How To Prevent Allergy
An effective allergy treatment can only begin after the type and cause of the allergy has been identified. An allergy, when it develops, usually renders the immune system ineffective and so the right allergy treatment must therefore help the immune system become strong enough to fight the allergy. A solution is to ensure removing allergens in the home so that the chances of developing pet allergy are greatly reduced.
Frequently, an allergy treatment will require that the patient is injected with something that includes anti-bodies that in turn will help to strengthen the immune system and so destroy the allergens. However, appropriate allergy treatment for a person really depends on quite a few factors which need to be discussed by you with your doctor. There is however no denying the fact that antihistamines are the most commonly used in allergy treatments and in particular you may be prescribed Claritin which is very effective in treating symptoms of allergies.
Allergies cause a wide range of symptoms. Allergies can cause a runny nose, sneezing, itching, rash, swelling or asthma. Fatigue is also common in allergy season. Older antihistamines that did not cause drowsiness, ‘help to fatigue, but now the new antihistamines typically don’t cause drowsiness. Risk factors for allergy can be classified into two broad categories is hosting the first and second environmental factors. Host factors include heredity, sex, race and age, heredity is by far the largest. There are recent increases in the incidence of allergic disorders, however, which can not be explained solely by genetic factors.
Five Allergy Treatment and Prevention Tips
1. Vacuum your carpets on a daily basis and also damp out dust at least once in a week.
2. Avoid all feather bedding.
3. Keep your fridge spotlessly clean and remove any signs of mold.
4. Animal fur is a potential allergen. It’s best to keep pets out of the kid’s room.
5. Antihistamines help reduce the sneezing, runny nose and itchiness of allergies.
Without any doubt prevention of the possibility of inhaling allergens is the best allergy treatment because if you don’t breathe allergens you won’t develop an allergy. Some people suffer from pet allergies and for them there are many simple yet effective pet allergy treatments available that will prevent a fresh outbreak of pet allergy and in fact, many of these treatments are natural and therefore safe to use.
You will also need to vacuum your carpets on a daily basis and also damp out dust at least once in a week. Other than this, you need to ensure washing your hands with a good soap each time you have played with or touched your pet. Other simple pet allergy treatments include installing air purifier in the home which will remove pet dander from the air and to have wooden floors instead of carpeting the floors which will only trap the allergens and that will mean increasing the risk of pet allergies.

Ionic Air Purifier Technologies - Who Is Telling The Truth?
Introduction
Ionic air purifiers hold the promise of clean air, purified of all known harmful contaminants that threaten our health. Naked eyes cannot see these harmful contaminants. The weapons against such are very likely to be invisible to our eyes as well. I am drawn to this intuitive logic. But these days, finding a simple and quick solution is rare. Googling the subject unearths a ton of controversy. Obviously, I must resist the urge to go by intuition and grab the first ionic air purifier that I lay hands on. Product safety must take precedence over effectiveness in choosing an ionic air purifier.
The recent China melamine saga that killed infants also serves as a reminder to us that in buying into any technology or any product, all claims by manufacturers and distributors must be examined to the fullest extent that our resources permit. This is even more critical when the key reactive agent is unseen to the human eye. Invisible ions of ionic air purifiers fall squarely in this realm.
In this article, I am laying out the roadmap as I look into the existing ionic air purifier technologies in the global marketplace. My back-to-basics approach is an attempt, as a layperson, to understand the science behind the technology. The current key trend appears to be the creation of a potent invisible defence shield against airborne molecular contaminants that threaten our well-being. The prime threat being closely monitored by scientists all over the world is the avian flu virus.
Types of Ionic Air Purifier Technologies
Broadly speaking, air purification technologies can be deployed in either passive or active modes. In passive mode, impure air is drawn into the air purifier for reactive agents to work on before re-emerging as cleaned air into the environment. Active mode depicts the proactive process of bringing the purifying reactive agents into the surrounding impure air. Interestingly, marketeers betray their lack of confidence in their own ionic air purifier technologies by combining both passive and active modes.
In the global market today, ionic air purifier technologies include the following categories:
(A) Ion generator - positive and negative ions
(B) Ion generator - negative ions only
(C) Photocatalytic Oxidation (POC)
(D) Electrostatic filter
(E) Combos
Ion Generator - Positive and Negative Ions
This combination of positive and negative ions appears to show the most promise for the future of ionic air purifier technology. Developed by Japanese ingenuity, Sharp Corporation to be exact, they are known as plasmacluster ions.
