Understand & Improve Memory Using Science-Based Tools | Huberman Lab Essentials

Andrew Huberman

Apr 16, 2026

Episode description

In this ⁠Huberman Lab Essentials⁠ episode, I explain how memories are formed and how key neurochemicals, such as adrenaline, can be leveraged to enhance memory formation. I also share science-based protocols to enhance learning, strengthen memory recall and reduce the number of repetitions needed to retain new information. In addition, I discuss how exercise supports cognitive function and memory and explore unique memory phenomena such as déjà vu.

Mindsip insights from this episode:

Capture mental snapshots to enhance memory retention

Intentionally deciding to take a 'mental snapshot' of a scene by blinking your eyelids can stamp down a more robust visual memory.

#memory

Understand deja vu through memory neuron activation

Deja vu is likely caused by the activation of neurons associated with a past memory, but in a different sequence or all at once, creating familiarity without a specific recall.

#cognition

Engage in load-bearing exercise to boost memory through bone health

Load-bearing exercise causes bones to release a hormone called osteocalcin, which travels to the brain to enhance memory and hippocampal function.

#memory

Practice daily meditation for memory enhancement after eight weeks

A brief, 13-minute daily meditation can enhance memory and attention, but only after consistently practicing for at least eight weeks.

#memory

Spike adrenaline to enhance memory retention

Memory enhancement comes from the sharp increase in adrenaline relative to your baseline, which is why being calm during learning and then spiking it is most effective.

Engage in 180-200 minutes of Zone 2 exercise to boost memory

A minimum of 180-200 minutes of Zone 2 cardiovascular exercise per week is thought to improve memory by promoting the creation of new neurons in the hippocampus.

#hippocampus

Spike adrenaline post-learning to enhance memory retention

To best improve memory, trigger an adrenaline release with a cold shower or caffeine immediately after a learning session, not before or during.

#memory

Leverage adrenaline spikes for memory enhancement techniques

In medieval times, children were thrown into rivers after witnessing important events to create a lifelong memory, unknowingly leveraging the power of an adrenaline spike.
