Laughing is good for pregnancy. It triggers the release of endorphins, your body’s natural feel-good chemicals, which improve mood and reduce the physical effects of stress. For both you and your baby, those benefits are meaningful during a time when hormonal shifts can make stress and anxiety feel amplified.
How Laughter Affects Your Body During Pregnancy
When you laugh, your brain releases endorphins and serotonin, two chemicals that promote relaxation and elevate mood. At the same time, laughter lowers levels of stress hormones like cortisol and adrenaline. This matters during pregnancy because chronically elevated stress hormones can affect sleep, blood pressure, and overall comfort. A good laugh essentially gives your nervous system a brief reset, shifting you out of a stress response and into a more relaxed state.
Laughter also increases blood flow and oxygen intake. The deep breathing involved in a real belly laugh pulls more air into your lungs than shallow, everyday breathing. This boost in circulation benefits both you and your baby, since the placenta relies on your blood supply to deliver oxygen and nutrients.
What Your Baby Experiences When You Laugh
Your baby can feel it when you laugh. Ultrasound observations have captured babies bouncing gently inside the womb during a mother’s laughter. Jenna Hopkins, a registered diagnostic medical sonographer, has explained that the movement laughter creates rocks the baby in the womb, and that babies can likely feel the vibrations. While that bouncing might look dramatic on screen, the amniotic fluid and surrounding padding keep the baby well-cushioned and safe.
Beyond the physical rocking, the serotonin released during laughter reaches your baby through the placenta. This is thought to help them feel calm and comfortable. So when you’re genuinely enjoying yourself, your baby is sharing in some of that biochemical benefit.
Laughter and Prenatal Mental Health
Depression and anxiety during pregnancy are common, affecting roughly 1 in 7 women. Laughter won’t replace professional treatment for clinical depression, but research supports it as a meaningful complementary tool. A randomized controlled study of 104 women found that laughter yoga, a structured practice combining laughter exercises with deep breathing, significantly reduced depression symptoms after just six sessions, as measured by the Edinburgh Postpartum Depression Scale.
Separate research on laughter yoga during pregnancy found improvements in mental well-being, reduction in pregnancy-related symptoms like fatigue and discomfort, and stronger prenatal attachment, the emotional bond a mother feels with her baby before birth. These aren’t small, subjective impressions. They showed up as statistically significant differences between groups who practiced laughter yoga and those who didn’t.
What makes laughter particularly useful is that it’s accessible. You don’t need equipment, a prescription, or even a reason. Watching a funny show, spending time with people who make you laugh, or trying a laughter yoga class all count. The key is that the laughter is genuine and sustained enough to trigger that endorphin release.
One Practical Side Effect to Manage
There is one less glamorous reality: laughing during pregnancy can make you leak urine. Stress urinary incontinence is the most common type of bladder control issue during pregnancy, and it’s triggered by exactly the kind of sudden abdominal pressure that comes with laughing, along with coughing and sneezing. The growing uterus puts pressure on your bladder, and pregnancy hormones relax the pelvic floor muscles that normally help you hold urine in.
This is manageable. Kegel exercises, where you squeeze and release the muscles you’d use to stop your urine midstream, strengthen the pelvic floor over time. Doing them consistently throughout pregnancy helps reduce leakage. Planning bathroom breaks before situations where you know you’ll be laughing (movie night, dinner with friends) also helps. Wearing a light pad on days when you’re feeling more pressure can take the worry out of it entirely. None of this should discourage you from laughing. It’s just a practical consideration worth planning around.
How to Get More Laughter Into Your Day
If laughter doesn’t come naturally right now, that’s completely normal. Pregnancy fatigue, nausea, and anxiety can flatten your mood. A few approaches can help. Laughter yoga classes, available both in person and online, use group exercises to generate real laughter without relying on jokes or humor. Many women find that the laughter starts out forced but quickly becomes genuine once the group gets going. Studies on this practice during pregnancy have consistently shown benefits for mood and symptom management.
Outside of structured practice, surrounding yourself with comedy you enjoy, whether that’s a podcast, a TV series, or a friend who always makes you laugh, is the simplest path. Even short bursts of laughter count. You don’t need a 30-minute laughing session to get the endorphin boost. A few moments of genuine, hard laughter are enough to shift your stress chemistry in a positive direction.
