Another study showing the relationship between sleep and memory. "The post-sleep boost in memory accessibility may indicate that some memories are sharpened overnight." (It might be worth reminding your students that a good study strategy includes a complete night's sleep!)
Interesting study showing the importance of consistent sleep in the weeks and months before exams, and not just the night before or catching up on weekends. Your bleary-eyed colleagues at the CIP suspect we would see this effect among faculty and staff as well.
Your circadian rhythms may have as much to do with the feeling of sleepiness as the actual amount of sleep you get. That has interesting implications for class scheduling and advising.
We talk a lot about the way sleep functions as a necessary part of learning, but the way sleep helps us handle stress also seems important when dealing with our overcommitted, underslept students and colleagues.
