Answer 2

Answer:

You may not have given much thought to your sleeping position, but the way you spend your night can have an impact on your overall health. Each position comes with its own pros and cons that you might want to consider next time you grab some shut-eye.

For example, sleeping face-up with a pillow under your back may help with back pain but may also worsen symptoms of sleep apnea. Sleeping on your side may be better for sleep apnea, but you may find that it hurts your spine.
