4 Key Concepts
Ultradian Rhythms
Ultradian rhythms are biological cycles that are shorter than 24 hours, typically referring to 90-minute cycles that govern sleep patterns and influence daytime alertness and focus. These cycles dictate periods of heightened cognitive ability and subsequent dips.
Neuroplasticity
Neuroplasticity is the brain's inherent ability to change and adapt in response to experience. This involves the formation of new connections between neurons, strengthening or weakening existing ones, which is the fundamental biological basis of all learning.
Glucocorticoid System
This system regulates the release of cortisol, a hormone essential for health. A natural rise in cortisol in the morning is associated with enhanced immune function, alertness, and the ability to focus, effectively triggering the onset of beneficial Ultradian cycles for learning.
Iterative Metaplasticity
This concept refers to the idea that the brain's capacity for focus and neuroplasticity itself can be improved through regular engagement. The more consistently one forces themselves to focus, the easier focusing becomes over time, keeping the neural circuits for focus 'warm'.
8 Questions Answered
Ultradian rhythms are biological cycles shorter than 24 hours, most commonly referring to 90-minute cycles that influence our states of alertness and focus throughout the day and also govern sleep stages.
You can leverage Ultradian rhythms by identifying your peak periods of mental alertness (typically one in the morning and one in the afternoon) and scheduling 90-minute focused work blocks during these times, aiming for about an hour of intense focus within each block.
Most people can sustainably perform one or two 90-minute focused work blocks per day, with three being exceptional and four being highly unusual, often requiring specific lifestyle adjustments.
No, it's generally beneficial to engage in these focused sessions daily, even on weekends, as regularly accessing focus circuits makes focusing easier over time.
You can identify the start of an optimal Ultradian cycle for learning by observing when you naturally experience your greatest state of mental and physical alertness in the morning after waking, and again in the mid to late afternoon.
Cortisol, a hormone, has a natural peak in the morning that is associated with enhanced immune function, alertness, and the ability to focus, effectively triggering the onset of these beneficial Ultradian cycles for learning.
The actual rewiring of neurons and the consolidation of learning primarily occur during states of rest, specifically during deep sleep and non-sleep deep rest (NSDR), rather than during the focused work block itself.
Yes, these 90-minute Ultradian work blocks are also ideal for triggering neuroplasticity to improve motor skills, athletic movements, or any physical skill that requires significant focus and cognitive demand.
10 Actionable Insights
1. Identify Peak Alertness
Observe your mental and physical energy peaks daily, especially between waking and noon, and again between noon and 6-7 p.m., to identify optimal learning times. This helps you align with your body’s natural Ultradian cycles and glucocorticoid fluctuations for enhanced focus.
2. Schedule Ultradian Focus Blocks
Once you identify your peak alertness (e.g., 9:30-10 a.m. for the morning, and mid-to-late afternoon for the second), start a 90-minute Ultradian learning cycle around that time. Aim for one or two such blocks per day, as these periods align with optimal neuroplasticity.
3. Minimize Focus Block Distractions
During your 90-minute focus blocks, turn off Wi-Fi connections and put your phone in another room or turn it off. This helps you break into and maintain a deep trench of focus, as distractions can easily pull you out.
4. Expect ~60 Min Intense Focus
Plan your 90-minute Ultradian work blocks assuming that the first 10-15 minutes are for mental warm-up, and you will get about one hour of intense, deep focus within that period. This sets realistic expectations for maximizing learning.
5. Maintain Daily Focus Practice
Engage in focused learning bouts every day, including weekends, even if it’s less cognitively demanding like reading a book. Regularly accessing focus circuits keeps them ‘warm’ and makes focusing easier over time due to neuroplasticity.
6. Enhance Morning Cortisol Peak
Get sunlight in your eyes as close to waking as possible to enhance or increase the peak level of cortisol experienced early in the day. This sets in motion a number of Ultradian cycles, improving alertness and ability to focus.
7. Leverage Rest for Learning
Incorporate deep sleep and Non-Sleep Deep Rest (NSDR) into your routine. The actual rewiring of neurons and learning consolidation occurs during these rest states, which can accelerate learning.
8. Shift Cortisol for Third Block
To capture an additional early morning Ultradian work block (e.g., 6-7:30 a.m.), wake up earlier (e.g., 5:30 a.m.), use stimulants like caffeine and hydration, and engage in brief high-intensity exercise (10-15 minutes). This can shift the cortisol pulse earlier, creating an extra productive focus period.
9. Adjust Sleep for Early Waking
If you consistently force yourself to wake up earlier to gain an extra focus block, ensure you also try to get to sleep earlier. This is crucial because both the quality and duration of sleep are vital for learning and neuroplasticity.
10. Apply to Physical Skill Learning
Utilize these 90-minute Ultradian work blocks for physical skill learning, such as dance or athletic moves, that require significant focus and alignment of muscular movement. These periods are ideal for triggering neuroplasticity in the motor skill-based domain.

The more you force yourself to focus, the easier focusing gets.

The actual rewiring of neurons does not occur during any focused work block. It actually occurs during deep sleep the following night and the following night and during non-sleep deep rest.

2 Protocols
Leveraging Ultradian Rhythms for Focused Learning
Andrew Huberman- Observe your natural peak levels of physical and mental energy in the morning (between waking and noon) and again in the afternoon (between noon and 6-7 PM).
- Identify the approximate start time of your morning peak (e.g., 9:30 AM or 10 AM).
- At your identified peak time, set a stopwatch for a 90-minute focused work block.
- During this 90-minute block, eliminate all distractions (e.g., turn off Wi-Fi, put phone in another room).
- Assume the first 10-15 minutes will be a 'mental warm-up' before deep focus, and aim for about one hour of intense learning within the block.
- Capture a second 90-minute Ultradian learning block in the afternoon, following the same principles.
Shifting Cortisol to Achieve a Third Morning Ultradian Block
Andrew Huberman- Consistently wake up earlier (e.g., 5:30 AM).
- Immediately expose yourself to bright artificial light if the sun is not out, or sunlight if available.
- Engage in brief high-intensity exercise (e.g., 10-15 minutes of skipping rope, jumping jacks, or a brief jog).
- This routine can shift your cortisol pulse earlier, allowing you to capture an additional focused work block (e.g., between 6 AM and 7:30 AM) in addition to your later morning and afternoon blocks.
- Ensure you adjust your sleep schedule to go to bed earlier to maintain sufficient sleep duration.
