Time Perception & Entrainment by Dopamine, Serotonin & Hormones | Huberman Lab Podcast #46

TL;DR

Our perception of time is directly linked to neurochemical states controlled by molecules like dopamine and serotonin, which impact how fast or slow we perceive the passage of time.

Transcript

• Welcome to the Huberman Lab Podcast where we discuss science and science-based tools for everyday life. [bright guitar music] I'm Andrew Huberman and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. Today we are talking about time perception. Our perception of time is perhaps the most important factor in how we ga... Read More

Key Insights

• ⌛ Our perception of time is influenced by neurochemical states controlled by molecules like dopamine and serotonin.
• ⌛ Different neurotransmitters impact time perception differently, with dopamine causing overestimations and serotonin causing underestimations.
• ☠️ Arousal, dopamine levels, and blink rate are interconnected, with heightened arousal leading to increased blink rate and changes in time perception.

Questions & Answers

Q: How does our perception of time impact our daily lives?

Our perception of time is linked to our mood, stress levels, and overall well-being. It affects our ability to judge success, evaluate the future, and make decisions.

Q: How does dopamine impact our perception of time?

Dopamine leads to overestimations of time, making events feel longer than they actually are. It fine-slices time, increasing the frame rate of our perception.

Q: How can we enhance our perception of time?

By understanding how dopamine and serotonin impact our perception, we can adjust our activities accordingly. Engaging in tasks that require precision and adherence to rules in the morning can align with higher dopamine levels. Engaging in creative and flexible tasks in the afternoon aligns with higher serotonin levels.

Q: How does cold exposure impact time perception?

Cold exposure increases dopamine levels, leading to the perception of time passing more slowly. This can be leveraged by finding distraction or focusing on external cues to divert attention from the experience.

Summary & Key Takeaways

• Our perception of time is directly linked to neurochemical states that control mood, stress, and happiness.

• Entrainment is the process of matching our internal processes to external events. We are entrained to circannual, circadian, and ultradian rhythms that dictate our perception of time.

• Dopamine and norepinephrine fine-slice time and lead to overestimations of time, while serotonin causes underestimation.

• Arousal, dopamine levels, and blink rate are interconnected, with heightened arousal leading to increased blink rate and changes in time perception.
