Everything was going well You were tying your laces You stood up the moment you were done Wait a second You were feeling dizzy and felt a blackout But felt normal in a few seconds? What really happened? I’ll tell you what happened Your blood pressure got low Blood pressure indicates the speed at which the blood flows in the arteries And when you go to get your blood pressure measured the reading tells you just that how fast is the blood flowing in your arteries During the day, our blood pressure keeps fluctuating Low when we are sleeping but high when we are running Blood pressure being too high or too low both are harmful for us But everyone’s blood pressure can be different as well Like blood pressure that is normal for me could be high for you and the same pressure could be low for someone else like it has been seen that people who smoke have high blood pressure High blood pressure is called Hypertension which causes harm to our heart and arteries On the other hand low blood pressure is called Hypotension which can cause dizziness or vertigo There are several reasons for low blood pressure like during preganancy deficiency of blood, water etc. But here, the low blood pressure we are talking about happens when we stand up all of a sudden and it is called Orthostatic or Postural Hypotension when you are sitting the blood is flowing well through out your body but the moment you suddenly stand up the pull of gravity keeps the blood near the feet in this situation, our heart beat increases our veins contract, so that blood reaches the upper body too specially to our brain but all of this takes a couple of seconds and for those seconds, our heads spin Feeling of dizziness is our brain telling us that Dude! I need oxygen. If you are standing up too quickly, then you might faint as well but most people feel light headed for just a few seconds and there is nothing to worry about but if you want to avoid all of this then you have to stand up without hurrying That is all!
