A few words on drinking, dehydration and travel

As I have spent some time in airports and in airplanes recently I noticed how little people are drinking! Say what? What I mean is, I noticed how little WATER people are drinking. I see people drinking lots and lots of coffee, but also fruit juice, tea, wine and beer. These drinks all contain dehydrating agents which makes them act like a diuretic. The person sitting next to me on the flight only had one glass of water during a 10 hr flight.To me this is crazy, knowing a bit about anatomy and the importance of hydration!

Other then the 1 glass of water she had a couple of glasses of orange juice, 2-3 glasses of wine with the food, and then a couple of cups of coffee. Just before we got off the flight she took an ibuprofen/aspirin to “help her with the headaches”. She said she always get them on these long flights. I was not surprised having noticed her “drinking” habits, as getting a headache is one of the common signs of dehydration along with feeling really tired.

Did you know that because of the pressure changes when flying and all the extra noise, our taste buds are overwhelmed and we cannot taste the food very well. That means that airplane food always has way more salt and sugar in it than normal, in order for us to taste it. In terms of hydration this is not good, because the excess salt and sugar will act on the body as a dehydrating agent.

We have probably all heard that it is important to stay hydrated, but what does that really mean, and how does that differ from person to person? What part does salt play in staying hydrated? It turns out it plays a very important part. “ But I heard that salt is bad for you, what’s up with that?” I will delve deeper into these topics for next weeks blog.

If this is your color…

But just for a quick tip right now, when you go to the toilet – pay attention. Your pee should be a very very light yellow, every time that you go to the toilet. Then you know that you have enough water in your system. The stronger the color gets and odor, it’s a sign that you are getting more and more dehydrated. You should easily drink above 2 Liters of WATER a day. And add some good quality salt to your food or drink as well. I will explain the correlation between salt and water further in the next blog.

In the ideal world, the best thing for your hydration during your next trip would be to bring your own food and drink nothing but water. If that is too much out of your comfort zone at the moment, at least limit drinks that acts as diuretics as much as possible, such as fruit juice, coffee, tea and alcohol.  From Wikipedia “A diuretic is any substance that promotes diuresis, that is, the increased production of urine.” Jet lag is also always harder to get over when your body is dehydrated, because it makes you more tired.

Here are a couple of more questions challenging the “what you think you know comfort zone“. Did you know that:
-in prolonged dehydration, the brain cells begin to shrink?
high blood cholesterol has a direct link to dehydration?
morning sickness in pregnancy has a direct correlation to your body’s hydration?

So, keep sipping that water and I will catch up with you next week! 🙂
