People with asthma are at risk of 'life-threatening' attacks when pollen levels are high, a charity has warned.
Asthma and Lung UK is telling asthma sufferers to have a reliever inhaler on hand at all times and to continue using preventer inhalers.
The charity says more than three million people in the UK have lung conditions such as asthma or chronic obstructive pulmonary disease (COPD) and are at risk of attacks or flare-ups.
