Sleeping on transport, whether a plane, train, or bus, is all about light, sound, and support. First, invest in a high-quality neck pillow (like the Trtl or a memory foam wrap) to keep your head from "bobbing," which often triggers waking. Second, use noise-canceling headphones or earplugs to block the ambient engine drone (which can be as loud as 85 decibels) and an eye mask to signal to your brain that it's time for melatonin production. Third, dress in breathable layers and keep a "blanket scarf" or jacket handy, as transport cabins often experience sudden temperature drops. If you are on a long-haul flight, try to secure a window seat so you have a solid surface to lean against and won't be disturbed by seatmates needing to move. Finally, avoid heavy meals or excessive caffeine before your journey, as they can make your rest fragmented and less restorative.
