Anyone who has traveled extensively knows just how tiring this process can be. In addition to dealing with new time zones, you might also find yourself struggling with uncomfortable airport seats and cold airplane cabins for hours at a time. Whether you are heading to see your family for the holidays or traveling to another country for business, here are four accessories you should have in your carry-on at all times.

Noise-Canceling Headphones

While cheap earbuds are perfectly fine for listening to music at the gym, they probably won’t be quite as useful while you are traveling. A good set of noise-canceling headphones will drown out the world around you so that you can sleep, relax, or focus on an important project. Unlike the cheaper alternatives, they are designed specifically to mute all outside noise even when they are not connected to a phone, tablet, or laptop.

A Universal Travel Adapter

An all-in-one travel adapter could save you an immense amount of time while you are out on the road. No one wants to spend hours walking around an airport trying to find an outlet that matches one of their chargers. Universal travel adapters will quickly turn any outlet into a viable source of power. As an added bonus, many of these devices even turn a single outlet into multiple outlets so you can charge all of your devices at the same time.

A Travel Pillow

One of the single best investments that a frequent traveler can make is a comfortable travel pillow. Some companies, like GoSleep, know that unlike pillows on your bed, these are designed to support your head and neck in unusual positions such as leaning against a wall at the airport or resting on your knees during a flight. If you plan on bringing a pillow with you, then you should also consider a comfortable sleep mask that will block out the light.

Comfortable Footwear

Even if you have an important meeting just minutes after you land, you probably don’t want to travel in uncomfortable shoes. Hybrid slippers are designed to keep your feet warm and comfortable without sacrificing your safety. They often have excellent padding and traction so that you can walk around without feeling like you are going to slip and hurt yourself.

Traveling is almost always going to be tiring, but that doesn’t mean it needs to be painful or stressful. Keeping these few items in your carry-on will allow you to stay content and comfortable no matter where you are going.
