If you find you struggle to snooze during the springtime and summer months, it may be because your allergies are affecting your sleep.

“Almost half of people who suffer from seasonal allergies experience sleep difficulties. Allergy sufferers take longer to fall asleep at night, and wake up more often during sleep that those without allergies,” Dr. Holly Phillips, a board-certified general internist.

“If you have allergic symptoms during the day, and you are having trouble sleeping at night, it is most likely that the histamine being produced is causing your brain to stay on high alert,” Dr. Jim LaValle, a clinical pharmacist and board certified clinical nutritionist, tells Bustle.
