Does stress affect memory?
Stress can cause acute and chronic changes in certain brain areas which can cause long-term damage. Over-secretion of stress hormones most frequently impairs long-term delayed recall memory, but can enhance short-term, immediate recall memory.
How does porn affect the brain?
Porn may also literally shrink the brain, a 2014 study in the journal JAMA Psychiatry found. Men who regularly consumed porn had smaller brain volume and fewer connections in the striatum, a brain region tied to reward processing, compared with those who didn’t view porn.
What does tolerance mean in drugs?
Tolerance happens when a person no longer responds to a drug in the way they did at first. So it takes a higher dose of the drug to achieve the same effect as when the person first used it.
