Scientists have figured out what happens to the heart when a person falls in love

Oxytocin, which the brain produces and is sometimes called the “love hormone,” can literally heal “broken people.”

hearts."In a new study of zebrafish and human cells, scientists found that it helps regenerate heart tissue after injury. According to biologists, theoretically, their discovery will be useful for treating heart attacks in the future. However, since the new study was conducted in aquariums and laboratory dishes, this theory is still far from being realized.

Oxytocin is called the “love” or “cuddle” hormone.for its renowned role in creating social bonds and trusting relationships. It often increases when people cuddle, have sex, or have an orgasm.

However, oxytocin also performsmany other functions in the body. For example, it is responsible for uterine contractions during childbirth and subsequent stimulation of lactation. According to a review published in the 2020 journal Frontiers in Psychology, oxytocin also helps protect the cardiovascular system from injury by lowering blood pressure, reducing inflammation, and scattering free radicals, a reactive byproduct of normal cellular metabolism.

New research published in the journalFrontiers in Cell and Developmental Biology, highlights another potential benefit of oxytocin, at least in zebrafish. The hormone helps the heart replace damaged and dead cardiomyocytes, the muscle cells that are responsible for heart contractions. Early experiments on human cells showed that oxytocin could produce similar effects in humans if administered at the right time and in the right dose.