Positive and negative plasmacluster ions actively surround harmful bacteria and viruses in a deadly embrace. When clumping occurs, hydroxyl is produced. Hydroxyl, also known as nature’s detergent, is a powerful reactive species that destroys airborne particulates by plucking out hydrogen molecules from their organic structure. This chemical reaction generates harmless by-products, the main of which is water.
A differential ion generator is used in this technology, comprising a positive and a negative ion generator which can be powered in alternate cycles to control the type of ions generated.
Advocates of the positive and negative ions combination claim that a balance of both these ion types is to be found in places like waterfalls and pristine forests, i.e. this is the actual state in nature. Diametrically, believers of the negative ions technology take the view that negative ions dominate the space in natural habitats and that positive ions are actually harmful. In this regard, I have yet to find independent scientific studies as evidence for the contradictory claims of both camps.
Ion Generator - Negative Ions
The traditional ionic air purifier produces only negative ions. This method seems to dominate market share in the industry but is coming under serious threat from Sharp’s plasmacluster positive and negative ions technology.
It is claimed that nearly all harmful airborne particulates like dust, smoke and bacteria etc have a positive charge. Negative ions from the air purifier attach themselves to these particulates until they get weighed down and fall to the ground. Regular vacuuming removes these impurities from our environment. Weighing down the particulates does nothing to destory them, according to critics, and merely walking on them causes the air to be polluted again.
In addition, there appears to be several methods of producing the negative ions. This is important because different methods produce different by-products, some of which may be harmful. These methods include:
(1) Water method - this employs what is known as the waterfall or Lenard Effect. Onto a metal plate that is electrically-charged, water droplets are splashed. This simple action results in the splitting of water droplets, causing the production of large numbers of negative ions. Proponents of the water method believe it to be free of harmful by-products.
(2) Electron radiation method - this is based on a single negative discharge electrode needle. The simple application of a high voltage pulse to the electrode results in millions of negatively-charged electrons being produced. An advantage of this method is that no ozone is produced. This is attributed to a “smaller” energy pulse being applied.
(3) Corona discharge method - this is based on a dual electrode model, a sharp metal electrode and a flat electrode. A very high voltage is applied between the two electrodes. This causes the movement of electrons between the electrodes thereby ionising the air in between them. A criticism of this method is the production of harmful by-products like ozone and nitride oxide.
Photocatalytic Oxidation (POC)
This technology is commonly applied in a passive mode. It is also based on the powerful reactive agent hydroxyl which purifies impure air that is pulled through the air purifier.
Germicidal ultraviolet (UV) light is commonly shone on a catalyst (usually titanium oxide) to produce hydroxyl, oxygen and peroxide, all of which are potent oxidising agents that are very effective at destroying the organic structure of micro-organisms and gaseous volatile organic compounds.
Complete and comprehensive action is the pillar of POC technology. Proponents of this technology claim that POC inactivates ALL categories of indoor pollution, including:
(1) airborne particulates i.e. dust, pet dander, plant pollen, sea salts, tobacco smoke, industrial and car pollution, etc
(2) bioaerosols i.e. biological compounds that may be infectious or contagious (e.g. viruses and pathogenic bacteria) or non-infectious (e.g. non-pathogenic bacteria, molds, cell debris)
(3) volatile organic compounds (VOCs) i.e. gaseous chemicals or odours - benzene, styrene, toluene, chloroform, hexane, ethanol, formaldehyde, ethylene, etc, all common emissions from everyday products of our modern home.
POC technology has been criticised for relying on hydroxyl which are believed to attack with equal tenacity the organic structures that make up molecular contaminants and our lung tissue, nose membranes and eye cornea.
Electrostatic Filter
This technology appears to have originated in heavy industries which produced abundant pollutants. Typically, an electrostatic filter is made of a porous dielectric material that is positioned between two electrodes. Dielectric materials do not conduct electricity while metallic electrodes are excellent conductors that transmit and receive electricity.
Contaminated air is drawn into the electrostatic puriifer and made to pass over the dielectric material which acts like a sieve. The electrostatic field created between the electrodes causes airborne particulates i.e.dust, smoke contaminants, etc, to stick to the dielectric surface. From the other end of the purifier, purified air emerges.
Very often, an ion source is inserted before the electrostatic filter to charge the airborne particulates. These impurities, so charged, stick more effectively to the dielectric material.
