Stress is the body responding to an event or change, and it can cause "physical, emotional, or psychological strain." Due to the impact stress can have on you physically and mentally, it's important that you learn how to recognize when you're experiencing high stress.
Routine body scans can help you identify stress before you even realize that's what you're experiencing. If you sit and scan how each part of your body feels, you might notice differences when you're stressed, like jaw clenching or tension in your shoulders.
Remember that no one is superhuman and we all experience stress as a normal part of the human experience. The best solution is to create daily stress-relieving habits.
