TikTok's 'Brain Stacking' Trend Is A New Way To Spend Less Time On Your Phone

Let's be real: How many times have you opened TikTok to watch a quick video, only to realize you've been scrolling for the past 40 minutes? One minute, you're watching a girl share her dating drama (with multiple parts, mind you!); the next, you're deep in a rabbit hole about a celebrity you've never heard of. Relatable, but also... damn, where did the time go? 😵‍💫

That's where TikTok's latest wellness trend, brain stacking, comes in. The idea is to swap some of that screen time for activities that get you thinking, creating, or simply focusing on one thing at a time. We're talking reading, journaling, solving puzzles, and picking up hobbies that don't require you to stare at another screen.

Curious about what brain stacking actually involves? Here's what you need to know about it:

Brain stacking involves setting aside time for activities that engage your mind, like reading, journaling, solving puzzles, or drawing, instead of automatically reaching for your phone. On TikTok, creators often share their stacks of books, notebooks, and brain games, with routines ranging from a few minutes to around 45 minutes.

TikTok creator Mandy Rulez has helped popularize the trend, inspiring others to build their own routines around books and brain games. It's also in line with the growing interest in analog living, which encourages people to spend less time on screens and more time enjoying offline hobbies.

The best part? There's no set list of activities to follow. Whether you prefer romance novels, sketching, or crossword puzzles, the goal is to have something enjoyable to turn to when you're tempted to scroll out of boredom.

Swapping some scrolling time for books, Sudoku, or crossword puzzles gives your brain something different to work on. And there may be benefits beyond having a new hobby to obsess over. Research suggests that mentally stimulating activities may help support cognitive health as we age, although scientists are still figuring out how much they can do to prevent cognitive decline.

So, should you start doing Sudoku every day? Go for it if you enjoy it—just don't expect brain stacking to be a magic fix for brain rot or a guaranteed way to prevent dementia. The evidence on everyday brain games is still mixed, and the benefits of structured cognitive training don't necessarily translate to every puzzle app or crossword you pick up.

That said, brain stacking can be a fun way to spend your free time if you're trying to cut back on screen time. Instead of automatically opening TikTok whenever you're bored, you can pick up a book, work on a puzzle, or try a creative hobby.

Want to give it a go? You don't need to buy anything new or dedicate an entire hour to your routine. Start with what you already have and make it work for your schedule.

1. Pick three activities you actually enjoy. Choose a mix of hobbies that keep you engaged without feeling like homework. You could read a few pages of a novel from your TBR pile, spend 10 minutes journaling, and finish with a Sudoku puzzle. Sketching, knitting, and learning to play an instrument are options, too.

2. Start with 10 to 15 minutes. Some TikTok creators spend 45 minutes or longer working through their stacks, but you don't have to follow their lead. Start small and add more time when your schedule allows.

3. Keep your brain stack within reach. Place your book, journal, and puzzle near your bed, desk, or favorite reading spot. (Or better yet, keep them all in your analog bag!) Making these activities easy to access means you won't have to search for something to do when you feel the urge to pick up your phone.

4. Give your phone a little distance. Put it on silent, turn off non-essential notifications, or leave it in another room while you work through your stack. This helps you avoid the temptation to check every notification or switch back to TikTok halfway through once you feel your mind wandering.

5. Don't turn it into another productivity challenge. Your brain stack doesn't have to look the same every day. On busy mornings, you might only have time to read a few pages. On slower evenings, you can spend longer journaling or working on a puzzle. The point is to make space for activities you enjoy, not give yourself another reason to feel guilty about how you spend your time.
