It’s reductive to describe anxiety as a mental health condition. Our bodies and minds work in tandem, so that which affects one will have an impacts on the other. Despite the obvious symptoms being mental, anxiety’s effects extend to the physical, too. One of the big factors is that anxiety elevates cortisol levels—a stress hormone known to influence everything from respiratory and cardiovascular health to immune function. Sustained exposure to cortisol can hasten your body’s cellular aging.
The relationship between cortisol, stress response, and cellular aging is complex. We’re going to break it down and share the extensive health consequences of chronic anxiety. This is not meant to further discourage those who struggle with anxiety, but rather to help illuminate the severity of its effects and encourage those who suffer to seek professional help.
Anxiety Disorders Affect Millions
Anxiety disorders represent the most prevalent mental health condition in the United States, affecting approximately 40 million adults each year. There is not one singular anxiety disorder. Anxiety disorders like generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder encompass a diverse range of mental health issues, but the throughline is excessive feelings of worry and stress that disrupt daily life.
Physical Impacts of Mental Health
The physiological responses triggered by anxiety are often automatic, activating once the mind perceives stress or danger, regardless of whether the threat is real or imagined. The body’s ‘fight-or-flight’ mechanism is designed to protect us in emergencies, but when perpetually engaged due to chronic anxiety, it can lead to adverse health effects. Simply put, our bodies are not equipped to handle chronic stress.
Impact on the Respiratory System
One of the immediate physical responses to anxiety is hyperventilation. When stressed, your body tries to increase oxygen intake quickly. However, hyperventilation can be dangerous. This can cause a disturbance in oxygen and carbon dioxide balance in the bloodstream, contributing to feelings of dizziness, tingling, or numbness in the hands and feet. If sustained, this exaggerated breathing leads to lightheadedness and possibly fainting episodes.
Effects on Cardiovascular Health
On a related note, anxiety can impose considerable strain on the cardiovascular system. During an anxiety episode, the body’s heart rate increases to prepare for a rapid response and send more oxygen to the bloodstream. It’s a key element of the fight-or-flight instinct to prepare for a dangerous situation. When engaged regularly through an anxiety disorder, these surges in heart rate can lead to acute high blood pressure.
This isn’t the same as chronic hypertension, but it can lead to the same issues because these spikes damage blood vessels and adversely affect the heart and kidneys. These issues include coronary artery disease and heart attacks. Plus, stress hormones like cortisol can narrow your arteries and lead to plaque build-up. That makes it extra difficult for your body to pump blood through those arteries, leading to a whole host of heart and vein issues. All in all, anxiety disorders put quite a strain on the cardiovascular system.
Influence on Immune Function
Cortisol, when elevated over time, can suppress your body’s immune response. This makes the body more vulnerable to illness. Individuals suffering from chronic anxiety can be extra susceptible to ailments like the common cold or influenza. While short-term anxiety can sometimes temporarily enhance immune function due to an acute stress response, prolonged anxiety does the reverse, impairing your natural defenses and leaving you more exposed to frequent infections and slower recovery rates from illnesses.
Cortisol Is Complicated
Cortisol, like all hormones, has a purpose in your body. Without it, you couldn’t function normally. However, chronic anxiety brings cortisol levels in the body to an unhealthy level. When faced with prolonged emotional stress, the brain’s amygdala sends distress signals to the hypothalamus. This action kicks off a chain reaction in the sympathetic nervous system, leading to the release of cortisol and other stress hormones. Cortisol’s primary role is to prepare the body by boosting sugar levels and triglycerides in the blood. That should supply the body with extra energy to manage stress.
However, when anxiety becomes chronic, this response mechanism can become maladaptive, leading to the persistent release of cortisol, which has broader implications for physical and mental health. Over time, unrelenting cortisol production can lead to short-term memory loss and concentration challenges. Similarly to its role in immune function, healthy cortisol levels actually improve memory. It’s only when cortisol production is too high that the adverse effects occur. The immune system also suffers, as elevated cortisol levels interfere with its ability to fight infections and manage inflammation effectively.
Cortisol and Cellular Aging
Elevated cortisol levels can disrupt digestive function and interfere with sleep patterns. Without proper rest and nutrition to help it recover, your body cannot effectively maintain cellular health. To understand this a little more, let’s talk about how your body ages. Every day, millions of cells in your body die. Those cells are then replaced by new ones. As the years go by, the function of those new cells starts to decline.
Aging is not just one process, but the culmination of many different processes slowing down and becoming less effective. The rate at which this decline occurs is determined by countless factors, including genetics, lifestyle choices, environmental factors, and, yes, stress. As we’ve discussed, chronic anxiety and elevated cortisol levels impact brain function, cardiovascular function, respiratory function, digestive function, and more. As all of these processes lose effectiveness, the results will be cellular aging.
What Can You Do?
If you experience prolonged anxiety, hope is not lost. The combination of therapy, medication, and self-care practices offers a comprehensive approach that can be effective in managing anxiety symptoms and reducing their negative effects. Therapy is focused on changing thought patterns and developing effective coping mechanisms when stress takes hold. Anxiety medication tackles symptoms at their source, aiming to balance brain chemistry and prevent anxiety symptoms from cropping up. Self-care practices like exercise, healthy eating, and improving sleep hygiene also make a huge difference for your mental health and cellular aging.
