Allergies can be easily prevented by taking a few simple precautions. Allergies symptoms can be incredibly difficult to tolerate, and range from everything including a rash to uncontrollable sneezing.
Know what your allergy is. The easiest way to prevent allergy symptoms is to know what you are allergic to in the first place. While some causes of allergies may be obvious; a classic example is hay fever; there are some far more obscure allergies. For example did you know that you can be allergic to birch antigens contained in birch trees and some fruits? In order to find out, you can go to a doctor who will give you an allergy test. Allergy tests work by exposing you to different allergens and seeing if you react to them. It isn't exactly a pleasant process, but it will at least give you some answers.
Once you know the cause of your allergy, avoid it. While this may seem like a very obvious thing to do, you would be amazed at how many people suffer from dog allergies, yet still keep one as a pet. In a similar vein, people who have dairy allergies will often eat large amounts of chocolate, claiming that 'just a little won't hurt.' This is not the case, and having that attitude can be very damaging to your body. If you had a nut allergy you certainly wouldn't eat them! So why treat your allergy to dairy any differently? While your reaction may not be fatal, it will certainly be uncomfortable and bad for your body.
Take care of your surroundings. If you live in a clean and healthy environment it is less likely that there will be a substance to exacerbate your allergy. Particularly if you have a dust allergy, keeping the house clean will stop an excess of irritant building up; it should also stop an excess of dust mites, which are a real irritant, and often build up when bedding has been used for a while.
Taking care of yourself is also a good way to deal with the problem. While a healthy diet won't cure you, it can help to make the body's reaction to foreign substances or allergens milder. Making sure that your body is in the best possible condition will ensure that you get the best out of any help from outside sources such as antihistamines.
Have antihistamines handy. If you find that you can't completely avoid the cause of your allergy, it is always best to have a treatment on hand to deal with the allergy's symptoms. For those people who have more serious allergies, see your doctor. They should be able to advise you on what to carry with you. For example, people who have a nut allergy will often carry EpiPens to deal with their condition as it can be life threatening, so getting fast and effective relief is vital.
