Sleep and Mortality
Hypersomnia can manifest in various ways, often linked to depression, where individuals may spend excessive time in bed without actually sleeping more. Research indicates a sweet spot of 7 to 9 hours of sleep for optimal health, as both insufficient and excessive sleep can correlate with increased mortality risks. Interestingly, while shorter sleep is clearly detrimental, sleeping beyond 9 hours does not further decrease mortality and may even increase it after reaching 10 or 11 hours.In this clip

I've been sleeping consistently for the past week, going to bed between 8:30 and 10 PM and waking up between 5:30 and 7 AM, aiming to get 7-9 hours of sleep. Normally, I sleep around 8:30/9:30 PM and wake up around 4/4:30/5 AM. Tonight, I have to stay up until 2 AM for a lab shift. What time should I wake up? Should I prioritize consistency in wake times and wake up at 5 AM to get back into a rhythm, or do I sleep in? What would Andrew Huberman tell me to do?
If I have a consistent sleeping schedule from 22:00 to 06:00 but occasionally go to bed at 23:30, is it better to extend my sleep schedule to 07:30 to get 8 hours of sleep, or to still wake up at 06:00 with only 6 hours and 30 minutes of sleep?
Did Andrew Huberman suggest that it is better to take a nap during the day than to sleep in if going to bed late, and that it's important to get up at the same time each day in the episode Sleep Toolkit: Tools for Optimizing Sleep & Sleep-Wake Timing | Huberman Lab Podcast #84 and the clip Sleep Consistency Tips?
