Andrew Huberman Focus Protocols

Neuroscience finding that spending 30-60 seconds staring at a specific point before deep work narrows the visual field and triggers norepinephrine release, priming the brain for focused cognitive effort.

Productivity application built on neuroscience research demonstrating why 90-minute focus sessions optimize cognitive performance, offering structured time blocking based on scientific principles of attention and mental energy management.

Caveday's research-based sprint length of 45-52 minutes, optimized for the brain's natural focus capacity and aligned with ultradian rhythms, providing an alternative to the traditional 25-minute Pomodoro that better suits deep work sessions.

A book by Cal Newport that argues cultivating the ability to focus without distraction on cognitively demanding tasks is one of the most valuable skills in the modern knowledge economy. Newport provides a rigorous training regimen for developing deep work habits.

Natural biological rhythm discovered by sleep researcher Nathaniel Kleitman involving 90-120 minute cycles of high-frequency brain activity followed by 20-minute recovery periods, present during both sleep and waking hours, forming the scientific foundation for productivity techniques like ultradian rhythm scheduling.

Extended Pomodoro-style technique using 50-minute focused work sessions followed by 10-minute breaks, designed to allow deeper flow states while maintaining the productive work-to-rest ratio.
