I fall asleep fine, but my Samsung smart watch indicates I get very little deep sleep which is what your body needs to recover.
Still trying to get to the bottom of that, we have recently changed our entire bed/mattress (we were moving house) and I also got a Simba Hybrid pillow that you can adjust yourself by taking out or putting in more foam cubes.
My sleep score is still often only around the 40-60 range though.
I'm not sure those watches are that accurate in assessing sleep quality, I can't remember which program it was I was watching but they compared it against a proper sleep study and the differences were vast.
