Long-term stress triggers the release of cortisol, which suppresses white blood cell (WBC) production—your body’s natural defense army.
With fewer white blood cells, your body becomes more vulnerable to infections, viruses, and slower recovery times.
When stress hormones stay high, they can trigger inflammation throughout the body, which weakens your immune system’s ability to function properly.
Stress doesn’t just lower WBC numbers, it also makes existing cells less effective at fighting off threats.
Stress-related insomnia can reduce immune cell regeneration, weakening your immune defense even more.
Exercise, mindfulness, healthy sleep, and a balanced diet can help regulate stress hormones and support immune health.
