Sleep and Gut Health: What’s the Connection?

How to get a healthy gut? I hear this question all the time. Gut health, after all, is one of the hottest topics in the holistic health field.

Did you know that your gut health is incredibly important for many reasons besides your digestion? It may shock you, but your gut health even affects your sleep. Yeap, that’s right. If you have trouble falling asleep at night, wake up too much, or wake up tired even after a full night of sleep, it may be because of your gut.

Your gut health affects every single cell in your body. It also affects all areas of your health and well-being.

Do you know what else has a serious impact on your overall well-being? Your sleep. 

Chances are, when you are thinking about your sleep, your gut health is not the first thing that comes to mind. It should do. Your sleep and gut health are incredibly interconnected and affect each other greatly. Poor gut health can lead to poor sleep, and poor sleep disrupts your gut flora balance. Let’s dig into how.

Sleep and Gut Health

how to get a healthy gut

Before you learn how to get a healthy gut, you have to understand how your sleep and gut connected. What is your gut anyways and why is it so important?

Your gut is a pretty complex and sophisticated organ. Of course, one of its main roles is to breakdown and absorb your food and help to nourish your body. What you may not know is that your gut wall has neural tissue and neurotransmitters as well. This helps the release of hormones, such as serotonin. It’s becoming clear that your gut can affect your brain health and mood.

But how do your brain and gut communicate? Through the vagus nerve and hormones.

Your vagus nerve is the longest cranial nerve in your body. It extends from your cranium all the way to your abdomen. It helps to communicate sensory information and movement orders throughout your body. Your vagus nerve helps your gut to digest food, your muscles to pump your heart. It also helps to pass information to your brain by interacting with your limbic system and hypothalamus. Clearly, your vagus nerve has an important role in brain health, emotional regulation, and mood.

Your gut and brain also communicate with the help of hormones. The bacteria in your gut can affect the production of serotonin and your nervous system. When there is an imbalance in your gut flora, it can result in a drop in serotonin that may interfere with your sleep and mood. This may lead to a vicious cycle of poor gut health leading to poor sleep and poor sleep compromising your gut and overall health. 

Ways Your Gut and Sleep Affect Each Other

Remember, your body is an interconnected system. Everything affects each other. Poor gut health has many consequences, including sleep problems. Poor sleep doesn’t go without consequences and may lead to fatigue, inflammation, gut flora imbalance, and disease. 

There are a variety of ways that your sleep and gut health influence each other. 

  • Inflammation: When there are changes in your gut and your microbiome becomes out of balance, it may lead to inflammation and a compromised immune system, which may affect your ability to get quality sleep.
  • Dysbiosis: Dysbiosis refers to an imbalanced or compromised microbiome that can result in irritable bowel syndrome (IBS), ulcerative colitis, Crohn’s disease, and other issues. Having digestive troubles can keep you up at night.
  • Diversity of Gut Bacteria: A compromised gut microbiome with less diverse bacteria may reduce melatonin and serotonin production, which may compromise your ability to sleep. It may even result in sleep apnea and other sleep airway disorders which may further impair your gut health.
  • Sleep Deprivation: Sleep deprivation and inflammation have been linked by research. Sleep disorders may disrupt your immune system and your nervous system that can result in further sleep issues and gut discomfort.
  • Circadian Rhythms: Following a healthy circadian rhythm is incredibly important. When you sleep irregular hours not following a healthy sleep cycle or perhaps experiencing insomnia, it may affect your gut health negatively.
  • Leaky Gut Syndrome: Leaky gut syndrome may lead to all sorts of health issues, including inflammation, fatigue, and sleep issues.
  • Stress hormones: Too much stress results in increased stress hormone cortisol in your body. However, too much cortisol may impact both your sleep and gut health leading to a vicious cycle of insomnia and gut health issues.
