As a person who suffers from asthma, chances are, you want to do everything in your power to avoid an attack. To do this, you will want to consider the following four tips:

1. Drink Water: Stay well hydrated and pay even more attention to it during certain seasons of the year when your asthma attacks are more likely to be triggered. The better hydrated you are, the more likely your system is being flushed throughout the day to keep your body in balance and avoid triggers from setting off an asthma attack. Don't forget to always bring a water bottle with you when you plan on spending the day outdoors.  
2. Avoid Pain Relievers: Certain pain relievers, such as aspirin are more likely to induce an asthma attack. If you need any pain relievers for whatever reason, talk with your doctor about what you can take. Your doctor will know what home remedies or other over-the-counter solutions will be better for you as an asthma patient.
3. Ask for Prescriptions: Be sure that you are visiting your doctor on a regular basis for prescriptions. There are always new prescriptions that are being tested and determined to help with treating asthma. On top of this, your health needs might change over time, thus leading to the need for a new kind of prescription. With regular exams done by your doctor and addressing any concerns for current prescriptions you are taking, you can be sure that you keep your asthma as treatable as possible.
4. Get a Nasal Spray: Finally, you want to be sure that you definitely have a nasal spray solution to keep your nasal passages clean and thus not irritated by certain things, such as dust and pollen that can trigger an asthma attack. Be sure that you use it regularly along with a decongestant spray when you are suffering from allergy symptoms that can lead to an asthma attack.

If you feel that you might in any way benefit from these tips, it's important to visit your primary care physician to help you further. Being diagnosed with asthma is the best way to help treat it to the best ability. Be sure to consider other changes in your home where the environment is the most controlled by you. This means taking care of your HVAC to prevent dust and pollen from circulating in the air and using a humidifier and dehumidifier when necessary.
