Healing Through Humor: How Laughter Impacts Our Bodies and Minds

We’ve all heard the saying, “Laughter is the best medicine.” But what if there’s more truth to that phrase than we might think? As mental health professionals and wellness enthusiasts, it’s important to understand how positive emotions like humor can directly impact our physical well-being. Recent research highlights a fascinating connection between laughter and measurable health benefits, which challenges us to rethink how we approach holistic healing.
The Japanese Study on Laughter and Blood Sugar
One particularly compelling study conducted in Japan focused on individuals with type 2 diabetes. Researchers divided participants into two groups: one group attended a comedy show, while the other group sat through a monotonous, uninspiring lecture. After these activities, the researchers measured the participants’ blood glucose levels. The results were remarkable. Those who had laughed during the comedy show had significantly lower post-meal blood glucose levels compared to those who attended the boring lecture.
This study suggests that laughter not only lifts our spirits but also has a tangible, positive effect on our body’s metabolic processes. While the mechanisms behind this phenomenon are still being studied, it’s clear that humor can alter physiological responses, potentially through the regulation of stress hormones like cortisol.
Epigenetics: How Positive Emotions Can Change Our Biology
This study’s findings align with growing research in the field of epigenetics, which explores how environmental factors and behaviors can influence gene expression. Positive emotions, especially those linked with humor and laughter, may reduce the production of stress-related chemicals and promote a cascade of beneficial biological processes. In this way, humor doesn’t just make us feel better—it may literally change how our genes express themselves.
Positive Thinking vs. Positive Emotion
It’s important to differentiate between positive thinking and positive emotion. While both are beneficial, they are not synonymous. Positive thinking alone may not be enough to trigger the biological changes necessary for healing. It’s the emotional experience—feeling joy, humor, or gratitude—that seems to catalyze physiological shifts. Laughter embodies this principle by generating genuine positive emotion rather than just the intention of positivity.
Integrating Humor into Healing
For therapists, coaches, and anyone invested in well-being, integrating humor into daily life or treatment plans could yield both psychological and physical benefits. Whether through light-hearted conversations, comedy shows, or playful interactions, creating space for laughter can support holistic healing practices.
A Call to Action: Laugh More, Heal More
The power of humor to influence our health isn’t just theoretical; it’s backed by scientific evidence and aligns with modern understandings of mind-body connections. As we continue to explore the role of positive emotion in healing, laughter may prove to be one of the most accessible and enjoyable therapies we have.
So, next time you feel overwhelmed, stressed, or even physically unwell, consider allowing yourself a good laugh. It might just be the medicine your body—and mind—needs.

A Simple Way to Track Your Healing Between Sessions
Healing does not only happen in the therapy room. Often, the shifts you are making show up in small, everyday moments that are easy to overlook.
The EMDR Therapy Progress Journal is designed to help you gently track those changes. It gives you space to reflect on your thoughts, emotions, and patterns in a way that feels structured but not overwhelming.
Many clients find that writing things down helps them:
Notice progress they might otherwise miss
Stay connected to what they are working on in therapy
Better understand their triggers, responses, and growth over time
This is not about doing therapy “perfectly.” It is about creating a space to stay curious about your experience and support your healing at your own pace.
If you are looking for a simple way to stay grounded between sessions, this can be a helpful addition to your therapy work.
