While movies often depict flying as a lavish and sexy mode of transport, it does come with its own caveats. Air travel takes a huge toll on the body; dry air, motion sickness, and jet lag make up just the tip of the iceberg when you are thousands of miles up in the sky for extended periods of time. Cabin air is a mixture of recycled and frigid exterior air, which is only capable of holding 10% of moisture in high altitudes as compared to the ground. That is why our nasal passages, eyes and buccal membranes often feel scratchy and painful when we are in prolonged contact with cabin air. Transepidermal water loss or TEWL is accelerated, causing our dermis to become dehydrated and the skin’s oil-water balance to be out of whack. This leads to uncomfortably tight skin that’s dull, flaky, sensitised and prone to breakouts. Then there's also an issue on the questionable water quality in planes. Potable water used in your coffees and teas are found to contain traces of bacteria, insect eggs, and contaminants according to a Business Insider report. To be safe than sorry, it is always good to bring or request for bottled water to avoid coming in contact with the unhygienic tap water on the aircraft. Luckily, there are products designed to keep us hydrated and sanitary even when the conditions are against us. Here are some that you should definitely pack in your carry on Dopp kit the next time you fly.
