What causes passing out with eyes open?

Have you ever seen someone pass out, eyes open and still standing? Or perhaps you’ve experienced it yourself? It can be a shocking and confusing experience to witness. But what exactly causes this phenomenon?

Fainting: A Brief Introduction

Fainting, also known as syncope, is when an individual suddenly loses consciousness. There are many different reasons why people faint, ranging from dehydration to underlying medical conditions such as low blood pressure or heart disease.

Pass the Salt: Dehydration

One common cause of fainting is dehydration. When your body loses too much water or salt, it can lead to a drop in blood pressure and ultimately result in passing out. So drink up! And grab that bag of chips while you’re at it.

Standing Up Too Quickly: Orthostatic Hypotension

Orthostatic hypotension occurs when there’s a sudden decrease in blood pressure due to changes in position – often from sitting or lying down to standing up quickly. This can cause dizziness or lightheadedness which may progress into fainting if not treated properly.

Pro tip: Next time you jump up out of bed because you snoozed your alarm one (ten) too many times… proceed with caution!

Beware the Vasovagal Response

The vasovagal response is another common cause for fainting where the body’s reaction to certain triggers causes blood vessels to dilate thereby dropping overall cardiac output which leads decreased brain oxygenation eventually resulting loss [of]―consciousness

Some examples include:

  • Sight/sound/thought of something disturbing (cue dramatic music)
  • Intense emotions like fear (taps forehead)
  • Sudden pain (cringes involuntarily)

Situational Awkwardness Syndrome (SAS)
Have you ever been so embarrassed that all you could do was stare off into the distance? That glazed-over look in your eyes may be a form of fainting triggered by the vasovagal response. The next time you stumble over your own words in front of your crush, keep this one in mind.

Dry Heaves and Puking: Yes, There’s A Link

Ever felt nauseous or vomited before passing out? You’re not alone! Sometimes dry heaving or vomiting can trigger fainting episodes by activating that pesky vasovagal response we mentioned earlier. So next time you think “oh God I’m about to puke,” just know it could mean something else entirely.

Pro tip: When in doubt, always carry around an extra garbage bag or two…just for those moments.

Medication Side Effects

Certain medications have been known to cause fainting as a side effect. Common culprits include:

  • Blood pressure medication (ironically enough)
  • Anti-anxiety meds (deep breaths)
  • Benzodiazepines (for those unfamiliar with pharmacology: fancy Xanax)

So if you’ve started taking any new medications and experience sudden dizziness or lightheadedness, make sure to speak with your doctor!

Cardiac Chaos: Heart Issues

In some cases, fainting can be attributed to underlying heart conditions such as arrhythmia – where there are abnormal electrical signals within the heart resulting in irregular heartbeats (the technical term is “chaotic heartbeat”), which stutter oxygenated blood flow to brain ultimately leading unconsciousness .

Side note: Did someone say Chocolate??!! Well research indicates that chocolate intake increases risk factors like getting flunked out by fluttery dysfunctional cardiac rhythms ,leading to deadly pass outs but hey … do what makes you happy 😉

Cue Dramatic Music Again: Neurological Causes

Less commonly, neurological factors such as seizures head trauma stroke can lead to fainting. In these cases, immediate medical attention is necessary.

So there we have it folks! A brief rundown of some of the reasons why someone may pass out with their eyes open (cue Avengers Endgame “whatever it takes” meme). If you or anyone you know experiences passing out episodes regularly, make sure to speak with a medical professional ASAP!

Our recommendation: always keep snacks & water close by…just in case 😉

Stay safe and keep on thriving!
