Hi ...
I think my question may have been lost in the shuffle. I hope somone can
help me for I'm still struggling with the research regarding the circadian
rhythm of sleep. As I mentioned in my initial email, current researchers
have criticized previous research indicating that the sleep CR is 25 hours
long, basing this criticism on the fact that bright levels of light were
used. In fact they conclude, "Light is the most powerful synchronizer of the
biological clock." The current researchers, who are reporting a 24 rather 25
hour cycle, also used light, constantly exposing their subjects to "subdued"
levels. I don't understand how they can obtain a valid measure of the length
of CR when they also used light. Wouldn't it be better to put subjects in a
naturalistic setting where they would be exposed to natural light and dark
and have them record physiological functions, time at going to
sleep/awakening, etc.?
Thanks in advance to anyone who can help me!
