Anxiety and the Immune System

Your immune system is the defense mechanism your body uses to keep you safe from bacteria and viruses. It's incredibly powerful – stronger than most people realize. Every time you ingest germs or bacteria, your body's immune system destroys it quickly, because it's trained to do whatever it takes to keep you from getting sick.

Anxiety has a complicated relationship with the immune system, and unfortunately there is some evidence that too much anxiety can actually weaken the immune system dramatically. In this article we'll explore the relationship between anxiety and immunity.

Regain Your Immune System Strength

Anxiety may be a mental health issue, but that doesn't mean it is without physical consequences. Want to strengthen your immune system? Control your stress and anxiety. Find out how with my free 7 minute anxiety test.

The Cause of a Weakened Immune System

Anxiety is essentially long term stress. It puts stress on your body with such force that you release the stress hormone cortisol in bulk all throughout your body. All types of anxiety – even those with more intermittent symptoms – cause this cortisol release. Make sure you take my anxiety test to learn more.

Now, anxiety doesn't cause you to get sick, in the sense that anxiety doesn't allow you to get germs inside your body. You still need to come in contact with viruses, bacteria, etc., in order to put yourself at risk for illness.

But when you have contact with those germs, your weakened immune system may struggle to fight them back.

How Cortisol Weakens the Immune System

Cortisol weakens your immune system for a good reason. During periods of intense stress, as though you were about to face a predator, cortisol is trying to help reduce inflammation by weakening some of the antibodies that can increase inflammation. It also turns on natural immunity (the ability to fight off problems immediately) and moves resources away from specific immunities (the ability to prevent diseases your body knows how to control).

But cortisol is only helpful in short bursts. When you experience prolonged stress, your body needs those T-cells and white blood cells, and unfortunately cortisol continues to suppress them, thus weakening your immune system over time.

The result isn't just that you may get ill. You still need to be in contact with germs and bacteria for this to occur. The main problem is that once you get sick your body will have a harder time recovering. It needs these cells to attack intruders, and it is harder for your body to do that when your anxiety is squashing your immune system strength.

Anxiety Caused By a Weak Immune System?

There is also some evidence that those with allergies may be more prone to getting anxiety, which in turn weakens the immune system and could potentially lead to more allergies.

It's not clear why this is the case. Some theories are that this occurs at a molecular level, but it's quite possible that simply living with allergies and illnesses (as one would with a weak immune system) makes life more uncomfortable and difficult, which in turn increases the likelihood of developing anxiety. Your immune system may not cause anxiety, but may instead contribute to behaviors that eventually lead to anxiety on their own.

Fight Anxiety to Improve Immune System

Curing anxiety isn't going to suddenly make you less ill. But it may help improve your immune system strength, which should help you fight off illness and infections.

There are actually some anxiety reduction strategies that can also have immune system boosting capabilities, such as:

  • Exercise – Exercise is known to improve your immune system health, and it is the number one natural way to fight anxiety. Regular exercise releases chemicals in the brain that drastically improve mood, and burns off excess energy which is known to occasionally develop into anxiety.
  • Healthy Eating and Hydration – Healthy eating and drinking more water isn't exactly an anxiety cure, but there is a great deal of evidence that unhealthy eating and dehydration seem to make anxiety symptoms worse. Thus if you want to at least reduce some of the severity of your anxiety symptoms, eating healthier and drinking the amount of water you need in a day can have a beneficial effect, and are also very important for improving immunity.
  • Massage – Massage is a known anxiety reduction strategy that also appears to have immune system benefits. It's not clear why massage boosts the immune system, but studies have shown that it appears to be effective. It's possible that massage is valuable because of its anxiety reduction benefits, but there is likely also some value to reducing pain and discomfort associated with muscle tension in a way that helps the immune system thrive.

But these are only part of the puzzle. They're anxiety reduction strategies that also improve the immune system, but if you can simply prevent your anxiety from affecting you, your immune system will benefit as a result.
