Where It should take about 30 minutes for the aspirin Manny just took to relieve his headache, but Manny feels better within minutes. This is an example of "the placebo effect."
<h3>What is a placebo Effect?</h3>
The placebo effect is a phenomenon in which a person's expectations or beliefs influence their perception of pain or other symptoms. A placebo is a substance or treatment that has no real effect on the condition but is given to the person as if it does. For example, a placebo pill may look like a real medicine, but it contains no active ingredient.
Sometimes, just taking a placebo can make a person feel better because they think they are receiving a helpful treatment. This can reduce their stress, anxiety, or negative emotions, which can affect their pain or discomfort.
The placebo effect is not a sign of weakness or imagination. It is a real psychological and physiological response that can be measured and observed.
The placebo effect can also work in the opposite direction. If a person expects treatment to have harmful or unpleasant side effects, they may experience them even if the treatment is harmless. This is called the nocebo effect.
Some possible examples of the placebo and nocebo effects are:
- A person with a cold drinks a cup of herbal tea and feels less congested, even though the tea has no effect on the virus.
- A person with a headache takes a sugar pill and feels less pain, even though the pill has no analgesic properties.
- A person with insomnia listens to a soothing sound and falls asleep faster, even though the sound has no effect on their sleep cycle.
- A person with allergies eats food they think they are allergic to and develops a rash, even though the food has no allergens.
- A person with depression takes an antidepressant and feels more depressed, even though the antidepressant has no negative effect on their mood.
- A person with high blood pressure takes a blood pressure medication and feels dizzy, even though the medication has no side effects.
