New research has found a connection between irregular sleep patterns, also known as social jet lag, and harmful gut bacteria. Even minor changes in sleep schedules, as little as 90 minutes, can lead to shifts in gut bacteria composition, promoting species associated with health problems like obesity and heart disease. The study, a collaboration between King’s College London and personalized nutrition company ZOE, examined the relationship between social jet lag and factors like diet quality, dietary habits, inflammation, and gut microbiome composition in a group of 934 individuals.
Previous studies have shown that shift work can disrupt the body clock and increase the risk of weight gain, heart issues, and diabetes. However, this research sheds light on the impact of even small variations in sleep timings, such as waking up with an alarm on workdays versus waking naturally on non-workdays, for individuals with regular working hours.
The study emphasizes the significance of maintaining consistent sleep patterns for good health. The gut microbiome, which consists of microbes in the digestive system, plays a crucial role in overall health by producing toxins or beneficial metabolites. Specific microbial species in the gut can influence an individual’s risk of long-term health conditions like diabetes, heart disease, and obesity, and the composition of the microbiome can be influenced by the food one consumes.
The research findings suggest that having social jet lag is associated with lower diet quality, higher consumption of sugary beverages, and reduced intake of fruits and nuts, all of which can impact the abundance of certain microbiota in the gut. Some of the microbial species found to be more abundant in the social jet lag group have unfavorable associations with health, including indicators of poor diet quality, obesity, and cardiometabolic health, as well as increased inflammation and cardiovascular risk.
The study highlights the importance of regular sleep patterns for maintaining a healthy gut microbiome and overall well-being. By adopting consistent sleep schedules, individuals may positively influence their gut health, reducing the risk of chronic illnesses and promoting better metabolic and cardiovascular outcomes.

Frequently Asked Questions (FAQs) about Gut Health
Question 1: What is social jet lag, and how does it affect gut health?
Answer: Social jet lag refers to the internal body clock shift that occurs when sleep patterns vary between workdays and days off. New research suggests that even a 90-minute change in sleep schedule can influence gut health by promoting harmful gut bacteria associated with obesity and heart disease.
Question 2: What are the findings of the study regarding the link between sleep patterns and gut bacteria?
Answer: The study, conducted by King’s College London and ZOE, found that inconsistent sleep schedules can lead to shifts in gut bacteria composition. People with social jet lag had lower overall diet quality, higher consumption of sugar-sweetened beverages, and lower intake of fruits and nuts, affecting the abundance of specific gut microbiota.
Question 3: What is the significance of the gut microbiome in relation to health?
Answer: The gut microbiome plays a crucial role in health, as it can either produce toxins or beneficial metabolites. Specific microbial species in the gut are linked to an individual’s risk of developing long-term health conditions such as diabetes, heart disease, and obesity.
Question 4: How does this research differ from previous studies on shift work and health risks?
Answer: While previous research focused on the impact of major disruptions like shift work on health, this study highlights the importance of even minor inconsistencies in sleep timings. It emphasizes the need to maintain regular sleep patterns for a healthy gut microbiome and overall well-being.
Question 5: Who participated in the study, and what were the key findings?
Answer: The study involved 934 participants from the ZOE PREDICT study, mostly lean and healthy individuals with regular sleep schedules. Researchers found that a 90-minute difference in the midpoint of sleep was associated with differences in gut microbiome composition, particularly species linked to health issues.
Question 6: What are the potential implications of the research findings?
Answer: The research suggests that improving sleep time consistency may lead to beneficial changes in the gut microbiome and related health outcomes. Maintaining consistent sleep patterns could positively influence gut health, reducing the risk of chronic illnesses and promoting better metabolic and cardiovascular health.
