This common sleep disorder is often caused by stress, discomfort, pain, light, noise etc.
It is the inability to fall asleep quickly due to mental or physical problems. So how can a waterbed help? The short answer is relaxation! A waterbed is not a cure but it can provide an environment that helps the problem cure itself. Waterbeds conform perfectly to our bodies which are themselves 75% water. We literally ‘float’ on it so are effectively semi-weightless: So we relax!
Please do not do any self diagnosis but consult with a health professional.
