Dear Doctors, I have recently starting breathing very heavily when I sleep. My husband says its heavy breathing through my nose and that it is not consistent. I am 25 with no medical history with regards to breathing. I don t smoke and I am not over weight. I gym 3 times a week, and eat relatively healthy. This has been happening for the last couple of months. When I wake up in the mornings, it feels like my nose is blocked and that I am not getting enough oxygen in. I have tried putting lavender oil on my pillow and many other things to open the airways. But my husband cant sleep at night.
