It comes as no surprise to see science confirm that watching Internet pornography shrivels the brain.
Scientific studies reveal what most Christians already know: your mind, body and spirit are affected by all you do.
The Bible warns that man will not be rewarded for sin, but will indeed reap what he sows.
Men who watch large amounts of sexually explicit material have brains with smaller reward systems, a study finds.
“That could mean that regular consumption of pornography more or less wears out your reward system,” says Simone Kühn, psychologist at the Max Planck Institute for Human Development in Berlin and lead author of the study, published in the “JAMA Psychiatry” journal.
Your reward system is a collection of neural structures in the brain that regulate and control behavior by inducing pleasure.
The researchers scanned the brains of 64 men aged between 21 and 45 with a MRI machine.
Those probands – or study subjects – who watched porn often had a smaller striatum, which is an important part of the reward system and also involved in sexual arousal.
The study also found that the reward systems of porn-experienced men were less active when they watched sexually arousing pictures inside the MRI machine.
“We assume that probands with a high porn consumption need increasing stimulation to receive the same amount of reward,” Simone Kühn says.
Like Cocaine and Gaming
Kühn says the team had predicted it would observe changes in the reward system - but the opposite of what it ultimately found.
The striatum is also involved in drug addiction.
In 2001, researchers found that reward-system-related brain parts were up to ten percent larger in cocaine addicts than in non-dependent probands.
And as if that wasn’t enough: “In a study with teenagers we found that frequent PC games playing leads to an increase in the size of the striatum,” says Kühn. But she notes she was surprised to see that male porn-watchers had smaller – not larger – striatum than the other men in the study.
She says she had expected porn consumption to increase the size of the reward system – rather than make it shrink.
This is the law of diminishing returns in the life of a sinner. God will not be mocked.
