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 are considered to be natural opiates and for this reason they have a very important role in both labour and childbirth. As your pregnancy progresses your endorphin levels will increase to help you deal with the growing discomfort caused by some of your pregnancy symptoms. Endorphins have also been found to play an important role in bonding with your baby immediately after birth.
