Often, we believe that holding on to hurt protects us from being hurt again. But in reality, it only perpetuates pain without fixing the underlying wound. And here’s the part we rarely acknowledge: unforgiveness doesn’t just affect emotions—it leaves a measurable imprint on physical health.
Research shows that chronic emotional stress raises blood pressure, increases inflammation, weakens immunity, and accelerates the wear and tear of the nervous system. In functional medicine, we call this the mind-body connection—where unresolved emotional trauma translates into biological stress.
Forgiveness, then, isn’t weakness. It’s strength. It’s choosing to release what holds us back so we can move forward healthier, freer, and more resilient: mentally, emotionally, and physically.
Why Forgiveness Matters for Your Health
Functional medicine views health through a systems-based lens. That means unresolved stress doesn’t just stay in your head, it shows up everywhere in the body. Here’s how unforgiveness can manifest:
- Increased blood pressure: Chronic anger and resentment keep cortisol and adrenaline levels elevated, which can harden arteries and strain the cardiovascular system.
- Weakened immune system: Long-term stress decreases natural killer (NK) cell activity, leaving the body more vulnerable to infection and even cancer progression.
- Brain changes: Chronic unforgiveness keeps the amygdala—the brain’s fear center—on high alert, while impairing prefrontal cortex activity, making it harder to focus, plan, and regulate emotions.
- Digestive issues: The gut-brain axis reacts strongly to unresolved emotional stress, which can lead to irritable bowel symptoms, poor nutrient absorption, or microbial imbalances.
By choosing forgiveness, you actively reset these pathways, lowering stress hormones, calming the nervous system, and supporting whole-body healing.
6 Tips to Practice Forgiveness
Here are six steps that combine emotional resilience with functional medicine principles to help you practice forgiveness in daily life:
- Acknowledge your feelings. Suppressing emotions only keeps them stuck in the nervous system. Recognize anger, sadness, or disappointment without judgment. Journaling or talking with a trusted friend can help.
- Consider the benefits of forgiving. Think of forgiveness as medicine. Studies show it reduces cortisol, lowers blood pressure, and improves sleep. It clears toxic emotional waste from your system.
- Decide to forgive. Forgiveness is a choice, much like choosing to eat well or exercise. You don’t do it because the other person deserves it—you do it because you deserve freedom and healing.
- Practice letting go. Imagine releasing a heavy rock into a river. That’s what letting go of resentment feels like. It doesn’t mean condoning harm—it means no longer letting it weigh down your body and brain.
- Move forward. Shift focus from the pain of the past to the opportunities ahead. Each new experience creates fresh neural pathways—helping your brain rewire for resilience instead of reactivity.
- Follow a mentor. Jesus Christ is the ultimate example. He modeled radical forgiveness, even in the face of suffering. His example empowers us to lean into grace, even when forgiveness feels impossible.
Forgiveness Heals
At Resolve Medical, we often remind patients that healing isn’t just about diet or labs—it’s also about rewiring how we handle stress and emotions. Forgiveness is one of the most profound ways to support both brain and body health.
It lowers inflammation. It balances stress hormones. It helps restore focus and clarity. And most importantly, it opens the door to joy, peace, and a future no longer defined by the past.
Forgiveness may not happen overnight. But every step toward it is a step toward health.
