Allergies can cause all types of aggravating symptoms, from runny eyes and noses to headaches and a scratchy throat. If you have experienced fatigue, you may wonder, “Can allergies make you tired?” Here is what you need to know if you think you may have extreme fatigue from allergies.

There are many types of allergies – you can become allergic to almost anything and most allergens are substances that do not pose a real threat to your health. For unknown reasons, the body can determine that a benign substance is a health threat and set off the immune system to attack it.

When you have allergies, whether it is seasonal hay fever or allergies to dust, dander, or certain chemicals, your body works to eliminate the allergen. This causes inflammation throughout the body and a variety of symptoms. Some common symptoms include:

  • Itchy or watery eyes
  • Nasal congestion, runny nose, and post-nasal drip

  • Sore or scratchy throat
  • Rashes or itchy skin
  • Headache or sinus pressure
