Frequent Sickness
If you find yourself frequently battling the sniffles, stress might be to cause. Stress can weaken your immune system and make you more susceptible to diseases. In one trial, 61 elderly people were given the flu vaccination. Chronic stressors had a diminished immunological response to the vaccination, showing that stress may be linked to lower immunity. In another research, 235 people were divided into two groups based on their stress levels: high or low. Over the course of six months, individuals in the high-stress group had 70% more respiratory infections and roughly 61% more days of symptoms than those in the low-stress group.
Similarly, one meta-analysis of 27 studies found that stress was associated with an increased risk of acquiring an upper respiratory infection. The more human study is needed to understand the complicated relationship between stress and immunity. When it comes to immunological function, however, stress is only one component of the jigsaw. A reduced immune system can also be caused by a poor diet, lack of physical exercise, and immunodeficiency illnesses such as leukemia and multiple myeloma.
