Hi, I have searched for answers to this problem for a long time and cannot find any, other than that a cellar means a kind of black hole of energy or a pit etc. I am living in a house with a large cellar / basement under the living room, which is inaccessible. It has been sealed off with concrete, but not filled and there are vents from the cellar into the living room floor. The property is rented so there is no chance of opening up the space to make it useable. Despite eating healthily and generally looking after ourselves ( we don't drink much alcohol etc) we do, as a family seem to be getting I'll a lot - particularly stomach upsets etc, which I have read can be related to cellars. I live with my husband and 3 year old daughter. We would greatly appreciate any advice. Thankyou.
