Green Tea Compounds Prevent Memory Loss From Lack of Oxygen

People with sleep apnea, a disorder that affects more than 12 million people in the United States, literally stop breathing repeatedly during their sleep, sometimes for a minute or longer. With the most serious form, obstructive sleep apnea (OSA), this can happen hundreds of times during a single night and deprive the brain of oxygen.

The result? Possible brain damage causing memory problems. In fact, people with OSA are known to have increased markers of oxidative stress and exhibit changes in their brain tissue in areas involved in learning and memory.

But natural substances in green tea appear to stave off these OSA-caused cognitive deficits according to new research published in the second issue for May of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Scientists studied the effects of green tea polyphenols (GTP, for short) on rats who were intermittently deprived of oxygen in order to simulate the lack of oxygen, known as hypoxia, that humans with OSA experience. Chronic hypoxia in rats is known to produce similar neurological deficit patterns seen in humans with sleep apnea.

Previous research has shown that GTPs may reduce the risk of a variety of different diseases, most likely because they possess anti-oxidant properties and act as free radical scavengers. "OSA has been increasingly recognized as a serious and frequent health condition with potential long-term morbidities that include learning and psychological disabilities," David Gozal, M.D., professor and director of Kosair Children's Hospital Research Institute at the University of Louisville, said in a prepared release for the press. "A growing body of evidence suggests that the adverse neurobehavioral consequences imposed by hypoxia stem, at least in part, from oxidative stress and inflammatory signaling cascades."

Dr. Gozal and his colleagues divided 106 male rats into two groups that underwent intermittent oxygen deprivation during the 12-hour "night" cycle for 2 weeks. One group received drinking water containing GTPs while the other group received plain drinking water.

Then the animals were tested for markers of inflammation and oxidative stress and their spatial learning and memory was measured by putting them through in a water "maze". To get out of the water, the rats had to memorize the location of a hidden platform.

The rats who received the green tea-treated water clearly had the better memories and performed significantly better in the water maze than the rats that drank plain water. So the researchers concluded GTPs "may represent a potential interventional strategy for patients" with sleep-disordered breathing, according to Dr. Gozal, who headed the research team.

Using green tea instead of drugs prevents brain deficits due to hypoxia and could be an important aid to preserving the memories of millions of people suffering from sleep apnea. What's more, green tea may well contain substances that offer hope for a variety of other brain-injuring diseases. "Recent studies have demonstrated the neuroprotective activity of GTP in animal models of neurodegenerative conditions such as Parkinson's and Alzheimer's disease," Dr. Gozal wrote.

Eight Natural Ways To Prevent Cold and Flu

With the cold weather coming upon us in the northern hemisphere everyone naturally becomes concerned about catching a cold or flu and staying healthy. Of course mainstream medicine and news talks a lot about getting flu shots as if that's the only possible thing that you can do to prevent the flu. That may be the case in their view of health and healing, but this is not so in the case of Chinese and other alternative medical systems.

The Chinese in particular have a deep understanding of what truly happens in the body when you catch a cold or flu. This does not have to do with viruses and bacteria, but rather with various atmospheric energies that are prevalent during each of the seasons that cause various illnesses due to the effects of those seasonal energies. The young and elderly are usually particularly susceptible to these seasonal changes and need to take extra precautions to guard against getting sick at these times.

The reason that a seasonal change, particularly from the warm to cold weather affects us all is because the body can often be slow to adjust to the changes in prevalent atmospheric energies at these times. In the summer warm yang energies are prevalent which generally strain the kidneys. The kidneys are a water organ meaning that they control water functions of the body. This includes keeping the body cool which is why drinking enough fluids in warm weather is so critical. In the fall the lungs are affected as the dryer air usually causes an increase in coughs and sometimes allows us to catch a cold.

In the winter the heart is stressed because the heart being the fire organ has to work harder to keep us warmer. If the heart is not able to adjust sufficiently then external cold energies that are strongest in the winter time, then cold (yin) energies can penetrate the bodies external shielding and cause us to catch a cold or flu. This is what people commonly call "catching a chill". When this happens it's often a sign that external cold energies have gotten into the body.

