Calming an overactive amygdala is like soothing an over-caffeinated squirrel. First, recognize that it's been sipping too much espresso (stress). Mindfulness practices can help—it's like switching the espresso for a soothing herbal tea. Deep breathing exercises can also tell your amygdala to chill out and stop overreacting to every little thing. It is also important to engage in daily lifestyle practices conducive to well-being, such as regular quality sleep, movement, and social engagement.
