The technique described in the article is the common autogenic training [0]. I was taught this when I was a child, althought it was never of much use to me, because it didn't seem to help when I tried to use it before tests or when trying to relax. But it is effective for many people and I was even warned not to do it while bathing, because of a risk of drowning.
