Humid Air May Be More Dehydrating than Dry Air Reports Water and Health Researcher

One would think that being in hot, dry air would cause the human body to lose more water than being in hot, humid air. And it is true that hot dry air does tend to draw more water out of moist objects than does hot humid air. According to water and health researcher Sharon Kleyne, other factors must also be considered. Kleyne has concluded that in fact, the presence of hot, humid air is more likely, not less likely, to cause physical dehydration and heat stroke in humans.

Humid Air May Be More Dehydrating than Dry Air Reports Water and Health Researcher

Sharon Kleyne is Founder of Bio-Logic Aqua Research, a water and health research and product development center that developed and markets the 100% water personal humidifying products Natures Tears® EyeMist® and Nature’s Mist® skin moisture. Kleyne hosts the globally syndicated Sharon Kleyne Hour Power of Water radio show on VoiceAmerica and Apple iTunes.

Kleyne points out that from the moment of birth, the body begins a lifelong dehydration process. The challenge to every living organism is to do everything possible to slow that process. In Earth’s increasingly polluted, overcrowded environment, with greater climatic extremes, human survival may depend on the ability to recognize and counteract early dehydration symptoms.

According to Kleyne, one of the most dehydrating bodily functions is perspiration. Perspiration is the body’s primary means of cooling itself and also plays a role in detoxification. Perspiration is 98% water and the rest is salt, oil, minerals and urea, a waste product from the blood.

The perspiration reflex, Kleyne explains, is triggered by three factors, an increase in the body’s core temperature as a result of fever or overwork, stress, and high surrounding temperatures. The water in the perspiration evaporates on the skin, causing the skin to cool as heat energy moves from the skin surface to the water to the air. The cooled skin then cools the venous capillaries, which eventually cools the body core.

Evaporation is always faster in dry air and in a hot but very humid situation, the water in the perspiration will evaporate much more slowly, if at all. When the humidity is too high, according to Kleyne, the body may be unable to cool itself in hot weather because no evaporation takes place. Under these circumstances, the body will continue to generate perspiration until there is simply no water left and the body is almost completely dehydrated. At that point, heat stroke sets in, which can be life threatening.

Kleyne explains that the solutions to dehydration from excessive perspiration are, (1) to remove oneself, if possible, from the situation causing the sweating and (2) to replace the lost water – and lost salt – as quickly as possible. Since the water in perspiration comes from the blood and not the skin, replacing the water by drinking is essential. Kleyne recommend drinking at least 8 to 10 glasses of water per day, in addition to all other fluids, and more when you perspire. The glasses should be pure fresh water with no additives. Kleyne notes that warm water is absorbed more quickly than cold water but does not cool quite as rapidly.

One of the earliest noticeable dehydration complaints, Kleyne points out, is dry, irritated, burning or itching eyes. While the water in perspiration comes from the blood, hot dry air also dehydrate the skin and eyes. Salt residue from dried perspiration is further dehydrating to skin and eyes.

To avoid eye and skin dehydration and discomfort in hot weather, Sharon Kleyne recommends her company’s products Nature’s Tears EyeMist® and Nature’s Mist® skin moisture. Both are completely safe, all-natural, and contain 100% trade secret tissue culture grade fresh water. The products are chemical free, non-allergenic and may be applied as often as necessary to keep skin and eyes moist and hydrated with Just a Mist no matter what the weather. .

New Education about Menopause, Dry Eye and the Global Dry Eye Crisis

Sharon Kleyne, host of the Sharon Kleyne Hour Power of Water syndicated radio talk show, recently interviewed Laurie Barber, MD, Professor of Ophthalmology at the University of Arkansas and a leading authority on dry eye syndrome. The interview may be heard on-demand on World Talk Radio, Voice America, Green Talk Network and Apple iTunes.

An important Sharon Kleyne Hour Power of Water objective is to raise awareness of the growing worldwide crisis in dry eye disease, and proactive steps that may be taken to prevent or alleviate dry eye symptoms. Untreated dry eye disease, according to Sharon Kleyne, can lead to corneal ulceration, visual impairment and blindness.

