For Thai readers, the sight of joyful crying—at weddings, graduations, or family reunions—is a familiar and moving part of life. Yet, few might pause to ask: why does the body respond to intense happiness with an act so closely associated with sadness? Neuroscience explains that crying, whether prompted by sorrow or jubilation, is a response to overwhelming emotion. Both happy and sad tears originate from the same neurological circuits, highlighting the brain’s struggle to process feelings that push us past our usual emotional limits.
