Sleep
Can't study late at night?

Hiya Alice,

My problem is this: whenever I have to study late at night, or anything late at night, I usually have trouble (a lot of trouble) concentrating on whatever it is that I have to do. I'm not going to try anything like No-Doz, but when I drink coffee or anything with caffeine, it just knocks me out even faster. I can't believe it — it's like caffeine's some kind of sleeping potion for me. Some of my friends say eating while you work can help you stay up. I tried that, too. Didn't work. Any suggestions? Or am I just better off sleeping and leaving the work 'till the next day?

Dear Sleepy,

Sleep is a precious commodity at college, and invariably in short supply. With too many activities and too few hours, sleep invariably comes out on the short end of your time allotments. Sleep is both relentless (nobody lives without it) and flexible (which tempts us to abuse it). While our body remains immobile, nearly every organ and system is undergoing measurable changes, some of them drastic, during sleep. And while the brain seems nonreactive to outside stimuli, it is still processing and filtering sensory information from the outside and is as active (albeit in different ways) as the awake brain.

Why do some people need to sleep longer than others? Perhaps for the same reason that some people are taller than others, or run faster: a mixture of genetic and lifestyle factors. Some studies have shown that short sleepers tend to be characterized as action-oriented on personality tests and long sleepers tend to appear more introspective. In any case, you need to use your own body, not someone else's behavior, as a guide for your sleep needs. What you need for sleep may vary greatly from your friends and roommates. In other words, do your studying earlier and get some sleep at night!
