It's important to recognise some of the common symptoms and understand why you may be feeling so tired and find out what to do if you do have sleep apnea.

     If you’ve tried improving your sleep, but still snore or wake up feeling tired, you may be at risk of a common sleep disorder called sleep apnea.

       "Apnea" literally means "no breath" or "stopping breathing".

     Sensing you have stopped breathing, a control centre in your brain triggers you to wake up just enough to gasp and start breathing again. Then you fall back to sleep and the cycle begins again—this can happen more than 50 times every hour, even though you may not remember waking up.

      When you have an apnoea, air stops flowing to your lungs for 10 seconds or longer—that is, you actually stop breathing.
