A new study suggests that the bacteria living in our gut might play a role in insomnia, offering fresh insight into how digestive health could affect sleep.
Researchers looked at data from over 386,000 people with insomnia and found that certain types of gut bacteria were more common in those struggling with sleep. The study, published in General Psychiatry, highlights a possible connection but says the exact reasons are still unclear.
Other Triggers for Insomnia
The UK’s National Health Service (NHS) notes that insomnia can also be caused by stress, anxiety, depression, alcohol, caffeine, or irregular work schedules.
Why It Matters
While past research has linked the gut to sleep regulation, this is one of the largest studies showing that gut bacteria could raise the risk of long-term insomnia.
What’s Next?
Experts say more research is needed to find out if gut bacteria directly cause poor sleep or influence other body processes that affect it. In the future, treatments like probiotics, prebiotics, or diet changes may help improve sleep by restoring gut balance.
