It turns out there is a neurological explanation for why people scratch and cut themselves, and spank each other for pleasure. Inflicting small amounts of physical pain, whether from scratching your skin vigorously or doing something more extreme, deactivates the parts of your brain associated with unpleasant or painful emotions. Though scientists have long speculated that there was some kind of neurological payoff from self-inflicted pain, a study published yesterday demonstrated precisely why your brain gets a reward when you hurt your body.
The study focused on scratching, which is a common, slightly-painful thing that everybody does to relieve itches. Researchers stuck people in an MRI brain imaging machine and scratched their legs with brushes for five minutes, watching to see which parts of their brains were active or non-active. Areas associated with painful feelings became less active, as well as areas associated with memory. The researchers say:
We know scratching is pleasurable, but we haven't known why. It's possible that scratching may suppress the emotional components of itch and bring about relief.It's also possible that the pain of scratching, or more intense pain from cutting, suppresses painful memories too.
The researchers suggest that further study might reveal a way to produce a drug that has the same effects as scratching or cutting does on the brain — thus preventing physical damage while providing the same relief.

Put the lotion in the basket.
This is good news. Now when I'm being flogged by my Master, I'll know that I enjoy it because it's a neurogical feeling as opposed to me being perverted (in a good way).
When is the Folsom St Fair again?
ok, for self-destructive people who are cutters or who don't know when to stop, that's fine. But I don't want to see some pill being pushed as a "cure" for people into S&M.
All right, but technically, this still doesn't explain why small amounts of pain make you feel better, it's just a more complex explanation of how.
What I mean is, scientists still don't seem to know what the hell it's for.
@braak: maybe if you're being attacked or eaten by a predator, it helps to stop thinking about how you 'feel' about it, so that you can run for your life?
@braak: Jesus did it. Or... a wizard.
wait, being in pain is distracting? Thank god for science.
One of the better explanations I've heard for self-harm is that it takes the mental pain/anxiety/depression and turns it into something physical. At least that's the one that seems to apply for me. That, and in a weird way, I think I deserve it.
No, I don't slit my wrists. I tried once and all I got was razoburn and the shit scared out of me.
"Hurt" by Johnny Crash just about makes me cry. I know he wasn't the original artist, but that song is just so sad and poignant.
Is this like when I forgot how I got my last tattoo?
@Biggrz: @Pope John Peeps II: All very good reasons!
@braak: Honestly, I don't think it's the pain that makes you feel better, it's the endorphins released when you encounter pain that make it feel good. It's classical conditioning - you have pain, you body makes its own opiate to dull the pain, which feels better and gives you that little high that you brain digs, so you want to feel the pain again.
Duh- All destructive habits do this- it's the same with compulsive shopping or gambling- it reconfigures an uncomfortable present by rupturing the "now". I could have told you that, and I am certainly not a neuro scientist.
@J.D.Regent: Would need more information. I assume (perhaps incorrectly), that alcohol was involved? In Mexico? ;)
Anything that masks pain can take on an addictive quality, as well as enhancing the already addictive qualities of drugs/alcohol.
@templedrake: Well, yeah. But having a guy just *tell* you something doesn't have quite the same weight to it as proving it with science.
I mean, people tell me stuff all the time, but that doesn't mean I should believe it.
@NefariousNewt: That's what I've always assumed. I just get my knickers in a twist when some scientist says, "Oh, we've figured out why this happens!" And it turns out that they just don't speak English very well, and can't tell the difference between "why" and "how."
I've tried being spanked, and the only thing it did was make me laugh. It either works for you or it doesn't.
This does nothing to explain why I have a special scratchy point on my back that only feels good when it is scratched by a lover.
Maybe that place is connected to a certain painful memory that I need to forget when I'm with a lover?
[Like the fact that I haven't really tested myself for anything since 2001?]
@lalaland13: It turns it into something physical and controllable - the latter is very important, I think.
@langtry: Yes, well, those would be the choices.
@langtry: but it's that laughing/crying/on the edge of losing control feeling that so many people get off on...
This study was just about scratching. You made quite a leap to get from scratching to, uhhh, S&M behavior. I think I like you. :)
Stupid article. Now my back is itchy and I can't reach it.
@braak: I'm not a guy. Does that make a difference? Ha.
I can get a pain-buzz, from lifting weights. Lots of people become endorphin freaks because of this pain-pleasure relationship. As for itching, I got poison ivy-ed this last year and I could make it stop itching with very hot water. The point at which pain over-came itching was almost orgasmic. I also think the shock of jumping into ice-cold water is a pain-pleasure thing. until you freeze to death and die.
