Get 8 Hours!

Sleep is a critical factor in UT students’ academic success and well-being, and for many students it is in short supply. Students have strenuous schedules, with academic requirements, social and personal needs, sports, clubs, Greek organizations, employment, and planned activities all competing for their time. With so many activities and too few hours, sleep often comes up on the short end with time allotment. This can result in sleep deprivation and some students depending on caffeine and other stimulants to stay awake.


What Happens When You Sleep?

REM Sleep, Dreams, and the Circadian Rhythm:
The most vivid and memorable dreams take place during REM (Rapid Eye Movement) sleep. During REM sleep, eye movements correspond with what the sleeper is looking at in the dream, while the rest of the body is paralyzed at the brain stem. The sleep and dream cycle varies between individuals, but the majority of healthy people exhibit a consistent pattern illustrated by the graphs above.

The Circadian Rhythm is a 24-hour cycle the human body goes through each day. Within this day and night cycle there is a 6- to 10-hour period in which we sleep. This sleep period includes both deep sleep and REM sleep.
