Stress clearance, focus, mood, and the genes behind them.
Your brain's ability to handle sudden stress depends on how quickly it clears dopamine from your prefrontal cortex. Variations in the COMT gene dictate whether dopamine lingers to create mental overload or breaks down steadily to sharpen focus, shaping how you perform under tight deadlines.
Your body clears stress hormones at a genetically set speed, and the COMT and FKBP5 genes mean some people recover in hours while others take days.
