UK surgeon explains how mother’s laughter during pregnancy can help the baby: ‘Your giggles are prenatal upgrade’

A happy mother means a healthy child- the idea has long been prevalent in society. Recent studies have shown that it has a strong basis in reality and that a pregnant mother’s laughter can help the baby in the womb develop vital traits.

Taking to Instagram on January 25, Dr Karan Rajan, a UK-based surgeon and health content creator, shared that while the baby is in the womb, a mother’s “giggles are basically a prenatal upgrade.” He went on to explain how it happens.

Calibrating the baby’s stress response

In fact, the rhythmic vibrations from the mother’s diaphragm while she is laughing create a gentle trampoline effect in the amniotic fluid, which serves as a “software upgrade” in the developing human.

“These low-frequency oscillations between 100 and 300 hertz actually stimulate your baby’s vestibular system,” noted Dr Rajan. “This controls their balance and coordination. It’s like a built-in prenatal rocking that enhances motor coordination before birth.”

“Studies suggest babies whose mums laughed more frequently during pregnancy showed superior head control at birth compared to those who didn’t,” he added.
