Why Your Gut Keeps You Awake at Night

You've tried going to bed earlier. You've cut back on coffee. You've put your phone away before midnight. And still, sleep won't come, or won't stay.

What most people don't consider is that the answer might not be in their bedroom habits at all. It might be in their belly.

The gut and the brain are in constant communication through what scientists call the gut-brain axis, a two-way signalling network of nerves, hormones, and messenger substances. But here's what surprised me when I first came across this research: around 90% of signals travel from the gut upward to the brain, not the other way around. Your gut is not passively responding to your stress or your busy mind. It is actively reporting to it, around the clock, including at night.

When the gut is overburdened by an imbalanced microbiome, poor motility, inflammation, or accumulated tension in the abdominal organs, those signals don't quieten down when you close your eyes. They continue. And the brain, receiving a constant stream of distress from below, stays alert. Sleep becomes light, fragmented, or simply out of reach.

This is something I see regularly in my Chi Nei Tsang practice. Clients who come to me with sleep problems very often also carry a lot of tension in the abdomen. A heaviness around the digestive organs, a belly that feels tight or reactive, a nervous system that just cannot fully let go.

Chi Nei Tsang is a holistic modality of abdominal touch rooted in Taoist tradition, and it works directly with this pattern. Through slow, attentive and affectionate touch on the belly, I support the digestive organs in releasing accumulated tension, encourage the gut to return to its natural rhythms, and help the nervous system move from a state of alertness into one of genuine rest. In the world of gut health, this shift from sympathetic to parasympathetic is everything.

The gut also has its own nocturnal rhythm worth knowing about. The gut's internal cleansing wave, activates during sleep and stillness. When the gut is tense or dysregulated, this natural process is disrupted. The body cannot restore itself overnight the way it is designed to, and poor sleep and poor gut health end up feeding each other in a cycle that can be hard to break alone.

This is why I think of Chi Nei Tsang not just as digestive support, but as nervous system care and natural sleep hygiene support. The gut, the brain, and the body's ability to rest are far more connected than most of us realise.

If you lie awake at night with a restless mind, it might be worth asking a quieter question. What is your gut trying to tell you?
