If you're interested in things that affect your health you've probably heard of the placebo effect - where expecting that a drug will work, even when it's just a dummy pill, can actually make it effective.
How fascinating is that? And to make matters even more interesting, some of the volunteers were told they were being given a powerful painkiller. And in those cases, the effectiveness of the pills were doubled.
The volunteers were all given a powerful, fast-acting opiod painkiller called remifentanil, so it should have worked in all the volunteers. It was administered through a drip, so they couldn't tell whether or not they were getting any drugs.
The participants had to rate their pain levels after being given the drug - with those who had been told they were getting a dummy drug, or no drug at all, reporting little to no change. The scans also showed differences in brain activity in those who were told they were being given a painkiller and those who were told they were not.
The researchers claim this shows that if you have positive thoughts about painkillers - or, in theory, any type of medicine - it could work twice as well.
Do you think mind over matter is important where health is concerned?