These terms are not just outdated colorful language but very real descriptions of very real energies that exist in nature. This is because the Chinese know that one of the major energy laws that affect all health issues in the body has to do with the balance of fire and water energies within the body. This is even true within each internal organ. When someone gets a cold or flu it really means that external cold energies have penetrated the body and taken hold thus causing the common symptoms of a cold or flu.

The skin and lungs are the most common places that these cold energies pass through our bodies and enter our systems. In Chinese medicine the skin and lungs are linked together which is one reason that people who smoke often have dry skin. Because smoking weakens and dries out the lung tissue itself and thus weakens other organs directly linked to the lungs such as the skin. The lungs and skin are paired organ system in Chinese medicine. Many have heard that if someone's skin is completely covered with paint for example, they can actually suffocate even though they can breathe through their lungs. This is more proof of the accuracy of this and many other linked organ pairs in Chinese medicine.

In the body there are four different main types of Chi or energy that govern the four main systemic functions of the body. One of these four energies is called "Wey Chi" or "guardian Chi" Wey chi is energy that sits on the surface of the skin and radiates out about a centimeter or so from surface of your skin. It is the responsibility of this energy field to protect the body from external cold and wind energies. Anything that causes you to become too fatigued or tired such as lack of sleep, stress and poor nutrition or simply being out in the cold too long without adequate protection will weaken your guardian chi field and increase your chance of catching cold, flu or other similar illnesses.

How to Strengthen Your Energy Shield

So what can you do to increase your energy shield and help protect yourself from cold and flu this and every season? Fortunately there are many simple and easy methods available to help boost your guardian energy.

You can simply add some more physical exercising to your regimen. You can do everything from push ups with static holding at the end of each push up set which will help heat up the body and thus lead more energy to the skin and beyond. Just about any kind of physical exercise with light to moderate resistance will help in this regard. This is particularly true when doing exercises that cause you to hold either your arms with our without weights in various postures for a minute or more. Working the mid section via crunches and sit ups with holding at the end of each set will strengthen the core organs so vital to immunity. This also applies to the legs which have many major organ/energy meridians that travel down them. These include the kidneys, liver and spleen in particular.

One simple exercise to do is to stand with your feet shoulder width apart and toes pointing foreword. Keep the hips pulled back slightly. Raise the arms up to shoulder height with the fingers pointing towards each other and the palms facing your chest making a sort of basketball hoop with your arms. Bend the knees enough so that when you look down you can't see your feet with your back straight and try holding this simple posture for several minutes each day. This is a classic exercise to build up yang energy and strengthen guardian chi. It can even build up a good amount of strength and endurance when done regularly.

You can also make sure that you're eating enough warming yang foods this winter such as organic meats like turkey, chicken, fish and even small amounts of red meat and butter which are effective at building yang energies. The long burning calories from these animal sources are necessary in colder climates to help the heart keep the body warm. Since the heart prefers natural fats over all other dietary sources for its fuel, these foods will help increase warming (yang) energy production and ease the strain on the heart at the same time.

There are herbs and herbal teas that you can drink to increase internal fire energies in the right way too. Some of these include warming herbs such as ginger, ginseng, cayenne and horny goat weed. Drinking teas made with these herbs can be a good measure to help prevent or treat a cold or flu.

Some other simple methods to help fight cold or flu include getting in a warm to very warm bathtub and letting the warm yang energies of the water penetrate the skin and boost the overall warming energy of the body. You can do this for as long as you like up to forty minutes to an hour or more. This is particularly helpful in strengthening the kidneys and lungs as they are main organs involved in the immune system and are often affected in illnesses of external cold penetration such as cold and flu. The body will absorb the warming energy from the water and this balances the internal cold in the body thus resulting in symptom relief and accelerated healing.

