How to Actually Sleep on a Road Trip Without Wrecking Your Body

The passenger seat challenge
Car seats recline, but not far enough. Headrests push your head forward instead of cradling it. Seatbelts dig into your shoulder and collarbone. Every lane change and bump snaps your neck awake. The passenger who arrives rested is not lucky; they planned for the physics of a moving vehicle.
Seat position for side-sleeping
Recline the seat to about 110 degrees, not flat. A fully flat seat puts pressure on your lower back and can cause nausea. Place a small pillow or folded jacket behind your lower back for lumbar support. Lean against the window side if possible; the door frame gives you something to rest against. A U-shaped travel pillow against the window prevents your head from bouncing.
Front seat versus back seat
The front seat has more legroom but less head support. The back seat lets you curl up in the fetal position if the middle is empty. If you are in the back, use the seatbelt across your lap only if local laws allow, and wedge a pillow between your knees to keep your hips aligned. The front passenger seat is best for upright napping with a neck pillow.
Timing your nap around the drive
The first two hours of a road trip are exciting; nobody sleeps then. The window for good rest is hour three through five, when monotony sets in. After hour five, adrenaline and restlessness return. Plan your longest nap for the middle third of the drive. Set an alarm for 45 minutes to avoid grogginess.
Car temperature and ventilation
A warm car makes you drowsy but does not produce quality sleep. A cold car keeps you alert but tense. Set the temperature to 68 degrees if possible. Point the vents away from your face. Stale air causes headaches, so crack a window slightly or run the fresh-air intake rather than recirculate. Sunglasses or an eye mask block the visual stimulation of passing scenery.
Bring the right neck support
A travel pillow designed for upright use is the difference between arriving refreshed and arriving with a crick.
