Matt and Dr. Eti Ben Simon join forces once again to answer all of your top sleep questions. This time around, they break down the science behind the snooze button, why you might be falling asleep during passive activities like watching TV, and the truth about sleep fads like consuming salt before bed or using "grounding sheets." The episode also explores the frustrating issue of sleep fragmentation - waking up multiple times a night - and why it undermines sleep quality even if you fall back asleep quickly.

Learn how to assess your own sleep quality using key daytime indicators like energy and mood, without needing a tracker. For those struggling with frequent awakenings, discover a powerful, science-backed strategy called "bedtime restructuring" to help consolidate your sleep. The episode concludes with a look at new research on a potential "fail-safe" for sleep induction linked to mitochondrial stress, revealing a new frontier in sleep science.
