You were diagnosed with an asthma attack. Your health care provider can help you make a plan to manage your asthma. Doing so will help you have fewer visits to the emergency room. And it will help you have fewer hospital stays.

• Take your asthma medicines exactly as your health care provider tells you. Do this even if you feel that your asthma is under control.
• Always use your medicine delivery system the right way. Be sure to use the correct inhaler methods for your device. Refer to the information that came with your medicine. Talk to your provider if you have any questions about how to use the device. This includes a metered dose inhaler or nebulizer.
• Stay away from triggers that cause asthma flare-ups or symptoms.
• Tell your health care provider, asthma provider, or allergy provider if you've been diagnosed with a new or past health condition or disease.
• You may feel depressed or anxious. If so, tell your provider, asthma provider, or allergy provider.
• Learn how to watch your asthma. Some people watch for early changes in symptoms getting worse. Some use a peak flow meter. Write down your symptoms and peak flow readings in a diary. Your provider, asthma provider, or allergy provider should give you an Asthma Action Plan.
• Always have a quick-relief inhaler with you. If you were given a prescription, make sure to get it filled as soon as possible.
• Stay at a healthy weight. Being overweight can affect how well your asthma is controlled. Work with your provider to find out the best weight for you.
• Don't be afraid to exercise. It may make you short of breath. But it can make breathing muscles stronger. It can also give you more energy. Walking is a good way to get oxygen moving all over your body. Ask your provider about safe exercises for you.
• Eat plenty of fruits and vegetables.
• Do breathing exercises. Learn how to do belly breathing and pursed-lip breathing. These methods can help you breathe better. Taking slow, deep breaths at any time can give you more of the oxygen you need. Ask your provider about breathing exercises for you.

Triggers are those things that make your asthma symptoms worse or that cause asthma attacks. Many people with asthma have allergies that can be triggers. You may need allergy tests. These are done to find out what you are allergic to. This can help you stay away from triggers.

Dust or dust mites are a common asthma trigger. To stay away from dust mites:

• Use dust-proof covers on your mattress and pillows. Wash bed sheets and blankets once a week in very hot water.
• Don't sleep or lie on cloth-covered cushions or furniture.
• Ask someone else to vacuum and dust your house, if you can. Do this on a regular schedule.
• Wear a dust mask if you have to vacuum and dust your house. You can buy them from the hardware store.
• Use a vacuum with a double-layered bag or HEPA (high-efficiency particulate air) filter.

Pets with fur or feathers are triggers for some people. If you have pets, take these safety steps:

• Keep pets out of your bedroom and off your bed. Keep the bedroom door closed.
• Don't use carpets. And don't have cloth-covered furniture in your home. If this is not possible, keep pets out of rooms with these items. Vacuum the furniture on a regular basis.
• Have someone bathe your pets every week. And brush them regularly.

If you smoke, do your best to quit:

• Join a stop-smoking program. This can increase your chance of success.
• Ask your health care provider about medicines or other methods to help you quit.
• Ask family members to quit smoking, as well.
• Don't let anyone smoke in your home, in your car, or around you.
• Don't use e-cigarettes.

Take these steps to limit exposure to air pollution:

• Don't exercise in high-traffic areas.
• Check the color-coded Air Quality Index daily. Limit outdoor activities when the index is orange.
• Stay inside when the index is red, purple, or maroon.

Exercise can be a trigger for some people:

• Know what to do if exercise is a trigger for you. Ask your provider if you should use medicine before you exercise. Many people use quick-relief inhalers.

Weather or pollen can make asthma symptoms worse:

• Try to keep your windows closed during pollen seasons. And keep the windows closed when mold counts are high.
• On cold or windy days, cover your nose and mouth with a scarf.

• Stay up to date on all vaccines as advised by your health care provider.
• Wash your hands often with soap and clean, running water. Or use an alcohol-based hand sanitizer.
• Try to stay away from people who are sick. And stay away from crowds during cold and flu season. Respiratory infections, such as colds or the flu, may set off your asthma.
• Use your quick-relief medicines as soon as you start to have respiratory symptoms. These include a sore throat, a cough, or a runny or stuffy nose.

Make a follow-up appointment as directed. Follow your Asthma Action Plan, if you have one. Your health care providers will teach you how to manage your asthma. This may include quitting smoking advice and breathing exercises. It may also include ways to stay away from your triggers. This information can help you reduce asthma flare-ups. And it can help you manage your symptoms.
