For some, drinking on a flight is a matter of course – but it does not always end well. After the plane has landed and your buzz subsides, you may feel like crap, possibly even worse, than if you had drunk on the ground.
In fact, Chrissy Teigen recently tweeted that she did not drink on a flight and came home "I feel like a normal, healthy being. It is very funny. I like it. Why do you feel so much worse when drinking on the plane?
We know that getting off the plane can cause dehydration ̵
1; and alcohol can make it worse.
Alcohol causes you to dehydrate With Dry Mouth May Leave Fatigue and a General Sensation of Crookedness According to the Mayo Clinic It also acts as a diuretic, meaning that you need to pee more, says Sanjay Kurani, Sanitary Director for Inpatient Medicine at the Santa Clara Valley Medical Center Assistant Professor of Medicine at Stanford University, opposite SELF.
And airplanes are not exactly the most moisturizing environment. "According to the World Health Organization the humidity in an airplane is lower than in most homes, which means The air is literally drier, so it's not uncommon for your skin to become drier Feels as usual – even before you start drinking  Dr. Joshua Zeichner a New York City-based dermatologist and head of dermatology cosmetic and clinical research at Mount Sinai Medical Center, tells SELF.
This can really affect the moisturizing parts of your body, such as the eyes, nose, and mouth, leaving you with dry mouths, dried-up eyeballs, and parched sinuses, Omid Mehdizadeh, MD, an Otolaryngology specialist at the Providence Saint John Health Center & # 39; s in Santa Monica, California, opposite SELF. Combine all this with the fact that you probably will not drink as much water as usual to prevent constant flights during the flight to the bathroom, and the effects of dehydration are very real, Dr. Kurani.
But that's not it You just have to worry about dehydration.
The air pressure in the cabins of commercial aircraft is relatively low, which can easily reduce the amount of oxygen that enters your blood and enters your brain. Carol Thelen, a practicing family physician at Mercy Medical Center in Baltimore, tells SELF what can make some people feel a bit dizzy.
So, if you drink, you can feel the effects of alcohol a little more intensely than usual, Dr. Kurani. "A drink in an airplane can be more than a drink on the ground," he says.
You probably will not sleep well either when you fly, thanks to the noise, uncomfortable sitting and the fact that you & # 39; They try to catch some ZZZs next to a bunch of strangers. Even if you really stand on your feet, alcohol can get confused with your ability to get REM sleep (the most restful form of sleep), and you feel dizzy and unfocused when you wake up, says the National Sleep Foundation  In addition, flying itself is exhausting. Basically, the crazy crazy feeling you get after drinking on the plane is not in your head – it's real.
You do not necessarily drink when you want something, but experts say there are ways to be smart about it.
In the beginning you know that you do not have to drink so much in the air to get the effect you would have on the floor. But that does not mean that you have to do without it altogether. "Many people enjoy enjoying a drink on the plane, and that's fine," says Dr. Mehdizadeh. "But if you want to drink, you'll find that you also need to drink water to replenish the water in your body." Although the exact amount you need can vary from person to person, it recommends one for each alcoholic Drinking cup of water you have to drink.
It's also a good idea to treat eyes and nose with eye drops and nasal salt sprays. Mehdizadeh.
But if you feel like you're getting shitty on a regular basis After a drink or two from the plane, it's worth trying a flight without alcohol and see where you're going. Like Chrissy Teigen, you may be surprised how good you feel.
