Steel has given that 20-hour figure when describing her“exhausting”process in the past:“I start thebook and don 't leave my desk until the first draft is finished.”She goes from bed，to desk，to bath，tobed，avoiding all contact aside from phone calls with her nine children."I don 't comb my hair for weeks,”she says.Meals are brought to her desk，where she types until her fingers swell and her nails bleed.The business news website Quartz held Steel up as an inspiration，writing that if only we all followedher“actually extremely liberating"example of industrious sleeplessness，we would be quick to see results.well，indeed.With research results showing the cumulative effects of sleep loss and its impact onproductivity，doubt has been voiced about the accuracy of Steel's self-assessment.Her output may beundeniable，but sceptics have suggested that she is guilty of erasing the role of ghostwriters (代笔人) atworst，gross exaggeration at best.
Steel says working 20 hours a day is “pretty brutal physically.”But is it even possible?“No,”saysMaryanne Taylor of the Sleep Works. While you could work that long，the impact on productivity wouldmake it hardly worthwhile. If Steel was routinely sleeping for four hours a night，she would be drasticallyunderestimating the negative impact，says Alison Gardiner，founder of the sleep improvement programmeSleepstation.“It's akin to being drunk.”
lt's possible that Steel is exaggerating the demands of her schedule. Self-imposed sleeplessness has“become a bit of a status symbol", says Taylor， a misguided measure to prove how powerful and productive you are.Margaret Thatcher was also said to get by on four hours a night，while the 130-hour work weeksendured by tech heads has been held up as key to their success.
That is starting to change with increased awareness of the importance of sleep for mental health.“People are starting to realise that sleep should not be something that you fit in between everything else,"says Taylor .
But it is possible—if statistically extremely unlikely—that Steel could be born a “short sleeper”withan unusual body clock，says sleep expert Dr. Sophie Bostock." It's probably present in fewer than 1% ofthe population.”
Even if Steel does happen to be among that tiny minority，says Bostock，it's “pretty irresponsible”tosuggest that 20-hour days are simply a question of discipline for the rest of us.
