A late spring combined with an unseasonably warm May has made central Ohio one of the worst spots in the nation for allergies.

A late spring combined with an unseasonably warm May has made central Ohio one of the worst spots in the nation for allergies.

Last week, Pollen.com ranked Columbus as one of the top 10 worst cities for allergies this spring.

You can blame it on the weather, with cold temperatures in March and April delaying the onset of spring. When the flowers and trees bloomed this year, they did it all at once.

Pollen levels are high around the country, causing millions of people to suffer through one of the worst allergy seasons in memory. Folks who have never had allergies are reporting new symptoms for the first time.

Over-the-counter or prescription allergy medicines can help. But because it's such a bad season, doctors warn some people still are suffering.

Here are a few easy tips that may help reduce your suffering:

Doctors say change out of clothes you've worn to do yard work or cut the grass. Taking a shower before you go to bed may prevent pollen from coating your pillow, only to cause more irritation by morning.

For some, a shower may not be enough. Doctors recommend using a saline wash to rinse the eyes and nose before bed.

Another tip is to get a HEPA air purifier. HEPA, or High-Efficiency Particulate Arrestance, filters remove 99 percent of airborne particles such as pollen and other irritants. Even changing your furnace filter can reduce the amount of dust and pollen in your home.

One thing I can do to help you out is to bring rain. Showers cleanse the air of pollen and can bring relief.
