This is grasping at straws, we need EXACT DEFINED PREVENTION PROTOCOLS; not some meme.
How often do you stop to think about your pinky fingers? Probably not much. How often do you actually exercise them? Probably less than not much. Maybe it’s time to give that a try, though. According to TikTok, working those baby digits could benefit your brain in a big way.
The “Pinky Time Exercise” is a finger movement workout in which you simply wrap your middle and pointer fingers together, touch your ring fingers and thumbs together, and move your pinkies up and down. You can practice pinky time anytime, anywhere.
It’s claimed on many social accounts that just 10 seconds of pinky time can boost your brain’s plasticity, reducing your Alzheimer’s odds. Consistency is supposed to be key to getting the best results, which really can be a good thing: research has shown that regular finger exercise can improve circulation in the brain, leading to better memory, thinking, and understanding. The same research pointed out that finger exercise in general also activates cerebral cortex function, which can slow down cognitive decline.
So, can pinky time specifically protect you from developing Alzheimer’s completely, though? Let’s take a closer look—and cover ways to maximize its good effects.
How the pinky exercise helps with brain function
It starts with the fact that you’ve probably never done it before. “Broadly speaking, learning something new can stimulate the brain,” says Richard B. Lipton, M.D., professor of neurology and vice chair of neurology at Montefiore Einstein in Bronx, NY. “Both physical activity and mental stimulation boost levels of brain‑derived neurotrophic factor (BDNF), a chemical that stimulates brain cells to form new connections, or synapses. This, in turn, may promote successful brain aging and prevent dementia.”
Pinky time might, then, have a surprisingly significant impact on your brain. “It may seem like a simple task, but pinky time actually can help to strengthen your brain,” says Michelle DiBlasi, D.O., chief of inpatient psychiatry at Tufts Medical Center in Boston. “Your brain can continue to grow and develop even when you become an adult, and can be challenged to adapt and develop new neuronal pathways. Whenever your brain is put into situations where it has to focus on a new pattern or expanding its ability to improve coordination, this actually helps it to develop those new pathways.”
The repetition required to perform pinky time also plays an important role. A 2025 study from the University of Pennsylvania School of Nursing found that repeating finger exercise may improve cognitive performance through hand-brain coordination; this may enhance attention, memory, and executive function.
The exercise also requires concentration, which can sharpen how well your brain works. Pinky time requires that you move your fingers in complex ways on both hands at the same time,” says Dr. DiBlasi. “When you do this, you’re helping both sides of your brain to communicate with one another, which deepens the connection between the left and right sides of your brain.”
Can pinky time actually cut your risk of cognitive disease?
The jury is definitely out on that for now. It could have some beneficial effects when it comes to staving off disease down the line—a 2026 study found that hand exercises can enhance motor and functional abilities in patients with mild cognitive impairment (MCI), a condition that’s a precursor to dementia. But there’s no proof at the moment to show that pinky time
specifically could slow or prevent Alzheimer’s or any other cognitive illness. There’s also no research that identifies an exact amount of time you’d need to do pinky time per session to gain that kind of benefit.
“We don’t have enough evidence to show that pinky time has the strength to prevent Alzheimer's,” Dr. DiBlasi says. “However, I do think that this trend is important. Pinky time reminds people that there are ways we can help to prevent Alzheimer's and cognitive decline.”
Dr. DiBlasi suggests that in addition to enjoying the benefits of pinky time, you can potentially lower your Alzheimer’s odds by picking up a hobby that further speeds processing in your brain.
You can try:
- Learning a new language
- Learning how to play a musical instrument
- Taking up table tennis (Marty Supreme was on to something!)
- Teaching yourself how to juggle
Still, the best trick for keeping your brain healthy is to adopt a healthy lifestyle, Dr. DiBlasi stresses. “Eating a healthy diet, exercising regularly, staying social, and being mentally engaged on a daily basis are also key to preventing worsening cognition. Here are some easy ways to ace that brain-healthy lifestyle:
- Eat more fatty fish, leafy greens, berries, and walnuts, and drink tea and coffee. These are brainpower superfoods, according to Harvard Medical School.
- Try a moderate-intensity workout like brisk walking for about 150 minutes a week, or three to four times a week.
- Plan face-to-face activities with friends and family every week, and call or FaceTime them when you can’t be together.
- When you’re focusing on something, really focus on it. Absorb every detail of that true crime podcast you love, and try to first solve the mystery yourself; challenge yourself with the hardest crossword puzzle you can find every morning.
The bottom line
We can’t be 100% sure yet that pinky time can prevent or slow the development of cognitive disease—but there is proof it can strengthen your brain. “Pinky time can’t hurt, but ideally should be part of a program that includes other proven approaches to promote successful brain aging,” Dr. Lipton sums up.
What we also know, having tried pinky time: it’s fun! Give it a whirl today, for as long as you like—then consider making it a regular habit.
