ep 126 - Seasonal Allergies and Sleep Problems — Causes, Treatments, and Medication Effects

If allergy season leaves you feeling exhausted even after a full night's sleep, you're not imagining it. Seasonal allergies can disrupt sleep quality through histamine release, inflammation, and nighttime congestion that fragments deep sleep. In this video, we explore how allergies affect sleep architecture, why histamine increases wakefulness, and how different types of allergy medications — including diphenhydramine (Benadryl), cetirizine (Zyrtec), loratadine (Claritin), fexofenadine (Allegra), nasal steroids, and decongestants — may impact drowsiness and next-day alertness. Learn practical strategies to improve sleep during allergy season, including medication timing, environmental controls, and ways to reduce nighttime inflammation. If you struggle with allergy fatigue, brain fog, or restless sleep during high pollen months, this evidence-based discussion will help you make more informed choices for better rest and better health.
