This Is Why You Don’t Faint When You Stand Up

Have you ever wondered why you don’t faint when you stand up? No? Well tough, you’re going to find out anyway.

A study in the journal Science, led by Scripps Research, has looked into a medical phenomenon called the baroreceptor reflex. This is the idea that neurons are able to respond rapidly to keep the blood pressure in your body steady. Exactly how the baroreceptor reflex works has been a mystery for nearly 100 years, though.

“For example, when you stand up, your blood pressure normally drops – rapidly,” a statement from Scripps noted. “Yet you don’t faint thanks to baroreceptors, which tell your heart rate to increase and push more blood to your brain.”
