What causes passing out while stretching?

Vasovagal syncope (VVS), also known as vasovagal reaction, is a common condition that causes fainting or near fainting. It's triggered by certain triggers, such as the sight of blood, extreme emotional distress, or standing for a long time.

_Here's what happens during VVS:_

- When you stand up, gravity pulls blood down to your legs, which can cause your blood pressure to drop. This drop in blood pressure can make your heart rate slow down and cause you to feel lightheaded or dizzy.

- A sudden drop in blood pressure can also lead to a temporary loss of consciousness. This is what happens when you faint or "pass out."

Risk Factors for VVS:

- Age: Young adults and elderly people are more likely to experience VVS.

- Gender: Women are more likely to experience VVS than men.

- Medical conditions: Certain medical conditions, such as heart disease, diabetes, and dehydration, can increase your risk of VVS.

- Medications: Some medications, such as blood pressure medications and antidepressants, can also increase your risk of VVS.

_Triggers for VVS:_

- _Physical triggers:_ Standing for a long time, overheating, dehydration, and exercising vigorously.

- _Emotional triggers:_ Stress, anxiety, fear, and anger.

- _Medical triggers_: Seeing blood, having a blood test or injection, or having surgery.

_Symptoms of VVS:_

- Lightheadedness or dizziness

- Blurred vision

- Nausea

Here's what you can do if you feel like you're about to faint:

- Stay relaxed.

- If your symptoms do not improve, call your doctor.
