flag High pollen levels during exams hurt student performance, especially in math and science, a Finnish study found.

flag A Finnish study of 92,280 high school students found that higher pollen levels during exams were linked to lower test scores, especially in math and science subjects requiring focus. flag The effect was seen even at low pollen levels, with a U-shaped pattern showing declines on both high and low pollen days. flag Researchers suggest allergic reactions disrupt sleep, concentration, and mood, harming performance. flag Experts recommend starting non-sedating medications two weeks before exams and reducing exposure through measures like closing windows and showering before bed. flag They call for greater awareness and possible exam schedule changes to ensure fairer outcomes.
