This report explores the differences between "larks" and "owls" in terms of their sleep patterns and chronotypes. It highlights the role of the PER3 gene in regulating the sleep/wake cycle and the existence of "extreme larks" and "extreme owls" in the population. The report also mentions the importance of gut health and how it can affect sleep. The author notes that an individual's chronotype can fluctuate with age and that young children and the over-60s tend to be larks, while teenagers tend towards owl-like behavior. The report concludes by suggesting that cognitive behavioral therapy (CBT) may be a solution for insomnia problems.
