Anxiety, Insomnia Linked to Weaker Immune Defense

New research indicates a potential connection between anxiety, insomnia, and a compromised immune system in young women. The study, involving 60 female students, explored how symptoms of anxiety and sleeplessness might affect immune cell counts. Findings revealed that participants experiencing anxiety or insomnia had lower levels of circulating natural killer cells.

These natural killer cells play a vital role in the body's defense against threats like viruses and cancer cells. A reduced number of these cells could impair the immune system's effectiveness, potentially increasing susceptibility to illnesses, certain cancers, and mental health conditions such as depression.

The research, published in Frontiers in Immunology, highlights the significant physiological consequences of psychological distress. Understanding this link could pave the way for better prevention strategies against immune-related disorders and cancers, emphasizing the importance of mental well-being for physical health.
