As if you didn’t already have enough to worry about to keep you up at night, a new study indicates that poor sleep can negatively affect your gut microbiome, which can, in turn, lead to additional health issues.
What you may be asking yourself right now is: “what in the world is a gut microbiome?” Simply put – it’s all the microorganisms (bacteria, viruses, protozoa and fungi) and their genetic material found in your gastrointestinal (GI) tract. And yes, we all have these in our GI tract, but not all at the same levels (diversity.) As it turns out, it’s this diversity that could be the key. Gut microbiome diversity, or lack thereof, is associated with other health issues, such as Parkinson’s disease and autoimmune diseases, as well as psychological health (anxiety and depression.) The more diverse someone’s gut microbiome is, the likelihood is they will have better overall health.
Getting a good night’s sleep can lead to improved health, and a lack of sleep can have detrimental effects. We’ve all seen the reports that show not getting proper sleep can lead to short term (stress, psychosocial issues) and long-term (cardiovascular disease, cancer) health problems. We know that the deepest stages of sleep is when the brain ‘takes out the trash’ since the brain and gut communicate with each other. Quality sleep impacts so many other facets of human health.
So what determines someone’s gut microbiome? According to Robert Smith, Ph.D., an associate professor and research scientist at Nova Southeastern University (NSU) Halmos College of Natural Sciences and Oceanography, there are a couple of factors that come into play.
One is genetics – some people are predisposed at a genetic level to have a more diverse gut microbiome than their friends and neighbors. Another factor is drugs – certain medications, including antibiotics, can have an impact on the diversity of your gut microbiome. He also said that your diet plays a factor as well.
To see the impact of sleep a recent study examined the association between sleep, the immune system and measures of cognition and emotion. Understanding how these parts of human physiology work may lead to a better understanding of the “two-way communication” between the person and their gut microbiome, and could lead to novel sleep intervention strategies.
The preliminary results are promising, but there’s still more to learn, eventually people may be able to take steps to manipulate their gut microbiome in order to help them get a good night’s sleep.
