Stop me if you’ve heard this one.

What do you give a man who has everything?
Penicillin.

Did you laugh?

How about this one…

How do you make an egg roll?
You push it.

A chuckle? At least a smirk?

The Positive Effects of Laughter

Did you know that laughter can have a measurable impact on your immune system function? You’ve probably heard the old adage: “Laughter is the best medicine.” Well, it turns out that this may be very true. More and more studies are showing the positive effects of laughter in multiple aspects of health and wellbeing.1,2

​​​While many studies talk about the psychological (mental) benefits of laughter3, a few also make a link to physiological (health) benefits as well. Laughter can lower cortisol and other stress hormone levels.4,5,6 These stress hormones are known to suppress immune system function.

Science has known for a long time that high levels of stress, whether mental, physical, or emotional, can reduce immune function. Prolonged stress will also have a negative effect on other aspects of your health. Laughter helps offset or reduce the effects of prolonged stress on various systems in the body.

The Immune System Benefits of Laughter

Laughter impacts several aspects of immune function. Laughter increased levels of secretory IgA, key antibodies in your body’s defenses, and NK cell activity, important first responder immune cells.7,8,9,10 There’s even some indication that laughter might help with allergies.11 These studies show some rather broad effects on immune function. It’s not just one area or one cell type.

What’s more, laughter’s effects on the immune system were shown to last for up to 12 hours after a single laughing--session.12 In other words, a couple good sessions of laughter may have you covered all day long. Take some 4Life Transfer Factor with your laughter and you’re potentially increasing the immune benefits.*

Get Healthier: Laugh More!

As you can see, there are many benefits of a couple chuckles each day. No matter how difficult life becomes, take time to put some laughter in each day. Your body, mind, and immune system will thank you.


Here’s a little something to get you started:

Two hunters are out in the woods when one of them collapses. He’s not breathing, and his eyes are empty. The other guy whips out his phone and calls 911.

“I think my friend is dead,” he yells.

“What should I do?”

The operator says, “Calm down. First, let’s make sure he’s really dead.”

There’s silence, then a shot. Back on the phone the guy says, “Okay, now what?”



Can you feel the immune benefits yet? Now…how do we fit laughter into a capsule? 💊
