My spouse found out recently that he probably has NHL. Doctor is still collecting various test results. He has bad night sweat. I am wondering if I get something like a DualTemp layer from SleepNumber, whether that will help him feel better sleeping. The product claims to be able to lower the temperature by 15 degree on the bed. It is pretty pricey. However, it would be worth the investment if something like that will help him feel more comfortable sleeping at night. Thanks for your input.
