Let me add some more here, to help you understand why this is here. Dr Roerich and I where talking the other day, and he raised a topic about options he gives his patients in regard to treating depression, being light therapy, therapy and medication. I raised the point that another more proficient method exists, being exercise, hence this information is here as he went looking for substantial facts to divulge it, as we have discussed exercise and its benefits here plenty of times, yet never really posted anything of a scientific nature to back it up. I don't often do that, because I wouldn't put myself behind anything that I didn't know and have already read and experienced the factual aspects for myself. So this was probably needed for those who do want to see all the facts.

The pro's and con's to what Dr Roerich provided his patients, which I dare say now he may introduce exercise too them, are:

• Light therapy - an effective method in which to help treat depression whilst sitting at your computer. Only requires two short bursts per day.
• Therapy - effective only if the therapist is tough enough to push a person, then the person must be willing to actually do the work. Not so effective.
• Medication - well... the side effects say it all, plus putting unnatural substances into your body, and doesn't often treat the full range of depression and comes with suicidal ideation a lot of the time.
• Exercise - makes the body healthy, the mind healthy, increases the bodies natural mechanisms to pump blood where it need be, raises required chemical levels within the brain, and lots more. Only problem, exercise means a lifestyle change, and people are their own worst enemy. This is the most effective means to treating depression, but relies on the person wanting to help themselves, force themselves into a weekly exercise routine; rain, hail or shine, exercise must be done.
