Why Laughing Really Is the Best Medicine: How Humor Heals Your Brain, Body, and Relationships

Have you ever felt guilty for laughing during a hard time? Or noticed how a good laugh with a friend made you feel more grounded, less anxious, and even physically lighter?

Laughter is often dismissed as a distraction or indulgence, especially in the midst of stress, trauma, or grief. But neuroscience tells a different story. Laughter is not just a temporary mood booster. It activates critical pathways in the brain, regulates the nervous system, supports immune function, and deepens relational connection. In a world where stress, disconnection, and emotional overwhelm are at all-time highs, understanding the mental and physical health benefits of laughter can be a powerful step toward resilience and renewal.

At Embodied Wellness and Recovery, we work with clients navigating trauma, relationship challenges, sexuality, and intimacy issues. Many arrive feeling disconnected from joy, believing laughter is out of reach. But humor, like other forms of embodied expression, can be a pathway back to aliveness.

The Neuroscience of Laughter: What Happens in Your Brain and Body

Laughter is a full-body experience. It activates multiple regions of the brain, including the prefrontal cortex, limbic system, and hypothalamus. These regions coordinate emotional processing, decision-making, memory, and stress response.

When you laugh, your brain releases a cocktail of neurochemicals:

     — Dopamine, which boosts motivation and pleasure
    — Endorphins, which reduce pain and promote a sense of well-being
     — Oxytocin, often called the “bonding hormone,” which increases trust and social connection
     — Serotonin, which stabilizes mood

According to research, even simulated laughter can trigger the same neurochemical release as genuine laughter (Holt-Lunstad et al., 2008). The act of laughing increases oxygen intake, stimulates the heart and lungs, and activates the parasympathetic nervous system, which is responsible for rest and digestion.

In short, laughter helps regulate your autonomic nervous system, shifting you out of fight-or-flight and into a state of safety and calm.

Laughter as a Tool for Mental Health

Mental health challenges often leave people feeling stuck in a loop of worry, rumination, or emotional numbness. Laughter disrupts that loop. It restores spontaneity, encourages flexibility, and allows the nervous system to reset.

Common mental health struggles that laughter can help support:

     — Anxiety: Laughter lowers cortisol levels, the hormone associated with stress and anxiety. It helps reduce muscle tension and shifts focus from future-oriented fear to present-moment awareness.
    — Depression: Laughter stimulates the release of neurotransmitters that elevate mood. In group settings, shared laughter can offer a sense of belonging that counters depressive isolation.
    — Trauma: While trauma work must be done thoughtfully and with care, laughter can be a valuable counterbalance to heaviness. It provides emotional contrast and invites clients into an embodied experience of lightness.

Importantly, laughter is not a replacement for trauma-informed therapy, but it can be a valuable somatic resource that supports nervous system resilience.

Physical Health Benefits of Laughter

Laughter does not just feel good. It actually supports the body’s biological systems in tangible, measurable ways.

1. Boosts immune function

Laughter increases the production of antibodies and activates immune cells like T-cells and natural killer cells, improving the body’s ability to fight illness (Bennett et al., 2003).

2. Reduces pain

Endorphins released during laughter act as natural painkillers. In fact, some studies have shown that people watching comedy videos experience higher pain thresholds afterward.

3. Protects cardiovascular health

Laughter improves blood flow, enhances endothelial function, and reduces blood pressure. These changes support heart health and reduce the risk of cardiovascular disease.

4. Improves sleep

Laughing before bed can help reduce stress hormones and promote deeper, more restful sleep. It lowers physiological arousal and invites the body into a state of relaxation.

Laughter, Connection, and Intimacy

At its core, laughter is a relational experience. It often arises in the presence of others and helps to deepen connection. Couples who laugh together report greater relationship satisfaction and emotional intimacy. Shared laughter acts as a form of co-regulation, allowing partners to synchronize their nervous systems and return to a state of connection after conflict.

In the context of therapy, laughter can be an entry point into vulnerability. Clients who feel stuck in patterns of emotional shutdown or hypervigilance often find that laughter offers relief from shame and a bridge to re-engagement.

Laughter also plays a significant role in sexual intimacy. Humor lowers defenses and increases comfort, which is essential when navigating body image issues, performance anxiety, or past sexual trauma. A sense of playfulness can enhance communication and reduce tension around vulnerability.

Why So Many People Feel Disconnected from Joy

If laughter is so beneficial, why is it often so difficult to access?

For many people, especially those with a history of trauma or high-functioning anxiety,  joy feels unsafe. The nervous system may interpret laughter as a loss of control. Others may have grown up in environments where humor was weaponized or not allowed, leading to an internalized belief that joy is not permitted or deserved.

This is why a somatic and trauma-informed lens is essential. At Embodied Wellness and Recovery, we help clients reestablish a felt sense of safety in their bodies so that joy, pleasure, and laughter can be experienced as nourishing rather than threatening.

Bringing Laughter Back into Your Life

If you’ve been feeling disconnected from joy, know that laughter is something you can cultivate. It may feel awkward at first, especially if your body has been in a chronic state of survival. But small, intentional shifts can open the door.

Try one of these practices:

     — Watch a favorite comedy show or stand-up special
    — Join a laughter yoga or improv group
    — Engage in playful movement like dance or silly walks
     — Spend time with animals or young children
    — Practice “fake laughing” for 30 seconds and notice how it shifts your state
    — Recall a memory that once made you laugh and replay it in your mind

You do not have to force joy, but you can create space for it to return.

Laughter as an Invitation to Wholeness

True healing does not only happen through tears. It also happens through joy, play, and shared delight. Laughter reminds us that even in the midst of hardship, we are still wired for connection, creativity, and pleasure.
