Health Tips and Technics

Eyesight degeneration is something that naturally happens to everyone during the process of aging. Prescription or over-the-counter treatments can help slow or remedy this process and laser eye surgery has been increasing in popularity recently but there are less expensive ways to prevent or even reverse sight loss. One way of doing this is by ensuring that you consume specific vitamins through certain foods and by supplementing your diet with vitamins if necessary.
Refocusing your eyes at regular intervals, wearing sunglasses when in the glare, and refraining from unnecessarily straining your eyes are ways to keep them healthy— but proper nutrition is also key. The different parts of the eye and specifically the retina, the macula, and the lens all require a range of different nutrients to function properly and here are a few of the essential ones.    
The three main vitamins necessary for maintaining good eyesight are vitamins A, C, and E. Vitamin A improves vision during the nighttime and in low-light. A concentrated amount of vitamin A can be found in carrots, spinach, broccoli, sweet potatoes, squash, eggs, cheese, and butter. Next, vitamin C, an antioxidant that aids the prevention of cataracts, can be found in most fruits.
High quantities of vitamin C can be found in oranges and other citrus fruits. Vitamin C supplements have grown increasingly available because vitamin C increases immune system functionality. Then there is vitamin E, another antioxidant that prevents cell damage and aging in the eyes. Asparagus, avocado, milk, eggs, spinach, nuts, vegetable oils, and whole grain foods are all high in vitamin E.
Another substance, known as lutein, is found in many green vegetables and eggs and is important to preventing macular degeneration. Lutein is one of many types of cartenoids that can be found in vegetables, all of which help preserve eye health. Aside from fighting cataract development, lutein also slows macular degeneration in the eye that happens normally through aging. 10% of the population aged 66-74 experience macular degeneration and 30% of people 75-85 years old experience it. Some foods with high levels of lutein are kale, spinach, peas, broccoli, zucchini, and eggs. Zinc is also known to slow and prevent macular degeneration. The seeds of pumpkin, squash, and watermelon all contain zinc. Liver and roast beef are also foods that contain high quantities of zinc.
For retinal health, omega-3 fatty acids found in fish oil play an important role. One particular omega-3 fatty acid known as DHA has been found to improve color and depth perception. These oils can be integrated into any diet either by eating fish or by taking fish oil supplements.
Even if you are at the point where your eyesight may be getting worse due to age, you don’t have to worry too much or opt for expensive laser eye surgery. Glasses or contacts may become necessary, but to slow down the process of eye detriment— in addition to refocusing your eyes often and avoiding straining the eyes— having a diet that supplies you with the proper vitamins and nutrients can make seeing things clearly a little bit less of a hassle.

,Are you often bothered by a runny nose, watery eyes, headaches, fatigue, itchy throat, and similar symptoms? Then you are probably suffering the effects of an allergy.  There are several causes of allergies, ranging from food to insect bites.  Oftentimes allergies can be misdiagnosed as the common cold.  However, when these symptoms persist, it is important to try to identify the allergen, or the cause of the allergic reaction.
No one knows for sure why one person has an allergic reaction to a particular substance, while another person does not.  However, it has been found that children, whose parents have allergic reactions, tend to be predisposed to allergies.  Of interest, is the fact that a child will not necessarily be affected by the same allergen that has an effect on their parent.       
Allergens can enter the body by various methods, they can be breathed in, touched, eaten, or injected.  However they enter, they are viewed by the body as being harmful, and as a result, the immune system produces histamines and other chemicals, to combat the invasion.  These are the early stages of an allergy.  The response will be the same, each time you are exposed to the allergen in the future.
Allergies can be triggered by breathing in certain irritants.  Some of the more common ones are pollen, animal dander, mold, and dust mites.  These airborne allergens are very difficult to battle because they are all around in the atmosphere.  In the case of pollen, these are constantly released into the air by trees, flowers, and grasses, and are especially prevalent during the summer, spring, and fall seasons.
In terms of touch, substances like latex can cause allergic reactions.  Latex is made of rubber, which contains high levels of protein. Latex products include rubber bands, gloves, and balloons.  The allergic reaction is due to the response of the immune system, when an individual comes in contact with the natural rubber latex.  Symptoms of this type of allergy can include runny nose, sneezing, hives, and an itchy throat.
Certain foods can trigger allergies.  Some of the more popular ones are: eggs and milk, peanuts, wheat, soy, shellfish, and tree nuts.  It is the proteins in food that is usually the cause of allergies. These are generally not broken down during cooking, or by digestive enzymes, and as a result, they precipitate allergic reactions in the body.  Common symptoms of food allergy include nausea, vomiting, abdominal pain, and diarrhea.
An allergic reaction to medication can also occur.  One of the drugs that persons tend to be especially allergic to is penicillin, or antibiotics which are penicillin based. Painkillers such as codeine and morphine are also known to cause allergic reactions.  Reactions can range from mild symptoms like rashes, to life threatening symptoms that can affect vital organ systems.
Insect stings can also cause an allergic reaction when the body overreacts to the insect venom.  The insects that commonly cause this response are honeybees, ants, and wasps.  These all have a venom sac on their tail, which they use to inject the venom into a victim.
In rare cases, a serious allergic reaction known as Anaphylactic shock can occur, this can lead to dizziness, unconsciousness, difficulty breathing and sometimes death, and therefore requires immediate treatment. As we have noted, the causes of allergies are various.  However, once identified, every effort should be made to either avoid the allergen, or treat the symptoms of the condition.

• Pathogenic bacteria, causes diseases such as plague, anthrax and tuberculosis
• Protozoa,causing diseases like malaria, toxoplasmosis and sleeping sickness
• Fungi, causes infections like ringworm, candidiasis or toxoplasmosis
• Pathogenic viruses cause diseases like influenza, yellow fever or AIDS, which are basically not living organisms and are not microorganisms

This transmission can happen in multiple ways. Air, physical contact, food, blood transfusion, body fluids or through contaminated objects
