In the last two weeks, I have finally convinced my wife to allow us to sleep in the pitch dark. I've used tinfoil on the windows while she decides what kind of shades she wants to use. Anyway, I've been going to bed between 9:30 and 11:00 and waking up between 8:30 and 9:30 everyday. I've gotten around 11 hours of sleep a couple of nights!I have averaged around 8 and a half hours for the past year or so, but I am normally an early riser and this isn't going to work for me when I have to go back to work (I'm on vacation at the moment.) The reason I seem to be able to sleep so long is because it is still so dark in my room in the morning.
So, I guess i have two main questions about this:
First, can you get too much sleep per night? How would you know if you were getting too much?
Second, is it bad to wake up in a pitch black room? Does it mess up your circadian rhythm as much as sleeping in the bright light?
