The things and events that cause stress are called stressors. And anything from a project deadline, grief, to unpaid bills can be a stressor.

When the body senses stressors or a need for adjustment, it releases chemical messengers that cause body changes. These modifications disrupt the body’s normal and relaxed state and stimulate every organ to work faster, better, and with more force. With high-functioning organs, it will lead to better blood flow, stronger muscular endurance, and rapid breathing. And these changes do not necessarily indicate awful conditions. During danger and emergency, the body undergoes the same alteration and makes you run faster and lift heavier weights. Indeed, you will need all these boosts to fight or flee the danger.

According to the duration of the body reaction, stress could last for a few moments or long years. Here are the types of stress you will often encounter:

Chronic Stress

This type is where the harmful effects of stress could take a toll on your body. Aside from vasovagal syncope, chronic stress could also increase your risk for stroke and suicide. With the constant presence of stress, afflicted people fail to notice the presence of stressors anymore.

How Can Stress Cause Blackouts

Syncope is a medical term that refers to passing out. There could be many reasons why people lose consciousness. And while there are several syncope types, vasovagal syncope is the one so often how can stress cause vasovagal syncopeassociated with stress. When you lose consciousness due to a distressing stimulant or terrifying trigger, it could lead to vasovagal syncope. It typically happens when the blood flow suddenly drops. When the brain senses the presence of an intense trigger, it could go haywire. And like in stress, it sends chemical signals to other organs such as the heart and vessels. With this, heart rate slows, while vessels in the feet widen. These changes will cause the blood to pool at the bottom. Hence, blood pressure in the body drops.

As you know, organs get their nutrients and oxygen from the blood. But with vasovagal syncope, the blood flow becomes insufficient in supplying these provisions. Without these supplies, the brain will shut down, causing the person to lose consciousness or faint. This interplay between the heart and brain also paved for the term cardio-neurogenic syncope. Some common triggers of vasovagal syncope other than stress include orthostatic hypotension, standing for long hours, and bodily injury. And although these blackouts are associated with physical threats and horrific situations, thoughts and emotions could also play significant roles. In this case, fainting is called psychogenic syncope. After all, a stressor could be anything from physical form to memory.


Diagnosing Psychogenic Blackout

Dizziness and fainting happen due to numerous reasons. And when it comes to psychogenic blackouts, the diagnosis could be difficult. Hence, it is important to seek medical intervention right away when signs of vasovagal syncope appear. And although these blackouts could be like the regular dizziness or fainting, it has signs that are different from others. These signs include jerking movements, tightly closed eyes, and a slow, weak pulse. And compared to fainting due to fear and phobia, a psychogenic blackout lasts longer and happens more often. Noting these symptoms will help the physician to diagnose vasovagal blackouts. And even if you cannot note these points on your own, asking someone to look over you will help. Besides, fainting is easy to anticipate as it presents as nausea or lightheadedness at first. Measurement of the cardiac electrical signals, blood tests, and anxiety level evaluation also helps physicians diagnose vasovagal syncope.


Treating Vasovagal Syncope

ways to prevent stressSince common stressors and anxiety are the usual causes of vasovagal syncope, treatment and prevention are possible. The only key element in preventing blackouts from occurring is knowing the cause. Staying away from your stressors will also keep you away from blackout episodes. Other than avoiding your triggers, you could also opt for the following:


Moderate exercise

Regular physical activity has been shown to improve stress and anxiety. It will also condition the heart to pump blood effectively during stressful situations.

Avoiding medicines that lower blood pressure

Since the drop in pressure causes you to lose consciousness, taking drugs to lower blood pressure will do you no good. You should seek medical advice first before taking or stopping medications.

Drinking plenty of fluids

By regulating water intake, you could increase blood volume. Also, as alcohol is associated with fainting and dehydration, it is best to avoid it.

Opt for a high salt diet

Since salt plays a significant role in fluid retention in the body, it will prevent the pressure drop.

Breathing exercises

The rise and fall of the diaphragm often relieve stress and anxiety. It will stimulate relaxation and thus halt the occurrence of stress.