Another technique along these same lines is to place just your hands in warm to very warm water for five minutes or more. Try to make it as warm as you can comfortably stand without burning yourself. The many energy meridians that terminate in the hands will absorb the warmth of the water via these energy channels and the nerves and transmit that warmth back to their respective organs. This technique is good to give a quick boost to the immune system when taking a long bath is not an option such as at work or at a friend house. Even just running the hands under a warm faucet can have similar immune boosting effects too.

Practicing an exercise called the "thymus tap" is also beneficial. The thymus gland is located above the breast bone in the center of the upper chest. Using the flats of the knuckles to tap this gland with light to moderate pressure 200-300 times several times a day will boost immune function significantly. The thymus gland is one of the master glands of immunity in the body and this helps to stimulate and increase the production of T-cells that help fight off germs and infections which often result from a weakened immune system. This is also an excellent exercise to add to your regular health regimen for added immunity.

Lastly you can practice this simple breathing technique as a daily preventative or during a bout of cold or flu to help increase warming yang energy in the body. Take a long deep breath and then upon exhalation lightly tense up all the muscles of your body. Keep the muscles tensed for the duration of your exhalation which should last about five seconds. Take one or two slow deep cleansing breaths, and then repeat. You can do this exercise between five and ten times in a row. Rest for a few minutes and take several slow deep breaths to cleanse the body and calm the heart between sets and begin again if needed. You should feel warmer after even a few breaths and you may notice some mild to moderate symptom relief too.

If you have any existing heart conditions then I would skip this exercise and consult with your doctor first. That's because this can build up significant amounts of yang energy and can cause increase in your heart rate. This is a martial art technique that was discovered centuries ago in the north of China. They found out that it was also very effective at keeping warm during the cold winter months and also that it greatly helps during an invasion of cold (yin) energy characterized by cold and flu symptoms.

If you practice these and other natural techniques which include simply dressing for the season, getting plenty of rest which also boosts overall guardian energies, proper supplementation via herbs, vitamin and mineral supplements and adjusting of the diet to keep you warm, you'll greatly reduce or even eliminate your changes of catching a cold or flu this season. You'll also increase your overall resistance to many other diseases via the combined immune boosting effects of all of these techniques.

Natural Remedies for Laryingitis

Laryngitis leaves a person speechless. At best, the person speaks in a raspy tone or in a whisper. Severe cases lead to a complete loss of the voice. It is inconvenient, especially if your occupation involves a great deal of vocal communication. Acute laryngitis lasts just a few days, but chronic cases can last weeks or even longer. Sometimes it is painful.

The larynx is located in the throat. It is commonly known as vocal chords or vocal folds. It becomes inflamed (the 'itis' part of laryngitis) for a number of reasons. A virus, as in a cold, is the most common cause. Bacteria and fungal infections can also cause hoarseness. The coughing which comes with respiratory illness may lead to laryngitis. Over use or abuse of the vocal chords through excessive shouting or incorrect singing habits stress the voice, causing inflammation.

Smokers may find themselves with a case of laryngitis. A heavy bout of alcohol intake irritates the throat as well. The throat may erode due to acid reflux. Occasionally, the vocal chords may be disturbed by the presence of a tumor, leading to loss of vocal power.

We cannot claim to cure or treat laryngitis. Natural healing does not necessarily offer specialized recommendations. Instead, illness or disease is seen as an indication that the body is over loaded with issues which cause stress. Issues range from improper care for your body to toxic pollutants.

In our hectic lives, we often neglect the proper care and feeding of our bodies. Insufficient rest, junk food (and drinks), and exposure to environmental toxins take their toll.

At the first sign of a sickness, one needs to realize that the body has been under more stress than it can handle. Too often, we want to take a cup of tea or some pills and continue doing what we have been doing all along. Think again.

Many natural healers recommend beginning intervention for particular ailments with the simplest remedies.

So, let us begin with a common recommendation: get rest and drink plenty of fluids.

Sleep is underrated as a healing modality. True, many ills need a bit more than extra sleep for their resolution, but resting in bed (or on the sofa during the daytime) allows the body to pour its energy more effectively into the immune system.

