What are the symptoms to look out for when you're exercising?
When you exercise it's normal for your heart to beat faster and your breathing to be quicker. If you're doing vigorous activity you'll feel out of breath, hot and sweaty.
Make sure you can tell the difference between feeling out of breath through exercising, which is normal, and the symptoms of asthma. Then you can stop and take your reliever if you need to. Ask your doctor or nurse about what symptoms to look out for.
When exercising it's normal if:
you're breathing faster and harder
your heart is beating faster
you're feeling hot and sweaty
you're looking flushed.
Stop exercising if you:
start coughing/wheezing
are gasping for air/very short of breath/can't get enough air
feel tightness in the chest
have trouble speaking in short sentences
younger children may complain that their chest or tummy hurts.
You're having an asthma attack if any of these happen:
your reliever inhaler doesn't help
your symptoms are getting worse (cough, breathlessness, wheeze or tight chest)
you're too breathless to speak
cyanosis (a blue tinge on the skin or lips). This is a sign of lack of oxygen in the blood and means you need urgent medical attention.

If exercise triggers your asthma
Exercise can be a trigger for asthma. This can happen to anybody with asthma: children or adults, people who play sports or elite athletes.
How does exercise trigger asthma?
It's not known exactly how exercise triggers asthma. When people exercise they breathe faster. This makes it more difficult for the nose and upper airways to warm up and add moisture to the air breathed in, so the air is drier and colder than usual. It's thought that this cold, dry air in the airways triggers the symptoms of asthma.
Managing exercise-triggered asthma
Asthma shouldn't stop you doing any type of exercise as long as you:
see your doctor regularly
keep your asthma well controlled
take the right medicine
slowly build up the amount of exercise you do and the level of intensity, starting with gentle exercise before trying more vigorous activities.
Factors that may trigger asthma when exercising include:
continuous physical activity
long distance and cross country running (as this often talks place outside in cold air and without breaks)
high intensity exercise
low physical fitness
cold, dry air
recent respiratory infection
some adventure sports or outdoor activities may bring on asthma symptoms. This is more likely to be related to emotional or environmental factors associated with the activity, e.g. excitement, anxiety, stress, weather, pollen count, altitude.
fitness tests
dusty equipment
chlorine in swimming pools.
Activities less likely to trigger asthma
Activities that require short bursts of energy alternated with slower paced exercise are less likely to trigger asthma. These include:
team games such as football, hockey, netball and volleyball
badminton or table tennis, as they are slower than tennis or squash
field games, like cricket or rounders
swimming, as the warm humid air is less likely to trigger asthma, but chlorine used in pools or cold pools may be a trigger for some people
yoga, Pilates or t'ai chi, provide a workout for both your body and mind. Postures are performed in harmony with breathing techniques. Some people find that breathing techniques are helpful for their asthma. However, don't stop taking your normal asthma medicines unless your doctor or asthma nurse advises you to.
low-moderate intensity exercise, e.g. walking, cycling, yoga.
Asthma that only comes on with exercise
Some people find that they have symtoms of asthma only when they exercise and not at any other time. This is unusual and affects only a small number of people. It is sometimes called exercise-induced asthma.
What would the symptoms be?
The symptoms are the same and include coughing, wheezing, chest tightness and difficulty in breathing. Symptoms usually begin after exercise and worsen about 15 minutes after exercise stops.
If you think you have asthma that comes on only when you exercise let your GP or asthma nurse know. To help you manage your asthma they may ask you to record some peak flow readings during and after exercise.
Asthma brought on by exercise is still treated the same, usually with preventer and reliever inhalers.