@templedrake: Not really.
So... they want to create a pill that will suppress memory and pain receptors? Is the end goal of science to rid us completely of all those yucky things like emotions and senses and anything that makes us human?
@rocknrollunicorn: Yes? What do I win?
@braak: You're so cutting and witty. I can hardly fucking stand it.
@templedrake: Oh, whoah, ouch.
Which one is Braak, the pretty girl or the wild boy?
This article is for you, emo kid.
@Jeff-Minor: The wild boy. The pretty girl is Miranda.
@braak: They speak English just fine. They've figured out why you get pleasure from hurting yourself (answer: this neurological reaction takes place). Getting upset because they didn't tell you why this neurlogical reaction exists is silly, because they never claimed to have the answer to that question.
@templedrake: The fact that your moniker is Temple Drake means that you could basically say anything to me and I would happily listen. I might even bring along a corncob.
@Morgan: I'm not sure about that. Typically when you're using "why" you're using it to say "to what reason," or "for what purpose." Describing the mechanism that results in it doesn't describe the purpose behind it. It does describe the reason that leads to it, but not the reason that it satisfies. Instead, it describes the "how," the "by what method" or "as a result of what reason" of the situation.
@Jeff-Minor:
I know exactly what you mean about the hot water and the itch. Nothing stopped the itch like nearly scalding water.
It's a little shocking though that it took research to realize that pain distracts from other things.
@braak: "Why" can be "as the result of what cause" in addition to "for what reason." When someone asks "why is the sky blue," "because light refracts in the atmosphere in such a way as to reflects blue" is a perfectly valid answer even though it doesn't indicate any reason or purpose for the sky being blue. Indeed, it's the only type of answer one could give to that question unless you want to invoke some sort of god (ie, "because Zeus wants the sky to be blue," or "because God made humans to have this neurological reaction"). Clearly, a scientist cannot answer that way; since there is no observable intent behind either the color of the sky or the evolution of human neurology, a scientist can only answer as to what causes these to occur. The question you may want answered is "why did this evolve" or, more specifically, "what made this a trait beneficial enough to increase the fitness of those that have it," but that really isn't the question they claim to have answered.
@braak: From an evolutionary perspective, it seems to me it might be beneficial to develop a trait that lowers painful feelings WHILE YOU FEEL THEM. Helps you cope in the moment with pain. Sort of a crude version of what the characters in Iain M. Banks novels do when they "gland" painkillers stored in their brains while fighting so that they don't have that pesky pain holding them back.
@Annalee: That is certainly a potentially valid reason.
@Morgan: All of this, of course, is simply an exercise in tetrapyloctomy. The fact is that I was just expressing my dissapointment over what I perceived to be ambiguous phrasing--a phrasing that I maintain scientists continue to use despite the fact that it's ambiguous. Since evolutionary scientists are making statements all the time about "why" things come about, it stands to reason that there'd be at least some effort in establishing a difference between the word we use to describe the mechanism behind something, and the word we use to describe what that thing is for.
This study is kinda pointless. They didn't measure why or how continuous scratching/pain inducing will eventually revert to just being painful again. I'm all for biting and scratching and whatnot, but at a certain point, my sides and back are too scratched up to feel good anymore, and biting too deep hurts like hell.
Or not that it feels "good" or "bad", it just feels different. Look at the average cube dweller. If some does/feels the same thing for too long, anything different feels better even if it really doesn't. If you sit at a computer going online all day, every day for a week, you get bored and numb, so that magazine you see in the corner of your eye, even if its the same damn thing as a website, becomes a beter feeling option.
Science has the ability to answer questions up to a point, then someone says that's all they know. Why a human has a neurological response can be boiled down to nerve impulses. How those impulses are interpreted in that brain fall within a range. People can become addictied to some of their select natural brain chemicals. There are fear junkies, sex addicts, and then the list of ways to get high is too long to bother with. We seem to have a built in desire to play with our own feeling states. Turning pain or fear into pleasure is just getting some of us ready for Hell.
@lalaland13: If I watch the video it breaks my heart and I cry like a baby.
I don't like the sensation of pain in kinky stuff, so much as the mental stuff going on.
pleasureble pain is like scratching. it hurts but it releives that urge, somehow making it feel good. eating spicy food is similar, it's "painfull" yet it's good! could it be a some sort of addiciton to the adrenaline rush as it's secreted from our adrenal glands? the release of dopamine(c8h11n02)& serotonin (c10h12n20)also come into play. are we all just chemical junkies?-blurey
