When your body is in fight or flight, it isn’t able to direct much energy towards proper digestion.
Meditation & Digestion.
Humans were never designed to be stressed out all the time, and when we learn to calm our nervous systems, our health improves dramatically. Our nervous system and the gut are inextricably linked.
Irritable Bowel Syndrome
One study focused on teaching the Relaxation Response Meditation to those with Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD). A one-year follow-up found that many of them continued to show “significant additional reduction in pain and bloating.” (1-3) Another more recent pilot study looked at Relaxation Response Meditation's impact on genomic markers related to IBD. They found that meditation reduced RR-MBI response genes' expression was most significantly linked to inflammatory response, cell growth, proliferation, and oxidative stress-related pathways. (4)
But you don’t need IBS or IBD to reap the digestive benefits of meditation.
Weight Loss
Meditation can also help with weight loss. A 2017 meta-analysis of 19 different studies (5) found that diet and exercise work in the short term, but eventually, the study participants’ weight was gained back after the programs ended. On the other hand, weight loss protocols that included mindfulness interventions such as meditation and healthy eating and exercise were seen to be more effective in reducing weight and keeping it off.
So, why is it possible that meditation helps when it comes to weight loss? Loosely put, it goes back to living a fight-flight lifestyle. If our cortisol levels are consistently high, we have a greater chance of obesity over time, according to a 2017 study. (6) Some research shows that generalized meditation helped reduce cortisol and C-reactive protein levels. (7)
