Detailed explanation-1: -The placebo effect is when a person’s physical or mental health appears to improve after taking a placebo or ‘dummy’ treatment. Placebo is Latin for ‘I will please’ and refers to a treatment that appears real, but is designed to have no therapeutic benefit.
Detailed explanation-2: -The placebo effect is when an improvement of symptoms is observed, despite using a nonactive treatment. It’s believed to occur due to psychological factors like expectations or classical conditioning. Research has found that the placebo effect can ease things like pain, fatigue, or depression.
Detailed explanation-3: -For example, if you’re regularly given the same arthritis pill to relieve stiff, sore joints, you may begin to associate that pill with pain relief. If you’re given a placebo that looks similar to your arthritis pill, you may still believe it provides pain relief because you’ve been conditioned to do so.
Detailed explanation-4: -The idea that your brain can convince your body a fake treatment is the real thing-the so-called placebo effect-and thus stimulate healing has been around for millennia. Now science has found that under the right circumstances, a placebo can be just as effective as traditional treatments.
