Ilana E. Strauss covers delayed sleep phase syndrome (DSPS) – “a disorder that affects one in 750 adults,” or about 400,000 Americans:
DSPS sufferers have internal clocks that run at least two hours slower than normal, giving them “social jet lag” which is pretty much what it sounds like: They’re out of sync with the rest of society. They struggle to keep their eyes open during morning business meetings because their bodies are convinced it’s the middle of the night.
Michael Lewis stands up for the nocturnal among us:
Lewis wrote his first book entirely after midnight, and he continues to write at night. “I can’t get the best stuff out of me any other way,” Lewis said. “I used to write until five in the morning. I think my books would be better if I could still do that.”
