sleep cycle - waking and then getting up mid cycle?
Hi Professor Huberman, If my typical sleep-wake time is 11:00pm-7:00am but I happen to wake up say around 6:00 or 6:30am one morning - is it better for me to get up, or is falling back asleep and then waking up to an alarm at 7:00am mid-sleep cycle ok? Are there negative effects to getting up from an interrupted sleep cycle?
Proper evening sun viewing
Hello Professor Huberman, Regarding the evening sun light viewing - does the brightness matter as much here? I know in the morning we are aiming for the brightest light (without hurting our eyes). Is that similar in the evening, or does a cloudy "sunset" still have the same impact on helping to set our circadian rhythm and set us up for sleep that night?
CO2 tolerance protocol
Hi Professor Huberman! You've mentioned the CO2 tolerance test as a way to measure recovery after sleep. I've been using this each morning and tracking my stats. Quick question - does the test "end" when I end up swallowing, or when I completely run out of breath. For example, I typically will feel the urge to swallow around 20 seconds, but can keep exhaling for around 60 seconds. What I have noticed is that the two don't always correlate either - sometimes I need to swallow sooner but have an overall longer exhale, and sometimes vice versa. Hoping you can help me better understand how to measure this and to make sure I'm doing it correctly. Thank you!
Best protocol to improve agility?
I am really interested a practical protocol to increase agility, especially vertical jump. I think there are so much confusion how to gain more muscle 2 fiber which helps to have more agility, not as clear as strength or hypertrophy. I would be more than happy if you can clear this to me and I hope to many athletes too.
Brain areas and neurochemistry involved in planning and prioritizing
What are the brain areas and neurochemistry involved in planning and prioritizing? Why do some people find it SO difficult to plan and prioritize? What factors are involved? What helps one shift through the threshold between default mode to attentional mode? How can we mechanize or develop a protocol to help others adapt the 'brainstorming/divergent' thinking and 'convergent thinking' to planning, prioritizing, and work bouts?
