Time Perception & Entrainment by Dopamine, Serotonin & Hormones | Episode 46

Main Takeaways

  1. Entrainment refers to the way our internal processes are linked to the external world, particularly through light processing by nerve cells.
  1. Light is a powerful modulator of melatonin and affects our hormones, energy levels, and perception of time.
  1. Our bodies are tied to sunlight and the environment, and disruptions in circadian entrainment can lead to poor health outcomes.
  1. To realign our circadian clock, we should get sunlight in the morning, limit light exposure in the evening, exercise and eat at consistent times.
  1. Sleep is governed by the 90-minute ultradian rhythm that impacts our focus, brain cycles, and productivity.
  1. Dopamine and serotonin modulate perception of time, and their levels vary throughout the day.
  1. The more dopamine and epinephrine released, the more we overestimate how much time has passed, and the opposite is true for serotonin.
  1. Trauma or traumatic events can lead to "overclocking," where we perceive things in slow motion, and trauma treatment aims to slow down the frame rate.
  1. Our perception of time can be controlled through spontaneous blinking, cold exposure, and novel experiences with people or places.
