6. Covering Your Eyes
Light is another reason why you may not be able to fall sleep on board. The first thing you should do is to block it. A sleep mask can resolve the issue. If there is no mask, use your baseball cap instead. The cap can be used as a shield from other people around to provide privacy. The cap can perfectly prevent other passengers from looking at your sleeping face. Another tip you can use is to apply a drop or two of essential oil onto the inside of the cap. It will block the smells and odors that come from foods, drinks and other people on the plane.
