What Your Eyes Say About Your Health

1. Bloody eye. The eye’s transparent outer layer, called the conjunctiva, is nourished by numerous tiny blood vessels. If these burst, blood may pool on the white of the eye (sclera). A subconjunctival hemorrhage, as it is known among doctors, can be caused by a blow to the eye but in most cases has no obvious cause. In rare instances, a subconjunctival hemorrhage can be a sign of severe high blood pressure or a platelet disorder, which can interfere with clotting, Williams tells WebMD.

2. Bulging eyes. Though prominent eyes may simply be a family trait, eyes that appear to bulge may be evidence of thyroid disease. Abnormal levels of thyroid hormone cause tissues surrounding the eye to swell, making it appear that the eye is bulging. 

3. Droopy eyelid. This condition, known among doctors as ptosis, can be simply a sign of aging. But in rare cases it is evidence of a brain tumor or a neuromuscular disease known as myasthenia gravis (MG), Iwach says. MG is an autoimmune disorder that weakens muscles throughout the body.

4. Pupil abnormalities. The pupils of healthy people are usually (but not always) symmetrical. They’re usually of the same size, and they usually show the same reaction upon exposure to light. If one pupil is bigger than the other, or if one pupil shrinks less, or more slowly, on exposure to light, there could be an underlying medical problem. Possibilities include stroke, brain, or optic nerve tumor, brain aneurysm, syphilis, and multiple sclerosis (MS). Finally, many medications -- including illicit drugs -- can cause the pupils to appear unusually small or large, says Peter Kastl, MD, PhD, professor of ophthalmology, Tulane University School of Medicine. 

5. Rings on the cornea. A rare hereditary disorder known as Wilson’s disease can cause copper to accumulate in various tissues, including those in the brain and liver. Copper deposits sometimes form on the inner surface of the cornea (though they appear to a casual observer to be on the iris, the colored disk that surrounds the pupil). These “Kayser-Fleischer rings” are themselves harmless. But without appropriate treatment, Wilson’s disease can be fatal.
Thickened eyelid. In very rare cases, a thickening or deformation of the eyelid is a sign of neurofibromatosis, a rare hereditary disorder marked by the growth of tumors along nerve fibers (the tumors themselves are called plexiform neurofibromas). Joseph Merrick, the 19th Century Englishman known as the Elephant Man, was long thought to have had neurofibromatosis. But experts now believe that he suffered from another rare condition known as Proteus Syndrome.

6. Yellow eyes. Diseases of the liver, including hepatitis and cirrhosis, can turn the scleras yellow. The color is caused by the buildup of bilirubin, a compound created by the breakdown of hemoglobin, the oxygen-carrying molecule inside red blood cells. The medical term for yellow eyes is scleral icterus -- even though it’s not actually the scleras that turn yellow, but the conjunctiva.

Top 10 Food For Healthy Hair

1: Salmon
When it comes to foods that pack a beauty punch, it's hard to beat salmon. Loaded with omega-3 fatty acids, this high-quality protein source is also filled with vitamin B-12 and iron.
"Essential omega-3 fatty acids are needed to support scalp health," says Andrea Giancoli, MPH, RD, a dietitian in Los Angeles and a spokeswoman for the American Dietetic Association. "A deficiency can result in a dry scalp and thus hair, giving it a dull look. "Vegetarian? Include one or two tablespoons of ground flaxseed in your daily diet for some plant-based omega-3 fats

2: Dark Green Vegetables

Popeye the Sailor Man didn't eat all that spinach for healthy hair, but he could have. Spinach, like broccoli and Swiss chard, is an excellent source of vitamins A and C, which your body needs to produce sebum. The oily substance, secreted by your hair follicles, is the body's natural hair conditioner. Dark green vegetables also provide iron and calcium.

3: Beans

Beans, beans, they're good for your ... hair?
Yes, it's true. Legumes like kidney beans and lentils should be an important part of your hair-care diet. Not only do they provide plentiful protein to promote hair growth, but ample iron, zinc, and biotin. While rare, biotin deficiencies can result in brittle hair.
Blatner, who is also a spokeswoman for the American Dietetic Association, recommends three or more cups of lentils or beans each week.

