Here’s what happens to your body when you pass out in formation
There you are, marching in a perfectly structured formation when you hear the command to halt. Along with the rest of your platoon, you stop on a dime. The whole unit looks well-disciplined as each service member stands up straight, assuming the position of attention.
You stand proudly in front of all your friends and family with your chest out and eyes forward. Then, suddenly, something weird begins to happen. You start to feel weak and your legs give out. You fall directly to the ground like a sack of potatoes.

The next thing you know, your eyes open, you see the medic, and you realize you just passed the f*ck out in front of everyone. How freakin' embarrassing, right?
Well, you just experienced what medical professionals call "syncope," which is the loss of consciousness due to decreased blood pressure. During bouts of hypotension (lowered blood pressure), our brains aren't getting the oxygen or glucose they need, so it shuts down as it tries to recover.
So, why would someone pass out in formation? Well, it could be one of several happenings within the body.
Fainting can be a reaction to intense stress triggers, like seeing something crazy, being exposed to heat, or standing for long periods of time. This is called a vasovagal syncope, and it occurs when the part of your brain that governs heart rate malfunctions in response to an external trigger. So, if you're standing completely still in the heat for long enough and you start to feel lightheaded, this might be what's happening behind the scenes.

A sudden change of position may also be to blame. Our blood vessels change width to make sure every part of our body is getting the supply it needs. Sometimes, however, our vessels can't keep up with the rapid changes to the body's position. If you're laying or sitting down, our heart rates are low. If we then quickly stand, our hearts have to speed themselves up in mere moments — sending blood rushing to the brain. This can cause momentary lightheadedness — and, in extreme cases, you might pass out.
Hunger may also be a factor in why your body shuts down. Your brain needs glucose to function — and glucose comes from eating. So, remember to snack before you take on those high-impact activities you like to do on the weekends.
Lastly, not properly hydrating is also to blame. Without enough water, your blood becomes thicker than usual. This causes your heart to work overtime to supply your brain with the oxygen and glucose it continually needs to sustain itself.
In general, some people are prone to passing out due to poor circulation while others may sometimes experience episodes of vasovagal syncopes. Unless injured by the fall, typically, no treatment is required. Most cases of syncope only last a few seconds, but if this event begins to happen more frequently, that person might have a cardiac condition.

So, if you find yourself often passing out often, book an appointment with your doctor soon.
