"Dopamine fasting" is a misnomer for stimulus control that can backfire for those with ADHD and anxiety. For brains already low on dopamine, drastically cutting off stimulation can worsen symptoms and lead to a powerful rebound.

The phrase "dopamine fast" is just a catchy, science-ish rebrand of an old therapy technique: stimulus control. The idea, which came from Dr. Cameron Sepah, isn't about lowering your dopamine. It's about taking a break from easy, cheap highs—endless scrolling, gaming, online shopping—to get a handle on impulsive behaviors.
For most people, stepping away from the phone is probably a good idea. But for someone with both ADHD and anxiety, the game is different. The wiring in your brain just isn't the same.
ADHD is a story about dopamine. Brains with ADHD often have more dopamine transporters, which are little vacuums that suck the chemical up too quickly. The result is a lower baseline level of dopamine, which messes with focus, motivation, and emotional control. This is why many people with ADHD are drawn to high-stimulation activities; they're subconsciously trying to push their dopamine up to a level where they can function.
Anxiety's relationship with dopamine is more complicated, but low levels can make anxiety and mood swings worse. The brain’s reward system runs on dopamine, driving you toward what feels good and away from what doesn't. When that system is unstable, it can feed both the reward-seeking of ADHD and the avoidance of anxiety.
So what happens when you tell a brain that's already fighting to stay balanced to cut off its main sources of stimulation?
It usually doesn't go well.
Forcing someone with ADHD and anxiety into a low-stimulation state is like taking a crutch from someone with a broken leg. The things they're "fasting" from might be the very tools they're using to manage.
Cut off those coping mechanisms, and things can get worse. Anxiety can spike. Irritability goes up. The boredom can feel so overwhelming that it becomes impossible to focus on anything.
Extreme restriction almost always leads to a rebound. I tried a "digital detox" once, locking my phone in a timed safe for 24 hours. The first few hours were fine. Then the restlessness hit. By the next morning, the urge was so intense that when the timer finally clicked open, I fell into a five-hour scrolling vortex that left me feeling worse than before.
That's not a failure of willpower. It's what happens when you starve the brain of something it needs. It will overcompensate the second it gets the chance. For someone with ADHD, this just reinforces the all-or-nothing cycle they were trying to break in the first place.
The goal isn't to eliminate everything, but to be more deliberate. It's not a fast; it's learning to build a better media diet. You don't stop eating, you just learn to choose things that actually nourish you.
The impulse behind the dopamine fast is a good one. It's smart to manage impulsive behavior. But for anyone with ADHD and anxiety, a rigid, all-or-nothing fast can trigger the very problems you want to solve. The real work isn't about fasting from a brain chemical, it's about figuring out how to live in a world of infinite distraction without letting it run your life.
