You should swear when you hurt yourself. Research into the hypoalgesic effect of swearing has shown that the use of profanity can help reduce the sensation of pain. Swearing in response to pain may activate the amygdala which in turn triggers a fight-or-flight response. This then leads to a surge in adrenalin, a natural form of pain relief. This phenomenon is particularly strong in people who do not use such words on a regular basis.
Paper cuts hurt so much because the cut often bleeds very little or not at all, leaving the skins pain receptors open to the air. This is exacerbated by irritation caused by the fibers in the paper itself, which may be coated in chemicals such as bleach. Additionally, most paper cuts occur in the fingers, which have a greater concentration of sensory receptors than the rest of the body.
When ignored by that person whose attention means the most to you, the reaction in your brain is similar to physical pain.
In a 2008 Duke study, patients received painful electric shocks. Afterwards, $0.10 cent placebo pills alleviated pain for 64% of study participants. $2.50 placebo pills reduced pain for 85% of participants. So it is: expensive placebos work better than cheap ones.
Gingers don’t feel pain to the same degree that everyone else does. Redheads are less sensitive to electrically induced pain, but are more sensitive to thermal pain.
The brain has no pain receptors. Sometimes brain surgery is conducted with the patient awake so that doctors can talk to him or her to make sure the brain isn’t damaged by the operation.
Loneliness is processed in the same part of the brain as physical pain.
Acetaminophen (paracetamol) reduces the pain of social rejection.
The stomach ache a male gets after being kicked in the nuts is caused by the pain traveling up the spermatic plexus (the primary nerve in each testicle), which is connected to your abdominal region.
Cursing actually helps to reduce pain, by raising our pain tolerance.
