Can Stress and Anxiety Cause Palpitations?

Introduction

Heart palpitations are sensations of a rapid, fluttering, or pounding heartbeat. Many people experience them occasionally, and they can be caused by various factors, including stress and anxiety. This lecture will explain how emotional stress affects the heart and when palpitations might indicate a more serious condition.

How Stress and Anxiety Affect the Heart

Stress and anxiety activate the body's "fight or flight" response, which releases stress hormones like adrenaline. These hormones: - Increase heart rate - Cause stronger heart contractions - Lead to an irregular heartbeat

In people prone to anxiety, even a slight rise in heart rate can be perceived as alarming, leading to a cycle where fear of palpitations causes even more stress and worsening symptoms.

When Are Palpitations a Sign of a Serious Problem?

While stress-induced palpitations are usually harmless, they can sometimes indicate an underlying heart condition. Seek medical attention if you experience: - Palpitations lasting several minutes or longer - Dizziness, fainting, or shortness of breath - Chest pain or discomfort - A history of heart disease

Management and Prevention

To reduce stress-induced palpitations, consider: - Practicing relaxation techniques (deep breathing, meditation, yoga) - Avoiding caffeine, nicotine, and alcohol, which can worsen symptoms - Engaging in regular physical activity - Getting enough sleep and maintaining a healthy diet - Seeking professional help if anxiety is severe

Conclusion

Stress and anxiety are common causes of palpitations, but they are usually harmless. However, persistent or severe symptoms should not be ignored, as they may signal an underlying condition. If you are unsure, consulting a doctor is always the best approach.
