How Understanding Drug Addiction Can Motivate You to Exercise
Much has been made of the “runner’s high,” the euphoria attributed to pleasure-inducing neurotransmitter dopamine and endorphins (the brain’s endogenous opiates) being released in the brain during exercise. But the question is, if exercise causes the same brain changes as do other rewarding activities like, say, taking drugs, why, then, don’t exercisers crave their workouts the way addicts crave drugs?

Porn users describe what it’s like to be hooked Last month, 3000 doctors of the American Society for Addiction Medicine released a public statement bringing the definition of addiction into line with decades of addiction research. “[Addiction] is about brains…. It’s about underlying neurology, not outward actions,” explains ASAM’s Dr. Michael Miller. ASAM’s definition captures […]

Comments: Note that a reduction of D2 (dopamine) receptors is thought to be associated with ADHD. Many men who give up porn see improvements in concentration and focus. Addictions are known to cause a decline in dopamine D2 receptors in the reward circuitry.
If Twinkies and soda can lead to ADD/ADHD, what could watching porn do? I’ve never heard of Twinkies-induced ED at age 21.

[Day 28] I’ve always had porn in my life in one form or another off and on down through years. I never really thought I had a serious problem with it. It if was around, I would view it. But for some strange reason, I just liked watching other people have sex. I think in […]

COMMENTS: This set of frequently asked questions accompanied ASAM’s new definition of addiction. A few of the Q & A’s address sex addiction. It’s quite clear that the experts at ASAM view sex as a real addiction. We see sex addiction (real partners) as quite different from Internet porn addiction (a screen). Many who develop Internet porn addiction would never have developed a sex addiction in the pre-Internet era.

This symptom has been reported repeatedly. It’s likely that premature ejaculation is somehow related to dysregulated dopamine in heavy porn users. We associate porn-induced ED and delayed ejaculation with desensitization or what we call a “numbed pleasure response”. Desensitization involves a decline in dopamine signalling in the reward circuitry.

Comments: study reveals that overeating “cafeteria food” to obesity leads to decreases in dopamine levels and blunted dopamine response to normal rats chow. However, the rats still had reward response to the cafeteria food. One of many studies showing brain changes similar to those addicted to drugs. Over consumption of supernormal versions of natural rewards can lead to addiction.
