In this Huberman Lab Essentials episode, I explore how biological rhythms and neurochemicals impact our perception of time.

I describe how the body aligns with daily and seasonal light cycles to regulate hormones that influence energy, mood and motivation throughout the year. I share science-based tools to enhance focus and productivity, including strategies for structuring work intervals and optimizing the timing of exercise and daily light exposure. I also explain how neurotransmitters like dopamine and serotonin influence our perception of time and how factors such as novelty, emotion and routine impact how we experience and recall time.
