Light rain showers will wash pollen away, helping it to stop travelling through the air.
However Avogel says that humid thunder storms can be problematic for those with hay fever because it can cause pollen grains to gain water and then burst open.
This releases smaller pollen grain into the air meaning there is a higher pollen count.
Also, on windy days pollen can spread and travel further which can be harmful to hay fever sufferers.
The aafa website says: “When it rains when grass and weed pollen is high, drops can hit the ground and break up clumps of pollen into smaller particles.”
They then disperse quickly, causing a sudden increase in allergy symptoms, including allergic asthma symptoms during the downpour.
If it is a rainy and humid season, mould and dust mite allergies can increase.
This is because mould thrives in damp conditions. Dust mites can also thrive in humid conditions.
While rain can be a temporary relief from allergy symptoms, medication is advised to have long-term effects.
Medication includes antihistamines, eye drop and nasal sprays.
These can all be purchased over the counter at your local pharmacy and should help alleviate hay fever symptoms.
Other things you can do to help your symptoms include keeping your windows shut on high pollen days and if you have to go outside, make sure you change immediately when arriving home and take a shower to get rid of any pollen that has become stuck to you.
Changing bed sheets regularly can also help you sleep better to remove any dust or pollen that may have become stuck to your bed sheets.
