Of course, however much you love your body pillow, all that wine and chocolate eventually takes its toll. Even if you manage to avoid chocolate stains, eventually the sweat of regular use will start to build up.

Along with sweat, dust and dead skin also collect on your pillow, which could cause allergic reactions, asthma, and other health problems.
