Anything that irritates your lungs and brings on the symptoms of asthma is considered to be a ‘trigger’. By understanding your triggers, you can be better prepared to prevent asthma symptoms or act fast to stop them getting worse.


Stress and anxiety


The body’s response to stress and anxiety can cause asthma symptoms to worsen. To prevent this, try and avoid situations known to cause you stress and anxiety. If you feel stressed or anxious, treat yourself to a gentle walk or try relaxation exercises such as five minutes of medication. It’s also advisable to limit your alcohol intake as this is known to increase stress and anxiety.



Exercise is good for you but can trigger asthma symptoms; always use your reliever inhaler before you start to exercise. Even mild exercise causes you to breathe harder resulting in cooler, drier air reaching your lungs which causes irritation.



It’s not advisable to smoke regardless of asthma, however, if you do have asthma and you smoke, you will find that smoking makes your symptoms worse. If you need help to quit the nicotine, pay a visit to your local LloydsPharmacy and ask about the many nicotine replacement therapies available.

An increase in temperature and humidity – moisture in the air – can cause aggravate asthma symptoms. If the forecast predicts these conditions or you’re travelling to a country known to have a hot and humid climate, always carry your reliever inhaler

Hay fever

If you have asthma, you’re more likely to experience hay fever or other allergies. If this is you, keep an eye on pollen counts and start take treatments a week before the hay fever season is due to commence.
