While it's more common for heart rate to increase during periods of anxiety or stress due to the body's "fight or flight" response, some people may experience a decrease in heart rate. This could be related to a variety of factors. Here are a few possibilities:
Vagal Response: The vagus nerve, part of the body's parasympathetic nervous system, can cause a decrease in heart rate as a response to stress or anxiety. This is known as the "rest and digest" response, which is the opposite of the "fight or flight" response triggered by the sympathetic nervous system.
Individual Variations: People's bodies react to stress and anxiety in different ways. Some people may have a lower heart rate due to individual physiological differences.
Use of Medications or Substances: Certain medications, particularly beta-blockers, are known to decrease heart rate. Some substances, including alcohol and certain recreational drugs, can also lower heart rate.
Mind-Body Techniques: Some individuals may unconsciously employ mind-body relaxation techniques during anxiety episodes, which can lower heart rate.
Orthostatic Hypotension: Anxiety and stress can cause temporary drops in blood pressure, leading to a decreased heart rate. This usually happens when you stand up from sitting or lying down.
However, a decrease in heart rate during periods of anxiety is less common and could potentially be a symptom of an underlying health issue. It's important to discuss this with a healthcare professional who can evaluate your symptoms and determine if further tests or treatments are needed.
