The Ideal Length of Time for Focused Work | Dr. Andrew Huberman
Huberman Lab Clips・2 minutes read
Our brain and body operate in 90-minute cycles, making it ideal for tasks like physical exercise, skill learning, or focused work. Setting a timer for 90-minute focused work sessions, followed by deliberate defocusing for 10-30 minutes, is crucial for maintaining productivity and mental energy.
Insights
- Our brain and body function in 90-minute cycles, ideal for tasks like exercise, learning, or work, with a transition period at the start.
- Setting a 90-minute timer for focused work, understanding the brain's metabolic energy consumption, and taking deliberate defocusing breaks of 10-30 minutes post-session are crucial for maintaining productivity and mental well-being.

Recent questions
How long should I focus on mental tasks?
The ideal duration for focusing on mental tasks is around 90 minutes, as our brain and body operate within 90-minute ultradian cycles. Setting a timer for this duration is recommended, with occasional focus flickers being normal.
Why is deliberate defocus important after a focus session?
Deliberate defocus, taking at least 10-30 minutes after a focus session, is essential for mental decompression. Engaging in menial tasks or avoiding phone use during this time aids in restoring the mind, crucial for subsequent focus sessions.
What is the purpose of the transition period at the start of tasks?
The transition period at the start of tasks is crucial as our brain consumes significant metabolic energy during focus. Understanding this transition period helps in preparing for focused mental work or learning.
How does deliberate decompression aid in maintaining focus?
Deliberate decompression, similar to rest between exercise sets, is vital for maintaining focus. This period allows the mind to idle and restore, with sleep being the ultimate form of restoration post-focus bouts.
Why is it recommended to focus on tasks in 90-minute cycles?
Focusing on tasks in 90-minute cycles is recommended because our brain and body operate within 90-minute ultradian cycles, distinct from the 24-hour circadian cycles. This duration is ideal for tasks like physical exercise, skill learning, or conversation, with a transition period at the start.

Optimal Focus: 90-Minute Cycles for Productivity
- Our brain and body operate within 90-minute ultradian cycles, distinct from the 24-hour circadian cycles. When focusing on tasks like physical exercise, skill learning, or conversation, the ideal duration is around 90 minutes, acknowledging a transition period at the start.
- Setting a timer for 90 minutes for focused mental work or learning is recommended, with occasional focus flickers being normal. It's crucial to actively refocus and understand that the brain consumes significant metabolic energy during focus.
- After a focus session, taking at least 10-30 minutes for deliberate defocus is essential. Engaging in menial tasks or avoiding phone use during this time aids in mental decompression, crucial for subsequent focus sessions.
- Deliberate decompression, akin to rest between exercise sets, is vital for maintaining focus. This period allows the mind to idle and restore, with sleep being the ultimate form of restoration post-focus bouts.
