Sleep expert challenges eight-hour myth for athletes in new book

Greg Meehan, a sleep expert for athletes, emphasizes that many professional sportspeople do not understand proper sleep practices. His new book challenges the common belief that everyone needs eight hours of sleep, suggesting that individual needs vary significantly. Meehan explains the importance of circadian rhythms and sleep cues, advising athletes to establish consistent sleep schedules and reduce light exposure before bed. He highlights the significance of deep sleep and REM stages for recovery and performance. He also warns against the overuse of sleep tracking devices, which can lead to anxiety about sleep quality. Meehan encourages athletes to focus on overall sleep habits rather than fixating on data from trackers.
