A way of breathing to relax

Now, I'd like to tell you how to breath to relax.

There are many methods of breathing, for example Zen breathing, Yoga breathing, Tai chi breathing or Karate breathing, etc.
Each of them have their own benefit and are worth to practice, however it takes time to improve those particular way.
So, let's try most easy way with me.

First, make sure if you are in safe place(trying in your room is better).
Stop where you are and stand still.
Close your eyes.
Inhale through your nose, deeply and slowly.
Then purse your lips and exhale through your mouth as deep and as slow as you inhaled.

Repeat inhaling and exhaling with same way until you feel calm.

...How was it?
The breathing makes your feeling better.
In addition, it has another effect.
When I have a stomachache, always I try this breathing.
Most of time the pain goes away.
Correct breathing can ease or erase your pain.

Try the breathing anytime if you need a break.
