Queefing is completely normal, and if it feels like it happens to you a lot, you’re far from alone. Studies estimate that anywhere from 25% to 70% of women experience vaginal gas, with sexually active and younger women reporting it most often. It’s not a sign that something is wrong with your body. Air gets into the vaginal canal, and then it comes back out, sometimes with a sound. That’s the entire process.
How Air Gets Trapped in the First Place
The vaginal canal is a flexible, muscular tube, not a sealed chamber. Anything that opens or changes the shape of the canal can let air slip inside. Once that air is in there, normal movement, muscle contractions, or a change in position pushes it back out, producing the sound. Unlike intestinal gas, queefing has no connection to digestion and carries no odor (unless there’s something else going on, which we’ll cover below).
The most common ways air enters the vagina include penetrative sex, inserting or removing tampons and menstrual cups, certain exercises, and even just shifting your body position. Essentially, anything that creates a temporary opening or changes internal pressure can introduce air.
Sex Is the Most Common Trigger
Among women who experience vaginal gas, nearly half report it happening often or always during sexual activity. That makes sex the single biggest trigger. During penetration, a penis, toy, or fingers can act like a piston, pushing air into the vaginal canal with each thrust. When penetration stops or when you shift positions, that trapped air escapes.
Certain positions make this much more likely. Doggy style and any position where your hips are elevated above your torso, or where your body is curled into something resembling a fetal position, forces air into the vaginal canal. If queefing during sex bothers you, switching to positions where your torso stays more upright can reduce how much air gets pushed in. Face-to-face positions with less dramatic angles tend to trap less air.
Exercise and Yoga Are Frequent Culprits
If you’ve ever queefed in a yoga class, you already know this one. Inverted poses like downward dog, bridge, and shoulder stand open the vaginal canal in a way that lets air flow in. When you transition to the next pose and engage your core, that air gets squeezed right back out. Pilates causes the same thing for the same reason: core engagement combined with hip-opening or inverted positions.
Running, squats, and other exercises that involve repetitive changes in abdominal pressure can also do it, though yoga and Pilates are by far the most commonly reported triggers outside of sex. About 12% of women who experience vaginal gas say it happens during exercise.
Pelvic Floor Strength Plays a Role
Your pelvic floor muscles act like a hammock supporting your bladder, uterus, and vaginal canal. When these muscles are strong, they help keep the vaginal walls closer together, making it harder for air to enter. When they’re weakened, the canal is more relaxed and open, which means air slips in more easily and exits more noticeably.
Several things weaken pelvic floor muscles over time. Pregnancy and vaginal childbirth are major ones. The strain of carrying a baby and delivering it stretches and sometimes injures these muscles. Menopause is another factor, as declining estrogen levels cause the tissues to lose some of their tone and elasticity. Chronic heavy lifting, obesity, and aging in general also contribute. If you’ve noticed queefing becoming more frequent after having a baby or as you’ve gotten older, weakened pelvic floor muscles are the most likely explanation.
Strengthening Your Pelvic Floor
Kegel exercises are the most straightforward way to build pelvic floor strength. The basic technique: tighten the muscles you’d use to stop the flow of urine midstream, hold for three seconds, then relax for three seconds. That’s one repetition. Aim for a set of 10, twice a day (morning and evening). If 10 feels difficult at first, start with five. Over time, work up to holding each squeeze for five seconds.
You can do Kegels lying down, sitting, or standing. If your muscles feel very weak, starting while lying down makes it easier to isolate the right muscles. Consistency matters more than intensity here. Most people notice a difference after several weeks of daily practice. If you’re not sure you’re targeting the right muscles, or if you have other pelvic floor symptoms like bladder leakage, a pelvic floor physical therapist can guide you through a more targeted program.
When It Might Signal Something Else
In the vast majority of cases, queefing is harmless. The only “symptoms” are the sound and the sensation of air leaving, both painless. There’s no treatment needed and, honestly, no reliable way to prevent it entirely.
The rare exception is a vaginal fistula, an abnormal connection between the vagina and another organ like the bladder or bowel. Fistulas can develop after childbirth injuries, surgery, or radiation treatment. The key difference: a fistula causes symptoms that go well beyond a simple air sound. Signs include leaking urine or stool through the vagina, foul-smelling or unusual vaginal discharge, frequent urinary tract infections, and pain during sex or in the area between the vagina and anus. If your vaginal gas carries a noticeable odor or comes with any of these other symptoms, that warrants a medical evaluation. If it’s just the sound and air, it’s not a medical issue.
Why It Might Be Happening More Lately
If you feel like queefing has increased recently, think about what’s changed. A new sexual partner or new positions can introduce more air than you’re used to. Starting yoga, Pilates, or a new workout routine is another common trigger. Postpartum recovery, perimenopause, or menopause can shift your baseline because of the pelvic floor changes they bring. Even something as simple as switching from pads to tampons or menstrual cups means you’re introducing an object into the canal more regularly, which pushes air in.
None of these scenarios are cause for concern. Your body isn’t broken or abnormal. The vaginal canal is designed to expand and contract, and that flexibility means air will sometimes get involved. Pelvic floor exercises can reduce the frequency, and adjusting sex positions or being mindful of transitions during yoga can help too, but some amount of queefing is just part of having a vagina.
