Caffeine, Sleep and Finals


This content was created by the National Sleep Foundation

When final exams rear their ugly heads, college students reach for that cup of coffee. Many students depend on caffeine to stay alert in order to study and get their final papers done.


Caffeine is one of the most popular drugs in the world. A lot of foods and beverages contain caffeine include chocolate, tea, and “energy drinks.” Caffeine makes us feel more alert by blocking sleep-inducing chemicals in the brain and increasing adrenaline production. Although it appears that just about everyone can get a lot done with a little bit of caffeine, there are side effects which should be considered.

Caffeine has been known to cause anxiety, irritability, and sleep disturbances. These things can affect your ability to concentrate and focus on your final exams. Studies have shown that a lack of sleep can lead to problems completing tasks, concentrating, and making decisions.

It’s better for students to prioritize getting enough sleep to improve their performance instead of drinking that third cup of coffee.
