The ragweed season is underway in Minnesota, and experts say it’s likely to last longer than usual this year. That’s thanks to the mild winter, the unusually warm spring, and heavy rains at various times this summer. Doctors across the state are reporting an increase in ragweed sufferers due to the earlier season and higher pollen counts. It takes a killer frost to end the ragweed season, which is unlikely anytime soon. Doctors recommend sleeping with the windows closed if you have symptoms, and if that doesn’t provide enough relief, there are numerous over-the-counter medications. Some people may need to see a specialist.
