I recently joined a new online community on Fibromyalgia. I like to join communities for many reasons, there's great support and sometimes you can find out something new-- be that a new healing method or a new perspective on the disease. This particular site is not geared especially towards disease, on the contrary, it's geared towards bloggers. None the less, a new buddy recommended a site for me to look at. This site contains free mp3 downloads of music and sounds that are intended to help with brainwave entertainment. The particular site she referred me to is one strictly meant for mental health. Fibromyalgia is considered one of the mental health issues they have downloads for. Brainwave Entrainment put simply is using stimuli such as sound, light, or EM fields to influence the rate of our brainwaves, which in the process affects our mental state. This therapy is becoming quite popular over the internet and there are many, many sites that offer free downloads.
