We even have ultradian rhythms within a day. This is why taking 20 minute breaks after 2hours of work is good for you. It clears your cache so you can process more. Try binaural beats or some deep breathing. You'll come back to the work bench inspired, or at the very least, refreshed.
Will try out those beats for sure

Never mind was a translation thing we just call it internal clock
