You have explained how even if we think we are sleeping well, if there is light, that light is interfering with quality of our sleep. Is this also true of noise? If you live say, on a noisy street next to a bar, but have learned to fall asleep despite lots of loud noise, is that noise still being processed in a way that interferes with your sleep cycle/quality of sleep?
Considering that after sleep deprivation, subjects in several studies had higher levels of cortisol later in the day, and considering also that deliberate Heat Exposure (aka Sauna) decrease the level of cortisol. Is it safe to say that shift workers should consider the use of sauna before and after shift works ? What would be the protocol ? I think a lot of shift workers might not know the bad effect of sleep deprivation on their body and how to counter these bad effects. Thank you very much for considering this question.
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?