4: Nuts

Do you go nuts for thick, shiny hair? You should. Brazil nuts are one of nature's best sources of selenium, an important mineral for the health of your scalp. Walnuts contain alpha-linolenic acid, an omega-3 fatty acid that may help condition your hair. They are also a terrific source of zinc, as are cashews, pecans, and almonds. A zinc deficiency can lead to hair shedding, so make sure nuts are a regular on your healthy hair menu.

5: Poultry

Chickens and turkeys may have feathers, but the high-quality protein they provide will help give you the healthy hair you crave. "Without adequate protein or with low-quality protein, one can experience weak brittle hair, while a profound protein deficiency can result in loss of hair color," Giancoli tells WebMD. Poultry also provides iron with a high degree of bioavailability, meaning your body can easily reap its benefits.

6: Eggs

When it comes to healthy hair, it doesn't matter whether you like your eggs scrambled, fried, or over easy. However they're served up, eggs are one of the best protein sources you can find. They also contain biotin and vitamin B-12, which are important beauty nutrients.

7: Whole Grains

Sink your teeth into hearty whole grains, including whole-wheat bread and fortified whole-grain breakfast cereals, for a hair-healthy dose of zinc, iron, and B vitamins. A whole-grain snack can also be a great go-to food when your energy is zapped halfway through the afternoon, and you've still got hours to go before dinner.

8: Oysters

Oysters may be better known for their reputation as an aphrodisiac, but they can also lead to healthy hair -- and who doesn't love that?
The key to their love and hair-boosting abilities is zinc -- a powerful antioxidant.
If oysters don't make a regular appearance on your dinner plate, don't despair. In addition to getting it from whole grains and nuts, you can also get zinc from beef and lamb.

9: Low-Fat Dairy Products

Low-fat dairy products like skim milk and yogurt are great sources of calcium, an important mineral for hair growth. They also contain whey and casein, two high-quality protein sources.
For some healthy hair foods "to-go," try throwing a yogurt or cottage cheese cup in your bag when you head out in the morning to snack on later in the day. You can even boost their hair benefits by stirring in a couple of tablespoons of ground flaxseeds or walnuts for omega-3 fatty acids and zinc.

10: Carrots

Carrots are an excellent source of vitamin A, which promotes a healthy scalp along with good vision.
Since a healthy scalp is essential for a shiny, well-conditioned head of hair, you'd be wise to include carrots in your diet as snacks or toppings on your salad.

10 Tips to Prevent motion Sickness

Motion sickness , sometimes referred to as sea sickness or car sickness, is a very common disturbance of the inner ear that is caused by repeated motion. In addition to sea travel, motion sickness can develop from the movement of a car or from turbulence in an airplane. The symptoms of motion sickness are nausea, vomiting, dizziness, sweating, and a sense of feeling unwell. These symptoms arise from the inner ear (labyrinth) due to changes in one's sense of balance and equilibrium.

While it may be impossible to prevent all cases of motion sickness, the following tips can help you prevent or lessen the severity of motion sickness:
1. Watch your consumption of foods, drinks, and alcohol before and during travel. Avoid excessive alcohol and foods or liquids that "do not agree with you" or make you feel unusually full. Heavy, spicy, or fat-rich foods may worsen motion sickness in some people.
2. Avoiding strong food odors may also help prevent nausea.
3. Try to choose a seat where you will experience the least motion. The middle of an airplane over the wing is the calmest area of an airplane. On a ship, those in lower level cabins near the center of a ship generally experience less motion than passengers in higher or outer cabins.
4. Do not sit facing backwards from your direction of travel.
5. Sit in the front seat of a car.
6. Do not read while traveling if you are prone to motion sickness.
7. When traveling by car or boat, it can sometimes help to keep your gaze fixed on the horizon or on a fixed point.
8. Open a vent or source of fresh air if possible.
9. Isolate yourself from others who may be suffering from motion sickness. Hearing others talk about motion sickness or seeing others becoming ill can sometimes make you feel ill yourself.
10. The over-the-counter medication meclizine (Bonine, Antivert, Dramamine) can be a very effective preventive measure for short trips or for mild cases of motion sickness. Your doctor also may choose to prescribe medications for longer trips or if you repeatedly develop severe motion sickness. One example of a prescription medication is a patch containing scopolamine (Transderm-Scop) that often is effective in preventing motion sickness. Remember that scopolamine can cause drowsiness and has other side effects, and its use should be discussed with your physician prior to your trip.
