"I'm prone to sinus headaches, and I just purchased this Unimi Heated Eye Mask ($15) from Amazon over the holidays. Though you can put it in the freezer, I like to heat it up in the microwave for 30 seconds at a time. It's weighted, so that helps to relieve sinus pain, as does the soothing warmth against my face. The lavender smell is also a bonus! I'd say this is a great accessory to have during cold and flu season." — Sam Brodsky, assistant editor, Fitness
