I notice I have more allergy symptoms when I’m trying to sleep. Why do my allergies get worse at night? 

Many people with nasal allergies feel that their symptoms are worse at night. Here are some common reasons why this might happen.

  1. Lying down at night can increase nasal congestion and stuffiness. Propping yourself up in bed can help with this.
  2. Your bedroom could have higher levels of allergens. This can include pet dander, dust mites, mold spores, and environmental pollen. Keep pets out of your bedroom if you are allergic to them. Learn more ways to reduce allergens in your bedroom.
  3. Some pollen counts can be higher late at night and early morning hours. Keep windows closed at these times to minimize the amount of pollen in the bedroom. Use a CERTIFIED asthma & allergy friendly® high-efficiency air cleaner. They can help remove allergens from the bedroom and improve air quality.
