If you are struggling because of poor sleep there are a few measures you can immediately take.
In future posts I will explain why these measures should be immediately adopted.
As far as 6 and 7 are concerned these measures need to be properly taught by a breathing retrainer and you need to practise them as instructed. If you are a mouth breather, like I was, the respiratory settings in your brain need to be altered. And this takes time and significant adjustment.
Remember we breathe at least 20,000 times each day. So never underestimate the benefits which can flow from good breathing habits.
After your sleep study the use of a CPAP machine may be prescribed. That is fine as an interim measure – until you obtain some relief from quality sleep. But for me, and many others, CPAP may not be a long term solution.
