Hay Fever and Sleepiness: Understanding the Connection

Why Hay Fever Causes Sleepiness

Histamine release: Fights allergens but causes drowsiness.
Antihistamine side effects: Many allergy meds cause drowsiness.
Sleep disruption: Congestion, itching, sneezing fragment sleep; poor sleep worsens allergies.

Take meds as directed; ask doctor about non-drowsy options.
Exercise regularly—improves immunity and sleep.
Optimize sleep environment: dark, quiet, cool; no caffeine/alcohol before bed; consistent schedule.
