The prefrontal cortex acts as the brain's 'braking system,' allowing you to stop a pleasurable activity and initiate a necessary one (like putting down the phone and turning off the light). This stopping power requires psychological fuel. After a full day of forced productivity, you suffer from 'ego depletion'—the complete exhaustion of willpower.
At 1 AM, when the video auto-plays the next episode, you mathematically lack the inhibitory control required to press the pause button. The dopamine loop of the screen is exponentially stronger than the depleted 'stop' signal of the prefrontal cortex.
Furthermore, ADHD is highly correlated with a 'Delayed Sleep Phase Syndrome' (DSPS). The biological circadian rhythms of the ADHD brain are often shifted 2 to 3 hours later than average. While a neurotypical brain begins dumping melatonin at 9 PM, the ADHD brain does not start winding down until midnight. When society forces you to operate on an 8 AM schedule while your biology demands a 2 AM schedule, extreme chronic sleep deprivation is the inevitable biological result.