Sharon Kleyne is especially interested in the link between dry eye disease, air quality, polluted humidity, dry air, climate change, dehydrating indoor and outdoor environments and the amount of water we drink daily.

Noting that dry eye symptoms are the number one complaint that ophthalmologists hear from patients, Sharon Kleyne asked how Dr. Barber became interested in dry eye. Dr. Barber indicated that she practices in all areas of ophthalmology but does research on corneal inflammation, which can be caused by dry eye. There is no skin over the cornea and it is protected only by the corneal membrane and the tear film so it’s very delicate. If the tear film is healthy, the eye is likely to be healthy. And there are many important substances in the tear film aside from salt water – hormones, antibodies, mucins, lipids and so forth.

Sharon Kleyne noted that numeorus environmental drying factors that work against the tear film and can cause dry eye, dry skin and dry mouth. Also, dry eye ius often usymptomatic. Sharon asked abou the main symptoms of dry eye?

In younger people, according to Dr. Barber, there are very few symptoms. As we get older, after age 35 or so, we may lose the ability to keep the tear film in top-notch condition without helping it along, more among women than men. Dry eye after age 35, Dr. Barber explained, is believed to be caused by a drop-off in androgen, a male sex hormone, that occurs in both men and women. Dry eye symptoms include burning, itching, irritated, red eyes, and blurred vision. Also, what we call “eye fatigue.”

Sharon Kleyne cited a prior guest, Marguerite McDonald, MD, who observed that if you ever want LASIK surgery later in life, you should take excellent care of your eyes and contact lenses when you are young.

Sharon Kleyne then asked spedcifically about dry eye and menopausal women. I’m sure dry eye also shows up in men of the same age. Dr. Barber replied that older men are also prone to dry eye symptoms, esepciaaly men on prostate medication. The hormonal changes leading to menopause, she explained, start at around age 35 and men have some of the same hormone fluctuations as women. But women have a lot more hormones and a lot more dry eye.

S: Do you have any advice about artificial tears?

L: You need to limit it to four or five application a day, especially when using eye drops that contain preservatives, which can be an allergen.

S: You sound very concerned about vision care education. People are often unaware of the harm they can do to their eyes. Can you become addicted to eye drops?

L: That’s often talked about but I don’t think there have been any actual studies to determine whether using eye drops sets up a self-perpetuating need, as is the case with nose drops. Most people only use eye drops for a short duration.

S: Is there a test for dry eye?

L: The Shirmer test can be done by ophthalmologists or optometrists. They put a strip of blotting paper inside the eyelid for a specified amount of time and see how much liquid it soaks up.

S: What role does the skin around the eyes play in dry eye? Usually, when the eye is dry, the eyelids are inflamed and the eyelid skin is dry and flaky.

L: The lid margins are particularly problematic because that’s where the oil producing meibomium gland are located. The lids are also a “hot spot” for skin cancer. But any time you have serious symptoms, it’s time to see the doctor. They can recommend a pure water mist supplement like Nature’s Tears EyeMist, artificial tears, various medications, punctual plugs, etc.

S: And of course it’s important to keep eyes moist by drinking plenty of water – and I don’t mean coffee or soda.

L: Hydration and diet are critical. You should also eat green, leafy veggies, fruit and omega-3’s.

S: What about occupational health and eye care? Employers need to be taught about vision and forced air heating and cooling, computers, etc.

L: We all take our vision for granted until something bad happens. It’s human nature.

S: Could you talk about sleep and rest?

L: It’s very important to eye health, of course. It’s important to truly rest your eyes at night, and allow them to recover, which means not wearing contact lenses to bed. The tear film restores itself while you sleep – the glands recharge, the pH drops, etc.

S: Do you get a lot of patients with eye-stressing occupations or lifestyles, such as truck drivers or motorcycle riders?

L: Yes, those occupations all involve intense concentration or staring and the person often forgets to blink, which causes too much moisture to evaporate from the tear film. The best way to deal with that is prevention such as goggles or helmets, or pre-treatment such as applying eye drops or eye mist before you go motorcycling.

S: What about computers?

