Is Poor Gut Health Responsible For Your Sleep Problems?

The truth is that your gut may be what is keeping you awake.

Gut health is connected to everything in your body; I remind my patients this often. According to new research, even your good night sleep may depend on your digestive health.

You may blame stress, anxiety, memories popping up, depression, racing thoughts, adrenaline, loud neighbors, too much light, and so on for lying awake at night. The truth is that your gut may be what is keeping you awake.

Study: The Gut-Sleep Connection

New research indicates that there is a strong correlation between your microbiome health and sleep health. Matt Walker, director of the Center for Human Sleep Science and author of Why We Sleep explained the connection between your appetite, obesity, weight gain, insulin resistance, glucose regulation, and the lack of sleep.

What we know is that sleep deprivation decreases leptin in your body. Leptin is responsible for the feeling of fullness, therefore such decrease can lead to overeating and obesity. Lack of sleep can also affect your impulse control leading to mindless eating and unhealthy choices, such as giving into the desire for comfort foods and sugary junk foods. Poor food choices lead to poor gut health, and by promoting unhealthy eating habits, poor sleep leads to an unhealthy microbiome too.

Dr. Michael Breus, a clinical psychologist and fellow of the American Academy of Sleep, agrees that focusing on improving gut health can become the new sleep therapy. A healthy gut can help with sleep-related physiological functions, including affecting hormones responsible for sleep and wakefulness, altering sleep-wake cycles, and shifting circadian rhythms.

How To Improve Microbiome Health

A long list of studies show that probiotics and prebiotics improve your gut health. According to a recent study and a new documentary, prebiotics can have a positive effect on sleep. (1, 2)

Tim Spector, a professor of genetic epidemiology at King’s College London and author of The Diet Myth, is another believer in the gut and sleep relation. A poor gut health negatively affects your mood and mental health. Depression, bipolar depression, anxiety, and even mild disturbances of mood can lead to insomnia and other sleep issues.

The connection is not clear though. Some people’s mental health improves through better sleep, and some people’s sleep improves through improvement in their mental health. Spector believes that it is critical to deeper examine and research the role of the gut in this and other health related issues. He believes that an improved gut-friendly diet can improve both sleep and mental health. Christine Hansen, author of Sleep Like a Boss also agrees that diet is essential for getting a quality sleep.

Though experts agree that more research is needed on the gut-sleep connection, we do know enough to indicate that eating a whole foods diet with probiotics and prebiotics is essential for gut health and a good night sleep. (3

Great article!


This is a very helpful article. And a lot of the recommended food choices, I actually like. Lack of sleep does make me eat more sweet stuff for energy, but I don’t eat a lot. I have to take sleeping pills to help me sleep. I’m not in a good environment just now. I’ve got bad neighbours. I can’t eat properly in the morning or during the day. I can’t eat bananas. But, I bought seeds and nuts yesterday, I’m hoping to make improvements. Thanks. Very interesting
