Stress has a direct and measurable impact on your gut and immune system. When you’re under chronic stress, your body releases cortisol and other stress hormones that suppress immune function, disrupt digestion, and even change the composition of your gut microbiome.

For someone dealing with CIRS or other environmental sensitivities, stress doesn’t just make symptoms worse—it can actually slow or prevent healing. That’s why addressing emotional and mental health is just as important as diet.

Simple daily practices like deep breathing, journaling, stretching, or time in nature can calm the nervous system and reduce inflammation. For some, prayer or meditation may be grounding. The goal isn’t to eliminate stress but to build in regular recovery time so the body has a chance to repair and rebalance.
