When we lie awake at night, unable to sleep, we usually blame stress, depression, anxiety, adrenaline or the memory of something stupid we said in 2003. But what if our guts were actually the culprit? What if the trillions of microbes sitting in our small intestines – known collectively as the microbiome or microbiota – were actually affecting our mood, digestion, overall health and ability to get a full eight hours’ shut-eye? Scientists are beginning to suspect there is a strong, if as yet unproven, link between gut health – the diversity and wellbeing of bacteria in the stomach, small and large intestines – and sleep health.

“This is an embryonic field right now in the annals of sleep research,” says Matt Walker, the author of Why We Sleep and the director of the Center for Human Sleep Science at the University of California, Berkeley. “We know an enormous amount about the relationship between a lack of sleep and appetite, obesity and weight gain, as well as aspects of insulin resistance and glucose regulation. What we don’t fully understand yet is the role of the microbiome in sleep.”
