Those who suffer with hay fever know that it can make the otherwise enjoyable transition from winter into spring a nightmare. Along with the warmer weather and sunshine can come symptoms such as a runny nose, sneezing and eye irritation.

Trees and grasses release their pollen from April to June, making this the peak time for those with hay fever to experience symptoms. Some trees, such as willow, start releasing pollen as early as February, and some weeds continue well into September. While you may not be sensitive to all types of pollen, on days with a high pollen count (a measure of the average number of pollen grains per cubic meter squared) you may find yourself experiencing unpleasant symptoms.
