You are given two pills and told that the first is a regular medication and the second is twice as effective. In truth, both pills work the same, but you feel greater relief from the second one. This is called the placebo effect; when your experiences are influenced by your beliefs, even when the reality is different.<\/p>\n\n\n\n
A placebo treatment is when a subject acquires a dummy treatment and believes they are receiving one that truly works. The placebo effect is when the subject who received the placebo actually improved their symptoms, or at least thinks their quality of life has improved. These changes in symptoms are due to the person believing they are receiving a real, effective treatment.<\/p>\n\n\n\n
The placebo works because of the expectation of improvement<\/a> that can alter a person\u2019s perspective of their illness. When someone truly believes that they are being helped by a treatment, regardless of the form that treatment comes in, their brain can release specific hormones called endorphins and dopamine. These hormones can overall make the person feel less anxious, reduce pain or stress and overall create a better feeling. The placebo effect isn\u2019t imaginary; it\u2019s a real physical reaction triggered purely by belief. Throughout your life, taking a pill or treatment is correlated with the feeling of improved symptoms. This makes it so that even when your treatment isn\u2019t real, the association of the mind changes the feeling of the body. <\/p>\n\n\n\n Researchers frequently use placebos in experiments to make sure that the treatment actually works, and isn\u2019t just benefiting from people\u2019s expectations. Usually, one test group receives a placebo while the other test group receives the real treatment. Neither the scientists nor the participants know who is in which group. This is called a double-blind trial<\/a> because it rids the experiment of bias and effectively shows if the drug produces a real effect. If the drug\u2019s effects don\u2019t have a substantial difference from the placebo effect, then it is a clear sign that the medication isn\u2019t working. <\/p>\n\n\n\n The placebo effect isn\u2019t only impactful in the lab; it shows up in everyday life more often than most people realize. One way the placebo effect is commonly experienced is feeling better after taking medicine immediately after taking it. Medication does not work immediately upon consumption; it takes time to kick in. It is common to feel improvements shortly after taking the medicine because you expect to feel better, and so you do. Other examples of this are students performing better while using a \u201clucky\u201d pencil or feeling better after placing a Band-Aid on a small cut. Even though the treatments don\u2019t actually work, the change comes from the belief and confidence it creates. <\/p>\n\n\n\n The placebo effect informs us about the unique connection between our minds and our bodies, and how our thoughts can change our physical experiences without us noticing. It demonstrates that believing in something isn\u2019t always \u201cjust a feeling,\u201d it can actually create a biological impact, from the release of hormones to changing the immune system as a whole. This obviously doesn\u2019t mean that our thoughts can cure diseases, but it does show that our thoughts have genuine impacts on our experiences. A placebo can lead to improvements even without doing anything. If two people had the same symptoms and one was given a placebo, and the other nothing, you could expect the outcomes to be different. Neither was genuinely treated, but the placebo receptor may experience a change in symptoms while the other stays the same. The only difference is that one believed that they were getting better, and the other did not.<\/p>\n\n\n\n
