Get your rest, and look good doing it! Instead of wrapping your entire head in a hot, stuffy, used blanket simply wear a sleep mask and get the rest you need. Cheap sleep masks often let in light and press against your eyes uncomfortably. A 3D eye mask relieves the pressure on your eyes giving you a relaxing and deep sleep that you need to make those tough decisions while on the go.
You deserve to get your rest...why not look cool while you do it?
