5 Great Ways To Lower Blood Pressure Quickly
For people with high blood pressure, medication sometimes is not sufficient to lower it to healthy levels. Consequently, they have to find additional ways help lower their blood pressure. Uncontrolled and prolonged high blood pressure can lead to serious complications; including, kidney failure, heart attack, and stroke. That is why you need to do every little bit you can to bring it under control. Here are some natural ways to lower your blood pressure that are easy to incorporate into your daily routine.
1. A Piece Of Dark Chocolate Will Keep The Doctor Away.
According to recent report in the Hypertension: Journal of the American Heart Association, eating a small piece of dark chocolate everyday contributed to chemical changes in the body that help dilate blood vessels and lower blood pressure. Several research point to the conclusion that the antioxidant-rich compound found in dark chocolate known as flavonoids, have a healthy effect on blood vessels as well as glucose metabolism.
Even better news for chocolate lovers is the fact that dark chocolate contains more flavoniods than any other food; including green tea, red wine, and blueberries. A little dark chocolate is good for you, but a lot of it is not because chocolate is high in calories. Also, to obtain the blood pressure lowering effect of dark chocolate, you need to look for one that has at least 70 percent cocoa content. Dark chocolate is delicious but sometimes, it may be a bit bitter so, you may have to try different brands until you find one that you really like.
2. Potassium: A Magic Mineral.
Potassium is a key nutrient in maintaining the electrolyte balance which regulates heart and muscle contraction. It also plays an important role in maintaining proper fluid exchange. A study conducted at Duke University shows that daily intake of Potassium supplements can significantly reduce high blood pressure. African-Americans showed the biggest drop. Their blood pressure went down almost 20 points, causing the speculation that this sub-group might be particularly sensitive to the blood pressure lowering effects of potassium.
It is recommended that you try to get your potassium from food. Dietary sources of potassium include apple juice, apricots, avocado, bananas, legumes, beets, cantaloupe, carrots, oranges, pears, white and sweet potatoes, raisins, salmon, sardines, watermelon, and winter squash.
3. Water: Nature's Miracle Medicine
When your body is in a state of dehydration, your blood pressure will increase dramatically. In fact chronic dehydration is the cause of chronic high blood pressure. Dr. Bathmanghelidj, the author of You're Not Sick, You're Thirsty, says that when the body is lacking water, it attempts to hold on to the available water supplies by retaining salt. When the body starts to retain water instead of letting it flow normally, blood pressure rises. However, this increased water retention is simply a preventive measure the body uses to protect the vital cells within it from becoming totally dehydrated. Water is one of the most effective ways to lower blood pressure.
Adequate water intake, and a bit of good pure natural salt such as Himalayan Crystal salt, will balance the fluid intake inside and outside the cells. This may sound contradictory to what you havebeen told, but salt is essential for life, we cannot live without it. However, there is a big difference between the common processed salt most people are accustomed to, and pure natural Himalayan salt which contains 85 trace minerals that your body needs. Intake of Himalayan Crystal salt will regulate the water content throughout your body, and promote a healthy PH balance.
Make drinking adequate amounts of water a daily habit. Not only will you be lowering your blood pressure, but a lot of other body functions will improve. You will feel more alert and energetic, less depressed, your skin will glow, and those nagging aches and pain will go away.
4. Breathe Deep For Your Heart
New research indicates slow breathing may lower blood pressure, even if practiced for only a few minutes per day. Take a slow deep breath, expanding the diaphragm, and the abdomen then, exhale even slower making sure you empty all the air from the lungs. The goal is to develop a rhythmic slow, and deep breathing pattern of less than 10 breaths per minute.
At first, you may find it difficult to develop a rhythmic pattern, but as you continue to breath in, and out slowly, you will eventually develop a healthy breathing pattern. Breathing that slowly for a few minutes several times throughout the day is another way to lower blood pressure that many people find very effective.
