And, YES, the sleep study RTs put those masks on so tight, almost as if they are getting back at their spouses for an argument earlier in the day and are using your face to strangle the life out of them. They make them way too tight.
Yup, there is a trap in putting on most masks. If they are done up to what seems like normal tightness while standing up, the straps will strain when you lie down.
Most masks (I learned this particularly from the activa) don't need to be too tight when 1st placed on. If it is too loose when you lay down you can always get up & adjust a fraction tighter. Sooner or later you will get it right.
Also, I believe that a new mask too will require a bit of tightening over the 1st week.
The other *musts* with masks esp full face masks, is to wash your face (I use pure soap, not any with additives) before putting it on. As a man I used to shave as well but interestingly that didn't seem to offer the benefits I thought it should so I no longer bother.
PS also make sure you check the 'bridge' adjustment *after* lying down & not before - that can affect the pressure on your nose bridge.
Good luck
