The excitement and get up and go from the holidays are often followed by a lull, a sadness, and for some even the blues. While it is not yet a syndrome it is a real thing for some people. You may have enjoyed time off work, spent time with family and friends and now find yourself feeling down. The feeling will pass as you get back to your routines but there could be more going on. Your gut health could be leading the downward spiral. Being off your routine, eating all the wrong things, over indulging in alcohol, extra sweets and skipping those daily probiotics can all mess with your gut. Messing with those good healthy probiotics in your gut can affect your mood. Sounds strange but true. In fact, there is a growing body of evidence that your gut health directly affects your over all well being, your immune, mental, mood, emotions, and of course physical health. How is that possible? We all know that your brain contains a number of neurons that tell your body how to behave but your gut also contains neurons which are connected to your brain through the nerves in your nervous system (the main one is called the “Vagus” nerve). Your brain also uses chemicals produced by the body called neurotransmitters which control feelings and emotions but did you know that your gut also produces neurotransmitters (via all the microbes, good bacteria) that live inside of you? Some of those feel good neurotransmitters such as serotonin and GABA are produced by your healthy gut bacteria. Given this gut-brain interaction and how it affects mood, may help you to better understand that if you failed to care for your gut over the holidays, you are feeling a bit blue now.