In addition, while you sleep, in the dark of night, melatonin is produced. Melatonin is important in regulating the body's daily (circadian) rhythm. It is a powerful antioxidant, which can cross cell membranes and the blood brain barrier. Even the products of melatonin's attack on free radicals have antioxidant activity. Longevity is one of the side effects of melatonin's action in the body as it seems to generate a powerful response from the immune system. It may assist in fighting viral and bacterial infections, including those which may be implicated in laryngitis.

So, get plenty of rest, especially in a dark room at night. If you need to get up, do not turn on a light. And when you wake up, be sure to drink plenty of water.

Water is essential to life. The body is at least seventy percent water. The body counts on blood and lymph fluids as transportation systems. They carry nutrients and immune system components to where they are needed and cart off waste products. Too many people stumble through their day to day lives depriving their bodies of necessary fluids or consuming substances which decrease the available fluids. So, it is essential that one increase fluid intake during times of stress.

Certainly, the first choice of fluids is good quality water. Much has been written about pure water so we need not cover that topic here. Suffice to say that if you drink contaminated water, it will be more difficult for the body to focus on cleaning up the vocal chords.

Eliminate dairy products. While that dish of ice cream may sound appealing when your throat is hot and sore, its effect will be extremely short lived. Milk products tend to increase mucus production in the body, which tends to muck things up. In the end, mucus accumulation makes it more difficult for the immune system to send in the troops.

Other helpful liquids are available which can assist in clearing the mess which has led to the laryngitis.

Honey has been shown to be as effective as patent cough syrup. It is astringent, clearing away inflammation and some of its causes. Raw honey has enough sugar in it to give that little boost of energy and many of the enzymes to help the body effectively use that sugar. The little bit of nutrition in honey also helps in healing.

Add freshly squeezed lemon juice (or raw apple cider vinegar) in equal parts with the honey. This can provide vitamin C and some of the electrolytes which help to bring the acid/alkaline balance back to unhealthy tissues.

Squeeze the juice from half a lemon, mix it with a tablespoon or two of honey. Add this mixture to a cup of water. It does not matter if the water is warm or cool. Now, stir in one tenth teaspoon of cayenne pepper. Yes, you read that right – cayenne pepper. The cayenne helps to break up mucus accumulation in and around the inflamed tissue.

A similar recipe, substituting grade B maple syrup for the honey constitutes the Master Cleanse. During the cleanse, drink ten to twelve cups of this lemonade throughout the day. Generally the Master Cleanse is presented as a form of fasting. You probably don't feel much like eating when your throat is so sore and swollen.

If the concept of hot pepper intimidates you, try mixing honey and lemon in sage tea. Steep a tablespoon of dried sage leaves in three cups of boiling water. Do not boil the sage leaves, just pour the boiling water over the leaves and cover for fifteen minutes. Strain and add lemon and honey as above.

Another remedy recommended by the old herbalists is garlic syrup. Peel and chop the cloves of several garlic heads and place them in a jar. Cover with equal parts apple cider vinegar and distilled water. Shake well and allow to sit for four hours. Strain and add an equal amount of honey. Shake together. Cap. Store in the refrigerator. Take a teaspoon to a tablespoon every six to eight hours.

We cannot leave this subject without mentioning Grandma's favorite remedy for what ails you: Chicken soup. Any soup, for that matter, which is made with lots of herbs and vegetables provides easily digestible nutrition. Our fore-mothers knew, perhaps intuitively, that herbs are for much more that taste. Many of them have antibiotic properties and can be a strong ally in repairing the damage we do to our bodies from day to day.

When you have laryngitis, realize that your body is telling you that you have not given it the care it deserves. Slow down, and get extra rest. You will find that you don't have much appetite, so don't be afraid to cut back on your food intake (especially those junk foods that we are all so fond of). Drink plenty of fluids. Honey, lemon, sage, and garlic are primary tools for getting back in communication with your world.
