Stop Feeling Tired Already

by | Sep 25, 2017

World-class research explains how to work around your fatigue.


We all are.

Your daily energy, of course, is finite, dwindling by the minute.

So make those minutes count. Fatigue management starts with time management:

Enter: Daniel Kahneman

Kahneman, a psychologist and Nobel winner, conducted a study that applies to every working person in the world.

The study evaluated how people felt throughout the day (e.g., happy, sad, worried, competent, fatigued) and whether those feelings correlated with a specific time of day. About 900 people participated in the study, recording how they felt over the course of several workdays.

According to Kahneman’s data:

  1. People feel most energetic and competent in the morning, after sleeping 7 – 8 hours
  2. People feel most rejuvenated after napping for 20 – 30 minutes

That’s the data. But what’s the practical application?

Enter: Anders Ericsson

Ericsson, renowned for his work on the nature of expertise and human performance, studied the best violinists in the world. Specifically, he analyzed their routines to better understand what enabled their success.

Not surprisingly, his research correlated with Kahneman’s data. For example, the violinists:

  • Practiced first thing in the morning, when they felt their most energetic
  • Napped every afternoon, when they felt their most fatigued

Furthermore, the musicians reported that rest—light naps during the day and deep sleep at night—were “most important” to gradually improving their performance.

Ericsson also observed that violinists practiced for 90-minutes at a time. Then, at the end of each interval, they took a break. But why?

Enter: Nathaniel Kleitman

Kleitman, a pioneering sleep researcher, demonstrated that your brain can optimally focus on a task for only 90 minutes before becoming distracted (courtesy of your ultradian rhythm, a cycle of brain waves that are present during the day and at night).

In other words, the same 90-minute cycles we progress through in our sleep are also present in our waking lives.

Ultradian Rhythm

There’s no getting around this, of course, no gaming the system.

It’s built into our genome: Activity, rest. Activity, rest.

Stop being tired already.

According to the research, it’s not all that hard.

But, like most goals, you need an action plan to achieve success.

Start here:

1. Do your hardest work before noon.

Kahneman taught us that self-confidence and energy levels are highest in the morning.

Capitalize on this by getting up earlier and starting sooner, while you’re clear. Energy levels start dropping around noon, or so.

2. Break every 90 minutes.

Kleitman taught us that consistent breaks reset us, making it easier to organize our thoughts, solve problems, internalize new concepts, and ultimately, focus.

Capitalize on this by actually taking breaks. Don’t overthink this.

Leave your desk and forget about your work for 15 minutes: Let your thoughts incubate. After you walk away from a problem, your brain is still working to solve it in the background.

Live cyclically.

Activity, rest.

Activity, rest.

3. If you’re tired in the afternoon, nap for 20-30 minutes.

Ericsson taught us that napping is normal, healthy human behavior. After all, the most talented musicians in the world take daily naps.

If you can’t nap, try meditating.

The point here is to not feel weird about it. Don’t feel guilty or weak or immature. Napping is restorative, completely normal. And you’re normal if you do it.

Manage your fatigue.

A few simple hacks, repeated consistently, is all it takes.
