When we are stressed, the body releases stress hormones such as cortisol (Cortisol) · In the short term this hormone is beneficial, helping us cope with situations · But when stress becomes chronic, continuously elevated cortisol suppresses the function of the immune system, making the body less able to fight off pathogens · Managing stress is therefore part of caring for your health and immunity
1 How chronic stress affects immunity
| Effect | Details |

| Get sick easily, recover slowly | Colds, cold sores, or infections become more likely during stressful periods |
| Chronic inflammation | Stress is associated with low-grade inflammation in the body |
| Affects sleep and the gut | Stress → poor sleep + gut disturbance → loops back to affect immunity again |
