Newswise - Why people get drowsy and fall asleep, and how caffeine blocks that process, are the subjects of a new study by researchers at UT Southwestern Medical Center.

When cells in a certain part of the brain become overworked, a compound in the brain kicks in, telling them to shut down. This causes people to become drowsy and fall asleep. Alter that natural process by adding coffee or tea, and the brain compound - called adenosine - is blocked, and people stay awake.

These findings, available online and in the April 21 issue of the journal Neuron
