Warm thanks for producing and sharing such informative podcasts🤞 I have a question on "sleep management for night owls" that I would appreciate if you could address in an episode. I am a night owl, and as a medical student, I need to attend 8 AM classes. However, I am unsure how to adjust my sleep schedule. Could the habit of staying up late innately have negative effects on the brain? How can individuals like me protect their mental and brain health and maintain healthy sleep? Best regards.💗
