Matt and Dr. Eti Ben Simon team up to answer more audience questions today, and begin by delving into the subjective experience of time during dreams, exploring how our perception stretches and compresses during REM sleep and whether we can hack our dreams. They also explain the cognitive, emotional, hormonal, and immunological consequences of pulling an all-nighter, highlighting the dramatic impact on memory consolidation, stress hormones, appetite regulation, and immune function. The cardiovascular and metabolic repercussions are also addressed underscoring the serious health risks associated with chronic sleep deprivation.

The discussion shifts to the societal bias favoring morning types, challenging the notion that evening types are simply lazy. Our hosts examine chronotypes, the “sentinel hypothesis”, and the importance of aligning sleep schedules with individual preferences for optimal health. Matt and Eti then draw the episode to a close by addressing the common phenomenon of night sweats, differentiating between pathological causes and the normal thermoregulatory disconnect during REM sleep.
