NoFap
Nofap is the practise of intentionally abstaining from masturbation and porn for a longer period of time. In modern society porn is accessible like never before. There are hundreds of genres, fetishes and other non natural categories. Each time porn is viewed, a rush of dopamine rewards the brain which will lead to an addiction and its effect on the brain is similar as to some drugs<1>. This rush of dopamine causes the dopamine receptors to get blocked in the brain, leading to a tolerance<2>. This tolerance will have negative health effects mentally and physically depending on how strong the addiction has delevoped<3>.
Possible effects on Polyphasic Sleep Adaptation
The tolerance to dopamine that porn addiction has created in people, will lead to a general loss of motivation in daily life. When sleep deprived during an adaptation, motivation is needed to not oversleep, therefore a porn addiction can cause more difficulties during an adaptation and reduce the chance to adapt to a schedule.
