DETROIT – While tree pollen is common trigger for those who are stuck with springtime allergies, there are other triggers that can cause symptoms, too.

However, it is the tree pollen that’s once again wreaking the most havoc this week in Metro Detroit.

If your allergy symptoms are currently acting up -- like the congestion, runny nose, throat irritation, sinus pressure, etc. -- it’s likely you’re sensitive to tree pollen. Experts at The Weather Channel say tree pollen was very high on Monday, April 24, which set off an array of symptoms for many.

Grass pollen and ragweed pollen were not expected to be present Monday, Tuesday or Wednesday this week, so anyone specifically sensitive to those allergens shouldn’t worry, at least for a few days. Allergens from mold and mildew also remain low in the area.

But the tree pollen is forecast to stick around for the near future. Tree pollen was to be low on Tuesday, April 25, and then will become high again on Wednesday and Thursday.

Over the next week, the general risk of allergy symptoms is considered mostly moderate for the Detroit area based on the weather outlook. That risk is expected to increase to “high,” though, on April 27 before decreasing again on April 30.

Allergy season is getting longer every year in Metro Detroit. Data shows that allergy season has grown by 29 days since 1970, and it’s only expected to get worse due to climate change.

Experts encourage people with a known history of allergies to begin their typical medications as early as they can. People with springtime allergies are also encouraged to resist the urge to open their windows when the weather is nice, and to change their clothes and shower after spending time outside.

If you’re getting recurring sinus infections, if the allergies impact your breathing, or if over the counter medications aren’t offering relief, experts suggest visiting an allergist. People who are mixing multiple allergy medications should seek expert help to determine the best plan of action, as some allergy medications are not safe if mixed together.
