The “Nervous System” Workday

The majority of people plan their workday around deadlines, their calendar or if they are completely honest their caffeine levels. The nervous system, however, has its own schedule. This is something that is quietly dictating when your brain is in fact primed for deep focus, emotional steadiness and creativity. With smart rings such as Oura and Ultrahuman, it is finally possible to see that type of schedule rather than guessing. The result of this is a workday that is built according to biology rather than obligation. 

At the very heart of this idea is vagal tone. This is a measure of just how flexible and resilient your parasympathetic nervous system is. In general, high vagal tone means you are calm but alert, physiologically stable, and mentally capable of making a sustained cognitive effort. In other words: the perfect state in which to write something difficult, original, or highstake.

Why your brain works better at certain hours

Over the course of the day, the nervous system cycles through predictable patterns. In the morning cortisol rises to wake you up. Your heart rate variability (HRV) fluctuates as a result of stress and recovery, and your prefrontal cortex, the bit of the brain that is responsible for language, planning, and creativity, follows its own rhythm. When vagal tone is high, HRV is usually high as well. This signals that your system is balanced and therefore ready for complex thinking.

This is why there are some hours that feel like magic and others that unfortunately feel like you are typing through mud. It is not something that you are imagining, but something in your biology. 

How smart rings reveal your peak cognitive window

Both Oura and Ultrahuman track a number of functions. These include HRV, resting heart rate, sleep stages, and recovery. Inside those metrics our personal “creative zone” is hidden. These are the hours when your nervous system is most able to undertakedeep work.

It isn’t as hard to find as you might think. To start you need to check your recovery score, or morning readiness – a high score usually correlates to a longer window of high vagal tone. Then you should look at your HRV trend across a day, for many people the peak is mid-morning or early afternoon, however this is an individual thing. The points where your ring shows steadier heart rates or lower stress will tend to be your best working hours. 

It is important to track your own output as well, consider your data with subjective notes. For example, when did your writing feel fluid? When did ideas come more easily to you?

Once you have done this for a couple of weeks you will see a pattern of recurring blocks of 60-120 minutes where your nervous system will consistently support deep focus.

Building a “Nervous System Workday”

Once you have discovered your peak vagaltone window, you should protect it. This is where you should do your more complex writing, strategy documents, creative drafts, emotionally demanding emails,  those items that require nuance or originality. Use time outside this window to schedule meetings, admin, and shallow tasks.

This is not productivity hacking, but nervous system alignment. When you work with your biology rather than against it, writing will no longer feel like a battle. It will begin to feel like something that flows.
