A reader asks:

My 24-year-old daughter had a kidney transplant three years ago and will always be on anti-rejection meds. She cannot be in the sun or use tanning beds due to the increased risk of skin cancer. Is light therapy an option for her?


You don’t say what your daughter would be attempting to treat with light therapy. But a light therapy device which filtered out virtually all UV (ultraviolet light) – for example, the light therapy box CET recommends – would eliminate the risk of UV exposure. First, however, you should make sure that none of your daughter’s meds are affected by the visible blue range.