5. Walking Is Good For You
Many of us live a very sedentary lifestyle. We sit down all day at work and then, we spend our time at home sitting down. Over time, this inactivity can lead to many health complications caused primarily by excess weight. The ongoing day-to-day strain that excess weight puts on the entire cardiovascular system is what causes blood pressure to reach dangerous heights. Exercise plays a key role in lowering high blood pressure; however, many people find it difficult to engage in a regular exercise program because of lack of time. The good news is that you're not required to do prolonged, and strenuous exercise to benefit from it.
A recent study published in the Journal of Epidemiology and Community Health revealed that as little as 30 minutes of walking three times a week, even if it was broken into 10-minute walks throughout the day, was enough to have a significant effect on lowering blood pressure, and weight loss.
The above 5 approaches are proven ways to lower blood pressure. However, consistency is the only way to benefit from them long term. Make them part of your daily lifestyle routine for a healthy heart, and normal blood pressure.

Ultraviolet Light and Tints - A Guide to Choosing Your Sunglasses
Light travels as electromagnetic waves, similar to the waves on the sea, with peaks and troughs. We specify the different colours of light by the wavelength of radiation they emit. (The wavelength is the distance between two adjacent peaks or troughs of that wave). As light has a very small wavelength, these measurements are extremely small and are measured in units called "nanometres" (nm), where a nanometre is one billionth of a metre!
Think of the colours of a rainbow, with red on the outer part of the curve and blue/violet on the inside. Red has a wavelength of 710nm, green is 500nm, and blue/violet is 400nm. So the wavelength is getting smaller as we pass from the red end of the visible spectrum through to the blue end. Ultra-violet lies beyond the blue/violet band, between wavelengths 400nm to 100nm, but the human eye cannot usually see light with a wavelength smaller than 400nm, making ultra-violet light invisible to us - so we call it ultraviolet radiation.
Although UV radiation is invisible to humans, many animals and insects can detect UV light, which they use in helping to find prey, etc. For example, kestrels can detect the UV light given off by the urine trails that field voles make as they move around, so from high up in the sky, when these birds of prey find many criss-crossing urine trails on the ground, this indicates a good place to hunt for the voles.
One possible reason why we cannot detect UV light is that if the crystalline lens in the human eye has evolved to only focus on a limited range of colours, this helps to give us a sharper image of what we see, whereas if we could focus over a larger range of wavelengths this could lead to chromatic aberration, a distortion of vision that would reduce image clarity.
Ultra-violet radiation can be divided into three main bands or groups, depending on wavelength :-
1. UVC radiation - 100 to 290nm
UVC rays are absorbed by the all-important ozone layer that surrounds the Earth as part of the outer atmosphere, thus preventing this radiation from reaching the ground.
2. UVB radiation - 290 to 320nm
UVB radiation is the most dangerous, as this is what can damage the eyes and cause sunburn to the skin. UVB is the cause of snow-blindness, where the radiation induces a photochemical reaction in the cornea and overlying conjunctiva after a few hours exposure, producing swelling of the cornea (oedema) and inflammation of the surrounding tissue. The swollen, oedematous cornea becomes cloudy - hence the blurred vision, and also very painful. There is photophobia (dislike of any exposure to light) and spasm of the eyelids. It usually lasts for a couple of days, and is only alleviated by using local anaesthetic drops, amethocaine 1%, to reduce the pain, and adrenalin drops 0.01% to relieve the congestion.
UVB radiation does not pass through glass, so a simple glass lens would prevent it from reaching the eye. Polycarbonate, a type of plastic sometimes used for spectacle and sunglass lenses, also cuts it out completely.
Some believe that regular exposure to UVB radiation can, over a period of time, contribute to cataract formation at an earlier age than normal, and may also cause the development of pterygia, which are growths of tissue that encroach over the cornea from the sides.
UVB radiation varies with the time of day, being most intense between 10am and 2pm, when the sun is at its brightest. It is stronger at high altitudes, and more intense near the equator, due to the more direct nature of the sun's rays in this region.
