An allergic reaction can flip your entire day upside down. From sneezes and sniffles to swelling and itching, even mild symptoms can make it hard to function as usual.

Allergies affect more than 50 million Americans every year.1 While we don’t know for sure how they affect our mental health, research suggests there’s a link.2

How allergies can impact emotions

Your physical health is intricately connected to your emotional health, and they can influence each other.3 How you feel physically can have a ripple effect on your mind and your mood, so it’s normal for allergy symptoms to make you feel a little grumpy or unmotivated.

Consider how these common symptoms might take a toll on your emotions:

These very real, valid feelings shouldn’t be dismissed or ignored. Most people feel better once their allergy symptoms improve, but that’s not always the case.

Can allergies cause mental health problems?

Overall, research isn’t totally conclusive. Some studies suggest people with certain allergies are more prone to conditions like anxiety or depression, while a recent study looking at genetic information and disease outcomes found no evidence that allergies directly cause mental health concerns.6

Although experts haven’t yet drawn strong conclusions, there are a few possible explanations of the ways allergies might play a role in mental health.

  • Cytokines, pro- and anti-inflammatory molecules released by the body’s immune system during allergic reactions, are known to affect the brain and emotions.7
  • Some antihistamines can affect your mood and sleep.8
  • Symptoms that are physically uncomfortable and distracting can contribute to stress, insomnia, and negative moods.

How about severe allergies?

Anaphylaxis is a life-threatening allergic reaction that can happen suddenly. It can be caused by severe allergies to certain foods, insect stings, latex, or medications. Having severe allergies can be very worrying, and having to avoid allergens can take a major toll on your mental health.

For some people, it’s an everyday reality to avoid social settings where serious allergies could be an issue, or to worry about whether a situation is safe. It’s no wonder that children with food allergies are more likely to struggle with higher levels of anxiety, compared to those without them.9 For parents who constantly have to assess kids’ environments for allergen risks, distress can make it hard to function in everyday life.10

Treating allergies may help boost mental health

Symptoms of some allergies, like asthma or hay fever, can be treated. With fewer or less severe symptoms bogging you down physically, you’re likely to feel a lot better emotionally. People who don’t treat their allergies tend to be at higher risk for anxiety, depression, and mood disorders than people who do treat them.11

Common types of medications used to treat allergies include antihistamines, decongestants, nasal sprays, steroids, and mast cell stabilizers. Many of these can be bought over the counter, but medications such as inhalers require a prescription. For nasal symptoms, sterile saline sprays can help clear congestion.12 In some cases, allergy shots, a type of immunotherapy, can offer long-term relief.13

Strategies for coping with severe allergies

Severe allergies can make everyday situations and environments feel like potential threats. To ease the way, try one of these effective strategies to help reduce anxiety.14

Parents of kids with severe allergies can help by:

  • Creating a plan with their child that helps them stay safe and feel comfortable, confident, and in control
  • Helping kids understand when and how to ask an adult for help
  • Teaching children relaxation techniques, such as deep breathing or progressive muscle relaxation, to use when they’re worried about having a reaction
  • Learning how to tailor information for teenagers who may be transitioning from parental to self-management of their allergies

If you or a loved one have severe allergies, you may benefit from:

  • Educating yourself about the real risks of allergies by seeking accurate information from reliable sources
  • Recognizing your own psychological distress and seeking support from family, friends, or a mental health professional
  • Seeking proper guidance on how to use epinephrine injectors
  • Considering immunotherapy for allergies
  • Advocating for food labeling and public awareness of severe allergies and anaphylaxis
  • Understanding that anxiety is normal in the first few months after an anaphylactic event, and you can take steps to move forward

Lifestyle changes go a long way

Whether you treat your allergies with medication or not, it’s beneficial to reduce your exposure to potential allergens and limit their impact. Depending on your allergies, you may want to:

Avoid triggers. If you’re allergic to pollen, for instance, try to stay indoors when the pollen count is high, or avoid opening the windows during times of the day when pollen is most likely to be in the air.

Clean regularly. Dust mites, mold spores, and pet dander are all common allergens found in homes. You can reduce their impact by vacuuming regularly, washing bedding weekly, and using a HEPA air purifier to filter the air.

Eat healthfully. Nutritious foods can boost your immune system and reduce inflammation.15 Be sure to include plenty of fruits, vegetables, whole grains, lean protein sources, and omega-3 fatty acids.

Talk to a doctor if you’re interested in alternative remedies. While a few alternative treatments may help ease seasonal allergy symptoms, others don’t have good evidence that they work.16 Consult with a medical professional to make sure any supplements you’d like to try are effective and safe. This is especially important if you take medications.

Try to reduce stress. Stress can worsen allergy symptoms.17 Consider practices like mindfulness and meditation to help you slow down. These and other kinds of self-care—such as getting good sleep and nutrition, socializing, moving your body, treating health problems, setting healthy boundaries, and doing things that give you joy and purpose—are essential tools for managing stress.

If you think allergies may be affecting your mental health, talk to your doctor or a mental health professional about how to manage them. Something else could be going on, so it’s best to get checked out by a professional.
