Why do the best ideas often come in the shower?

Taking a shower often creates the perfect conditions to unleash your inner genius. Here's why great ideas often come in the shower .

You're in the shower , mindlessly scrubbing your toes, when—boom!—a prophetic thought pops into your head. Maybe you finally solve that headache-inducing incident at work. Or maybe you learn something more important. Maybe the meaning of life. Or what the 23 flavors of Dr. Pepper are.

Those aha! moments aren't locked away in a bottle of Irish-scented shampoo. But soaking in the suds has a lot to do with it. Showering creates the perfect conditions for a creative moment, bringing out your inner genius. And it gets you clean, too.

Pay attention to meaningless work

Research shows that you're more likely to have a creative breakthrough when you're doing something monotonous, like fishing, exercising, or taking a shower. Since these routines don't require much thought, you'll go into "autopilot" mode. This frees up your subconscious to do other things. Your mind will wander, allowing your brain to quietly play a free-associative game, unhindered.

This type of daydreaming relaxes the prefrontal cortex—the brain's command center for decisions, goals, and behavior. It also activates the rest of the brain's "default mode network," clearing the pathways that connect different regions. When the cortex is relaxed and the default mode network is turned on, you can make new, creative connections that your conscious mind has overlooked.

That's why the ideas you have in the shower are so different from the ones you come up with at work—you're more closed off in the office. Thinking too hard about a problem deactivates the default network. It taps into the prefrontal cortex's ability to control itself. This isn't a bad thing—it gives you more focus and the strength to stop staring at cat pictures and finish your work on time. But it can also get you into a creative rut. Because when you're deeply focused on a task, your brain is more likely to censor unconventional—and creative—solutions.

It may sound strange, but your brain isn't at its most active when you're focused on a task. Instead, research shows that it's more active when you're relaxed and free. Shelley Carson at Harvard found that highly creative people share one wonderful trait—they're easily distracted. And that's the beauty of taking a warm shower. It distracts you. It lets your brain go wild. It triggers your 'default mode' and encourages weird ideas to pop up. So when the suds are gone, the idea 'light bulb' goes off.

Relax

But what makes the bathroom different from a boring board meeting? Doesn't your mind wander there?

You probably have the doodles to prove it. But showering is relaxing. It's a small, safe, enclosed space. You feel comfortable there. Best of all, you're probably alone. It might be the only private time you get all day. It's a chance to escape all the stressors of the outside world.

When you relax like this, your brain can release everyone's favorite happy, carefree neurotransmitter, dopamine. A surge of dopamine can fuel creative energy. You'll also see more alpha waves flooding your brain—the same kind that occur when you're meditating or happily relaxing. Alpha waves are associated with the brain's default daydreaming setting and can stimulate creativity.
