What’s Going On: Your shoulders are tense, your heart is racing, you might even feel like you want to throw up. Feeling stressed or anxious is your body’s instinctual way to prepare to either fight or flee a perceived threat. This instinct was necessary back in caveman days, when your ability to react quickly meant the difference between staying alive and being an animal’s lunch, but that fight-or-flight response is less helpful when you’re confronting an upcoming test or just thinking about the state of the world.
The Upside: “Facing anxiety can make you into a stronger person,” says Beresin. And stress about a future event can actually help your performance. When you’re stressed, your body produces a hormone called cortisol, which helps with focus and makes you able to react quickly, so you can perform tasks (like taking a test) efficiently.
Put It to Work for You: Use that nervous energy to motivate yourself. First, separate things you can control from what you can’t. For example, if you’re stressed about that test, you can’t control what questions will be on it, but you can control whether or not you prepare for it. Next, come up with a concrete plan for addressing the parts of the situation you can control (like studying 30 minutes a day for the test).
