An Ounce of Prevention

The following can be considered preventive measures, and may be very helpful a such, as per the adage that "an ounce of prevention is worth a pound of cure". Still, they do not constitute a treatment, and once your situation gets real bad, they may not cut it by themselves.

1. Moisture, moisture, moisture. Oi, moisture. Dry skin is the enemy of atopics worldwide. Take a daily bath with oils, put moisture-loving creams on, the whole nine yards. Other methods may help (primrose oil AKA Omega 6 is claimed by some to be a good skin-moisture helper).
   
2. Antihistamines. Lots of atopics are reacting to allergens, so do your body some good by helping it deal with the allergic reactions (histamine cells).
   
3. Avoidance. Find out what you're allergic and/or sensitive to (those are two different things, by the way) and avoid it. Minimizing dust for example may be a huge factor for people allergic to dust. Contact with chemical agents can make life worse (hire a cleaning lady if you can afford it). Choose your clothes with care. Etc. I may write more about this someday.
   
4. Climate control. Rapid temperature changes make life difficult. If you live in a cold place, dress warmly and cover up as many areas as you can when stepping outside. Keep a relatively moist environment in the winter (AC for heating is bad; radiators are much better). For the summer, try not to sweat because sweating induces itching (AC is great then). Air pollution can make matters worse. In Israel, for example, there are dusty days ("ovech" in Hebrew); try to stay indoors in those days.
   
5. Stay cool in the other sense as well. Stress, anger and emotional pressure can worsen the situation. I know it sounds impossible, but try to keep your cool. Different approaches on this one, including my own varied attempts, but meditation and self-hypnosis can help to extend calm further. Work out your issues if you have any. See a shrink if you need one. Whatever works for you.
   
6. Keep your hands and your mind busy... I don't mean that you need to be a workaholic (or any other -holic either). But anything that makes you feel good and keeps you busy enough to forget scratching, is worth doing. Hand-engaging hobbies that you love may serve a double purpose by keeping both your mind and your hands off scratching.
   

Again, I want to stress that these methods are not likely to improve your situation once it is bad. But apply them at all times and you may just help yourself - if not totally preventing, they will certainly slow down any potential deterioration in your situation and possibly keep status quo.

Still, don't forget that when things get bad, you need to actually treat the situation. Here's a reminder for how to recognize things are going bad.
