(Answer: True)
It's true! Stress can be thought of as a threat to homeostasis. Homeostasis refers to the state of stability and balance that your body strives to maintain. When you experience stress, it is often caused by a disruption to this balance, and your body responds by releasing hormones that trigger a cascade of physiological changes.
When you're stressed, your body is basically screaming "Something is wrong! I need to fix it!" And so it ramps up your heart rate, heightens your alertness, and directs more blood flow to your muscles - all in an effort to keep you safe and prepare you to react to the threat.
So in a way, stress is your body's way of saying, "There's an issue here that needs to be addressed. Stand back, everyone, I've got this."