L: Computers also involve staring and cause you to blink less. You need to take frequent breaks to rest your eyes, make sure there isn’t a vent blowing on you, and position yourself to look slightly down on the screen.

S: And finally, tell us what to do about menopausal dry eye?

L: The same as you would for hot flashes. Exercise, drink lots of water, try to stay in a cool place and wear layered clothing so you can cool yourself off.

S: Exercise reduces stress and stimulates your system but can also be dehydrating.

L: Yes. So maybe as you get into menopause, you want to do only moderate exercise. If you’re training for a marathon – and I’ve worked with Olympic athletes – you need to be very meticulous about hydration. If you’re a swimmer, you need to watch your chlorine exposure.

S: Thank you so much, Dr. Barber. My next guest is Rebekah Jones of Lake Mead National Recreation Area in Nevada, who is going to tell us more about Lake Mead and especially about an invasive mussel shell that’s been causing no end of problems there.

Sharon Kleyne Reveals The Truth about Dry Eye, Water and the Cornea

Corneal dry eye could begin with water loss from the eye’s tear film.

“Ocular dryness (dry eye) can deplete corneal stem cells.”

Ula Jurkunas, MD, Harvard Medical School, July 11, 2011

Sharon Kleyne, water and health advocate, Bio-Logic Aqua Research Founder, and host of the Sharon Kleyne Hour – Power of Water radio talk show. New educational dry eye discovery will motivate the public to become more proactive in taking better care of their eyes – and the importance of the function of water in the tear film. The importance of water in alleviating dry eye symptoms and maintaining corneal health was discussed during two on-air interviews by Sharon Kleyne, with Harvard Corneal Researcher Dr. Ula Jurkunas, a clinician scientist heading corneal research (July 11, 2011) and with Lasik pioneer Dr. Marguerite McDonald, a clinical Professor of Ophthalmology at NYU and refractive eye surgeon (June 1, 2009).

Nearly everyone experiences dry eye and eye dehydration symptoms, including infants. Dry eye caused by dry air and diet accounts for 80% of eye doctor visits in the United States. Dry eye can lead to blindness. Most people in the world do not take the condition of dry eye seriously.

Recent research at Harvard University and elsewhere, now provides a graphic picture of just what happens, physically, when the eye surface, especially the protective “tear film” covering the cornea (the clear part of the eye), begins to lose water, resulting in dry eye and dehydration symptoms.

Doctors Jurkunas and McDonald agreed with Mrs. Kleyne that loss of water in the tear film is the underlying cause of dry eye. According to Dr. Jurkunas, “It is important to keep the cornea clear and hydrated. When the tear film is too dry, the cornea becomes somewhat irritated and opaque.” According to Dr. McDonald, “When the tear film lacks sufficient water, small corneal ulcers can begin.” Chronic dry eye could cause loss of vision.

According to Dr. Jurkunas, “Corneal stem cells originate in the conjunctiva (the fleshy inner corner of the eye) and migrate across the white (sclera) to the corneal epithelium (the membrane covering the cornea).” Ocular dryness can cause stem cell deficiency.

Dr. Jurkunas explains that chronic dry eye, eye infections, allergies, and other conditions, can lead to a permanent impairment in the production of corneal stem cells. This is called “corneal stem cell disorder.”

Dr. McDonald reported that dry eye disease is a health crisis in the United States that can lead to severe eye discomfort, loss of work productivity, stress, fatigue, allergies, impaired vision, and, ultimately, blindness. Sharon Kleyne revealed research has discovered that dry eye and tear film dehydration can be caused by numerous environmental conditions, including dry air (low humidity), polluted air, improper diet, sugar, lack of sleep, climate change, wind, insulated walls and windows, forced air heating and cooling – and most importantly, not drinking enough pure, 100% water.

Both Dr. McDonald and Dr. Jurkunas agreed with Sharon Kleyne’s concerns about the global dry eye crisis and her assertion that “good hydration equals good vision.”

