The most common sleep position is on one's side and it's also the healthiest. Those who sleep in a side position have better spinal alignment, which can help with aches and pains all over the body. Furthermore, side sleeping opens up the airways and improves circulation in the sleeper's breathing passages. It can be beneficial for sleepers suffering from medical conditions caused by back sleeping, such as acid reflux and sleep apnea.
And we all know pillows are essential for a restful and healthy night's sleep. So, when selecting a pillow, always make the right decision.
