Sometimes and only sometimes it has been the case that sleeping on it when you have been in many days if you sleep about it can increase the difference in values ​​but will never stop working for that.
You can bathe in the bathtub or beach as many times as you want, the sensor assures well.
I also advise you to talk to the laboratory and share opinions with them, they will also tell you very well.
I close the thread to avoid duplication.
