Anxiety is a common problem, and it can affect anyone. Anxiety is an emotion that stems from fear or worry and causes physical symptoms such as sweating, dizziness, nausea, and more. This can happen in your brain or body. In this post, we will explore how anxiety affects the body and what you can do to help prevent it!

How does anxiety affect the body?

Anxiety affects the body in several ways.

Your body is affected by anxiety in several ways. Anxiety can be uncomfortable and hard to control, which can lead to other problems.

Anxiety affects your gut in two ways:

  • Anxiety causes stress on the vagus nerve (the first part of the brain that controls your heart rate), which can slow down digestion and make you feel bloated or full after eating just a few bites of food. This effect is temporary but often leads people with anxiety disorders who have a high level of stress hormones in their bodies (such as cortisol) instead of serotonin levels which are higher than normal for healthy individuals with no mental health issues at all!


Hyperventilation is a common symptom of anxiety, and it can be caused by breathing too quickly and/or too deeply. You may not even be aware that you are doing it—for example, if you’re nervous about speaking in public. This makes sense since breathing faster increases carbon dioxide levels in your bloodstream (a sign of anxiety), which leads to an increase in acidity in the blood vessels—and this causes dizziness or fainting spells!

When hyperventilation occurs during panic attacks or other episodes of extreme stress, it can lead to shortness of breath and chest pain as well as a rapid heartbeat.

Your heart rate will pick up because there’s more work being done on its behalf by pumping blood faster around your body; however, taking deep breaths from time to time will help keep things under control so that no damage occurs due to overworking itself unnecessarily.

Muscle tension, tremors, and aches or pains

  • Muscle tension, tremors, and aches or pains
  • Anxiety can cause muscle tension and pain. This is because anxiety causes your body to become tense and move more slowly than usual. These effects may be felt as a tingling sensation in the arms and legs, especially when you’re sitting still for long periods. You may also experience twitching in your fingers, toes, or face that’s due to muscle tension as well (this phenomenon is also known as “muscle jerks”).
  • How to reduce muscle tension after an episode of anxiety? The best way is to take steps toward reducing your stress level by doing things that make you feel good about yourself like exercising regularly and spending time outdoors with friends or family members who love you unconditionally—allowing yourself this type of comfort will help keep your mind off negative thoughts about yourself which leads us into part two:

Difficulty swallowing or a lump in your throat

When you have anxiety, it can be difficult to swallow because of the increased difficulty in breathing.

This is especially true if you are on the verge of panic attacks. You may also experience dry mouth as well as hoarseness, which can lead to difficulty with swallowing as well. A doctor will help determine whether these symptoms are caused by anxiety or something else like acid reflux or arthritis pain.

Dizziness or spacey feeling

As you may have experienced, it can be hard to concentrate or focus when you’re anxious and worried. In fact, many people find that their brain is “fuzzy” when they feel anxious.

This feeling of being out of sync with the rest of your body could be caused by several things, such as stress hormones like cortisol or adrenaline flooding your system. The result? Your body feels strange—you balance on one foot while walking down the street (or upstairs), something that would normally cause no problem for most people!

This can also lead to dizziness or spacey feelings in general; if someone were to ask why they feel off balance all the time during stressful situations at work or home life then this could be an explanation.

Shortness of breath

As you breathe, your heart rate increases and the blood vessels in your body expand. This can cause shortness of breath as well as chest tightness, which may feel like a feeling of not getting enough air into your lungs.

You may also notice that breathing through your mouth feels easier than breathing through other parts of your body like the nose or mouth (or both) because there aren’t any muscles involved in this process.

Dry mouth and frequent urination

  • Dry mouth can be a result of increased saliva production.
  • Frequent urination is a sign your body is producing more urine as a way to regulate itself. But if you find yourself breaking out in cold sweats, or experiencing chest pain or shortness of breath while breathing deeply, it’s time to call 911!

Sweating and chills

Sweating and chills are symptoms of anxiety. They can also occur when you’re stressed or nervous. Anxiety may cause excessive sweating or chills in some people. Sweating is your body’s way of cooling itself. It may happen when you’re anxious, stressed, or nervous.

Chills happen when your body temperature drops due to fear or shock. This can occur during intense situations like an attack. Chilling out won’t help with anxiety relief because it doesn’t address the cause. Instead, it focuses on how to stop feeling scared/nervous/shocked after something bad happens.

Nausea, diarrhea, or irritable bowel syndrome (IBS)

If you’re experiencing nausea or diarrhea, it’s important to remember that these symptoms are not caused by anxiety. Nausea and diarrhea can be caused by anxiety or other things like a stomach bug or food poisoning.

However, there are steps you can take to treat your symptoms:

  • Drink fluids (water, milk) regularly until your body feels better. You may feel bloated or gassy if this is happening—it’s normal!
  • Take anti-nausea medication if needed (it will make things worse). Talk with your doctor about what dosage would work best for you. Some anti-nausea drugs can cause constipation as well so talk about how much relief from vomiting vs diarrhea vs constipation matters most.

Anxiety affects the body in several ways.

Anxiety causes dizziness, shortness of breath, and nausea. It can also cause shakiness, sweating, and an increased heart rate. Dry mouth and fainting are also possible if anxiety is intense and prolonged.

The symptoms of an anxiety attack can be similar to a heart attack. This includes shortness of breath, a feeling of pressure in the chest, and chest pain lasting more than 3 minutes.

Sweating excessively during an anxiety attack lasting over 15 minutes is also possible.


Very soon, I will be posting about the physical symptoms of anxiety. If you are interested in learning more about anxiety and its physical effects, please consider reading my other posts.

Anxiety can be incredibly debilitating. When you’re suffering from it, you feel like everything is out of control and there’s no way back. It can make you feel like your life is falling apart, and a lot of people turn to drugs or alcohol as a way out. But there are ways around this problem that don’t involve using any kind of substance at all!
