How Understanding Drug Addiction Can Motivate You to Exercise

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?

I’m not an addict. What happens if I “reboot?”

Two types of brain changes may occur when you use Internet porn: psychological and addiction related. Both involve neuroplastic alterations in the structure of nerve cells and their connections. No clear line separates psychological from addictive changes. Is it conditioning, or a “numbed pleasure response”, that has someone craving a particular fetish or genre of porn? Or is it both?

Deficits of mesolimbic dopamine neurotransmission in rat dietary obesity (2009)

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.

Enhanced Reward Sensitivity and Decreased Loss Sensitivity in Internet Addicts: An fMRI Study During a Guessing Task (2011)

COMMENTS: One of several new studies indicating brain changes mimicking those found in drug addicts. Study does not say what type of internet addiction it measured. Was it all encompassing Internet addiction, including porn, or was it only Internet video games?

Gray Matter Abnormalities In Internet Addiction: A Voxel-Based Morphometry Study (2009)

COMMENT: Adolescents with internet addiction have decreased gray matter in portions of the frontal cortex. Decreases in size and functioning the frontal cortex are found in all addiction processes. I wonder about the extent of porn use in the Internet addiction group. Another example of a non-drug addiction causing brain changes similar to substance abuse disorders.

Overlapping Neuronal Circuits In Addiction And Obesity: Evidence Of Systems Pathology (2008) Nora Volkow

COMMENTS: By Volkow, who is the head of NIDA. Real simple – food addiction parallels drug addiction in addiction mechanisms and brain changes. More proof that food addiction can alter the brain in the same way that drugs can. Our question – if food can cause addiction, how can masturbating to porn not be potentially addictive? Especially considering the fact that porn use is far more stimulating and longer in duration than eating.
