Dr. Noah St John says humans focus well for about 90 minutes before fatigue hits. Work in uninterrupted 90-minute blocks, then take a 5-10 minute break with movement or fresh air. This rhythm beats trying to push through longer stretches.
Hey Noah, what's the best trick for keeping your focus all day?
Oh, you know what the best trick for keeping your focus strong all day is? It's making sure you take breaks every 90 minutes. See, we humans are built for about 90 minutes of focused action, then we need a break. Have you ever noticed that after 90 minutes of work, your brain starts to get foggy? You know, you get sleepy, you get distracted. That's, that's okay. So the point is just work in 90-minute uninterrupted intervals. I call them NMUIs. And then take a break. Take about 5, 10 minutes, get up, go outside, walk around, just stretch your legs. Make sure that you then stay focused every day rather than trying to power through those things. It's a lot easier and it's a lot less stressful. You'll have a lot more fun.