Sight Preservation in Children around the World

Guest: Eugene Helveston, M.D., (Bloomington, IN), Professor Emeritus of Ophthalmology at Indiana University and a staff member of ORBIS International

This is a paraphrased summary of an interview on the Sharon Kleyne Hour – Power of Water Internet radio talk show on World Talk Radio, Apple iTunes and Green Talk Network. Sharon Kleyne is an internationally recognized entrepreneur, water and health advocate, and Founder of Bio-Logic Aqua Research and Save a Child’s Life Foundation. To hear the complete show, go to

Sharon Kleyn: Dr. Eugene Helveston is a retired Ophthalmology Professor at Indiana University Medical School. Since 2000, he has volunteered for ORBIS International, which conducts pediatric eye care screening, training and sight preservation programs in third world countries. Does ORBIS have programs in the US, Dr. Helveston?

Dr. Eugene Helveston: Only recruitment programs. We enlist eye care professionals to travel overseas to help reduce eye diseases such as dry eye and preventable blindness.

S: What is the status of eye care education and children’s sight preservation worldwide?

E: Most children are born with normal vision but immature eyes. Development takes place rapidly and naturally and parents usually don’t pay much attention. But things can go wrong very fast. Parents must be educated to detect eye health problems early, such as poor vision and dry eye.

S: What are the signals of good eyesight in newborns?

E: The cornea should be naturally clear, glistening and bright, with no mucus or mottled spots. The tear film should look normal, with no dry eye symptoms.

S: Explain about the tear film.

E: The tear film is the primary vehicle for moistening and light refraction and it maintains perfect eye clarity. It should contain sufficient natural water not look dry or mottled, which are symptoms of dry eye. Very few parents are aware of this.

S: What are other things to look for?

E: A white reflection appearing inside the eye, called a “cat’s eye.” This is the earliest sign of retinal blastoma and it infects one in 18,000 to 20,000 children. It not only causes blindness, it is lethal if not treated.

S: Are there dry eye or vision symptoms related to the skin around the eye?

E: Yes, especially in older children, toddlers and preschoolers. Parents should look for squinting and trouble seeing but may miss this because to the child, this is perfectly normal.

S: Yes, we interviewed Dr. Marguerite McDonald a few weeks ago, who said that she was nearly blind as a child but was able to compensate and it was two years before her parents noticed.

E: That’s common. I’ve often fitted children with glasses and had them tell me that they never noticed tree leaves before.

S: What should US parents look for?

E: Eyes should be symmetrical and moist, with no signs of dry eye or abnormality. They should focus within a few weeks and be able to follow a finger. The child should be aware of their environment. There should be no excessive tears, and no cataracts or tumors. Visual acuity should be checked fairly young.

S: Tell us more about ORBIS.

E: One-half of the world’s 160,000 ophthalmologists live in developed countries. The other half are in dire need of equipment, education and a more enlightened population. ORBIS has permanent staff in India, Viet Nam, Bangladesh, China and Ethiopia. We also operate the “Flying Eye Hospital,” a DC-10 airliner. In each country, we put together an educational and service sight preservation program to meet local needs needs.

S: What have you learned about eye care and dry eye China?

E: The natural incidence of nearsightedness in Chinese children is much higher than in the US – about 15%. This may be genetic, or it may be environmental or cultural.

S: Or it could be due to dry eye from dry air and extreme pollution. What do you do for ORBIS?

E: I set up standards of care, locate equipment, and select key doctors in target countries to train in modern sight preservation practice and diagnosis.

S: Is the US the most advanced country for eye care?

E: Without question.

S: Is increasing dry air and dry eye a factor in the third world countries?

E: It can be. In Nepal, for example, the elevation of many towns is over 10,000 feet, so air is naturally very dry and dry eye is common. Altitude and dry air can affect vision and accelerate childhood eye diseases.

S: One of my eye health recommendations is to drink sufficient natural water to prevent dry eye. Do you have any nutritional advice?

E: The majority of preventable blindness, which can be as much as 75% of all blindness, has to do with vitamin A deficiency. This is most common in sub-Saharan Africa, India and China.

S: What are some vitamin A foods?

E: Natural foods such as whole grain rice, fresh vegetables, whole wheat. Rubella vaccinations are also important. Folk remedies such as rubbing mud in the eyes should be avoided.

