Do Allergies Make You Sick and Tired?

How allergies leave you feeling sick and fatigued

Allergies don’t just trigger sneezing and congestion, they can take a toll on your entire body. When your immune system overreacts to allergens, it produces inflammation throughout your system, leading to a variety of frustrating symptoms. Common allergies include:

  • Pollen (from trees, grass, and weeds like ragweed)
  • Dust mites
  • Pet dander (dogs, cats, and other animals)
  • Mold spores
  • Cockroach droppings
  • Food allergies (such as nuts, dairy, shellfish, soy, and eggs)
  • Perfumes and strong odors
  • Smoke and air pollution

These allergens can cause symptoms like rhinitis, congestion, headaches, brain fog, fatigue, and even trouble sleeping—making it feel like you’re constantly battling a cold.

Many people also experience allergic asthma, which can lead to breathing difficulties, wheezing, and a persistent cough. Over time, untreated allergies can contribute to sinus infections, chronic fatigue syndrome, and even weakened immune responses, making you more susceptible to colds and other infections.

If you frequently wake up feeling congested or have difficulty breathing through your nose, your allergies could be affecting your sleep, leading to excessive daytime drowsiness, irritability, and difficulty concentrating.

How to manage allergies at home

Even with proper medical care, managing allergies in your daily life can make a big difference. Some tips to reduce exposure to allergens include:

  • Keep windows closed during high pollen seasons
  • Use HEPA filters in your home and car
  • Wash bedding and vacuum regularly to remove dust mites
  • Limit pet exposure if dander is a trigger
  • Wear sunglasses and hats outdoors to keep pollen away from your face
  • Take showers after spending time outside to remove allergens from hair and skin
  • Use a humidifier to maintain moisture in dry indoor air
