Beyond coffee and singing at the top of your lungs, the easiest way to stay awake in the car is to avoid being too warm. Staying toasty might be comfortable, but it’s also seriously soothing to your body and helps induce sleep. Blast the air conditioning in the summer -- to the point at which you’re very cold -- or crack the windows in the winter. Your body is too chilly to doze off. Remember, if you get exhausted, always pull over and take a nap -- safety first!
