Anxiety causes a faster heartbeat. However, it is so far unclear whether the reverse holds true - that a faster heartbeat causes anxiety.

The theory of the physiology of emotions, proposed more than a century ago, suggests that emotions may come from the body as well as from the brain.

Although the topic has been widely discussed, until now, researchers have not had the experimental means to test this theory.

Anxiety can be a debilitating condition that affects millions of people around the world. One pervasive symptom of anxiety is a racing heart, known as tachycardia. In a normal situation, the heart rate quickens as a natural response – known as the “fight-or-flight” response – to a stressful situation. But for people with anxiety, this response can become excessive and lead to further distress.

So what causes tachycardia as a result of anxiety? It is thought that this is caused by the release of stress hormones into the blood stream, in particular adrenaline and cortisol, which cause the heart to beat faster. This can be accompanied by chest tightness, palpitations, and difficulty breathing.

The good news is that, while tachycardia is often a frightening symptom of anxiety, it is rarely a serious problem. There are a number of measures which can be taken to help manage an increased heart rate as a result of anxiety.

First, it is important to try and calm yourself down. Simple relaxation techniques such as deep breathing, yoga and meditation can help to reduce the physical symptoms of anxiety, including tachycardia. Additionally, it is important to avoid caffeine and other stimulants which can worsen anxiety symptoms.

Regular exercise can also help to reduce anxiety and tachycardia in the long term, as it boosts serotonin levels in the brain and helps to combat stress and fatigue. It is important to consult your doctor if you have any concerns regarding tachycardia and anxiety. They may suggest cognitive behavioral therapy or medication to help manage the symptoms.

In conclusion, a racing heart is a common symptom of anxiety, but it is manageable and rarely a serious problem. With the right support and steps taken to reduce anxiety, you can start to feel better and regain control of your life.
