In your most recent AMA #2, you thoroughly cover sleep cycles and the importance of each (Deep, REM, etc), that deep sleep and REM should be relatively balanced with each other at 30% (and not worrying about exactness here)... You also emphasize how alcohol and caffeine should ideally not be consumed within an 8-12 window prior to sleep to avoid affecting Deep sleep. After listening to your podcast on the effects of alcohol on our nervous system, I have since stopped drinking more than the 1-2 drinks per week and have felt my ability to stay asleep after waking up improve dramatically (I take the Momentous sleep packs each night 30 - 60 min before bed. They are very effective. TY!!) I recently went to a psilocybin retreat to aid in my anxious habits of thought (which has also aided me in reducing my cravings for alcohol when stressed) and would love to know what the effects of psilocybin are on our sleep cycles as well. I read a study that said it increased SWA latency and inferred that this was good as they associated it positively affecting depression in the study like SSRI's... but I must admit I don't understand what this means. I don't take any anti-depressants or any medications at this time and am focused on optimizing my health. Any light you could shed on psilocybin specifically on sleep would be amazing. Thank you for all you're doing for this world. My focus on health within my family and friend groups is finally gaining attention thanks to you!
Is there a specific part of the brain which is active for nighttime teeth clenching, and steps to take to avoid activation / turn off? Clearly one should follow your sleep guidelines plus effective ways to limit [di-]stress. But is there any thing one can do that specifically targets the parts of the brain that are active during clenching. I’ve found many things that help at the 10-20%level and need that final push to break habit/cycle. I have good sleep habits; 7-8hrs total; 3-4 hrs from rem/deep. Thank you kindly Dr Huberman. Sonya
Your explanation of the awareness of one's 90 minute ultradian seems rather subjective. Are there any objective technological metrics such as CT/MRI, blood chemistry, cardiology, or other measurements available to confirm one's ultradian rhythm? Also, any research on the placebo effect of a subjective ultradian mindset?
Dr. Huberman, I keep hearing you reference an upcoming podcast on ego depletion. When you do it, can you address the study mentioned in this article that asserts the ego depletion wasn't really a thing? https://www.psychologytoday.com/us/blog/how-do-you-know/202011/how-willpower-wasnt-the-truth-about-ego-depletion
