Hint: consider your sleep position.

Is your pillow to blame?

Sleeping with two pillows doesnt always mean two pillows under your head either.

Some like to place a pillow between their knees or under their legs for back or hip support.

To figure out this question, let’s go back to basics and consider spinal alignment.

Relaxation for your body and all its parts means quality Zs for you.

Sounds good, doesnt it?

Instead, heres how to narrow down your pillow needs.

You were able to get comfortable, your body was supported properly, and it could rest.

Then something magical happensyour body actually rests.

And because your body is resting, and not in distress, you stay asleep.

If youre not sleeping well on your current pillow(s), its time for a change.

Some people prefer soft pillows, others prefer more firm pillows, Dr. Shah says.

The difference is real, and it’s worth reconsidering.

Heres how to start.

Read the label to learn more about its design and purpose.

But if you opt for a soft, thin pillow, you may want to layer two together.

For example, side sleepers often prefer medium-firm pillows, Dr. Shah explains.

Stomach sleepers will probably want to go with a soft and thin pillow," Dr. Shah says.

So for stomach sleepers, one pillow is most likely enough.

Back sleepers have options, like placing a pillow under their knees.

So they may want a thin pillow under their head, and another propping up their knees.

Other physical needs or medical conditions also play a role in choosing yourideal pillow.
