A hay fever cough can linger for longer than expected when pollen levels are high, and many people believe they've been taken down by a summer cold. But, it's a very normal sign of seasonal allergies.
A hay fever cough is caused by excess mucus dripping down the back of your throat (postnasal drip), creating a tickle, which can lead to a cough. Hayfever can also worsen asthma for sufferers due to the inflammation in the airways. This isn’t much fun at a time of year when we all enjoy spending more time outside.
