Leaking urine when laughing: why it happens and what helps
Leaking a little when you laugh is usually stress incontinence: each laugh squeezes your belly and pushes down on your bladder, and if the pelvic floor and the muscle around the urethra can't close fast and hard enough, a little urine gets out. It's common, especially after childbirth and around menopause, and pelvic floor training is the first treatment guidelines recommend.
Laughter is harder to guard against than a cough or a sneeze, though, because you can't see it coming and it goes on for several seconds. This guide explains why, how to train for it, what to do in the moment, and when a leak while laughing points to something else.
Why do I pee when I laugh?
When you laugh, the muscles of your belly and diaphragm push in sharp bursts. Pressure inside your belly rises with each one, and that pressure presses on your bladder. Normally your pelvic floor tightens a split second before, and the urethra stays shut. If the floor is weaker, slower, or its support has stretched, the pressure wins for a moment and a few drops or a small spurt escape.
Common reasons the floor loses that contest:
- Pregnancy and vaginal birth, which stretch the muscles and the tissue that holds up the urethra.
- Menopause. Falling estrogen changes the tissue of the urethra and vagina; many women first notice leaks in the transition. See perimenopause incontinence.
- Age. Muscle strength falls with age everywhere in the body, including here.
- Extra weight, which adds steady pressure on the bladder.
- A long-term cough or constipation, which push down on the floor many times a day.
- Past pelvic surgery, such as a hysterectomy.
Why laughing is harder than sneezing
| Sneeze or cough | Laugh | |
|---|---|---|
| Warning | Usually a second or two: the tickle, the in-breath | Often none; it starts as the joke lands |
| Length | One burst | Many bursts over several seconds, sometimes a minute |
| What it asks of the floor | One strong, well-timed squeeze | A squeeze you can hold, while breathing, through repeated pushes |
| Main training | The Knack: a squeeze just before | The Knack plus endurance: longer holds and repeated quick squeezes |
That's why some women who have stopped leaking on sneezes still leak on a big laugh. The quick squeeze solves the first push; the laugh then keeps pushing after the squeeze has faded. Training for laughter means building a hold you can keep for 10 seconds while breathing and talking, and quick squeezes you can repeat.
Is it stress incontinence, or something else?
| What happens | Likely type |
|---|---|
| A few drops or a small spurt on a laugh, cough, sneeze or lift; stops when the laugh stops | Stress incontinence (the usual case) |
| A laugh sets off a strong urge, then you can't hold it | Urge incontinence, or mixed |
| Leaks on laughing plus sudden urges at other times | Mixed incontinence |
| A laugh empties the whole bladder, in a child or teenager | Giggle incontinence (rare; see below) |
| Constant dribbling, or a bladder that never feels empty | Something else: see a doctor |
A three-day tally helps: each leak, what set it off, and roughly how much. Our free 1-minute check also asks when your leaks happen.
What is giggle incontinence?
"Giggle incontinence" is a different, rare condition. It mainly affects children, especially girls aged about 7 to 14, and it usually means a large leak that can empty the bladder completely during or right after laughing. The cause isn't known; one theory is that laughter sets off the bladder muscle itself. Most children grow out of it, and it's quite rare in adults. If this sounds like you or your child, see a doctor: it's treated differently from adult stress leaks. The rest of this guide is about the common adult kind.
How to stop leaking when you laugh: the exercises
Slow holds, built to 10 seconds
Lie on your back, knees bent. Breathe out and lift the pelvic floor up and in, as if stopping wind and the flow of urine at once. Keep breathing. Hold as long as you can at full strength, then let go fully and rest as long. 8 to 12 holds, 3 times a day. Start where you are (often 3 to 5 seconds) and add a second every week or two until you reach 10. This is the hold that has to last through a laugh.
Quick squeezes, in a row
A strong 1-second lift, a full let-go, and again. 10 in a row after each set of holds. For laughter, train repeated quick squeezes, because a laugh pushes again and again.
Holds while talking
Once you can hold for 6 to 8 seconds lying down, practise holding while sitting and talking: count out loud, or read a sentence aloud, while holding the lift. Laughing uses your breath; your floor has to hold while your breath moves.
Practice laughs
This sounds odd, but it works the way practice coughs do. Standing, with an empty bladder, lift the pelvic floor, then give 3 or 4 short "ha ha ha" pushes out loud while keeping the lift. Let go. 5 times, once a day, from week 3 or 4. It trains the exact pattern of a laugh.
