A man’s brain actually shrinks when he becomes a dad? 🧠

Dr Darby Saxbe explains that fathers can lose grey matter after having a child, but it’s not necessarily a bad thing.

She compares it to the brain clearing out unnecessary debris, becoming more efficient at processing social information and responding to the needs of a child.

And the more hands-on the father is, the greater these changes can be.

Brief Summary

Fathers experience brain shrinkage that enhances empathy and social processing as they bond with their infants.
