Again.As the saying goes,you cannot make bricks without straw.Last time,I introduce two kinds of mattress.This time,I wanna teach you how to choose a nice pillow.To find a suitable pillow,we should check its height and hardness.
Height:
How tall a good pillow is? Well,the answer to this question is different from person to person.So,instead of height,what we truly care about is angle.A Japanese doctor found that if we want to sleep well,the angle of inclination of our heads is 15º.Like this.
Go find a pillow that can make the angle of inclination of your head become 15º.If you sleep this way,you can reduce the posibility of shoulder pain,backache,and headache.
Hardness:
Which is better,a soft pillow or a hard one?Though some people think the more softer the better,people shouldn't sleep on a pillow that is too soft.The reason is that a very soft pillow will prevent us from turning over.Can't turn over means that we don't change our postures frequently, and some parts of our body will be oppressed in a very long time. Then we will feel painful.
Yeah. I finish this article before midnight. Thanks for visiting my blog.

I like soft pillow:D
