Cold sore: Viruses or localised infections can cause the eye to redden â the problem usually starts in one eye, but can spread to both. The cold sore virus, which 90 per cent of us carry, can sometimes also infect the eye, causing inflammation.
Endorphins are chemicals, called peptides, that are made in the body. They have much of the same effect on a person as opium or morphine. As a result, they actually lower the feeling of pain in the body and can create a feeling of bliss or euphoria.
Endorphins have many positive effects on the body and mind. When endorphins are released it lowers the blood pressure; high blood pressure is a major indicator for heart disease. Endorphins boost the immune system, slow down the aging process, and reduce pain, and anxiety. Endorphins have been shown to reduce symptoms associated with eating disorders. Endorphins also regulate the production of sex hormones. Scientists have discovered that beta-endorphins can trigger human NK (Natural Killer) cells and support the immune system against diseases and kill cancer cells.
