Can anxiety be life-threatening? The answer isn’t simple. Studies show that anxiety disorders have a small link to a higher risk of death overall, but it depends on the type of anxiety, your health, and if depression is a factor (links to these studies are included throughout).
This is a topic close to home for me. I’ve lived with a variety of anxiety disorders, and have recently had other health issues which, based on the facts I found across numerous studies, may be related. Thus, making this all very important to me, as it might be to you.
In this article, I’ll walk through eight facts about anxiety and mortality, from what the studies say to how different types of anxiety may affect your health.

1. A slightly higher risk of death

A study found in 2023 found “an adjusted HR of 1.05 (95% CI 1.03 − 1.07)” for mortality in patients diagnosed with anxiety. HR stands for hazard ratios.
A separate study in 2017 had a similar finding, “the overall pooled estimate of HR for all-cause mortality among people with anxiety disorders or clinically significant anxiety was 1.09 (95% CI: 1.01–1.16).”
Both of these reports say that the overall impact of anxiety on mortality is modest. Which is a relief for anyone who suffers from anxiety disorders, including me.
However, many of the following facts showcase how different anxiety disorders impact mortality. Some of the facts may be surprising.

2. Differences across anxiety disorder types

The impact of anxiety on mortality isn’t the same for every disorder type. A study found that “phobic anxieties showed no significant association with mortality, whereas stress-related conditions appeared to reduce mortality risk only after full adjustment with a HR of 0.89 (95% CI 0.80 − 0.98)” (HR stands for hazard ratios).
While I haven’t experienced phobias, I’ve dealt with panic disorder, social anxiety disorder (SAD), and generalized anxiety disorder (GAD) for a long time. It’s interesting to see that some forms of anxiety might even lower risk.
3. Chronic Anxiety and Premature Death Risk

Chronic anxiety significantly increases the risk of premature death. A study found that “for those who experienced affective problems 1, 2, and 3-4 times, the premature mortality rates increased by 76%, 87%, and 134% respectively, compared to those who never had affective problems.”
In simpler terms, the more episodes of anxiety or depression someone goes through, the higher their risk of dying early. These repeated struggles can build up over time and take a serious toll on the body. I’ve had periods of anxiety that felt unending, and looking at these numbers, it’s clear how important it is to find ways to manage anxiety before it becomes a long-term cycle.

4. Anxiety and Long-Term Mortality in Cardiac Arrest Survivors

Anxiety disorders are linked to a higher risk of long-term death in people who survive out-of-hospital cardiac arrest (OHCA). A study found that “patients diagnosed with depression or anxiety had an approximately 40% higher long-term mortality rate than those without such psychiatric disorders.”
This fact hits close to home for me after my own recent heart-related medical issues. It is a reminder that anxiety does not just affect your mind. It can make it harder for your body to recover after serious health events.
5. Anxiety and Its Impact on Heart Health

“Anxiety has profound effects on both mind and body. While the risk of premature death associated with anxiety may seem small, it is crucial to recognize how chronic anxiety, especially when combined with depression or heart conditions, can significantly impact one’s overall health. Studies consistently show that anxiety disorders can strain the cardiovascular system, interfere with recovery from serious health events like cardiac arrest, and potentially increase the risk of mortality if left untreated. It is not just the emotional toll that matters, but the physical toll as well. life. If you or someone you know is struggling, it’s vital to seek professional help as soon as possible.” – Dr. M. Ahmed, University Hospitals of North Midlands
Anxiety can strain the heart and potentially lead to serious cardiac issues. According to research, “anxiety may have an association with the following heart disorders and cardiac risk factors: rapid heart rate (tachycardia) – in serious cases, can interfere with normal heart function and increase the risk of sudden cardiac arrest.”
As mentioned above, any fact linking anxiety disorders and heart health hits home for me. I know how anxiety can send my heart racing, amplified further by panic attacks. Based on this fact, taking steps to manage anxiety could play a role in protecting your heart’s health.

6. Anxiety and Cardiovascular Mortality

The relationship between anxiety and cardiovascular mortality is not simple. A 2008 study found “a decreased incidence of cardiovascular-related death among people of all ages who had panic attacks or panic disorder (PD).” This seems surprising, especially since anxiety often feels like it puts so much strain on the heart.
I have experienced panic attacks, and they can feel terrifying as if my heart is under extreme pressure. Knowing that panic attacks might not always lead to higher heart-related death rates is somewhat reassuring. However, it shows how complex the question can you die from anxiety disorder is.
7. Severe Anxiety and Increased Mortality Risk

Severe anxiety symptoms can significantly increase the risk of death. A study found that “people who reported severe problems of nervousness, uneasiness, and anxiety suffered from about twofold to threefold increased risks of death.” This is a terrifying reminder of how serious anxiety can be if it goes unchecked.
I know what it feels like to be overwhelmed by anxiety, where the uneasiness doesn’t go away and every day feels like a battle. Reading this makes it clear how important it is to address anxiety early, whether through therapy, medication, or lifestyle changes. Sadly, I left it a long time, if you’re suffering, don’t make that mistake.

8. The Role of Depression in Anxiety’s Effect on Mortality

Anxiety’s impact on mortality might be partly explained by depression. A study found “there was no evidence of an association between anxiety and all-cause mortality in studies adjusting for depression (HR: 1.01; 95% CI: 0.96–1.06).” This suggests that in many cases, it could be depression, rather than anxiety itself, driving the increased mortality risk.
For me, this is a powerful reminder of how closely mental health conditions can be linked. While I’ve struggled with anxiety, there have been moments where it crossed into feelings of hopelessness and low mood. This study shows the importance of addressing mental health before it impacts health.