3. UVA radiation - 320 to 400nm
In contrast to UVB, which varies in intensity with the time of day, UVA radiation is more constant with less variation. Also it is not blocked by glass, and so can still pass through to reach the eye. However, the crystalline lens of the human eye absorbs most of the UVA radiation, so hardly any UVA is allowed to pass through to the back of the eye. There is no known evidence that UVA causes harm to the eye, although scientific opinion is still divided and under debate.
UVA radiation was originally thought to have only a minor effect on the skin, but recent studies have shown that whilst UVB causes damage to the surface layers of the skin as sunburn, the UVA penetrates into the deeper layers of the skin, causing damage further down.
Reflected Light
UV radiation not only reaches us directly from the sun, but a considerable portion is reflected from various surfaces around us, to reach our eyes and skin indirectly. Fresh new snow can reflect the most, with up to 80% reflected UV rays. On holiday on the beach, sand can reflect 15% UV light, along with concrete buildings and walls etc. A foaming, frothy sea reflects 25%, whereas still water and normal ground reflects around 10% UV radiation.
Choosing your Sunglass tint
Ideally, you should go for a tint that absorbs at least 98% of both UVA and UVB radiation. If you see a label "UV400", this means that all radiation up to 400nm (thus all UV radiation) is absorbed or blocked by the lens.
Dark grey, grey/green, or brown are the three main colours to choose from, and is a personal preference. I, myself, prefer grey or grey/green, because it seems to keep the colours true to life, but many people like brown because it can enhance the contrast and so help to make things appear sharper. Amber coloured tints are used to block out blue light, which again enhances contrast, so making the image sharper. Amber tints can therefore be used for skiing, sailing, flying, target shooting etc.
Lenses made from polycarbonate absorb most UV radiation, and wrap around designs are good for preventing light from entering the eye from the sides.
Children and UV Light
As UV damage tends to build up over many years of exposure, such as going on holiday to warm bright climates or playing outside on a sunny day, children and young adults are at particular risk, and you should always consider some sort of eyewear protection for them even though they seem to cope with bright light better than us adults (when playing at the seaside, for example). Wearing a peaked cap is not really enough protection, as a lot of the UV radiation is reflected off the ground (see earlier "reflected light") and straight into the eyes, especially on a sandy beach. Make sure the sunglasses have a full UV protection.
Advice on which tint to choose for sunglasses
Different coloured tints are available to enhance vision and improve visual comfort for many activities. Sunglasses are very important as they reduce glare and protect against harmful ultraviolet radiation. The main tints available can broadly be divided into neutral grey, polarising, yellow-brown, green, red and photochromic.
1. Neutral Grey
This filters out all wavelengths of light by an equal amount, and so colours appear more natural looking than with tints of other colours. Grey tints are good for activities where subtle colour differences are important, such as golf, mountaineering and skiing.
2. Polarised tints
Polarised tints are good for reducing glare from reflected light bouncing off surfaces such as water or wet roads, making them a good choice for fishing, water-sports, driving or cycling (on wet surfaces). However, polarised lenses might also reduce important details in skiing or golf.
3. Yellow / Amber tints
Yellow or amber tints help to increase contrast by blocking out the blue end of the visible spectrum, resulting in a reduction of blue light scatter. They enhance differences in contour and make things appear brighter in low light levels. This makes yellow or amber tints good for shooting, snow sports, driving or cycling.
4. Green tints
Green tints help to enhance the background, which makes them a particularly good choice for golf, tennis and some forms of shooting, where the object needs to show up against the background.
5. Red tints
Red tints enhance objects at the red end of the spectrum, and can be used in clay-pigeon shooting where the target is orange, in skiing to give contrast to the changes in reflected light, or in motor sports to reduce the reflected glare from the road.
6. Mirror tints
Mirror tints limit glare, increase absorption and reduce infra-red, thus reducing the build-up of heat. Mirror tints are good for snow sports, water sports, cycling and running.
7. Anti-reflection coatings
Anti-reflective coatings minimise lens reflections, especially from the back surface, and are recommended for racket sports, fishing, shooting and archery.
8. Photochromic tints
In photochromic tints the darkness of the tint changes according to the light levels, most commonly between around 20% to 80% transmission. Generally, two photochromic colours are available, brown or grey. Photochromic lenses are good for sports played in variable light levels, such as golf or tennis.
