Verified step by step guidance
1
Step 1: Understand that stress triggers a physiological response in the body, often called the 'fight or flight' response.
Step 2: Recognize that common physical signs of stress include changes in heart rate, blood pressure, and immune function.
Step 3: Identify that increased heart rate is a typical physical sign of stress because the body prepares to respond to a perceived threat.
Step 4: Note that improved concentration and enhanced immune response are generally not associated with stress; in fact, stress often impairs concentration and weakens the immune system.
Step 5: Also, decreased blood pressure is not a common sign of stress; stress usually causes an increase in blood pressure.
