Can Hay Fever Be Affected By Temperature?

It’s that time of year again when half the nation seems to sneeze and splutter their way through the day. Yes, it’s hay fever season and if you happen to be allergic to pollen you will know exactly how bad it can make you feel. But how much of a bearing does the weather have on hay fever symptoms?

Generally speaking the hay fever season only starts when the temperature starts to warm up. There is no specific temperature that applies but once the winter is over and warmer temperatures arrive with the spring, plants and flowers start to do their thing and release pollen. Different plants release their pollen at different times of the year and that means as the season goes on it can be more problematic for hay fever sufferers.

Another reason why hotter temperatures mean more hay fever is because plants release more of their pollen when the temperature rises. The hotter it gets, the more pollen they release. That’s why hay fever sufferers are often happier in cooler weather when the clouds roll in. It provides something of a respite from their symptoms. Sunshine also plays a part in this but temperatures do have a role to play as well.

It does depend a little on where you are as well though. For example if you are on the coast you are likely to find it easier to manage your symptoms. The presence of the sea generally makes it slightly less troublesome than you’d expect elsewhere. It doesn’t always follow because it depends on how breezy it is and what direction the wind is blowing in, but generally you can expect an easier time of it.

You might think then that rain would be the most welcome thing to happen, but it doesn’t follow that this is the case either. A lot of the pollen hangs in the air and if it rains the moisture brings that pollen down. Of course rain also has the effect of cooling things down a little so in this respect you might find your hay fever symptoms do get better. Think of a storm for example, which generally cools down the temperature quite a bit. This will make things easier and also means the plants will reduce the amount of pollen they emit, thanks to the coolness.

As you can see it doesn’t matter whether you measure the temperature in Celcius or Fahrenheit. The one thing that matters is how high those figures go. This is why you will usually see the pollen count measured alongside other crucial weather facts including the temperature. From now on, check and see how the pollen count runs alongside how hot it will be. It’s quite interesting to see how closely they run together.
