Why Does Your Stomach Hurt When You Laugh Really Hard?

Your stomach hurts from laughing too hard because of the contraction of different abdominal and respiratory muscles that are activated when you laugh.

A robust and hearty laugh (whether from a corny joke, an adept comedian, or the everyday absurdity of life) can make it feel like you’ve been running around the block! You may run out of breath and your heart rate increases. However, it also has the peculiar ability to make your stomach hurt, a rather unpleasant side effect of intense laughter.

What triggers this sensation? As it turns out, the explanation lies in the intricate interplay of various muscles involved in the mechanics of laughter. Let’s delve deeper to figure out how that happens.

Laughter, A Dynamic Act

Laughter is a remarkably dynamic and uncontrollable action. Attempting to remain still and stoic while engulfed in laughter is a futile endeavor. If you’ve ever tried, you know it’s impossible. When you laugh, the muscles around your eyes and cheeks contract, making your face come alive with a range of amusing expressions. To top it off, laughter makes you emit strange sounds, a symphony of “HA HA” and “HE HE”. If you were unfamiliar with the sight of someone in the throes of laughter, it would sound nothing short of absurd.

The Mechanics Of Laughter – Muscle Contractions And Abdominal Discomfort

We can break down the mechanics of laughter into two primary components: the visible movements in the trunk region and the signature sounds we all recognize: HA HA, HE HE, HO HO etc. The two components are interlinked.

When we laugh, we exhale vigorously. The exhaled air whooshes out through the windpipe, exerting pressure on the voice box (larynx) as it leaves. This, in turn, makes the vocal cords vibrate and produce the characteristic ‘ha ha” sounds of laughter.

The intensity of exhalation is connected to muscle contractions in the trunk region. As you laugh, the abdominal muscles contract, which reduces the volume in the lungs. This drop elevates pressure around the lungs, resulting in increased expiratory output.

These forceful exhalations are a significant factor contributing to the discomfort you feel in the stomach during intense bouts of laughter. As the abdominal muscles engage, they exert pressure on the diaphragm and internal intercostal muscles, leading to diaphragmatic contractions that impact surrounding abdominal organs, causing pain or discomfort.

Laughter Yoga Study: Insights From Scientific Exploration

The fact that laughter imposes a physical demand on the trunk muscles has been scientifically verified. To substantiate this, scientists conducted a study comparing the activation of trunk muscles during laughter yoga to traditional back-lifting exercises and crunches. The results of the study were quite interesting.

The scientists found that a set of abdominal muscles situated on the lateral side (the internal obliques) showed more activation during laughter yoga as compared to their engagement in traditional exercises.

Another set of abdominal muscles stretching from the lower ribs down to the pelvis (the external obliques) showcased an activation level that mirrored the intensity witnessed during crunches and back-lifting exercises. Muscles like the multifidus, erector spinae, and rectus abdominis showed half as much activation during laughter as compared to crunches.

Considering the findings of the study, it’s only fair to say that laughter can be an excellent form of abdominal exercise, sparing you the monotony of conventional exercises. Therefore, embracing a bit of discomfort during this aerobic laughter workout can yield significant benefits. It’s crucial to remember that, since the demand on your trunk muscles concludes with laughter, any fleeting discomfort is usually harmless and temporary. Nevertheless, it’s important to remember that certain conditions could potentially turn this discomfort into a more significant health concern.

Why Does It Hurt In My Side Or Lower Stomach?

Many people notice the ache is not spread evenly across the belly. It often settles in one place: low down in the lower abdomen, off to one side, or in the flanks just under the ribs. This is simply a matter of which muscles are doing the most work, and where they sit.

Your abdominal wall is built from a few overlapping sheets of muscle. The rectus abdominis (the “six-pack” muscle) runs straight down the front from the lower ribs to the pelvis, so when it fatigues you tend to feel it in the middle and toward the lower stomach. The external and internal obliques wrap diagonally around your sides, which is why a long fit of giggles so often leaves a stitch-like soreness in the flanks rather than dead-center. According to the StatPearls anatomy reference, all of these muscles squeeze the belly inward to assist forceful exhalation and to raise the pressure inside the abdomen during actions like coughing, and a hearty laugh is exactly that, over and over.

The other usual suspect is the diaphragm, the dome of muscle beneath your lungs. Each “ha” forces it to spasm rhythmically, and that quick, repeated contraction can register as a pinch or ache higher up, just below the ribs. None of this is cause for alarm on its own: pain that tracks your breathing, eases within a few minutes of calming down, and is not tied to a fever, swelling, or a tender lump is almost always tired muscle rather than anything inside the abdomen. A sharp, one-sided pain that keeps building after the laughing stops is the exception worth getting checked, as we cover below.

Is There Such A Thing As Too Much Laughter?

Laughing is good for you, but laughing too much and too hard could be very bad for you.

One reported health risk from intense laughing is the potential to worsen a pre-existing hernia. A hernia develops when an organ protrudes out of the muscle or tissue containing it. They are commonly found in the abdominal region, where parts of your bowels can poke out through holes or weaker regions in the abdominal walls. The trunk compression from intense laughter could lead to strangulation of the hernia, cutting off blood supply and causing intense pain.

However, such cases are less frequent and almost any intense physical activity could pose a danger or risk, including regular workouts. In other words, don’t let these rare cases become a laughter buzzkill. After all, the benefits of laughter far outweigh the risks.

Why Are My Abs Sore The Next Day, And Can Laughing Give You Abs?

Sometimes the ache does not show up during the laughing fit at all. Instead you wake up the next morning with stiff, tender abs, as though you had done a round of crunches. If that sounds familiar, you have met delayed onset muscle soreness, or DOMS, the same dull soreness people feel a day or two after an unfamiliar workout.

DOMS is thought to come from tiny, harmless tears in muscle fibers that are worked harder than they are used to, and it is most pronounced when a muscle contracts while being stretched. A really violent belly laugh asks your abs to fire dozens of rapid contractions in a row, which is plenty to leave them sore if you are not used to it. As the Cleveland Clinic notes, this kind of soreness typically starts one to three days after the effort, peaks somewhere in the 24 to 72 hour window, and fades on its own within a few days. Gentle movement, warmth, and staying hydrated tend to help it along, while there is nothing you actually need to “treat”.

So can you genuinely get abs from laughing? Not in the gym-trophy sense. The muscle work is real, and as we will see it does burn a few calories, but visible abs depend far more on overall body fat than on any single movement. Think of a good laugh as a pleasant bonus for your core rather than a substitute for exercise. The soreness is proof your obliques and rectus abdominis put in a shift, not a sign that a six-pack is on the way.

Laugh Your Way To Firm Abs!

Did you know that you can put your laughter to work and burn a few calories at the same time? Laughing heartily for 10-15 minutes can burn approximately 10-40 kilojoules (about 2-10 calories). It can serve as a delightful aerobic exercise that works out your respiratory and abdominal muscles.

Researchers also suggest that laughter isn’t just good for a chuckle; it can also play a role in complementing physiotherapy and rehabilitation. Particularly in cases where traditional exercises might be a challenge, the activation of both local and global trunk muscles during laughter can lend a stabilizing hand to your spine, giving your recovery process a unique boost.

The bottom line? Laugh your heart out, knowing that with every laugh, you’re not just sharing pleasure, but also giving your body a lighthearted workout!
