“Only the arrival of a rainy period will bring relief to those with allergies,” the organisation warns. “However, it is necessary to be wary because if rain does clear the sky of pollens, storms could encourage respiratory discomfort and asthma attacks.”

It is estimated that 18 million people in France are allergic to grass pollens.
