Hypertension, or high blood pressure, is a persistent blood pressure above 90 mm Hg between the heart beats (diastolic) or over 140 mm Hg at the beats (systolic). The blood pressure varies naturally in response to stress and physical work load. Therefore the blood pressure shall be measured in a relaxed situation and several times before this diagnosis is certain.
Hypertension does not in itself give dramatic symptoms, but it is dangerous because it causes a highly increased risk for heart infarction, stroke and renal failure.

THE PREVALENCE OF HYPERTENSION
One out of six persons is hypertensive. Most persons suffering from hypertension is over the age of 35. Still 6% of teenagers are hypertensive and also 1% of every child.

THE SYMPTOMS AND CONSEQUENCES OF HYPERTENSION
Hypertension is often without symptoms. By mild hypertension, flushing and headache can occur.
More serious hypertension gives symptoms like: Fatigue, dizziness, palpitations, tachycardia (rapid heart rate) and nosebleeds.
Extreme hypertension gives morning headache, blurred vision, dyspnoea (breathing difficulties) and elevated values of certain components in the blood, like urea and serum creatinine.
Hypertension will in the long run hurt the blood vessels, and serious hypertension can do extensive damage to the blood vessels in a few months or years.
The damaged blood vessels will impair the blood flow. They can also rupture causing a bleeding or be clogged by a blood clot that shuts out the blood flow and causes tissue damage. These things can occur in the brain, causing a stroke, in the heart causing heart infarction or in the kidneys with renal failure as a consequence.
A renal failure will in the next turn cause the hypertension to aggarvate, partly because a damaged kidney will not manage to secrete water and salt well enough, and partly because a kidney that do not get enough blood will start a hormonal mechanism that induces the kidney to actively hold back salt and water.

THE MECHANISMS AND CAUSES OF HYPERTENSION
The direct mechanisms causing hypertension is one or more of these factors:
- An increased tension in the blood vessel walls.
- An increased blood volume caused by elevated levels of salt and lipids in the blood holding back water.
- Hardened and inelastic blood vessels caused by arteriosclerosis.
The primary causes behind these mechanisms are not fully understood, but these factors contribute to causing hypertension:
- A high consume of salt
- A high fat consume.
- Stress at work and in the daily life.
- Smoking.
- Over-weight
- Lack of exercise.
- Kidney failure.

LIFESTYLE MEASURES TO PREVENT AND TREAT HYPERTENSION
Lifestyle measures shall always be a component of the hypertension treatment. Sometimes such measures are enough to cure the condition. Those measures are:
- Reducing salt consume.
- Reduction of the consume of fat, and especially saturated fat.
- Weight reduction.
- Relaxing and stress reduction techiques, for example meditation and autogenic training.
- Regular exercise.
SPECIAL FOOD TYPES THAT REDUCE THE BLOOD PRESSURE
Research projects suggest that the following food types reduce blood pressure.
- Fish oil and fat fish. The working substances seem to be the omega-3 unsaturated fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The effect from fish oil seems to cease when the fish oil supplements are stopped.
-Olive oil, especially olive oil of the quality extra virgin.

NATURAL SUPPLEMENTS TO HELP AGAINST HYPERTENSION
Natural supplements to treat hypertension exist. These supplements reduce blood pressure by lowering the cholesterol and lipid content in the blood, by preventing oxidation of tissue components by free radicals, and by helping damaged blood vessels to heal. Examples of ingredients having these effects are vitamin B3, inositol, turmenic extract and gum guggul extract.
They may also contain Ingredients giving a direct anti-hypertensive effect, like potassium, magnesium, calcium, vitamin C and fatty acids from marine sources.

MEDICAL TREATMENT OF HYPERTENSION
When lifestyle measures and supplements are not enough to cure the condition, medical treatment must be applied.
Diuretics, or medicines to increase the urine production, are used to decrease the water content in the blood vessels, and thereby reduce the pressure in the vessels. When the water content is lowered, the heart does not need to pump so hard any more, and this will also reduce the pressure.
Beta-adrenergic blockers are another group of medicines to treat hypertension. This group of medicines block the signals that hormones and neurotransmitters give to the vessel walls, and the vessel walls then relax. They also slow down the heart rate to give a lower pressure exerted by the heart upon the blood.

Green Tea Benefits & Uses
Green Tea:
Since the first cup of green tea almost five thousand years ago, the popularity of tea has grown to the point that it is now the second most consumed beverage in the world. Only water is more popular. Today, scientific research in both Asia and the west is providing hard evidence for the health benefits long associated with drinking green tea. For example, in 1994 the Journal of the National Cancer Institute published the results of an epidemiological study indicating that drinking green tea reduced the risk of esophageal cancer in Chinese men and women by nearly sixty percent. University of Purdue researchers recently concluded that a compound in green tea inhibits the growth of cancer cells. There is also research indicating that drinking green tea lowers total cholesterol levels, as well as improving the ratio of good (HDL) cholesterol to bad (LDL) cholesterol.Symptoms of Green Tea:
There are just a few medical conditions in which drinking green tea is reputed to be helpful:
1.Cancer 2.Rheumatoid arthritis 3.High cholesterol levels 4.Cariovascular disease 5.Infection 6.Impaired immune function
Prevention:
The secret of green tea lies in the fact it is rich in catechin polyphenols, particularly epigallocatechin gallate (EGCG). EGCG is a powerful anti-oxidant: besides inhibiting the growth of cancer cells, it kills cancer cells without harming healthy tissue. It has also been effective in lowering LDL cholesterol levels, and inhibiting the abnormal formation of blood clots. The latter takes on added importance when you consider that thrombosis (the formation of abnormal blood clots) is the leading cause of heart attacks and stroke.
Green tea leaves are steamed, which prevents the EGCG compound from being oxidized. By contrast, black and oolong tea leaves are made from fermented leaves, which results in the EGCG being converted into other compounds that are not nearly as effective in preventing and fighting various diseases.
Benefits & Effect Green Tea:
Green tea can even help prevent tooth decay! Just as its bacteria-destroying abilities can help prevent food poisoning, it can also kill the bacteria that causes dental plaque. Meanwhile, skin preparations containing green tea - from deodorants to creams - are starting to appear on the market.
To date, the only negative side effect reported from drinking green tea is insomnia due to the fact that it contains caffeine. However, green tea contains less caffeine than coffee: there are approximately thirty to sixty mg. of caffeine in six - eight ounces of tea, compared to over one-hundred mg. in eight ounces of coffee.


Take care of your teeth
A smile is a very important part of most people's live for several reasons. One reason is confidence. A person with nice teeth will be a lot more confident in social situations such as job fairs and parties, whereas a person with bad teeth may be less confident and people will notice that. Another reason taking care of your teeth is important is because even though there are many procedures that can help fix them, many do not have a very natural look such as veneers.
Below are some things that anyone can do whether young or old to keep their teeth in good condition.
1. Brush and floss twice each day.
2. Cut back on soda and drink more water. Soda decays the teeth very badly if consumed to often. Drinking water provides fluoride and helps to prevent cavities.
3. Cut back on candy and other sweets. Candy and other also decay the teeth, instead try eating more fruit.
4. Where a mouth guard while playing sports. That will protect your teeth in the case of a hard shot to the mouth.
Doing the four things listed above can easily prevent teeth from becoming decayed and being knocked out or chipped during sports.
