Research indicates that chronic inflammation, often driven by prolonged psychological stress, can persist for years and damage healthy cells. This condition is linked to more than half of all global deaths and can create a cycle where systemic inflammation exacerbates nervous system symptoms like fatigue.

Further studies from the Tehran University of Medical Sciences suggest that chronic stress influences cancer biology by affecting tumor growth, metastasis, and recurrence. This is driven by hormonal changes from the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis. Additionally, excessive stress is identified as a significant risk factor for cardiovascular issues, including heart attacks, strokes, and increased blood pressure.
