Stress can affect the immune system, and in some cases, it may lead to changes in neutrophil levels. During periods of stress, the body releases stress hormones, such as cortisol, which can influence immune cell activity, including neutrophils. While short-term stress may not cause significant changes in neutrophil levels, chronic or severe stress can have a more profound impact on immune function, potentially leading to alterations in neutrophil counts. Additionally, stress can indirectly affect immune function by influencing behaviors, such as sleep patterns, diet, or exercise, that play a role in overall health. Maintaining a healthy lifestyle and implementing stress-reduction strategies, such as mindfulness techniques, regular exercise, and adequate sleep, can support overall immune health.

However, excessive or prolonged neutrophilia can sometimes contribute to tissue damage due to excessive inflammation.
