I'm a health editor and these are the travel essentials I won't leave home without

Packing cubes are easily one of the best travel accessories of my time — I have a set for every member of my family. These handy travel helpers are made of water-resistant nylon and range in size and purpose. This eight-piece set includes a large, medium and small packing cube with straps to securely hold everything in place, plus an undergarment bag, a toiletry bag, an accessories bag, a laundry bag and a shoe bag. 

I can easily keep everything organized by tops and bottoms or have a cube dedicated to casual clothes, one for workout clothes and a cube just for dressier outfits. And when staying in a hotel for an extended time, I unpack in minutes by slipping the cubes into the dresser drawers. These are worth every penny and then some!

Speaking of game-changers, the PackIt Freezable Lunch Bag is something I use year-round for lunches, picnics and travel. Whether traveling by plane, train or automobile, eating on the go can be downright dangerous when you're at the mercy of random food stops and airline meals. The PackIt cooler keeps medication, snacks, sandwiches, fruit and veggies cold and fresh for over 24 hours. I also love that when I am finished using the bag, it folds up nicely to fit in compact hotel refrigerator-freezers, so it's cold and ready for a beach picnic or our return trip. 

I've had the PackIt lunch bag I'm currently using for about seven years, and it's held up beautifully! My newest Packit bag is a freezable grocery tote which is wonderful for summer markets and family picnics!

Since our early 30s, my husband and I have sworn by the use of compression socks when flying long distances, and even A-list celebrities like Jessica Alba sing the sock's praises, too. Staying seated for long periods, especially when traveling by air, can cause swelling, leg cramping and pain that is exacerbated by dehydration, and even deep vein thrombosis. Studies have repeatedly found that compression socks reduce flight-induced ankle edema, travel symptoms of leg pain, discomfort and swelling, and improve energy levels, the ability to concentrate, alertness and post-flight sleep. 

Os1st is a brand I love and trust for many of my therapeutic sock needs. The socks are well made, the customer service is outstanding, and the company is always working to improve its socks and create new, cutting-edge designs. These compression socks look like dress socks and feel extremely comfortable when worn for extended periods.

If you don't love those crescent-shaped travel neck pillows you see people with around the airport — I personally find the pillows cumbersome to carry and not very comfortable to use — then this inflatable pillow is well worth a try. I came across this inflatable pillow while looking for something for my son to take camping. When it arrived, I was blown away by how soft and lightweight was — and how compact it was when not in use. After realizing I could inflate the pillow to my desired firmness or only partially and fold it in half to use as a lumbar cushion, I immediately ordered two more for my husband and I to use while traveling. At under $30, this pillow with a removable, machine-washable cover is a steal, and makes a fantastic gift for the traveler or camper in your life.

Did you know that the microclimate of an airline cabin consists of dry, recirculated, cool air, which studies have found can quickly cause dehydration, especially on long-haul flights? In fact, to maintain proper hydration, it's recommended that you increase your water intake by 15–20 mL for each hour of flight.

Taking a refillable water bottle with you on trips will not only help you stay hydrated but also help protect the environment. I am a huge fan of Hydro Flask, which keeps my water ice cold for over 24 hours. (Just be sure that it's empty before you go through TSA checkpoints.)

Being dehydrated by just 2% impairs performance in tasks that require attention and immediate memory skills. When traveling, especially by air, staying hydrated can be a difficult task. To help me stay hydrated on-the-go, I love these electrolyte powder packs from DripDrop. All I have to do is add one pack to 8 oz of water, give it a good shake, and in seconds, I have an electrolyte-fortified drink to help me stay hydrated. 

If you prefer tablets over packets of powder, try the Nuun Hydration Immunity Electrolyte Tablets with Vitamin C.

If you take multiple medications, vitamins or supplements, one of these large pill organizers will be a welcomed addition to your travels. I particularly like this one from Daviky since you can use it to organize one, two or four weeks' worth of medication. 

As a rule, I never travel without a first aid kit. Sometimes I'll make the kit using a ziplock bag and first aid items around the house, other times, I'll nab one of these 80-piece first aid kits. The size that I take depends on the destination and the number of days I'll be traveling, but I always bring one — because cuts, scrapes, bruises and headaches are inevitable with my family when on the go.

Being that our annual trip around the world lands us in Australia, there is no way I am leaving home without our SharkBanz magnetic shark repellent bracelets. Sharkbanz patented technology has been extensively tested by the Western Australian Government, and does not require any charging or batteries, so it is always on and working. The bracelet works by overwhelming the sharks’ electroreceptors, which causes it to turn away. If you are heading to the ocean, I cannot recommend these lifesaving "banz" enough. The peace of mind these magical lifesavers bring me when my family is in the water is priceless. You can wear it on your wrist or ankle, and it's fully adjustable to fit young and old!

Traveling can be hard on your immune system, especially if you are rundown from always being on the go. These Emergen-C immune support gummies are a great complement to your daily multivitamin. Each gummy is packed with immune-boosting Betavia (R), 1,000 Mg vitamin C, vitamins B and D and antioxidants.

Over the years, I've left more full bottles of expensive body wash, shampoo and conditioner in hotel bathrooms than I care to admit. Well, not anymore! These handy travel bottle sets have officially put an end to that. From shampoo and conditioner to body wash, lotions, potions and styling products, these hold it all and just the right amount. 

This kit includes a slew of TSA-approved pieces: four leak-proof silicone squeezable bottles, four travel jars, two spray bottles, two spoons, a funnel, a cleaning brush, labels and a transparent makeup bag. I also like that each container is labeled with the number of ounces it holds.

These days, I barely leave home without a backup phone charger, let alone travel without one. This charger from Ixnine has 26800mAh, which for me, can charge my phone about three to four times before I need to charge the power bank itself. With three USB ports and one USB-C port. It can charge up to four devices at once, but I have yet to try that and cannot attest to the speed or how long the bank will last. I also really like the LED indicator that shows the percentage of remaining charging power.

Travel slippers are must for me when it comes to air travel and hotel floors. These Snoozies slippers are great for being both compact and comfy. The inner liner is a thin sherpa-like material, and the bottoms are soft with an anti-skid covering. While you wouldn't want to wear the slippers outside, the thin material makes it so you can repeatedly wash-and-wear (including the carrying bag) without damaging the bottoms. The slippers are also great for airport security, hospital floors and friends and family members who ask you to leave your shoes at the front door. See all 14 colors and patterns.
