After a winter of discontent, I’m back on the bike. Commuting through woodland on sleepy backroads to and from work. Fitness, fresh air, petrol consumption down, yada yada. Honestly, that stuff is a given. What surprised me was the realisation of what cycling those precious 10 minutes per day does to my brain.
When I’m in the car I have to focus quite intently. I’m listening to the radio, but even when I’m on those same backroads most of my brainpower remains on steering, speed control and keeping concentrated. As you’d expect, right? When I’m on the bike I found that I can phase out. The bike steers itself, speed is a non-issue. I can take in the forest noises, look out for deer. And think. When I’m pedalling to and fro, my brain is processing stuff. It unpacks the day, it shuffles up random memories, it role-plays and pretends.
My brain needs process time. At times it has felt like grad school has dulled me. My imagination quietened, I struggled to stay on task and remain sharp throughout the day. Some of that is just the monotony of a long project with lots of in-built repetition.
But there’s also the reality that I can wake up in the morning, spend some time drinking Nespresso coffee and pouring over my diary. Then I’m at the gym or work. Then I’m coming home between 8 and 9pm and knocking up dinner. Maybe I’ll pull out a book or flick on the radio for a specific NPR program, but at this stage I’m usually running a bath and readying for bed. There’s a lot of action in my day, but there’s nothing that fosters brain processing. Scientists describe sleep (the dreaming phases) as being important for cognitive housekeeping: I suspect that we need some of that time when we’re awake, too.
The cycling helps. Exercise makes you feel more alert, but getting on a bike during the week is doing more for me than the gym could.
