Teens with a history of self-harm have a significantly highe
New research has found that teenagers who have self-harmed five or more times in their life have a significantly higher threshold for pain compared to adolescents that have not.

64 participants aged between 12-17 were recruited from a mixture of community and residential care settings, as well as schools and youth groups. Each individual underwent a series of 13 tests, including thermal detection and pain thresholds, and pressure pain thresholds to establish at what point they detected a change in sensation or first began to feel pain.

"From the studies that we conducted, we can see that teenagers who have self-harmed five or more times in their past have a dramatically higher pain threshold, particularly in individuals that are living in care."

"Once a person has become comfortable enough with pain when they have raised the threshold far above what it would normally be in someone that hasn't self-harmed, it is at that point we can say that they are at greater risk of suicide."

The findings of this study suggest that sensory hyposensitivity is a phenotype of Adolescents who self-harm and that pressure pain threshold has clinical potential as a quick, inexpensive, and easily interpreted test to identify adolescents at increased risk of repeated self-harm.
