🌙 How the Gut-Sleep Connection Works

  1. Circadian Rhythm & Digestion
    Your circadian rhythm depends on orderly body processes. Poor sleep disrupts your body clock, making digestion irregular and sluggish.
  2. Microbiome Diversity
    Research shows the importance of gut bacteria variety. Sleep loss lowers that diversity, which weakens digestion and immunity.
  3. Stress & Inflammation
    Lack of rest raises cortisol levels and inflammation, both of which negatively affect the the gut lining.
  4. Hormone Regulation
    Hormones like melatonin and serotonin drive both sleep cycles and gut motility. When sleep is poor, the gut-sleep connection weakens.
