Do you think the mind can heal the body? Does it seem possible to you that our thoughts influence the pain we feel or the illnesses we suffer from? If this sounds crazy to you, you may be interested in learning about the fascinating placebo effect.
This is a reality that has been empirically verified on numerous occasions, but it never ceases to surprise researchers and health professionals. If you have had contact with children, or if you remember your own childhood, you will have seen how a kiss from mom or a band-aid produces almost immediate relief from pain, anguish and discomfort.
This also happens to us adults. And it is that, many times, the simple fact of being examined by a doctor produces improvement in our ailments. Or, we even got to feel really more active and clear after having a coffee that, later we found, was decaffeinated.
How is it possible for all this to happen? The so-called placebo effect has been studied for decades and, although its mechanism of action is not yet fully understood, we do have a rough idea of how it works. We will explain more about it below.
What is the placebo effect?
A placebo is any substance, technique or procedure that pretends to be a medical therapy without actually being one. For example, sugar pills that are given after convincing the patient that it is an active medicine. Or acupuncture sessions that are performed without the needles pressing any useful point.
Applied in an appropriate context, these interventions, which do not have any therapeutic properties, manage to improve the health status of the person. In other words, an improvement occurs with a procedure with no real capacity to generate it.
It is estimated that this phenomenon occurs in approximately 35% of the population. However, this percentage can increase depending on various factors. The reputation of the doctor, the healthcare environment or the type of procedure that is applied can influence its effects.
For example, intravenous injections seem to generate the placebo effect to a greater extent than taking medications by mouth.
