Story at-a-glance

  • Adrenal fatigue isn’t recognized as a real medical condition, but the symptoms people report — chronic exhaustion, salt cravings, brain fog — are very real and deserve closer investigation
  • The adrenal glands don’t “burn out” from stress, but persistent overload disrupts your brain’s communication with them, leading to hormone imbalances and daily exhaustion
  • Studies show no evidence that fatigue is caused by adrenal impairment; however, chronic stress does impact your hypothalamic-pituitary-adrenal (HPA) axis, affecting energy, sleep, and mood
  • Caffeine doesn’t directly damage your adrenal glands, but overuse combined with stress and poor recovery can mimic the symptoms often blamed on adrenal fatigue
  • Low energy might not be from your adrenals at all — thyroid issues, iron deficiency, poor sleep, or emotional stress could be the real reasons you’re always tired