Dr. Robert Latkany, author of The Dry Eye Remedy

Guest: Robert Latkany, MD (New York, NY), Ophthalmologist and author, The Dry Eye Remedy (Hatherleigh Press 2007)

I was pleased to have dry eye pioneer Dr. Robert Latkany as a guest on the Sharon Kleyne Hour – Power of Water. Dr. Latkany is reportedly the only ophthalmologist specializing in dry eye disease and tear film hydration. He is author of the best selling book, The Dry Eye Remedy.

I became aware of Dr. Latkany after reading an article about his book and his New York City medical practice in the Wall Street Journal (“A Closer Look at Dry Eye” by Rhonda Rundle, May 1, 2007). Nature’s Tears EyeMist, an all-natural hand-held moisturizing mist for dry eye hydration, was mentioned. So naturally, I called him and we became allies in this important cause.

Dr. Latkany and I agree on the worldwide need for dry eye treatment alternatives, prevention and education. There is also an urgent need to address the plight of the thousands who go blind every day from dry eye disease, dry air and inadequate water and sanitation.

According to Dr. Latkany, dry eye disease and tear film dehydration are the #1 reason for US eye doctor (ophthalmologist) visits. The condition can become extremely serious, especially as we grow older. Since most people with dry eye disease don’t experience severe symptoms, it often goes undiagnosed. Primary symptoms of chronic dry eye include briefly blurred vision, fatigue, increased allergic sensitivity, burning eyes, red eye and frequent headaches.

Untreated chronic dry eye disease, according to Dr. Latkany, could result in loss of eyesight. Dry eye disease and tear film dehydration can cause cracking and scarring of the cornea, leading to infection and other eye diseases. Allergies can contribute to dry eye symptoms but so can the antihistamines commonly found in eye drops.

I asked Dr. Latkany about dry eye and computers, just as I asked Dr. Marguerite McDonald and Dr. Philip Paden. He said that people who spend all day at the computer often blink far less frequently. As a result, more tear film water (moisture) evaporates and the “blink muscles” weaken.

I discussed my own research with Dr. Latkany, previously shared on the Sharon Kleyne Hour. Many dry air factors cause dry eye, red eye, burning eyes and tear film dehydration. Dry air indoors is a major cause of dry eye, especially dry air from forced-air heating and cooling, and man made household chemicals can cause dry eye. I suggest all-natural alternatives such as a mist humidifier or air purifier, or simply setting out bowls of water or opening a window (unless the air outside is extremely dry or polluted).

I observed that people take daily care of their teeth, hair and skin and wondered why they take eye hydration for granted. Dr. Latkany believes the name “dry eye” just doesn’t sound like a disease. As for treatment alternatives, Dr. Latkany advises all-natural alternatives over dye drops, such as drinking lots of water, exercising regularly, taking care of your health and hydration and above all, educating yourself about dry eye and eye care treatment alternatives. We also discussed the importance of Nature’s Tears EyeMist and eye misting and moisturizing in general for dry eye, red eye and burning eyes, as reported in the Wall Street Journal article.

Dr. Marguerite McDonald on Dry Eye Causes and Treatment

Dry Eye, Dry Air and Dehydration Disease

Guest: Marguerite McDonald, MD, (Long Island, NY), Lasik pioneer, Ophthalmologist and dry eye consultant.

Dr. Marguerite McDonald

(Reference: McDonald, M, MD, “The Forgotten Symptom: Dry Eye in Cataract Patients,” Ophthalmology Times, October 1, 2008)

Dry eye and tear film moisture loss are early symptoms of dry air, global drying and dehydration disease. Untreated dry eye can cause corneal ulceration and scarring, eye allergies, eye inflammation, numerous eye diseases and blindness. Because The Sharon Kleyne Hour Power of Water, on World Talk Radio, is devoted to the study of dry air, dehydration diseases and health as part of the power of water; dry eye is a frequent topic. Dry eye guest experts have included Dr. Marguerite McDonald, Dr. Philip Paden, Dr. Robert Latkany, Dr. Ilene Gipson and others.
