Recently Obsidian and I were watching a National Geographic Special all about stress. (Did I mention, we are geeks
) Anyways, it was really interesting. The majority of it was devoted to research of baboons in the wild and British civil servants. I guess baboons have a very complicated hierarchical social structure, do not need to devote much time in obtaining food, so they have a lot of time, as the researcher said, "to make each other miserable." They also used British civil servants because they have a complex hierarchy, but all have access to the same health care, so they could rule out differences in access to health care. Not surprisingly, they found that those on the lower end of the social structure of both baboons and British civil servants showed far more damage from stress than those higher up.
Anyways, what they found is that stress is far more physiological and hormonal than psychological. It is a mechanism for protecting us from predators and for catching prey. All of our body functions are devoted to giving us a short burst of energy to either catch our meal or to avoid becoming one. Other functions, such as higher reasoning and our immune system shut down, because we do not need them if we are running to avoid being eaten by a lion, because it is short period of time in which it is either over or we are over, because we are dinner. The problem is, as one of the researchers stated, "we get stressed out by stuff that no zebra running for its life from being eaten by a lion would ever understand." We often live under constant stress, which is really bad for our bodies, because they were not designed to function under the hormones involved for long periods of time.
Anyways, how this relates is that, yes, a spanking might provide enough relief in order to stop the stress response. Other the other hand, it might intensify the stress response. It depends on the person. For me, sometimes they work, and sometimes they don't. If I expect Obsidian to notice I am stressed and give me a spanking, this creates more stress, because then, well, it may or may not happen...if this makes sense. Also, in this instance, you will probably need some control in order to cope, rather than adding to the stress response. When I ask for a spanking to relieve the stress response, and Obsidian gives me one, then it is far more likely to be calming. I agree with Jigsaw, even if spanking helps you, and even if your partner is willing to give you such spanking, your partner will not be available for spanking 24/7...and may not always have the energy or being in headspace to help, so I would use it as one tool among many, if this makes sense.
Good luck to you!
