A study done at the University of California in Berkeley with a sample size of 61 healthy women showed a link between attachment ability and your immune system. The researchers found that "those who had difficulty establishing close, trusting relationships showed signs of weaker immune function. Specifically, lab experiments showed that the women's "natural killer" immune system cells were less lethal compared with those from other study participants."
It doesn't mean that being in an insecure relationship will kill you---but it does negatively affect your health. See insecurity leads to you being stressed. And chronic stress affects your immunity because it compromises your body's ability to fight infection. Your body's natural killer cells don't pep up when they are attacked because they are depressed.
The researchers also found a direct link between certain health problems and women who had attachment issues. These include plaque psoriasis, a condition where scaly patches form on the skin, and alopecia areata, an autoimmune disorder that causes hair loss. Ugh!
So in a nutshell, in order to further improve your health, stay out of relationships that have you feeling insecure. The right relationship for you should yield more endorphins and good energy than stress, negative emotions and sadness. Keep your head up.
Do you see any correlation between the two? Have you noticed a decline in your health in the past when you were in a stressed out relationship like migraines, colds and the like?
