When you experience stress, whether it's physical, emotional, or psychological, your body begins a complex process of changes known as the stress response. This response triggers the release of stress hormones like cortisol, which is a steroid.
While the stress response is a mechanism designed to help you cope and adapt to with short-term challenges, long-term (aka: chronic) stress can have a profound impact on your immune system. Here's how:
1. Suppression of immune cell function: Prolonged exposure to stress hormones can suppress the activity of immune cells, including natural killer cells, T-lymphocytes, and macrophages, which are crucial for fighting viral infections like HPV (6).
2. Reduced antibody production: Chronic stress has been shown to decrease the production of antibodies, which are essential for neutralising viruses and preventing their spread (2).
3. Increased inflammation: Stress can lead to a persistent low-grade inflammatory state in the body, which can negatively affect immune function and create an environment that favours viral persistence (4).
4. Impaired viral clearance: Studies have found that individuals experiencing chronic stress may have a reduced ability to clear viral infections, including HPV (3).
