What is a negative placebo effect like?

The placebo effect can have a negative influence also, a nocebo. If a placebo is given that the patient believes to be harmful to their health in some way, he or she may develop symptoms appropriate to this belief.


What is the nocebo effect?

The nocebo effect is basically the opposite of the placebo effect. It's when people experience pain, illness or die when they aren't really sick, they just think they are, expect to be, are in an environment where sick people would usually go e.g. a hospital or even see someone else who is sick from something possibly contagious. -Sira

What damage do communication masts cause to children?

There's no solid evidence either way, although research has shown three things: 1. Irradiation of cells in culture with mobile-phone frequency EM signals does seem to change the expression of proteins, although it's not certain why or what effect this has on the cells 2. One of the most significant findings from the many trials aiming to solve the question is that people claiming to be sensitive to EM irradiation (complaining of anxiety, nausea and malaise around phone towers) seem to suffer these symptoms whether or not they are actually turned on; suggesting that a large proportion, but not necessarily all, of the alleged ill-health caused is actually a result of the nocebo effect. Additionally, many large-scale studies have found little or no evidence of a link between cancers and time spent near phone masts. Similar results have been recorded for those who spend large amounts of time exposed to strong EM signals, such as electrical engineers and military radar workers. 3. You're too lazy to type "mobile phone masts health effects" into google.


Are some diseases caused by evil spirits?

== == A case could be made for an evil spirit causing a disease if one considers that certain types of mental illness qualify as a disease. An evil spirit, either a real or an imagined one, could so affect an individual that he is driven to, say, some kind of psychotic break. The critical question is this: will that person's health insurance cover treatment? Centuries ago yes, in some countries it was considered if a person became very ill such as a high fever, was moaning and groaning they were possessed by demons, evil spirits or even witches, only out of ignorance because they didn't understand about new diseases that they had no control over at that time. Now in modern times we realize that some diseases are genetic in factor or caused by other problems such as our environment for one, and there are many treatments for most diseases. However, new diseases are surfacing all the time and will continue to do so. Cures must be found. The above poster left a good post as far as psychological aspects to whether one believes a demon or evil spirit is the cause of their disease. Unfortunately, some religious cults will have you believe that if you are suffering from some form of mental illness (quite common in modern times) that indeed it has to be caused by demons that have entered the body. This is simply not true. For a so called "evil spirit" may be thought as the cause of a disease, the person targeted must believe in evil spirits. It has not been proven the existence of such entities, however, if someone believes that they do exist, a phenomena called Nocebo (reverse placebo) can occur, causing that the believer experience the symptoms of an illness. However, this is a psychogenic creation of the subject's own mind. No! Disease is caused by your thoughts, and so is health. You can find reference to which thoughts relate to which maladies in the book "Permanent Healing". I will provide a link for you. I have much personal experience with this process.
