Probably many people here know this already, but
I was just on the facebook sarcoidosis forum and I saw a mention that memory foam mattresses can cause asthma and breathing problems. (The poster speculated that this caused sarc., too.) Looked into it, and rashes, night sweats and itchiness are also attributed to memory foam.
I'm yanking my memory foam pad off my bed tonight. I do remember that my sore back problem, which ended when I bought the pad, was right before my breathing problems started.
There may be a good thread on this already but it doesn't come up easily, so I thought I would mention it. If someone knows the thread, please point it out to me.
Edited, December 25 - I'm adding this from ehow to my original post.
A "Respiratory problems memory foam" google brought up this on ehow:
Another major issue with memory foam mattresses is represented by the respiratory problems it may cause. Chemicals used in memory foam can irritate the lungs and cause breathing issues for some people. Chemicals such as polyhydroxy polyol and toluene di-isocyanate petroleum products are harsh toxins that harm the lungs. Not everyone who sleeps on a memory foam mattress will develop these problems, but if your lungs are weak or you are susceptible, you may want to try a different type of mattress.
The Mom Logic Website also says, many people complain about having sore throats, itchy eyes and bloody noses after sleeping on a memory foam mattress.
