It Isn’t All In Your Head


His palms are sweaty, knees weak, arms are heavy
There’s vomit on his sweater already, mom’s spaghetti
He’s nervous, but on the surface he looks calm and ready
To drop bombs, but he keeps on forgettin’
What he wrote down, the whole crowd goes so loud
He opens his mouth, but the words won’t come out

Yes, those are lyrics to Eminem’s song “Lose Yourself.” Yes, this song is a banger, but that’s not why I have it on the blog post. I think that these lyrics perfectly embody the physical symptoms associated with stress and anxiety.

When we talk about anxiety or stress, we may think of intrusive thoughts and constant worry. What we don’t realize is that anxiety and stress can have an impact not only on our thoughts or emotions, but also on our bodies. Anxiety and stress can manifest itself in many ways. What we should keep in mind is that not all anxiety and stress is bad for us. Actually, some stress and anxiety is good. It allows us to be alert and it can sometimes give us the motivation to complete tasks. The issue with stress and anxiety occurs when it is persistent and elevated. Below we will discuss the biological systems that are affected by stress and anxiety, as well as how to combat them.


Biology of Stress and Anxiety

When we are stressed out or anxious, our body has a reaction. The effects of stress and anxiety can disrupt our Nervous System, Musculoskeletal System, Respiratory System, Cardiovascular System, Endocrine System, Gastrointestinal System, and Reproductive System. It pretty much affects your entire body. We will go through each of these systems and see how stress and anxiety directly relate to the function of these different systems.

Nervous System

The nervous system is where our ‘flight, fight, or freeze’ response lives. When our mind and body are under stress or anxiety, this shifts our body to resourcing our energy to combat the stress or anxiety. This then turns on the ‘flight, fight, or freeze’ response, also called the sympathetic nervous system. This system will cause our body to release adrenaline and cortisol. These two hormones will make our heart beat faster, raise blood pressure, and change digestive processes. All of these systems will go back to normal once the ‘crisis’ has passed.

Musculoskeletal System

The musculoskeletal system can also be affected by stress or anxiety. This system is made up of cartilage, bones, joints, tendons, and ligaments. All of these parts provide stability, support, and movement in our body. When we are stressed or anxious, this may cause our bodies to tense up. Our muscles contracting for long periods of time may cause headaches, migraines, teeth grinding, or muscle cramping/pain. These symptoms should pass after the stressor is gone, but having constant muscle tension could cause the pain to linger.

Respiratory System

The respiratory system is made up of the airways, the lungs, and the muscles of respiration. This system is what allows us to inhale oxygen and exhale carbon dioxide. When we are anxious or stressed out, our respiratory system may be disturbed. Stress and anxiety may make it harder to breathe. This then can cause us to hyperventilate or cause panic attacks. This could be a really scary experience because it feels like you aren’t able to get enough oxygen.

Cardiovascular System

The cardiovascular system consists of the heart and the circulatory system. This system pumps blood to the organs, tissues, and cells of your body. Stress or anxiety may cause an increase in heart rate and stronger contractions in the heart muscle. The blood vessels that direct the blood to the larger muscle groups and to the heart dilate, which increases the amount of blood pumped to these parts of the body. This also increases blood pressure. If you are chronically stressed or anxious, this could cause the cardiovascular system to be negatively affected. The effects may cause a higher risk of hypertension, heart attack, or stroke.

Endocrine System

The endocrine system is made up of glands that produce and secrete hormones. These hormones help regulate the body’s growth, metabolism, and sexual development. When our body is stressed, our nervous system may signal our endocrine system to release the ‘stress hormones.’ These hormones are cortisol and norepinephrine. When these hormones are released, this causes your liver to create more glucose. This glucose acts as energy to help you react during a flight, fight, or freeze response. High levels of cortisol and norepinephrine may cause too much blood sugar, high blood pressure, and a suppressed immune system.

Gastrointestinal System

The gastrointestinal system, also known as the digestive system, is made up of the esophagus, stomach, small intestine, large intestine, and the rectum. Stress and anxiety can cause a lot of issues with your digestion. When we are stressed or anxious it may cause us to eat more or less. This could lead to heartburn or acid reflux. Stress and anxiety may also lead to a more sensitive stomach. You may have nausea or pain, and when the stress or anxiety is severe, it may even cause you to vomit. Constant anxiety or stress can lead to stomach ulcers as well. Stress and anxiety may also cause digestion issues. You may find yourself being constipated or having diarrhea when anxious or stressed.

Reproductive System

Lastly we have the reproductive system. The reproductive system is different for both men and women, but both can be affected by stress and anxiety. For men, constant stress or anxiety may cause a decline in testosterone production, sperm production, or maturation. Chronic stress and anxiety may cause impotence or erectile dysfunction. For women, stress and anxiety can affect their menstrual cycle, PMS symptoms, menopause, and sexual desire. Their menstrual cycle may become irregular or absent with high levels of anxiety or stress. With stress and anxiety, women may have a more difficult time coping with PMS symptoms. If women are going though menopause and are highly stressed or anxious, it may cause the physical symptoms of menopause to be worse. Finally, if women are too stressed or anxious, it may cause them to have a lesser desire for sex.


Anxiety and Stress Reducing Tools

There are many ways that we can relax or destress. Self care is super important, but keep in mind that what may work for one person, may not work for another. Below are some tips and ideas of how to reduce anxiety and stress.
