I could suggest you treat allergies like you treat fear – face them head on. But that is probably not good advice since people tend to have serious allergic reactions. The best tip is to avoid getting allergies in the first place. Avoid running into the elements that are causing your allergies.
For pollen, cut the plants if they are too close to the windows. During the day, make sure the wind is not blowing in too many foreign particles through the windows. If you have a flower garden, keep it a safe distance from the house.
If the problem lies in your pet, who keeps bringing in dirt and debris from the outdoors, leave the pet outside. You cannot tell an animal to be sensitive to your allergies, but you can apply discipline.
Dust is another allergy-causing element that collects in the house and seems to disappear from sight. Dust the areas that are collecting too much of it. All you need are gloves, a surgical mask and a duster. Afterwards, keep the window open to let the dust out.
Overall, find all possible sources of your allergen and remove them. No matter how bad your allergies are, you can prevent these problems from happening.
