Eye Dehydration and Re-hydration

19 Oct

Post by Sharon Kleyne, Research Director, Bio-Logic Aqua Research (Guest blogger)

“Hydration,” refers to the natural moisture in skin, eyes, breathing passages, etc., essential for healthy functioning. “Dehydration” is the loss of that natural moisture, often to the detriment of health. Recent discoveries offer new ways for individuals to re-hydrate their eyes and skin.

Loss of moisture in the skin, eyes and breathing passages can weaken resistance, impair functioning and lead to numerous diseases and/or health conditions. Dehydration related health issues include dry eye syndrome, dry and/or chapped skin, dry mouth, computer eye strain (computer vision syndrome), contact lens dryness, allergies, viral and sunburn sensitivity, adult acne, dermatitis, Sjogren’s syndrome, lupus, scleroderma, and cancers of the skin and eyes.

In the past 20 years, the incidence of dehydration related health problems has increased dramatically. Bio-Logic Aqua Research attributes this to multiple causes:

  • Indoor “climate control” conditions such as forced-air heating and cooling, insulated walls and windows, low indoor humidity, etc. This includes cars as well as buildings, and especially includes jet airline travel (cabin humidity may be as low as 3%).
  • Lifestyle choices and personal habits, including contact lenses, excessive computer use, participation in extreme sports, caffeine and alcohol consumption, not drinking enough water, too much time spent indoors, cigarette smoking, medications, etc.
  • Smoke, dust, wind, extreme heat and cold and other outdoor conditions.
  • “Global drying,” resulting in too little unpolluted and health promoting humidity in the air. Global drying is caused by rapid population growth, air and water pollution, loss of fresh water as land is developed, and possibly global warming and ozone depletion.

Re-hydration is accomplished by:

  • Avoiding the above high-risk situations whenever possible and/or taking steps to counteract dryness (such as placing plants and/or dishes of water in a too-dry room).
  • Being aware at all times of the condition of your eyes and skin.
  • Taking positive steps to replace the lost eye and skin moisture, as described in this series.

Sight Preservation

11 Oct

There are an estimated 37 million blind people worldwide, the vast majority in Africa and Asia, of which 75% is considered preventable (the biggest culprits are cataracts and glaucoma).[2] The U.S. has 1.3 million legally blind (20/200 or worse) individuals.[3]

Even as scientists develop LASIK surgeries, corneal transplants and other heroic procedures to preserve, protect and restore vision, global vision threats are increasing. The air is becoming hotter, dryer and more polluted, fresh potable water is becoming scarcer, solar radiation is increasing because of ozone layer deterioration, increased population means increased vectors to spread disease, etc.[4]

Those most affected, obviously, are those with the least access to conveniences like fresh water, indoor humidifiers, sunglasses and advances in medical technology.[5] Despite trillions spent on research, modern technology itself can pose unintended threats to vision. Forced-air heating and cooling, insulated wall and windows, and numerous household chemicals can cause eye irritation and dry eye and ultimately threaten vision.[6] Eventually, the growing global vision threat could affect us all.

The good news is that we are not helpless. With education and a few simple precautionary steps, we can learn to protect ourselves and preserve our precious vision.

What is “sight preservation?” “Sight” is defined in the Webster’s New Collegiate Dictionary as “the animal sense of which the end organ is the eye, and by which the position, shape and color of objects are perceived.”[7] “Preservation” is defined as “keeping safe from injury, harm or destruction. Keeping alive, intact or free from deterioration” (as opposed to “restoration”).[8]

Numerous organizations worldwide and in the United States are dedicated to sight preservation. Orbis International does excellent work in the world’s developing countries to provide medical treatment, teach proper vision care and help make available adequate water and nutrition.[9] The Lions Clubs International is also involved in sight preservation, as are numerous other national and international medical, vision and community health organizations.[10]

For the average U.S. resident, with access to medical care and good water, in an age of global warming and drying, we offer the following simple suggestions: Continue reading
