Could Laughter Be An Essential “Nutrient” for Reversing Disease and Living Longer?

Originally written for the Epoch Times.

Imagine walking into your doctor’s office, expecting another prescription, only to have them hand you a slip that says: “Watch a comedy show daily.” Far-fetched? Maybe. But science suggests there’s truth in the old saying, “Laughter is the best medicine.” 

Turns out, laughing isn’t just a feel-good bonus.  It’s a powerful wellness tool that boosts immunity, reduces stress, and even helps the body fight cancer cells. 

And the best part? It’s free! If you’re looking for a side-effect-free health boost, maybe it’s time to start viewing laughter as an essential nutrient.

The Science of Laughter: A Natural Health Elixir

Research reveals that laughter triggers measurable, health-enhancing changes throughout the body. For starters, laughter has been shown to decrease pro-inflammatory cytokines, making it an ally in lowering chronic inflammation, which is a factor involved in every chronic health condition from diabetes to heart disease. With each laugh, you’re dialing down inflammation, an essential step in disease prevention and reversal.

For those managing conditions like Type 2 diabetes, laughter can lower blood glucose levels and delay cardiovascular complications, according to a review in Diabetes Research and Clinical Practice. The researchers suggested laughter “should be used as an adjuvant therapy” for diabetic patients.

Laughter also works wonders for lowering blood pressure and elevating mood by reducing stress hormones like cortisol and adrenaline, helping the body transition from tense to relaxed. When cortisol and adrenaline run high, our bodies stay in “fight or flight” mode, which wears down physical health over time. A hearty laugh counteracts this, improving mood and melting away stress.

Laughter even kills cancer cells. It boosts natural killer cell activity which are immune cells responsible for targeting and destroying sick or stressed cells, including cancer cells. The harder you laugh, the more these microscopic warriors get activated. Research shows that laughter can keep these cells engaged for up to 12 hours! It’s like flipping on the Bat Signal for your immune system—summoning its strongest defenders to patrol your body for hours after the joke is over.

Additionally, laughter enhances memory, especially in older adults. A 2015 study found that when diabetic seniors watched a humorous video for 20 minutes, their learning ability and delayed recall significantly improved, along with a drop in cortisol levels. Researchers concluded that laughter has “clinical benefits” in wellness programs aimed at older adults, particularly for cognitive health.

Laughter also strengthens immunity. A 2001 study in Alternative Therapies in Health and Medicine showed that watching a humor video for an hour improved immune markers, including T cells and B cells, which fight off acute infections. Levels of immunoglobulin A, an antibody crucial for immune health and autoimmune disease prevention, also rose. The researchers concluded that laughter could be an effective part of wellness programs.

Laughter as Part of the Daily Routine

Some families start their day with vitamins.  We start with laughter. Every morning, my family shares a few jokes, from the classics (Why did the mushroom get invited to all the parties? Because he’s a fungi!) to the groan-worthy (What do you get when you pamper a cow?  Spoiled milk.). 

These moments lift our spirits, help us connect, set a joyful tone for the day, and give our immune systems a little boost. By prioritizing laughter each day, I teach my children that laughter is a critical part of a daily wellness routine that is as essential as a vitamin. 

How to Get Your Daily Dose of Laughter

If the idea of intentional laughter seems odd, try these tips to make it feel natural and, yes, a little bit contagious:

1. Start Your Day with Laughter: Kickstart your morning with a comic, funny video, or joke. My family loves flipping through books containing “dad jokes” each morning. It’s an easy way to start the day on a high note without reaching for screens first thing, and it keeps the giggles going.

2. Share the Joy: Laughter is 30 times more likely to happen in social settings than when you’re alone, according to researchers at the University of Maryland. So, create more opportunities for shared laughter.  Read a comic with your kids, play a silly game with your grandchildren, send a funny meme to a friend, swap goofy stories with coworkers, or queue up a comedy night with loved ones. Let laughter bring you together. 

3. Try Laughing Yoga: This practice combines yoga breathing with sustained laughter exercises. Inhale deeply, and exhale with a big, hearty laugh. Even if you begin with forced laughter, before you know it, the real thing often takes over! Every time I’ve introduced laughing yoga to my kids or clients, they end up genuinely laughing.  Maybe they laugh from feeling silly, but it still does the trick!

4. Revisit Your Favorite Funny Memories
Laughter isn’t just about the present.  It can come from reliving a hilarious past moment. Keep a 'laughter file' with funny texts, inside jokes, or silly memories, and revisit them when you need a boost. Even better? Share them with the people who were there. It’s like hitting replay on joy!

5. Curate a Laughter Playlist
Just like you might have a playlist for workouts or relaxation, why not create one for laughter? Fill it with stand-up comedy clips, blooper reels, or TV show highlights that always crack you up. A few minutes of laughter on demand can shift your mood–and your health–instantly.

A Prescription for Joy

In a world where stress seems to lurk around every corner, laughter might be the missing nutrient we need. Imagine that every time you laugh, you’re not just lightening your mental load; you’re boosting your immune system, reducing inflammation, and, quite possibly, adding years to your life. 

So, go ahead.  Get your daily dose of laughter. No copay required, and it might help keep you feeling young.
