Neuroscientist Explains: Replace Doomscrolling With Video Games

Summary

Neuroscientist TJ argues that, for some people, a purposeful gaming session may be a healthier alternative to doomscrolling. His central distinction is between fast dopamine—rapid, repeated stimulation from short-form feeds—and slow dopamine, which builds through effort, strategy, exploration, and a sense of accomplishment.

He cites studies suggesting that gaming may support brain structure, creativity, social connection, and life satisfaction. But he stresses that the benefits depend on the game and how long you play: one study found the most positive outcomes among young people who played just under an hour a day, while playing more than three hours was associated with poorer well-being and more social or emotional difficulties. Gaming should complement—not replace—other healthy activities.

Strategies and tips

• Choose games that reward sustained attention and effort. Look for clear goals, problem-solving, exploration, creativity, and a satisfying sense of completion.
• Prefer slower, less stressful play. Fast, highly stimulating games may leave you agitated or angry; consider how a game affects your mood and nervous system.
• Look for social or cooperative play. Playing with friends or family can add conversation, laughter, and shared enjoyment.
• Be cautious with games built around rapid novelty or spending. The speaker flags endless game-hopping, mobile-game stimulation, paid packs, and gambling-like reward loops as potential pitfalls.
• Set a time limit. The speaker suggests using about an hour a day as a possible target, based on the study he discusses—not treating longer play as automatically beneficial.
• Build self-control through exercise. He describes a 2025 randomized trial in which progressive aerobic training reduced gaming cravings and addiction severity, potentially by strengthening brain networks involved in control and reward.
• Pair gaming with other rewarding activities. He recommends balancing it with other healthy hobbies rather than relying on gaming alone.

Games discussed, from least to most brain-friendly in the speaker’s view

1. Roblox: Endless switching between games and pressure to spend.
2. Candy Crush and similar mobile games: Quick stimulation and frequent interruptions; he generally advises avoiding mobile games for this purpose.
3. EA Sports FC pack-opening: Randomized rewards can resemble gambling-style reward cycles.
4. Modern Call of Duty: Fast and stressful, and potentially agitating.
5. Fortnite: Social play can be a plus, but it remains highly stimulating and includes pack-opening features.
6. Mario Kart: Clear rounds, concentration, and potential for shared play.
7. Call of Duty: Black Ops 1: Presented as slower and more social than newer entries.
8. Minecraft, especially Survival mode: Encourages creativity, effort, cooperation, and problem-solving.
9. Zelda (and potentially Red Dead Redemption 2): Slower, exploratory, and more methodical.
