The metal thingy and the oldest advice in the world

It is summer, and it is vacation time. For me, like a million other house owners, that means the roof job I have postponed for years is finally being addressed.

When I rented the scaffolding it still sounded like a great idea. Even when I bought the paint, the timber and the things I don’t know the name of, the alarm inside my brain did not go off.

One week into the job I started questioning my mental health. Why on earth didn’t I call someone to do this for me? Someone who actually knows what they are doing.

And then I hit a wall. The metal thingy that protects the sides of the roof did not fit, and no youtube video on earth covers this situation. There was one obvious solution staring me in the face. It involved violent metal bending and bigger nails.

Just before I went for it, I stopped. It was getting late, and the effort needed to bend that metal would not be insignificant. Let’s tackle this tomorrow.

When I woke up the next day I started thinking about the problem waiting for me up there. And then: what if…? If the “what if” worked, I had just saved myself a thousand headaches, torn muscles and an ugly looking house.

I went straight out of bed, climbed the scaffolding and tried the theory in practice.

It worked. Hallelujah.

Now, what I came up with did not require a genius. My wife cracked the same problem in two seconds when I asked her what she would have done. But it demonstrated the power of the oldest advice in the world: sleep on it.

What my brain was doing while I wasn’t working

That old advice turns out to be, quite literally, science.

In 2004 a German research team published a study in Nature with the fitting title “Sleep inspires insight”. They trained people on a number puzzle that contained a hidden shortcut, a rule nobody was told about. Some slept, some stayed awake. After a night’s sleep, more than twice as many spotted the hidden rule.

The sleeping brain does not just file a days input away, it restructures it, it takes the problems you left behind and quietly rearranges the pieces into a new pattern.

And it is not only sleep. Psychologists call the wider effect incubation, and a meta-analysis of decades of experiments confirmed it is real: people solve problems better after a break than after grinding straight through. The interesting part is what kind of break works best: It’s undemanding activity, a walk with the dog, a swim or just staring at the sea.

Neuroscientists even have a name for what the brain switches to when we stop giving it tasks: the default mode network. It sounds like a screensaver but it behaves more like a dishwasher: you load it, press start, walk away, and the work happens even though you are not standing there watching it run.

Which brings me to your sun bed

You left something behind in June. We all did.

The stakeholder who will not take the meeting. The patient treatment access case that stalled in the committee. The account plan that looks right on paper and keeps not working in practice.

Here’s a reframe for your vacation-mode brain: you are not ignoring that problem right now. You are incubating it. The horizontal position, the slow days, the swim before lunch, this is not the opposite of working on it. According to the research, it may be the only thing your brain has not yet been allowed to do.

Permission to do nothing, granted, now with scientific backing!

How to help the machine along

A few things make the difference between incubation and forgetting.

Load the problem before you let it go. An empty dishwasher washes nothing. Write the problem down in one honest sentence, “I cannot get the cardiology clinic to care about our referral data”, and then close the notebook. The Nature study found sleep only produced insight in people who had engaged with the problem first.

Then let it go.

Keep a note within reach. Insights are volatile, they arrive in the shower, on the walk to the bakery, halfway up a scaffolding. Ten seconds on your phone note app will save them. Do not trust yourself to remember after the next umbrella drink.

Then test the idea on someone you trust and respect. My wife needed two seconds. Your colleague on their own sun bed might too.

The metal thingy, epilogue

It sits on the roof now. Straight, snug, no violence involved. Every time I look up at it I am reminded that the best move of that whole week was climbing down.

Somewhere in your head, a problem from June is being quietly bent into shape.

Let it.
