The fight, flight, or freeze response refers to involuntary physiological changes that happen in the body and mind when a person feels threatened. It can cause rapid breathing, flushed skin, tense ...

The second stress response system, known as the HPA axis, involves the hypothalamus, pituitary gland, and adrenal glands working together to maintain stress activation through hormonal signaling.

On the flipside of fight-or-flight is rest-and-digest. It’s the body’s way of rebalancing itself after the danger has passed.

The fight-flight-freeze response is a type of stress response that helps you react to perceived threats, like an oncoming car or a growling dog. It’s a survival instinct that our ancient ...

While the stress response is necessary for survival, frequent activation due to daily stressors can take a toll on health.

Critical to this "fight-or-flight" or stress response is a molecular cycle that results in the activation of protein kinase A (PKA), a protein involved in everything from metabolism to memory ...
