Many people with eczema have noticed that their skin rash gets better with mild to moderate amounts of sunlight exposure. It isn't exactly clear why this happens, but it may be related to the amount of vitamin D that the skin makes when exposed to sunlight. People with eczema are more sensitive to the sun, however, and need to be careful to not get too much sun exposure.

Carter's Inc, a popular company for baby clothes, makes a line of clothing with tag-less labels that have been causing rashes on the upper backs of about 400 babies. This has prompted the Consumer Product Safety Commission to issue a warning to this particular line of clothing, which is from the fall 2007 line. The reason for the rashes is not clear -- I suspect that the babies are experiencing contact dermatitis from the ink contained within the iron-on labels. Other forms of contact dermatitis from clothing can be caused by formaldehyde contained in clothing that has been worn before it was washed.
