The 4-7-8 breathing exercise

When you start blowing microphone will register you breath intensity level and will show it using the leds, as soon as you start blowing a count down to 4 is initiated and when you hear the "beep" sounds stop blowing. A count down to 7 will be initiated where you will inhale this time until you hear a "beep"sounds. As soon as you hear it exhale for a count down to 8 then you will hear a "beep" sound again. Do this set 4 times before going to bed

Note the more you practise this exercise the easier and the longer the effects will be.
