Low Airline Cabin Humidity, Dehydration Can Make Jet Lag Worse Warns Water Advocate
A few Precautions Can Greatly Lessen Jet Lag Symptoms and Travel Fatigue Reports Sharon Kleyne Hour Power of Water Host

A recent London Daily Mail article suggested that "sucking on lemons" can reduce the symptoms of jet lag during airline travel because, "lemons have properties that will help fight off dehydration." To water advocate, researcher and radio host Sharon Kleyne, who has been studying dehydration for 30 years, the London Daily Mail article was significant because most articles about jet lag fail to connect its symptoms with the dehydration and travel fatigue caused by low airline cabin humidity.

Sharon Kleyne hosts the syndicated Sharon Kleyne Hour Power of Water radio show, heard on VoiceAmerica and Apple iTunes. The show is sponsored by Bio-Logic Aqua Research, a global research and technology center specializing in and fresh water, the atmosphere and dehydration. Nature's Tears® EyeMist® is the Center's signature product for dry eyes. Kleyne is Bio-Logic Aqua's Founder and Research Director. .
Kleyne will discuss jet lag, dehydration and the airline cabin atmosphere on her upcoming radio show of September 15, 2014

Jet lag symptoms, according to Kleyne, are attributed to a disruption of circadian rhythms caused by crossing three or more time zones within a relatively short period. When the body clock is off by three hours or more, the result can be disrupted sleep, fatigue, headache, indigestion and other symptoms. This varies greatly among indiv8duals.
It is important to note, says Kleyne, that some jet lag symptoms are similar to the symptoms of dehydration, which is also very common on airline flights. The reason dehydration symptoms are common is that the relative humidity in an airline cabin is normally maintained at around 10 to 20 percent, about that of Death Valley in summer. The airlines have good reasons for this. First, in a crowded cabin with recirculated air, bacteria can spread fairy easily. Ambient and surface bacteria are less likely to survive when the cabin atmosphere is dry and the humidity is low. Also, humidifying the air is expensive.

The problem with low cabin humidity, according to Kleyne, is that it can cause the body to lose water content, a condition called "dehydration." Symptoms of dehydration include headache, fatigue, stress, disrupted sleep, dry eyes and dry mouth.
Because many dehydration symptoms are similar to jet lag symptoms, Kleyne believes that jet lag symptoms are often made much worse as a result of dehydration caused by low cabin humidity.
Kleyne offers a simple solution: Drink water. Kleyne recommends a minimum of eight glasses per day, in addition to all other fluid intake. Water absorbs most completely, say Kleyne, at room temperature or warmer. Drink some of the water all at once rather than sipping and drink extra water before, during and after the flight. Avoid caffeine and alcohol, which are dehydrating. The airline will be happy to provide bottled water if you don't bring you own.
Kleyne also recommends a pure water mist to help keep skin and dyes hydrated. Her company's products, Nature's Mist® for skin and Nature's Tears® EyeMist® for eyes, are specifically intended to add instant moisture to exposed body surfaces on airline flights and other situation that pose a high risk for dehydration.
Kleyne had discovered that the transfer of water vapor from the body to the air under extremely dry atmospheric conditions, occurs primarily on the skin and eye surface and in the lungs. Keep the skin, eyes and lungs moist and the transfer will either be slowed or will not occur.
Kleyne is a strong advocate of sucking on lemons, but would serve the lemon slice with a glass of water.
