Sleep problems: Why you sleep poorly (+solutions)
In this video, I'll show you why waking up at specific times during the night can provide valuable insights into your metabolism, nervous system, and hormone regulation. I'll explain how organ rhythms, cortisol levels, blood sugar, digestion, liver detoxification, and digital stress all affect your sleep. You'll gain medically sound insights from chronobiology, stress research, and sleep medicine—and concrete strategies for stabilizing your nighttime rhythm and sustainably improving your sleep.
Enjoy the video,
Dr. Lutz Graumann
