Green Tea & Sleep Apnea

by Elena Popec 22. June 2010 07:41

Sleep apnea is a form of sleep disorder that impedes the breathing process during sleep, and if you have it, you know it’s absolutely no fun. It can cause your breathing to pause or even to stop during sleep. It can be dangerous, and lead to a variety of other risky health problems.

Problems associated with sleep apnea

It may lead to problems with cognitive abilities such as learning and memory skills, as well as impede other cognitive abilities. Sleep apnea can also mean that you don’t get as much sleep as you should, and the sleep you do get is not restful and does not help restore and refresh your body.

Getting a good night’s sleep is vital
   
A good night’s sleep is actually extremely important for your body. It restores the body to prepare it for a new day, and refreshes the cells. Not getting a good night’s sleep is a tremendous problem, as sleep serves an incredibly important part of maintaining a healthy lifestyle. Lack of good, restful sleep can interfere with your daily functioning and impede on your life.

Other effects of sleep apnea
   
Sleep apnea, otherwise known as obstructive sleep apnea, is a condition that deprives your body of oxygen while you are asleep. A person who suffers from this condition may experience pauses in breathing while asleep, and their breathing may even stop. This can lead to a drop in oxygen levels, and if oxygen doesn’t get everywhere that it’s supposed to, this can have a negative impact on organs in the body. Breathing is tremendously important, and during sleep it is especially dangerous not to get enough oxygen into your body.
   
This condition also increases the risk for other health problems such as heart attacks, high blood pressure, and strokes. It’s definitely a condition that is necessary to prevent, and green tea may be an aid in sleep improvement.

Green tea can help
   
Green tea is packed with antioxidants which may help improve memory and other cognitive functions. It also contains polyphenols which counteract oxidative stress that occurs in the brain. Damage to cells caused by free radicals, a type of harmful molecule, causes oxidative stress. This in turn causes other types of complications and illnesses. It can also affect memory and learning skills.
   
Fortunately, the polyphenols that occur in green tea work to counteract oxidative stress. They are found in abundance in loose leaf green tea and also in various fruits and vegetables. Loose leaf tea is also the best way to get all the nutrients from the tea. It is more natural, healthy, and hasn’t been processed to the point of beating out all the nutritional value. Loose leaf green tea is also much more flavorful, and far superior.
   
Tea bags have pounded and processed the leaves, leaving you with a bag full of tea dust that is, while not entirely void of, lacking in many nutrients found in loose leaf tea. Organic tea is even better for you, as tea that is not organic may have traces of harmful chemicals. When you drink tea, you want to be drinking the tea that is going to actually give you the health benefits that you need to improve your sleep.

Organic Tea: A Better Choice by Far

by Elena Popec 7. June 2010 10:43

Organic tea is a healthy, delicious choice and has been becoming more and more popular in recent years. The demand for organic products has led to these types of teas being available from mainstream tea companies and in most supermarket chains. It’s easier than ever to buy organic tea.

Why is Buying Organic Tea Important?
   
Avoiding toxic chemicals is one of the main benefits of buying organic tea, and of course there is also the benefit of helping to protect the environment.

Toxic Chemicals:
   
Non-organic teas may have traces of harmful, toxic chemicals due to the use of pesticides in the production. Much of the tea available in stores comes from China and India, where the environmental regulations are not as stringent as those in the United States or countries in Europe. The toxic chemicals in pesticides can be dangerous to ingest and be a risk to the health of people drinking the tea. There are many benefits to drinking tea, such as properties that may help prevent cancer, but this is outweighed by the toxic effects of the chemicals used in the production. Some of these chemicals are known to have carcinogenic effects and toxins.
   
The consumption of teas that have used these chemicals in their production can cause health problems for people who drink it. It’s dangerous as well for people who live near the area of production as the areas may have become contaminated by the toxins. By buying tea that has been produced by such methods contributes to the environmental contamination and to the health problems the people in the area suffer from.

Nutrient Pollution from Fertilizer:
   
Beyond the toxins that are in the pesticides used for production, there is damage to the environment itself. The overuse of fertilizer can destroy the environment. Tea needs fertilizer to grow because as the tea leaves are harvested the organic matter is taken away. Overusing fertilizers can acidify soils and add nitrogen to runoff. This is incredibly destructive, as these damages entire ecosystems in rivers and streams and even in bays near the region or area that grows the tea. The effects of this are devastating and can destroy or damage the fishing industry as well.
   
Using organic fertilizer helps, but doesn’t completely eradicate this problem.

What does Organic Certification Mean?

   
Organic certification has certain requirements that the tea is produced without the use of synthetic chemicals. This generally includes pesticides, herbicides, and fertilizers. The organic cortication does vary depending on the organization that determines the certification, or on the product that is being certified. The certification also prohibits the use of genetically modified organisms. It also requires a certain number of years that the land has had to have been maintained free of synthetic chemicals. The organic certification also requires records to be kept to make certain that organic materials are kept separate from non-organic materials.
   
