The power of Breathing:
Relax yourself

All breathing is done through the nose

Sit or lie comfortably
Close your eyes
Take a deep breath in (stomach rising)
Exhale slowly (stomach falling)

If you are unsure about the stomach breathing please read here first

Now, inhale for a count of 4
Pause for 1 count
Exhale for a count of 4
Pause for 1 count
Repeat 3 times
This is called equalising breathing- the inhalation and exhalation are the same length

Now, inhale for a count of 6
Pause for 1 count
Exhale for a count of 8
Pause for 1 count
Repeat 3 times

Now, inhale for a count of 8
Pause for 1 count
Exhale for a count of 10
Pause for 1 count
Repeat 3 times

Continue to breathe this way for as long as you want.
This is very good to do before falling asleep.

The most important thing to remember is to keep your inhalation 2 counts shorter than the exhalation. You may experiment and find that 10-12 and 12-14 also work well.
