Stress or fear can instantly alter immune reactions.
Inflammation affects brain chemistry and mood.
The vagus nerve helps regulate immune calm.
Cytokines can influence sleep, motivation, and fatigue.
Chronic stress keeps immune alarms switched on too long.
Meditation and breathing activate neural-immune balance.
Neuroimmunology studies this intricate cross-talk.
Your “gut feeling” literally involves immune-nerve interaction.
Mind and immunity are deeply intertwined partners.