In the United States, the USDA is the organization that determines organic certification. In other countries there are a number of other agencies that certify products as organic.

Organic Agriculture is not Perfect:
   
Of course organic agriculture is not the end-all solution to all environmental problems, but it is a step in a positive direction. There are flaws with the process of course. Some products are falsely marked as organic by some companies so that they can sell them at a higher price. It’s important to check the certification of the teas, to make certain that they do have the proper organic certification. But even when the product has been certified, organic agriculture itself is not without flaws. It can still have some damaging impacts on the environment. And the certification process doesn’t address other problems. There is a need for fair wages for workers, which is not addressed by the organic certification.

Is Organic Tea More Expensive?
   
It depends. Sometimes it is, but the prices of teas vary. Many organic tea prices are comparable to non-organic tea prices; they may be about the same or even a little less expensive. Organic tea is healthier and better for the environment and is becoming more readily available. It seems like common sense to buy organic. As buying organic becomes more and more common, and then the focus can be addressed to more environmental concerns and public issues. We can begin restoring the earth’s ecosystems, keep toxic chemicals out of our environment, and help people by addressing the needs for fair wages for workers.

Tea: The Essence Of The Fragrance

by Steven Popec 29. April 2010 20:37

The fragrance of tea depends on the essential oils and tar substances that are contained in plants. Essential oils are complex mixture of substances that belong to the most diverse class of compounds which are soluble in organic solvents and possessing the ability to escape from water vapor. Overall the total content of essential oil is minimal; it is determined by only hundredths of a percent. For example, aromatic black tea contains about 0.02% of oil. Pure essential oil of fresh tea leaf is a green color with a strong fragrance of fresh greens. In the technological processing of tea leaf occurs the formation of a new aromatic substances that contribute to the specific flavor of the finished product. Thus, the composition of essential oil of green plants is different from the finished black tea. The substances that make up the oils can be divided into 4 main classes of compounds: acids, carbonyl compounds, alcohols and phenols. These volatile compounds found in tea are trace amounts - 0.01% of dry matter, but their role in the establishment of the tea flavor is tremendous. 
 
Some parts of the plant contain different amounts of volatile compounds, which, in turn, differ in their compositions. The maximum concentration of essential oil found in the tender stems and leaves. The top leaf with the growing bud and two next leaves are equivalent to the content of essential oil. Further down the stem, as general coarsening occurs, oil content decreases. Which explains why the top three leaves are the most vaulable for high quality tea. 
 
In the formation of the aroma of tea, the main role is played by aromatic aldehydes (Organic compound that has OH-group in its structure. They are used in organic synthesis as fragrances). In the composition of essential tea oils are vanilla, lavender, cinnamon aldehydes, etc. During the processing of tea leaves into black tea, the various fractions of volatile compounds undergo significant changes. The total content of these compounds increases most radically in the early stages of rolling. In the process of withering the relative content of components with higher boiling point reduces and low-boiling point, on the contrary, increases. 
 
Along with essential oils important role in creating a tea aroma played by various resinous substances - carriers of flavor. They are in a close chemical relation with essential oils and are a complex mixture of different classes of organic compounds. 
 
The content of tarry substances in tea leaves ranges on average from 3% to 6%. These substances are separated by several fractions, the most valuable of which is a neutral faction. It has a pleasant sweet floral aroma. In the process of technological treatment , the amount of this fraction in tea leaves increases by 40%. 
 
During the processing of tea leaves, the content of resinous substances decreases, indicating the result of oxidation. I.e. ratio: fresh leaves – 3.48%, withered leaves – 3.27%, after two hours of curling – 2.92%, semi-finished product – 2.35%. 
 
Through fragrance of tea, all the deficiencies that have arisen as a result of violations of technological regimens or improper storage of products, can easily be found. Disadvantages may include: acidity, mustiness, smell of the green, smoke and other uncharacteristic for tea scents. Most difficult to improve defect is acidity, which results in a violation of the fermentation process. Since in the processing of tea leaves, especially during the fermentation, occurs a reduction of Tannin. Therefore, the tea produced in violation of this process turns out with a bitter flavor and pale color of infusion. The cause of the smell of greenery is an infringement of withering, rolling, and fermentation. Such a tea has a mild flavor that the brew is a greenish color in the cup with a greenish ring on the surface and instead of the characteristic astringent taste; this product has a bitter taste. If there is excessive moisture in semi-finished product (more than 7.5%) tea is aging much faster. For extended storage. it gets the smell of dampness and can come in unsuitable conditions for consumption. 
 
In addition, it is worth noting that different varieties of tea, as well as different ways of brewing, have an imprint on the final quality of the drink
