Do a search of the forum. There are a couple of long threads about this. Also take a look at this support document about wearing the Apple Watch, Wearing your Apple Watch - Apple Support.
Not everyone can wear the watch, so people are allergic to the components, some find the shape of the watch doesn't work with them. For every person that finds it difficult to wear, there are thousands that experience no problems. You can contact a doctor to see if there is an issue with the way the device sits on your wrist. However, the Watch back is not, "putting off something that directly effects the human body."
And in response to this, "APPLE you need to recall theses devices and correct this issue." You are not addressing Apple here, this is a user to user support forum.
