There is no argument, however, that without rest the body has trouble handling stress. You will feel pain more when you are tired. For many, lying down to sleep at night is when their pain is at its worst. Things are quiet and the only thing to focus on is the pain itself. Relaxation exercises, soft background music and even a television on quietly may help a person drift off to sleep.
Sexual activity is another technique used to help with chronic pain.
It may have something to do with those endorphins we release that help with the pain. Some need to rely on sleeping pills in order to get their rest. These can be prescribed by a doctor or bought over the counter. Either way, make sure you are careful here. Some of these pills can become addictive.
