"I really like using the Gaiam Lower-Back Wrap ($16, originally $20). It's microwave-safe and smells like lavender, which is extra soothing. The day that I get my period every month is always less-than-fun because I suffer from shooting cramps in my pelvis, so I've also used this as a heating pad during that time. It's definitely brought relief to my unbearable period cramps and helps me take moments of rest before getting back to any tasks I have to do that day." — Sam Brodsky, assistant editor, Fitness
