Even the most frequent travelers struggle with jet lag. Enter: this tiny, highly portable device, which uses patented, NASA-backed science to emit a very specific wavelength of red light therapy (630nm, to be exact) which many travelers allege helps assuage jet lag. The 28-minute protocol is easy to use, and purports to help you regulate circadian rhythms and fall asleep faster. (Personally, I’ve been using this one for months, and I love it.)
