New research highlights the connection between gut bacteria and insomnia—and what it could mean for your digestive wellness.

Sleepless nights can take a toll on your health, and the culprit may be closer than you think. Recent research suggests that the balance of bacteria in your gut can influence insomnia, affecting both how well and how long you sleep.

A study analyzed gut microbiome data for thousands of individuals and found that certain bacteria may increase or decrease insomnia risk. In turn, insomnia itself may change the makeup of your gut microbiome, creating a complex two-way relationship. Read the full Newsweek article here for more details.

Key Insights

  • The Odoribacter class of gut bacteria influences compounds that regulate inflammation, neurotransmitters, and circadian rhythms.
  • Diet, lifestyle, stress, and environment all shape your gut microbiome, which may impact sleep quality.
  • Interventions such as probiotics, prebiotics, or fecal microbiota transplantation (FMT) are being explored—but lasting benefits usually require combined dietary and lifestyle strategies.
