Everyone experiences tiredness at work sometimes. At some point (usually around 2:00 PM), you find yourself ready for a nap. Your energy fluctuates naturally throughout the day.
Productivity expert Chris Bailey charted his motivation, focus, and energy levels for 21 days and found that all three tend to spike between 7:00 and 8:00 AM, 11:00 AM and 12:00 PM, and 6:00 and 7:00 PM.[1] For all those highs, he also noticed times when focus, energy, and motivation were nowhere to be found. Chris was tired at work.
Your peak productivity times may be different than Mr. Bailey’s, but the overall shape of your energetic graph would still look like a series of zigzags. The amount of sleep you have, the food you eat, and how you exercise are a few of the factors that cause rises and falls in your energy level.
You’re battling your biology when you don’t take a nap
We can fill up on caffeine and sugar as much as we want, but we’re fighting a natural downturn in energy when we do this. Most people feel fatigued in the latter half of the standard workday. Your tiredness may seem like an inconvenience, but it’s really your body telling you that it needs rest.
Our bodies operate on a natural clock called a circadian rhythm.[2] This sleep/wake cycle is perfectly adapted to give us adequate sleep over the course of a 24-hour period. Natural light is the primary means that your body uses to assess whether or not you should be asleep.
Much to our collective chagrin, circadian rhythms do not coincide with the average 9 to 5 job. Irregular sleep schedules, the light from electronic devices, and natural light exposure can also affect the cycle. This is why people working the graveyard shift have an increased risk for developing health problems.[3] They must remain awake when their body tells them it’s time for bed, and their sleep schedule is constantly disrupted when they try to stay awake on days off.
Neglecting to follow your circadian rhythms and not taking a nap go against your body’s natural balance.
Taking a nap is natural
We usually feel the most tired between 1:00 PM and 3:00 PM. This is the post-lunch crash that most of us try to fend off with sugary snacks or espressos. We’re also naturally more inclined to sleep between 2:00 AM and 4:00 AM, which is why waking someone up during that time can feel like raising the dead.
Since most of us are already asleep between 2:00 AM and 4:00 AM, we need only concern ourselves with the post-lunch crash. Taking a nap right after lunch helps most people feel more alert, energized, and motivated.
Why you should squeeze a nap into your day
Taking a nap can replenish your brainpower and leave you feeling just as sharp as you were first thing in the morning. You can’t change the fact that your body operates on a circadian rhythm and your energy level rises and falls, but you can pay attention to what your body tells you to do. If you want to feel energized, you need to recharge.
When you don’t take a nap, you struggle against your body’s need for sleep. You may look busy while you’re sitting at your desk, but the simplest tasks will take you much longer to complete. You’ll have a harder time making decisions, and you’ll likely feel a bit grumpy.
Taking a nap may put you out of commission for 20 minutes, but you’ll be refreshed when you wake up. You’ll be able to do more work in a shorter amount of time, and you’ll probably have a better outlook on the rest of your day. That nap is the reset button that you need to do your best work.
You can reap amazing benefits from taking a 15-20 minute nap.[4] Longer naps put you into different phases of your sleep cycle, and if those are disrupted, you might end up feeling more tired. A nap of 20 minutes is all you need.
The catnap is a low-cost energy booster. It requires so little energy and effort to give yourself this time to refuel, and the return on investment is huge. Some studies suggest that a 20-minute nap has the energy-boosting equivalent of more than 200 mg of caffeine, or two cups of regular coffee (minus the jitters). A power-nap has the potential to add an extra three hours of productivity to your day.
My napping experience at work for the last 2 weeks
Just to be clear, I’m not advocating that you bring your sleeping bag and grab a little shuteye anytime you feel lethargic. That’s definitely not going to go over well with your boss. You won’t be napping the entire afternoon away on the clock. You just need to take a 20 minute break after lunch to do what I’ve been doing.
For the last two weeks, I’ve been taking 20-minute naps in my office after lunch. I silence my email notifications and set an alarm so that I wake up at the end of the 20-minute window. I put in my ear buds and listen to this relaxing playlist. I rest on the couch with a small cushion that I keep stashed in my desk.
At first it felt weird to be taking a nap at the office. It took me about 5 minutes to fall asleep the first few days because I wasn’t used to unplugging in the middle of the day. After a few days, though, I was able to fall asleep soon after I started listening to the relaxing playlist.
Within the first few days of conducting this little experiment on myself, I felt a big difference. After I woke up from my naps, I felt so much more energized. I could concentrate, and I was able to work all the way up until the end of the day instead of watching the clock in anticipation of closing time.
After just one week, I found that my productivity had dramatically improved. I used to feel so inefficient after lunch, but when I implemented the short post-lunch nap, I felt as energetic as I do in the morning. My energy seems to be more evenly distributed throughout the day, and I can be productive for longer.
Give power-napping a try
It may seem counterproductive to take a nap in order to do more, but there’s science behind the catnap. Instead of staring off into space and battling your natural fatigue, take a nap. You may think that you’ll lose 20 minutes of work, but the increased energy and focus you experience after your nap will more than make up for it.
