When we are in fear, our body releases stress hormones and goes into “fight or flight” (sympathetic nervous system dominance). In a state of stress, the immune system’s ability to fight off antigens is reduced and we become more susceptible to infections (bacterial, viral, parasitic, etc.). The stress hormone corticosteroid can suppress the effectiveness of the immune system by lowering the number of lymphocytes.
The best way to get out of fear and to build immune system resilience is to shift our breathing to calm our nervous system. When we shift out of “fight or flight” (sympathetic nervous system dominance) we can get into a space of love and connection while supporting our nervous system.
