The Gut-Sleep Connection

THE GUT-SLEEP CONNECTION 😴⁠

If you follow me on Instagram, you will have heard me talk about how our gut health impacts so many other systems of our bodies, from the immune system to the health of our skin. Sleep is another area that both impacts – and is impacted by – our gut health.

The relationship between gut health and sleep is reciprocal, with our digestive function and gut microbiome influencing our sleep, and a sleep deficit or compromised circadian rhythm (natural body-clock) affecting our digestive function and gut microbiome.

The Gut Sleep Connection

Why It’s Important:

🧠 Studies have shown that diversity in the beneficial bacteria of our gut microbiome has a positive correlation with both time spent asleep and the quality of our sleep.

🧠 Likewise, when there is less diversity in our gut microbiome (which may be due to a variety of factors such as recent antibiotic use or consuming a diet low in plant diversity), this has a negative correlation with sleep.

🧠 Brain function, stress levels and mood balance are all impacted by the quality of your sleep. ⁠

🧠 Our gut microbiome produces neurotransmitters which impact sleep, such as GABA.⁠

🧠 Given that 90% of our serotonin (the “happy hormone”) is made in our gut, if there is dysbiosis in the gut (an imbalance of the good and bad bacteria), the production of serotonin can become impaired, which can influence the quality of our sleep.

🧠 We produce 400x the amount of melatonin (our sleep hormone) in our gut than in our brain’s pineal gland.⁠

Summary

If you want a good night’s sleep, supporting your gut health is essential. There are so many ways to look after your gut health, from increasing your fibre intake to adding more plant diversity into your diet. I’ve written a whole blog post about The Gut Microbiome and another post sharing my 6 Top Tips for Gut Health.
