Neuroscience has shed some light on daydreaming or letting the mind wander. Humans spend up to half of their waking hours daydreaming. The ‘decoupling hypothesis’ proposes that when we daydream, brain resources are shifted away from our external environment to our internal environment.1
Our minds often wander during routine, mundane tasks, such as walking the dog or taking a shower. We can still interact with things around us when we daydream because our brain can interrupt these thoughts to give direction, especially if the brain perceives danger or a threat.
What if we suspend disbelief and decide that spending time daydreaming is important? What is obscene wealth if you don’t have time? What is good health if you don’t have time to enjoy your body and existence?
People of any age may remember when someone else told them to ‘get their head out of the clouds’ or some other criticism. Most of us have been scolded while daydreaming-especially when we were younger. Some studies found that in adulthood, mind-wandering was equated with unhappiness because we spent time thinking about negative issues and problems in our lives.2
Daydreaming at work has been positively linked with innovation in the workplace, especially when we use it as a tool to tackle complex problems and challenges. Organisations that want to promote innovation should embrace science and create work environments that encourage daydreaming.3
A recent study4 found that daydreaming should become part of the cognitive toolkit and that many of us do not know how to daydream successfully. The idea of thinking for pleasure may sound odd or even boring. Many of us need to train our brains to daydream properly. Essentially, our imaginations are often unable to use this time for good.
Thinking for pleasure is difficult, especially when we feel pressure and stress from everything around us. Researchers coached a group of volunteers to think ‘meaningful thoughts’, but the volunteers had difficulty doing so. When unguided, people didn’t get much satisfaction from spending the time daydreaming, and when prompted, the research subjects still did not find deep meaning to their thoughts.
Finally, participants were given topics they considered both meaningful and pleasant, and they reported their daydreams to be 50% more enjoyable than when they were allowed to think about anything. Even though these results were promising, the scientists acknowledged the difficulty of daydreaming. It is a skill that can increase our happiness and help us reconstruct our emotions, which is a powerful tool in times of stress.
It is estimated that we spend about half of our lives thinking about something other than what we are doing, and research has shown that parts of our brain ‘fall asleep’ when this occurs. Known as local sleep intrusions, scientists believe these moments may explain attentional lapses, impulsivity, and suddenly going blank and forgetting what we were doing.
These lapses may occur more frequently if we are sleep-deprived, and neurons in the brain behave similarly to sleep during these moments. Being tired means we have more difficulty controlling our attention, resulting in decreased performance and fewer opportunities for innovation.
In a recent study5, scientists asked volunteers to complete repetitive, monotonous tasks. The volunteers were asked randomly while completing the task to report their thoughts. They could indicate they were focused on the task, their mind was wandering, or their mind was blank. An electroencephalogram was used during the span of the test.
Researchers focused on ‘slow waves’ because they are indicative of sleep, showing a lapse in neuronal activity. Slow waves occurring at the front of the brain led to impulsiveness, and volunteers reported that their minds were wandering. Slow waves occurring at the back of the brain were related to the mind being blank and sluggish.
The volunteers in the study were young and healthy and had not reported being tired or sleep-deprived. Scientists found the slow waves did correspond to moments of either wandering or blankness. During the experiment, the volunteers worked on repetitive tasks, completely unaware that their brains were going on and offline the whole time.
As children, it seems like things can never come fast enough—the end of school, birthdays, and other celebrations. As an adult, it suddenly seems like we never have enough time to get everything done. We rush frantically from one thing to the next until we get sick or burn out. This isn’t anything to be proud of! We should recognise the sadness here and lament the loss of all those good ideas, daydreams and innovations.
Thinking about the enormity of time is difficult for our brains. Our lives are so short compared to the universe's age, which is estimated to be around 13.8 billion years old.6 80 or 100 human years is nothing compared to the endless grind of time around us. Why, if we are given so little, don’t we do more with it?
Time is the most valuable thing a man can spend.

But what about daydreaming? Isn’t that a colossal waste of this precious time? No! Science has proven that daydreaming is beneficial. When we let our brains wander, we improve how we solve problems. Isn’t that something a leader should want to improve?
It is important to remember that businesses and companies do not innovate--the people who work for them do.
Innovation does not always come in a split second, but we must consider this time a worthy investment. Employees are already taxed for time, so when we expect quick returns, we will often be disappointed in the long run.
Some leaders may be wary of giving this time to their employees, fearing the time will be squandered or misused. However, this kind of micromanaging will typically stifle innovation altogether. If we cannot trust those we work with, why are they there?
When things start to seem stale, try actively finding time to think about nothing. Find a spot where you can relax and then really DO relax. Stop worrying, stop planning your next move, and stop mentally writing emails. Just give your brain and imagination some time alone. You almost want to step out of your mind and look in, if you can picture that.
Contrary to what most people believe, innovation doesn’t always come quickly. Sometimes we need to work at it--by not really thinking about it. It sounds like an oxymoron, but if we indulge ourselves and allow daydreaming, we’ll allow new ideas to surface. How many ideas are potentially being missed?
