It seems like every time I meet someone who claims they need less than 6 hours of sleep, they are either notably sleep deprived, or they exclude the fact they sleep longer on the weekend and don&#x27;t bother counting all the random naps.<p>If anyone knows of a credible resource and testimonials of a program that lets a person go from 7-8 hours of sleep to 4-5 hours please share a link. In every other domain of human ability you can usually train for improvement and I am skeptical that sleep can&#x27;t be one. This assumes people aren&#x27;t reporting bad data or secretly taking Provigil.
