Your Definition
The broad, interdisciplinary field dedicated to studying the mysterious daily activity where adults try to get 8 hours and usually end up with 4, interrupted by existential dread and a cat sitting on their face. It encompasses everything from the biology of circadian rhythms to the psychology of dreams where you're back in high school, failing a math test you never studied for. Despite the name "science," a significant portion of the research is funded by grants hoping to prove that coffee is an acceptable substitute for rest.
