Water and Eye Health

Water and Eye Health

Nutrients and minerals cannot be transported to other organs without water

Many people use eye drops to alleviate dry eyes but there is another way to ease the dry eye syndrome; drink more water. A hydrated body can also affect the eyes since they are surrounded by fluid and need water to keep a healthy balance for sight. The fluid protects the eyes by washing away dirt and dust every time we blink. Water also allows us to be more energetic as it assists in proper cellular function and supports normal cell structure. Without water, nutrients and minerals cannot be transported to other organs.

Vision is affected on many levels especially since the eyes are an extension of the brain which needs a good amount of water to aid proper function. Brain tissue is about 85% water so this is why it’s necessary to keep the brain hydrated. If you’re dehydrated, brain fog might set in or you might experience a lack of focusing and lightheadedness. Keeping the brain healthy affects the eyes as well since it receives almost 20% of blood flow. Eyes are an extension of the brain so this is why it’s important to keep the fluid levels in your body topped up.

Dehydration also leads to thicker blood which slows down the blood flow to other parts of the body. Essentially, a person should drink enough water at a ratio of half of his or her body weight so if you’re a woman who weighs 130 lbs then you should drink 65 ounces of water per day which is approximately 8 ounces.

It’s important to drink on a consistent basis during the day rather than gulping a lot of water at once during a short period of time. This avoids dehydration throughout the day and keeps the body hydrated on a consistent basis. Balance is key to keeping the body hydrated throughout the day. If you have a dry mouth constantly, dry skin, lack of urination and dry eyes, these are significant signs that you’re not drinking enough water.

If you’re not sure about how dehydrated you are, also look at your urine color. This article is helpful in revealing the various shades of yellow your urine can be, illustrating how well you’re hydrated. If your urine is a darker yellow, the more dehydrated you are, whereas a lighter shade of yellow shows that you’re hydrated enough.

The body will give you signals that it needs more water which may include other symptoms like muscle cramps, headache, lightheadedness, sleepiness, and lack of tear production. Having no tears means that the eyes are no longer lubricated and dehydration is severe. Dry eye syndrome can also be a result of eye strain. Properly hydrating the body can bring the body out of a dehydrated state and a word of caution about dehydration; it can be life-threatening if it’s severe.

Drink water before meals and exercise to help with digestion as well as replenishing what has been lost in the body through sweating. Avoid drinking too many soft drinks, tea, or coffee since these drinks can also cause dehydration for the eyes and other organs. It’s important to drink water upon waking as well so that hydration begins before having breakfast. If the eyes are competing for hydration with other organs, the dry eye syndrome is only one result.

In this video Drinking Water for Eye Health at the Richie Eye Clinic in Faribault, MN, USA, Dr. Michael Richie explains the importance of drinking enough water to maintain eye health. Drinking other fluids don’t count in hydrating the body. He specifically instructs how much water to drink in order to maintain healthy eyes.

In another video called the Dry Eyes Osmolarity Test, Dr. Richie describes a new test that diagnoses dry eye syndrome. As a result of doing this test, the Dry Eye Disease Severity Scale can measure the severity of dry eye syndrome in a patient. If there is more concentration of salt in your tears, it’s a sign that you have less water in your tears, therefore less mucous and oil which is a sign of dehydration.
