Got Endorphins?

I’ve been thinking about this for the past week. Last weekend I had some fairly strenuous exercise. Now, don’t get me wrong, it wasn’t running a 20K or playing basketball all afternoon. I’m referring to the 6 mile hike Sandi and I took, followed by cutting and loading a pickup load of wood by myself. Yes, I worked up a sweat. Yes, I was tired. But the odd thing was that I haven’t felt that invigorated in a long time. No legal or illegal drugs, no alcohol. Maybe it was a sense of dementia setting in; after all, I did go skinny-dipping on the way home too.

No, I think it was the endorphin production that my body was experiencing. Now, I’ve heard peripherally about endorphins, but don’t know a whole lot about the subject. I can look back and see where I have experienced feelings of euphoria and yet calmness. Whenever I go for a hike in the woods, it is for the most part, as Sandi would term it, “like the Bataan Death March.” Which I must disagree too, but I do enjoy just going, and do push myself, but it’s all in the name of enjoyment. And, to a degree that I don’t understand, almost a crazed addiction. I crave that feeling. I want to see, to experience, to be part of the natural world. Getting out in the woods affords me an opportunity to a small degree, the ability to “scratch that itch.”
The release of endorphins lowers the blood pressure, a major indicator in heart disease, and has even been implicated in the fight against cancer. Also, endorphins are best known to those who exercise a lot, and give rise to what is known as the 'runner's high.’ The release of endorphins also has been found to lower blood pressure, a major cause of heart disease. Evidently, they’re released whenever there is a certain amount of pain involved. Maybe though that is the key; to encourage the release of endorphins while staying just outside of the pain or injury range. Whenever I lift weights I have this same good feeling, because whenever I’m done, I feel great. Weightlifting’s purpose is to microscopically tear muscle tissue to grow back as increased muscle mass.
I found that Endorphins are a class of neurotransmitters produced by the body and used internally as a pain killer. This class of compounds are similar in their action as opiates, attaching to some of the same receptors in the brain. Now, I haven’t taken opium, but I have to believe that there are similar reactions to endorphins and opium. They are a strong analgesic, and thus are the bodies own built in pain-killer, and, the best thing, give a pervasive sense of happiness.
I guess the good news is that while I can’t experience a sense of euphoria from exercise all the time, chilies can also release these compounds without too much strain or stress on the bod. I know, I know, too much thinking.
