Why Nothing Feels Fun Anymore: Dopamine, Phones & Brain Rot

Your phone is not just distracting you, it may be changing what your brain finds rewarding.

In this episode of Dr Karan Explores, Dr Karan Rajan speaks with neuroscientist TJ Power, founder of DOSE Lab, about dopamine, phone addiction, AI, “brain rot,” digital anhedonia, and why modern technology can make ordinary life feel less pleasurable. TJ’s DOSE framework focuses on dopamine, oxytocin, serotonin, and endorphins, the four brain chemicals he says are being disrupted by the way modern humans live.

This conversation explores why so many of us feel stuck in loops of scrolling, distraction, apathy, and low motivation, and what it takes to reset our relationship with stimulation without pretending technology is “bad.” TJ shares why he believes 72 hours without screens can feel transformative, why boredom is harder than it sounds, and why becoming a “professional unplugger” may be one of the most important skills for the next generation.

In this episode, we cover:

• What dopamine actually does beyond the online “dopamine detox” clichés
• Why phones, short-form content, sugar, alcohol, and AI can hijack reward pathways
• “Digital anhedonia”: Why normal life can start to feel dull or boring
• The 72-hour unplugged experiment and what happens by day two and day three
• Why boredom, stillness, walking, and doing nothing can restore creativity
• The default mode network and why your best ideas may need silence
• AI, “brain rot,” passive screen time, and outsourcing your thinking
• How to become a “professional unplugger” without quitting modern life
