
In adults, the most common cause of obstructive sleep apnea is excess weight and obesity, which is associated with the soft tissue of the mouth and throat. During sleep, when throat and tongue muscles are more relaxed, this soft tissue can cause the airway to become blocked.
The more severe the obstructive sleep apnea, the greater the risk of coronary artery disease, heart attacks, heart failure and strokes. Obstructive sleep apnea increases the risk of abnormal heart rhythms (arrhythmias), which can lower blood pressure.