The following list gives a summary of suggested tints for different sports and activities:-
Cycling - polarising, yellow/amber Golf - green, neutral grey, yellow/amber, brown Shooting - reddish-brown, orange, yellow to brown, green Skiing - brown, red/orange, neutral grey Tennis - green Fishing - polarised Motor sports - polarising, yellow, red Water sports - polarising brown or grey Running - green, neutral grey Football, and fast moving ball sports - amber
I hope this guide has been of some use to you, but please remember that it is only a guide, so feel free to take it "lightly"(excuse the pun - I couldn't resist) as the colour of tint you choose for your sunglasses is very personal so if you prefer a certain colour of tint that falls outside of these guidelines - don't worry. As long as it blocks out all the ultraviolet light (UV 400) then that's all that matters. Enjoy your sunglasses!

How to Use a Tile and Grout Cleaning Machine
There are basically two different types of machines you can choose from to clean your tile & grout. Both of them are easy to use. You can use a steam cleaner, or a pressure washer.
A steam cleaner does more than just clean your grout; it also kills germs, mites, and bacteria. However, you need to be sure that you get a good steam cleaner to get the job done right. You should be using a steam cleaner that rates at 6 bars or better. A steam cleaner pressurizes the steam making it 180o C which is much hotter than waters normal boiling point of 100o C.
When steam has reached that point (of 180o C) it is called vaporized steam. It has about four to five percent of the moisture that regular steam has. This is a great advantage in grout cleaning because there is no water mess to clean up after cleaning the grout. A steam cleaner is a very effective tool to clean grout with. There are many professionals who provide this service, or you can rent the machine at a local rental shop and do the job yourself. Be sure though, that once the grout has been steam cleaned to apply grout sealer to keep the grout clean & maintained for much longer.
The other machine you can use for grout cleaning is a pressure washer. The greatest drawback to using a pressure washer over a steam cleaner is that a pressure washer uses a lot more water, so the clean up (after the cleaning) can take a while longer. As a result of that, you also will probably not be able to use it in all areas of your house. A pressure washer works great outside, and in baths & showers. You could even conceivably use it on bathroom floors (with a lot of care taken). However if you have tile flooring in any other areas of your house or tile in the kitchen, it would probably not be the best tool to use.
The advantage to using a pressure washer is that it is much faster to use than a steam cleaner for large areas, and it is easier to use vertically (like bath & shower walls). However, you have to be careful that you do not turn the pressure up too high so you don't damage the grout.
As with a steam cleaner, you can rent a pressure washer, or hire a professional to do the grout cleaning for you. They are cheap to rent, usually - and you could even buy a good quality one for 0 new. Note: When you are looking to rent or buy a pressure washer, PSI alone does not determine the speed. Talk to a salesperson to be sure you get the right pressure washer for your job.

Defense! Defense! Five Stocks That Win In Every Market Scenario
In a shaky stock market environment, there is no better place to turn than the defense contractors. Leading the S&P index by about 20% in 2008 (the 8th straight year of better relative performance), the so-called "big five" have their work cut out for them in 2008 and beyond. It is pretty much a foregone conclusion that defense spending will increase this year.
With high global threat levels, the United States defense budget has historically increased regardless of the presidential party in power. Don't listen to the fools that tell you a democrat president will cut the defense budget, that is simply not true. The funding put into homeland security as well as our defense budget is set to increase (President Bush recently introduced a .1 trillion dollar budget) regardless of the War on Terror's outcome, and the big five defense firms are set to benefit.
There are pros and cons to each of the main defense contractors, but I want to defend the notion that they are all winners in this environment. Which companies? I am talking about United Technologies, Lockheed Martin, General Dynamics, Raytheon and Northrop-Grumman.