Critics of this technology point to the production of harmful ozone in the ionisation process.
Combo Ionic Air Purifiers
To cater to the various adherents and critics of the diverse technologies, combos incorporate all or some of the above types of technologies. Combos may include:
(1) adsorptive materials such as activated carbon or oxygenated charcoal (known for its extremely porous large surface area) are added to POC technology to enhance the removal of VOCs;
(2) oxidizing catalysts like titanium oxide are coated on various components of all types of air purifiers to enhance VOC elimination;
(3) reducing catalysts such as manganese dioxide are coated near the exit outlets of many air purifiers to reduce reactive species like ozone and nitric oxide which may be harmful;
(4) generating ions by differing methods such as using microwave, UV light, radio frequency waves, and direct current;
(5) tweaking the specifications of any ionic air purifier technology so as to attain the well-known HEPA status without actually using HEPA filters.
Obviously, the process of selecting the most efficient and effective ionic air purifier involves analysing a deluge of information. I have barely skimmed the surface of the safety issues of each technology. I have also not examined in detail the claims of each technology. So before you put your money down for any air purifier in your homes, offices, schools, etc, check back here for updates as I continue my quest for the ideal ionic air purifier.

How to become allergy free for life
Relentless allergy attacks can make a person's life miserable. It makes it hard to work and do anything effective once allergy sufferers come in contact with whatever it is that they are allergic to: whether they be dust mites, human and animal hair as well as shedding skin.
To make life easier for allergy sufferers, different kinds of medications, allergy treatments and control products have become available in the market. They come in many forms and have become more user friendly than ever before. Many may have worked but they could be really expensive, while some can be so unreliable.
Won't life be more easy if we can be allergy free for life? Read this AllergyFreeForLife Review. You have to admit, these allergy control products, treatments and medications only treat and handle allergy symptoms and not the root cause of the problem. You allergy will only keep on coming back and attack each time you come across something to trigger it. Read this Allergy Free For Life Review and see how you can get rid of your allergies once and for all.
Some 54% of people in the US are affected by at least one allergen. People want better products and there have been many created and invented to help fight seasonal allergies. Air purifiers help prevent allergy attacks by getting rid of the harmful allergens in the first place.
Many people have suffered for many years without even knowing that the bed they slept in was the primary cause of their allergy. Now there are allergy resistant bedcovers, pillow cases. Allergy resistant fabrics can also be utilized entirely in one’s home to provide relief to allergy sufferers.
For those chemically sensitive people, life can be a total misery. There are allergy resistant paints and chemicals that really work. Still these are not the real answers in becoming allergy for life. If have an allergy, no matter what you’re allergic to, there are many products that can make life easier for you. While some can effectively limit your allergy, there are allergy products that can really eliminate your allergy from whatever it is in your immediate environment.

Decongestants to Combat Allergies
The Sinus Infection Cure Review
Another way of curing allergy symptoms is the use of decongestants that helps decrease nasal congestion through the narrowing of the blood vessel and by lessening blood flow into the nasal passage. This method of allergy relief must not be used if a person has known allergies to decongestant and this may cause infuriating side effects among people who posses the following conditions:
* Narrow-angle glaucoma
* Coronary artery disease (refers to the hardening of the arteries)
* Poorly controlled high blood pressure
The use of decongestant is to provide temporary relief only hence it should not be used for more than 5 days. That’s one reasons why it is not one of the best treatments for seasonal allergies. Prolonged use can worsen congestion so you better take responsibility towards your actions. This should also be used with caution when you are also taking herbal drug preparations that are also known to increase blood pressure. Illicit drugs like cocaine must be avoided as well since this is known to also increase blood pressure. To avoid side effects you should look for the best natural treatment for allergies and find natural remedies as an alternative to prescription drugs.
Too much use of this drug can lead problems of nasal passages and it may even worsen allergic symptoms. Furthermore, seek medical advice before use any decongestant for you to understand the right dose that your body can take.
Are decongestants the best nasal allergy treatments?
No, they only provide temporary relief and you should seek a long term solution.Look into allergy cures like The Sinus Infection Cure and Allergy Free For Life.
Keep in mind that medicine dosage is subjective hence you cannot just follow the dosage given to your neighbor who was treated with allergies. Do not take more than the recommended dosage of your allergy decongestant to avoid long term problems.
