Your brain is fried by short-form video. Your dopamine receptors are overworked. The fix is a dopamine detox: no phone, no socials, no music, no junk food, no caffeine, just walks and water for 24 hours, 48 hours, ideally a week, until your brain remembers how to enjoy boring things again. Andrew Huberman talks about it. Wellness influencers built whole careers on it. It even sounds plausible: too much fun broke you, less fun will fix you.
Dopamine is not a feel-good chemical that gets used up and topped up. It's a neurotransmitter mostly involved in motivation and prediction-error signalling, the brain's way of saying 'pay attention to this, it might be important.' You cannot drain it by scrolling. You cannot reset it by abstaining. Receptor density and sensitivity do change with chronic stimulant use (proper drug addiction, not Instagram), but those changes happen over months, not days, and don't reverse with a long weekend off. The framing also gets the science backwards: dopamine spikes are involved in *both* the doomscroll and the hike. The original UCLA paper that started the trend was about general behavioural cognitive therapy, not dopamine. Taking a break from your phone is genuinely fine. Calling it a dopamine detox is roughly as accurate as calling sleep a serotonin reboot. The thing that helps is the rest. The neuroscience is decoration.