United Technologies (NYSE: UTX)
UTX is the largest of the Defense companies, and offers a favorable mix of risk-reward at this point. A widely expected healthy first quarter could be a huge catalyst for the rest of the year. United Technologies does everything from industrial turbine engines to elevators, and it is this diversity that really makes them the General Electric of defense contractors. The weak dollar actually bolsters a potential earnings beat (%2B15%) for 2008, despite a rocky economy, because European sales account for about 25% of United Technologies' total.
Many investors have voiced concern over the recent announcement to acquire Diebold. I believe that speculation since the bid isn't likely to be hostile and the relative size of the expense is small on UTX's books. Other potential risks include a weakening in commercial construction markets and a slowing residential construction recovery, but I think that a strong aerospace backlog along with a geographic diversity balances their resume enough to ensure a strong year under even the worst conditions.
Lockheed Martin (NYSE: LMT)
Lockheed Martin is the kind of company that never gives you the value you want, but always performs with off the charts fundamentals and margins. I think a lot of analysts with HOLD ratings on the firm are underestimating LMT's ability to drive profit out of even the bleakest of market conditions. This company has the most risk behind a 2009 administration changeover, but the threat posed is hyped beyond what will actually happen in my honest opinion.
Truth be told, I'd rather have you in a different defense contractor in the short term, but LMT's performance is truly remarkable and I still have a BUY on these perennial EPS outperformers. They were up 32.8% during the last 2001 recession, and are poised to outperform the market again in 2008. What's more, their 10-year annualized return is up at 7.3%. What I am trying to say is, Lockheed Martin is historically one of the top performers in a recession, and this go-round shouldn't be any different.
General Dynamics (NYSE: GD)
General Dynamics is poised to be the largest holding in the Nittany Lion Fund, LLC., and I am generally stoked about their prospects for the year. GD has a leading market position in the areas essential to the U.S. military and has a strong track record of generating capital under every market condition imaginable.
The new Gulfstream G650 aircraft, from the leading unit of GD Aerospace, has really improved on fuel efficiency and speed (among other things) and I feel like the long-awaited release could really benefit sales. This is pretty much the world to GD, and offers a huge amount of visibility with low risk. Other than this, I continue to recommend General Dynamics because of their "no surprises" business model that continues to perform well, offering beatable 2008 EPS guidance and great long term prospects, that guarantees a safe investment.
Raytheon (NYSE: RTN)
RTN is really a conviction buy in the fact that they have an increasing foreign exposure, above average cash flow and a recession-proof portfolio. A lot of investors have Raytheon as the #1 defense company stock for 2008, and I really can't argue with them. I do not like the fact that this company is overly tied to the Bush Administration, and would be effected slightly by a reduced US presence in Iraq or a more pro-China President (because of arms supplies to Taiwan). However, you need to consider that the defense budget is relatively stable.
Raytheon is set to benefit from some big contracts in homeland and border security, such as a %2B billion Saudi middle east border contract and the ability to capitalize on cyber security after acquiring Oakley. Strong foreign orders and redeployment of cash should drive Raytheon into a profitable 2008/2009, and I stand by the hype.
Northrop-Grumman (NYSE: NOC)
All the buzz over Northrop-Grumman has been the contract win over Boeing to supply a new tanker worth a potential billion. Despite Boeing's dispute, NOC will more than likely come out with the win on this one. Regardless, I feel that the bigger development is Northrop's "Guardian System," a missile-jamming "pod" that can be attached to aircraft to prevent them from getting shot down in hostile flight areas. Before this system was released on March 26th, it was widely expected to favor Raytheon and BAE Systems... I think this can be a huge driver for NOC that has really gone unnoticed in the market.
Northrop is a steady performer at an attractive price. With a PEG at 0.88 and a Beta at just 0.38, they seem to be ripe for investment. Not only are the valued well, but they have that low debt that we love (debt/equity is just 0.23). The numbers are good, they are getting contracts nobody thought they would get, and they carry low risk in a poor market environment. NOC is good.
The power behind defense in a down market is the ability to lock in contracts, backed by a rising national defense budget, for the long term. The big five all have their advantages, and I would expect most of them to capitalize regardless of what twists and turns are in store for the rest of the market. Sometimes, the best offense is a good defense!
