Certain asthma triggers can set off a cascade of asthma symptoms. Asthma triggers might include dust mites, air pollution, cold air, a cold virus, sinusitis and asthma, cigarette smoke and fragrances, among others. It is vital to learn to identify your triggers.
What to do
- Take your reliever inhaler (usually blue) straight away and try to breathe deeply and steadily
- Sit down and loosen any tight clothing
- If your symptoms haven't improved after five minutes, or you're worried, call 105910 or see a doctor urgently
- Continue to take puffs of your reliever inhaler every minute until help arrives
