Do you wake up every morning feeling groggy?
Adenosine building up during the day is one thing that drives us to feel sleepy during the night. Then while you sleep, the adenosine is cleared out, leaving you refreshed and ready to go in the morning…for most people.
There is a genetic variant in the adenosine deaminase (ADA) gene that decreases the clearance rate of adenosine. People who carry the variant may get more slow-wave, deep sleep at night, but they also may need to sleep a little longer o feel refreshed the next morning.
- C/C: typical clearance of adenosine
- C/T: reduced clearance of adenosine, more deep sleep but may feel sleepy when waking up[ref]
- T/T: reduce clearance of adenosine, more deep sleep but may feel sleepy when waking up
