Today's Sunday Mail carries a report in the health section about the above lamp. This review specifically states that use of this lamp, which is not cheap, 'can reduce the symptoms of Parkinsons'. It also says that a study conducted in Germany found that 'light therapy significantly improved tremors and mood in those with Parkinsons'.
I was wondering whether anyone had used this lamp and what their findings were. I think this sounds too good to be true and would need more recommendations before buying one. But, on the other hand, as tremor is my main symptom, I could be tempted.
