How stress shows up physically

Short bursts of stress are normal. Chronic stress keeps cortisol elevated, which over time can contribute to headaches, digestive issues, higher blood pressure, and difficulty sleeping.

Stress does not cause every illness, but it can make existing conditions harder to manage.

Signs your stress load is high

  • Trouble falling asleep despite feeling tired
  • Jaw clenching or tension headaches
  • Irritability over small frustrations
  • Skipping meals or overeating
  • Avoiding activities you used to enjoy

Small actions that compound

Pick one boundary this week: a firm end to work email, a 10-minute walk after lunch, or saying no to one optional commitment.

Many insurance plans cover a limited number of therapy sessions. Check your behavioral health copay and in-network counselor list before you are in crisis mode.
