Has anybody experienced super noisy readings when showering? I use xDrip+ on my Android phone with a Dexcom G5. Every single morning when I shower, I put my phone within Bluetooth range (about 6ft) and immediately with the water on, my readings go nuts and xDrip+ displays a “High Noise” warning. It takes another 30 minutes or so after showering for the readings to return to normal. ![13%20PM](https://canada1.discourse-cdn.com/flex030/uploads/fudiabetes/original/2X/b/b582dbcc61b7678fe9c6c547af1b502e88f24e0d.png) ![32%20PM](https://canada1.discourse-cdn.com/flex030/uploads/fudiabetes/original/2X/0/03b5e9aeb9ff1e600bd95963ee74d8a47f255302.png) ![44%20PM](https://canada1.discourse-cdn.com/flex030/uploads/fudiabetes/original/2X/b/b37680bf4a216249227e66c469879c2b8fc9f104.png) ---

> [@sanfran](#): > > Has anybody experienced super noisy readings when showering? Yes! @sanfran, we find that we can get noisy readings if the water infiltrates the slot between the transmitter and the sensor. Sometimes (rarely) we even lose the signal for a while. When we remove the transmitter, dry both sides of the contact plates well, then put the transmitter back, we generally get a good signal back. See if that works for you, and let us know 🙂 ---

Yeah, I’ve noticed that but I don’t worry about it. I try not to calibrate right around when I take a shower since that will mess it up. Lately, I’ve just been calibrating once a day when I’m level-ish. On the other hand, if an injection isn’t working fast enough, a hot shower is a nice lazy way to drop quicker… ---

My Dex track always spikes when I take a shower. It will go from 80 when I step into the shower, and by the time I get out it’s gone up 30-50 points. It comes back down pretty quickly, maybe 10-15 mins. Just another Dexcom oddity, not attached to reality. ---

G4 here, and I used to frequently get the ??? during and after showering. I began to tape a plastic sandwich bag over the sensor – just along the top to keep the water off, not sealing the whole thing in – and the problem vanished. One minor nuisance to get rid of another minor nuisance. ---

@Beacher Until the Seven Plus the transmitters were not waterproof. Dexcom provided, for a fee, nifty little stick on shower covers. Something along the same line as you’re doing, just custom fit. They actually worked pretty good. ---

Thank you all for your answers. I’ll clean the transmitter off next time I change the sensor. ---

The G6 spikes in a shower. It also spikes in the bath. The Dexcom app doesn’t show this, or at least doesn’t show it as much, but xDrip+ doesn’t seem to do the smoothing that the Dexcom app does. So far as I can determine it is a skin temperature thing; the shower, or the bath, suddenly raises the skin temperature and the readings go up. I’ve only been using a Dexcom for a few months so I haven’t yet tried the sauna or the jump-into-a-hot-tub experiment but I suspect the readings will go wild. Indeed, even getting out of the car into sub-freezing air has a significant effect. I’m pretty certain that all the Dexcom implementations are basically 100% waterproof. The sensor on the G6 has a grease spot which pretty much stops any water interference at least for the approved 10 day usage and so far as I can see water penetration would certainly cause the sensor to fail - it would simply short it out.

I get as much as a 40mg/dl spike when I take a shower. Within 10-15 minutes of getting out of the shower it goes back down, and generally goes a bit lower due to the heat enhanced circulation provided by the hot shower. I just note it as an artifact with xDrip+ notes. It’s actually quite a trip to watch the track go up and down so quickly!
