Debunking 11 sleep myths, Matt begins by explaining that the brain remains active, not "off," during rest. He goes on to argue that 7-9 hours of sleep is vital and warns that "adapting" to less is a delusion that masks performance deficits and long-term health risks.

Matt also shows how alcohol, warm rooms, and staying in bed while restless ruin sleep quality. He concludes with a practical, evidence-based toolkit for better rest, emphasizing the importance of a consistent seven-to-nine-hour sleep window and respecting the body’s internal circadian clock.
