Неврозы – Neuroses

1) Headache

Besides eyestrain, long hours in front of a VDT can also lead to headaches. Rest breaks are important as a means of prevention, and some experts recommend that you wear some type of tinted glasses to reduce the risk of headache from staring at a bright VDT screen.

2) Neck Pain

Many people who work with a VDT all day end up with neck spasms and muscle fatigue. That’s usually because the terminal is positioned in such a way that these people have to look up or down all day. Experts recommend that you position your VDT at eye level to avoid the discomfort of neck pain. The height of your desk should also enable you to sit at your keyboard so that your lower arms form a 70 to 90 degree angle to your upper body. The monitor itself should be within a 30 degree viewing angle of your direct line of vision.

3) Backache

Poor posture while working long hours at a computer can contribute to backache. To avoid this problem, you should adjust your chair to suit your height at the desk and to provide adequate support for your lower back. The height of your chair should allow you to sit in a relaxed position with your feet firmly on the floor and your back straight.

Here are several ways you can avoid an overdose of vitamin A:

1) To supplement your body’s store of vitamin A, take carotene supplements instead of vitamin A supplements. Consult with your physician for his or her advice.

2) If you take a vitamin supplement, be sure you never exceed the RDA for vitamin A (see chapter 2) unless you have your doctor’s permission.

3) Don’t take vitamin A supplements if you are currently taking fish oil or cod liver oil supplements. Both of these contain large amounts of vitamin A, and the result could be an overdose. Because of their high level of vitamin A, you should use cod liver oil and other fish oil supplements only under a doctor’s supervision.

4) Don’t take vitamin A supplements if you are using birth control pills, unless you have your doctor’s permission. Some studies indicate that women taking birth control pills sometimes experience an increase in their levels of vitamin A.

5) You shouldn’t take vitamin A supplements if you are currently taking prescription drugs that are made from vitamin A. There are two drugs in use today which are derived from vitamin A— Accutane for acne and Tigason for psoriasis. Retin A is a vitamin A ointment which is used for smoothing out wrinkles in skin which has been damaged by prolonged exposure to the sun and aging.

Fish oil contains a special type of unsaturated fat called omega-3. Research has shown that fish oil may be effective in counteracting a high-cholesterol diet by lowering blood levels of very-low-density cholesterol and triglycerides. There seems to be no disagreement that fish is good food, but most authorities, including The American Heart Association and The National Heart, Lung, and Blood Institute, strongly recommend that you get fish oil from fish rather than through the use of fish-oil capsules.

The latest research hasn’t show how much fish oil you need to get the beneficial effects, but there are indications that certain doses of fish oil may be harmful. In any event, eating fish as much as three times a week may indeed be good for you, but since precise dosages are not known, it’s best that you avoid fish-oil capsules, and get youi oil strictly from the fish.

The Healthest Type Of Fish You Can Buy

A low-dosage hormone pill, known as melatonin, may reset the body’s internal time clock and help cure «night owl» insomnia. The pill may also serve as prevention for jet lag.

According to researchers, the hormone melatonin brings on drowsiness and is secreted by the brain naturally overnight. However a pill with 0.5 milligram of melatonin, taken during the day, may «trick» the body clock into thinking that it is nighttime.

When tne pill is taken in the late afternoon, the body tends to think that night time has Come on, and begins to get sleepy.

In order to prevent jet lag, the hormone pill would most likely be taken for a few days beginning the day before departure. Its use would be combined with exposure to outdoor light at the travelers destination.

Still in the experimental stages, the hormone pill is not yet available. However, researchers say that if their findings continue to be positive, it could be available on the market in a few years.

The study, reported in Archives of Ophthalmology, while not conclusive, does lend more support to the importance of proper lens care.
