A recent study may be the first to highlight the link between detriments to health associated with an inconsistent sleep schedule and gut micro-bacteria.
The study was published on Wednesday in the European Journal of Nutrition, a peer-reviewed medical journal focused on nutrition science.
The study highlights a sleep-related phenomenon known as social jetlag (SJL). Sleepcycle.com describes SJL as “the habit of having two separate, distinct sleeping patterns.” It goes on to explain the SJL is often the result of having “very separate weekday and weekend routines, although it can of course occur in other circumstances as well.”
The study aimed to examine the effect SJL has on other dimensions of health. In the paper, the researchers state their purpose as to “explore the relationship between social jetlag (SJL), a parameter of circadian misalignment, and gut microbial composition, diet, and cardiometabolic health.”
For the purpose of the study, the researchers measured SJL as the difference in time between the midpoints of the subjects’ sleep on weekdays and on weekends. For example, if the midpoint of one’s sleep was 4 a.m. on the weekend vs 2 a.m. on a weekday, that would be a difference of two hours.

Consistent sleep is important for health
These changes can be caused by even a small degree of misalignment in one’s sleep schedule, this could have long-term effects and cause chronic non-communicable diseases.
The best remedy remains a healthy regular sleep schedule, but if that is not possible due to social constraints such as work schedules, then there are some other solutions.
One of these is eating a more healthy diet which could include avoiding potatoes, and sugary drinks, as well as fewer fruits and nuts.
