Sometimes we make the decision to fall asleep early. Then the next day, tempted by a good Netflix series, we fall asleep later. And that can have consequences for your gut microbiota. Indeed, a recent study conducted by researchers from King’s College London and the nutritional science company ZOE reveals that lack of sleep has an impact on our intestinal bacteria. « We know that major sleep disruptions, like shift work, can have a profound impact on your health. This is the first study to show that even small differences in sleep schedules over the week appear to be linked to differences in gut bacterial species. », explains the study’s lead author, Dr. Wendy Hall of the School of Life Course & Population Sciences.
Sleeping at different times is really not a good idea
The specialist points out that some of these associations were related to dietary differences, but our data also indicate that other, as yet unknown, factors may be involved. We need intervention trials to to determine whether improving sleep time consistency can lead to beneficial changes in the gut microbiome and associated health outcomes. » And a disordered intestinal microbiota has more global consequences on the state of health since it will produce toxins. Thus, it can accentuate diabetes, heart disease and obesity.
The researchers analyzed blood, stool and gut microbiota samples from study participants whose sleep was irregular. Their findings are alarming. “ While previous studies on the association between social jet lag and risk factors metabolic tests were carried out in obese or diabetic populations, this cohort was mainly composed of lean and healthy individuals, most sleeping more than seven hours a night throughout the week. », specifies the scientific team.
