Your Gut Bacteria Might Need a Nap

It’s not easy getting the recommended eight hours of sleep this time of year.  Did you know that an interruption in your regular sleep pattern could also mean an interruption to how well your gut bacteria function?

Although early microbiologists believed bacteria had no internal clocks, it is now known that microbes possess a circadian rhythm.

One study found that a startling 15% of bacterial species in the mouse gut (amounting to 60% of its total microbes) varied in abundance during the day. At night, mouse gut microbes tended to switch on genes for growing, burning energy, and repairing DNA. During the daytime, however, mice activate genes for getting rid of toxins and sensing their environment – more what you might call a maintenance mode.

Humans behave in the opposite way, with microbes supporting metabolism and growth activated during the day, and those responsible for maintenance operating at night.

And, during this oh-so-jammed packed month, don’t forget to be kind to yourself and your gut bacteria.  Take a rest. You deserve it!
