I am wearing my G6 sensor on my right upper arm and am sleeping on my back or left side so there is no actual compression on the sensor. Four times last night I woke up on my left side to my low alarm with false compression lows. (This has also happened to me when my sensor was on my right leg while sleeping on my left side!) Has anyone else experienced this and, if so, how did you deal with it? I really need to get a good night’s sleep! Thanks!

Are you certain you didn’t just roll over when you woke up, and happened to be on the correct side? Liam has his in the same spot and has compression low once or twice per week. I have to go in and flip him over like a pancake. 
For him at least it’s very obvious when it’s a compression low as he goes from smooth and level to crash and burn in a single tick or two. I’ve never observed what appeared to be a compression low in him, that was not.

I don’t think so but suppose it is possible. I usually avoid sleeping on my right side because doing so causes shoulder pain, which I am not experiencing.

This hasn’t happened to me, but could it be due to less body fluid circulation, rather than compression? Are you less hydrated in warmer weather?

LOL, the is the first warm day (64 degrees!) we’ve had in weeks!
Seriously, adequate hydration is an excellent point. I think I am doing okay that way generally.
Today has been really weird with CGM readings 30-40 points higher than fingersticks. So I am beginning to think that this has something to do with sensor placement on my arm…

Or a bad sensor.
I generally get good results on outer arms.

I get compression lows on my Libre 2 even if I’m not lying on it. If I place the arm across my forehead when lying down, the tension that is created across the arm will cause it to alarm. Also if I’m typing on my computer and I’m tensing my arm, it will also cause the same reaction.

That’s a plausible explanation for why, whenever I have a sensor on my chest and I lie on my back, I get either a false compression low or a signal loss alert.
FUD, solving the mysteries of diabetes one by one.

Hope this can help…
Compression causes during sleep may include cover, tight clothes, animals, partner, pillows, or other body parts on the sensor.
Bluetooth info … Here are some things that can cause signal loss: other bluetooth devices disrupting signals, iPads, magnetic fields, bluetooth paging systems like what’s in a hospital, exercise machines, body parts, computers, ham radios, bluetooth splitters, walls, antennas broadcasting signals, software apps on the phone that control bluetooth signals or battery (Low Power Mode), kid’s bodies, animals, heating pad, heavy blankets…and more. My favorite is headsets that take up too much Bluetooth bandwidth.

@Beacher Yes. I put my sensor on my chest for the first time a couple of days ago and this was happening to me too. I finally got sick of it and put a new one on my arm.
LOL Cats seem to know exactly where a sensor is and settle down right on it!

@CatLady That’s for sure! Anytime I put on my thigh, my lap becomes target #1 for both of our cats! “It’s the rays!”
