Ask Me Anything Part 22: Latitude, Pain Gating, Temperature & Shift Work


Listen Later

In this latest AMA instalment, Matt and Dr. Eti Ben Simon begin by discussing environmental influences on sleep. The conversation covers how high latitude and prolonged daylight disrupt circadian rhythms, with Eti sharing her own personal experience. Together, our duo shares strategies for managing light exposure and regulating core body temperature with methods like warm baths. The episode also offers evidence-based approaches for shift workers, including strategic napping and forward-rotating schedules.

The discussion then shifts to internal mechanisms, debunking the "sleep before midnight" myth and emphasizing alignment with one's chronotype. The role of the thalamus as a sensory gate for blocking pain during sleep is detailed, with Eti noting that meaningful stimuli can still break through this barrier. Finally, the use of Gabapentin is examined, outlining its limited efficacy for primary insomnia versus conditions like restless legs syndrome.
