Several studies have found an association between allergies and depression. This connection is not completely understood, although some symptoms of allergies, such as fatigue or difficulty sleeping due to congestion, may contribute to depression.
This article reviews the allergy-depression connection, how to treat depression, and tips for improving your mental health.
How Are Allergies and Depression Linked?
Several studies have shown a link between allergic rhinitis (hay fever) and mood disorders, including depression.
The cause of this is not completely clear, but studies suggest a genetic component between allergies and mental health conditions, like depression. Another hypothesis is that inflammatory chemical mediators, such as cytokines, may be responsible.
Poor sleep caused by allergy symptoms may also lead to depression, as well as side effects caused by allergy medications.
How to Improve Mental and Physical Health
The following are some tips for improving the mental and physical health of people suffering from allergies and depression, or for people who are concerned about the risk of these conditions:
Persistent sadnessDisinterest in daily activitiesFeelings of worthlessness or hopelessnessTrouble concentratingLoss of appetite
Get enough sleep. If you have trouble sleeping due to allergy symptoms, such as congestion or even sleep apnea, work with a qualified healthcare provider to resolve these issues and improve your sleep quality. Get plenty of exercise. Outdoors may be best, but individuals with pollen allergies may benefit from exercising indoors while pollen counts are high. Eat a balanced diet. Practice positive thinking, and consider meditation or other relaxation techniques. Reach out to friends and family for support.
Don’t hesitate to get help from a qualified mental health professional, if necessary. Psychotherapy (talk therapy), particularly cognitive behavioral therapy (CBT), has been proven effective in treating depression.
What If Improving My Allergies Worsens My Mental Health?
Most allergy treatments are unlikely to worsen your mental health.
However, certain medications used to treat allergies have been linked to depression or are known to interact with medications used to treat mood disorders, including depression or bipolar disorder.
For this reason, it’s important that you consult with your healthcare provider, as well as your pharmacist, so they can review each medication you’re using and provide options that preserve your mental health while treating your allergies.
Any time you start a new medication—for either allergies, depression, or another mood disorder—review your complete medication list with your healthcare provider to ensure it is unlikely to interfere with the other medications you are taking. Do not assume your healthcare provider is aware of every medication you are on.
If your allergy medication is causing depression, you may be able to treat your allergies with a different medication that is less likely to cause this side effect. For example, intranasal sprays for congestion are less likely to cause side effects than a systemic antihistamine that affects the whole body, because less of the medication is absorbed into the bloodstream.
Depression Treatment
There are different types of depression, including:
Major depressive disorder (MDD) Bipolar depression Seasonal affective disorder (SAD) Postpartum depression Persistent depressive disorder (PDD) Psychotic depression
While there is some overlap, treatment varies depending on the type of depression you are diagnosed with.
All types of depression typically are treated with a combination of:
Psychotherapy, particularly CBT Medications, like selective serotonin reuptake inhibitors (SSRIs) Counseling and lifestyle adjustments, such as getting good quality sleep or increasing physical activity
Getting Help
Getting help for depression often starts with contacting your healthcare provider.
Depression is a common condition, so many healthcare providers have experience treating it and can provide you with other resources as necessary. You may need to find a mental health counselor or therapist, but your regular healthcare provider can provide you with recommendations.
If you have healthcare insurance, your insurance company may offer a list of providers that will accept your insurance.
Summary
Both allergies and depression are common conditions capable of seriously impairing your quality of life and ability to complete everyday activities. Research suggests a link between the two.
Both conditions can be treated, but sometimes medications used to treat allergies and depression can interact in a negative way. When this occurs, work with a healthcare provider to find a solution that treats both conditions while minimizing negative side effects.
A Word From Verywell
Allergies and depression are both serious healthcare conditions that can be challenging to cope with. However, there are several available resources and treatment options to address them. Treatment should not be delayed, as both conditions can worsen if ignored. The sooner you reach out for help, the sooner you can feel like yourself again.
