What Happens in the Shower That Boosts Creativity? I still remember the eureka moment that changed my perspective on creativity. Standing under the showerhead, I felt the warmth of the water wash away my mental blocks, revealing a solution to a problem that had stumped me for weeks. It wasn’t an isolated incident; countless others have reported similar experiences. So, what’s happening in the shower that sparks these creative breakthroughs?
Now we’re beginning to understand why these clever thoughts occur during more passive activities and what’s happening in the brain, says Christoff. According to the latest research, a specific pattern of brain activity—within the default mode network—is the key, and it occurs when an individual rests or performs habitual tasks that don’t require much attention.
Researchers have shown that the default mode network (DMN)—which connects more than a dozen regions of the brain—becomes more active during mind-wandering or passive tasks than when you’re doing something that demands focus. Roger Beaty, a cognitive neuroscientist and lab director at Penn State University, describes the DMN as the brain’s go-to state when it’s in a passive mode. By contrast, the brain’s executive control systems actively focus your thinking, making it analytical and logical when you’re tackling a demanding task.
A cautionary note: While the default mode network plays a key role in the creative process, “it’s not the only important network,” Beaty says. “Other networks come into play as far as modifying, rejecting, or implementing ideas.” So it’s unwise to place blind faith in ideas that are generated in the shower or during any other bout of mind wandering.
What is the default mode network?
Marcus Raichle, a neurologist at the Washington University School of Medicine in St. Louis, and his colleagues serendipitously discovered the default mode network in 2001 when they were using positron emission tomography (PET) to see how the brains of volunteers were functioning as they performed novel, attention-demanding tasks. The team then compared those images to ones made while the brain was in a resting state and noticed that specific brain regions were more active during passive tasks than engaging ones.
However, because the function of each brain region isn’t well characterized and because a specific brain area can do different things under different circumstances, neuroscientists prefer to talk about “networks of brain areas,” such as the default mode network, which function together during certain activities, according to John Kounios, a cognitive neuroscientist and director of the Creativity Research Lab at Drexel University in Philadelphia.
Raichle named this network the “default” mode network because of its heightened activity during idle periods, says Randy L. Buckner, a neuroscientist at Harvard University. But it’s something of a misnomer because the default mode network is also active in other mental tasks, such as remembering past events or engaging in self-reflective thought.
Beaty explains that the network plays a crucial role in the early stages of idea generation, drawing on past experiences and worldly knowledge. “When you’re not actively working on a problem, the brain keeps spinning and you can get restructuring of elements of the problem, pieces get reshuffled, and something clicks.” The DMN, he adds, “helps you combine information in different ways and simulate possibilities.”
The level of creativity while in the shower
To investigate changes in brain activation and connectivity between different regions of the DMN, researchers asked volunteers to alternate between activities involving high cognitive effort (naming colors), low cognitive effort (reading words), and no cognitive effort (resting). They found that the default mode network was most active when the participants were at rest and more active during the low-effort task than the high-effort one, according to the study in the April 2022 issue of Scientific Reports. DMN activity can toggle up and down, like a dimmer, and researchers suggest that it adjusts to intermediate levels based on the cognitive challenge required.
Researchers demonstrated the link to creative thinking in a January study involving patients who underwent awake brain surgery, allowing surgeons to map language functions on the exposed cortical surface. Researchers applied direct electrical stimulation to patients’ default mode networks or other brain areas, then asked them to perform an alternate-uses task, inventing unusual uses for a paper clip to assess divergent thinking abilities. The researchers found that the patient’s ability to successfully perform the alternate-uses task depended on the strength of connections between nodes of the default mode network.
Conclusion
As we’ve explored the mysteries of shower-induced creativity, it’s clear that this everyday ritual offers a unique catalyst for innovation. By embracing relaxation, distraction, and the subconscious mind, we can tap into the shower’s transformative power. So, next time you step into the shower, remember to let your mind wander – you never know what brilliant ideas might flow forth.
