It's important to consult with a healthcare provider for a proper evaluation and diagnosis.
Feeling shortness of breath, a fast heart rate, and experiencing panic or anxiety during a hot bath could be related to a condition called vasovagal syncope or vasovagal response. Vasovagal syncope is a common fainting response that can be triggered by various factors, including exposure to heat, especially in a hot bath or sauna.
During a hot bath, the body's temperature rises, leading to vasodilation (expansion of blood vessels) in an attempt to cool down. This can cause blood to pool in the lower parts of the body, leading to decreased blood flow and a temporary drop in blood pressure. In response to this drop in blood pressure, the body activates the vasovagal response, which can cause symptoms like dizziness, rapid heart rate, shortness of breath, and even fainting.
Several factors can influence the intensity of this response, including individual susceptibility, the duration of exposure to heat, hydration level, and other underlying health conditions.
However, it's essential to consider that there might be other potential reasons for your symptoms. Panic attacks or anxiety disorders can also lead to similar physical sensations, such as shortness of breath and a fast heart rate. If you have a history of anxiety or panic attacks, the heat from the hot bath might trigger or exacerbate these symptoms.
To get a proper diagnosis and appropriate advice, I strongly recommend discussing your symptoms with a healthcare professional. They can assess your medical history, conduct a physical examination, and perform any necessary tests to determine the underlying cause of your discomfort during hot baths and provide you with the best guidance and treatment options.