For a whole programme, sets and reps for every leak type, see our guide to pelvic floor exercises for incontinence. For finding the muscle and checking you lift rather than push, see how to do Kegels correctly.
What to do in the moment
- Squeeze at the first sign. As soon as you feel a laugh coming, lift the floor. In a 1998 study of the squeeze-before-the-cough (the Knack), selected women with mild leaks cut cough leakage by 98% on average within a week. A laugh is harder to time, but the same reflex helps.
- Cross your legs or press your thighs together. It gives the urethra a little outside support while your floor works.
- Lean forward slightly rather than throwing your head back. Leaning back opens the belly and puts more push on the bladder.
- Breathe out, not in-and-hold. Holding your breath and bracing adds pressure on the floor.
- Empty your bladder before a film, a night out or time with the friend who always makes you laugh. A fuller bladder leaks more easily. Don't make a habit of going "just in case" all day, though; that trains the bladder to hold less.
A 12-week plan for laughing leaks
| Weeks | Every day | Goal by the end |
|---|---|---|
| 1–2 | 3 sets lying down: 8 slow holds (3–5 s) + 10 quick. The squeeze before every cough or sneeze. | A clean lift and let-go, no breath holding |
| 3–4 | 3 sets, lying or sitting: 8–10 holds (5 s) + 10 quick. Start practice laughs × 5. | Hold through 3 "ha"s |
| 5–8 | 3 sets sitting or standing: 10 holds (6–8 s) + 10 quick. Holds while counting aloud. | Hold for 8 seconds while talking |
| 9–12 | 3 sets standing: 10–12 holds (8–10 s) + 10 quick. Practice laughs standing. | Fewer leaks on real laughs (check your tally) |
| After 12 | 1 set a day or 3–4 a week; squeeze at the first sign of a laugh, sneeze or lift | Keep what you built |
Cleveland Clinic puts first changes from daily training at about 6 to 8 weeks; NICE asks for at least 3 months of training before judging. See how long Kegels take to work for what changes when, and leaking when you sneeze or cough and leaking when running for the other common triggers.
Other things that help
- Less caffeine, which NICE recommends trying for an overactive bladder; some women find fizzy drinks and alcohol make leaks worse too.
- Normal fluids. Drinking less makes urine stronger and can irritate the bladder.
- Weight, if your BMI is over 30: NICE advises that losing weight can help.
- Treat constipation and a long-term cough, which tire the floor.
- Pads made for urine, not period pads, while you train. They hold more and keep skin drier.
Is leaking when you laugh normal?
It's common, but you don't have to live with it. Stress incontinence is the most common type of leak in women, and it often starts after children or around menopause. Many women put up with it for years before telling anyone. Because pelvic floor training works for so many women with stress leaks (in a 2018 Cochrane review, 56% of women who trained reported being cured against 6% who didn't), it's worth a proper 3-month try.
When to see a doctor
See a doctor if you have blood in your urine, pain or burning, fever, a bulge or heaviness in the vagina, trouble emptying, constant dribbling, or if a laugh empties your whole bladder. See a doctor or a pelvic floor physical therapist too if you've trained well for 3 months and nothing has changed. They can check your squeeze, and talk about other options: a vaginal device or pessary that supports the urethra, vaginal estrogen after menopause, or surgery for stress leaks that don't respond.
Frequently asked questions
Why do I pee a little when I laugh?
Laughing raises the pressure in your belly. If the pelvic floor can't close the urethra fast and long enough, a little urine escapes. This is stress incontinence.
Can you stop leaking when you laugh?
Many women can, with daily pelvic floor training for at least 3 months plus the squeeze at the first sign of a laugh. It doesn't work for everyone, and a doctor can offer other options.
Why do I leak when I laugh but not when I sneeze?
A sneeze is one push you can see coming. A laugh is many pushes, often without warning, so it needs a hold that lasts as well as a fast squeeze.
Is leaking when laughing a sign of a weak pelvic floor?
Usually, yes, or a floor whose support has stretched. Less often it's a floor that's tight and tired. If you also have pain or trouble emptying, read tight pelvic floor symptoms.
Does leaking when laughing get worse with menopause?
It can, because falling estrogen changes the tissue around the urethra. Training still helps at any age. See bladder leakage and menopause.
Where to start today
Today, time one slow hold lying down and write it down; that's the number you'll build to 10. Next time you feel a laugh coming, lift first. If you'd like to see in one minute why Kegels often don't help on their own, take the free 1-minute check. For more on leaks, urges and the pelvic floor after 40, see all our pelvic floor guides.
