How It Works

How does alcohol affect sleep?

As a depressant, alcohol dampens arousal levels, making it notoriously good at helping people fall asleep quickly. However, the work of metabolising alcohol later disrupts your brain.

Notably, drinking alcohol slows production of glutamine. Afterward, the body works to recover the deficit by turning up the glutamine dial. The chemistry imbalance can wake
you up more often and suppress REM sleep.
