Hydration, moisturizer, earplugs are indispensable items to avoid bacterial infection or fatigue after the flight.

1. Snacks
Sitting on the plane for hours can make your digestive system sluggish. Bring an apple or pear in your carry-on bag to timely supplement fiber for your body. Avoid consuming high-calorie foods, as your only need is to eat to alleviate boredom rather than to feel full.
2. Moisturizer
The temperature and air circulation at airports and tourist centers can vary greatly. This can lead to dry, dull skin. Don't forget your skincare routine at home; bring along a box of moisturizer to protect your skin from environmental damage.
3. Hydration
Dehydration not only drains your energy but also weakens your body's ability to eliminate toxins, compromising your immune system. Therefore, prepare a water bottle when boarding a plane and avoid consuming alcoholic or caffeinated beverages.
4. Nasal saline spray
Dry winter weather, coupled with the air in the airplane cabin, can dry out your nasal passages and make you more susceptible to infection. Hence, carry a small bottle of nasal saline spray to moisturize your nose and prevent bacterial infections.
5. Hand moisturizer
Similar to the nose, hands are prone to dryness and cracking, providing a gateway for bacteria to enter. Carry hand cream along with a pair of cotton gloves so you can enjoy a DIY spa treatment while sitting on the plane.
6. Earplugs
The noise on the plane can be discomforting and lead to temporary hearing issues. Therefore, bring earplugs or noise-canceling headphones so you can relax, rest, and protect your ears.
