Because when you are sitting the blood is circulating slower in your body, when you stand up suddenly or quickly the blood gets pulled down. Then your head and brain are temporarily not given enough oxygen so in a result you feel dizzy and lightheaded.

What should a blood doner do if there is lightheadedness and dizziness the day after donating?

Lie down on the floor and raise your legs up high for a few mins, for example 2mins. When you stop felling dizzy/lightheaded slowly stand up from the floor. If you are still felling dizzy or lightheaded lie down again with legs raised, but for a longer period. If it is a problem that doesn't seem to go away, you must ask someone to call for an ambulance for you or arrange transport to the nearest hospital.


Why do you feel lightheaded?

A. Being lightheaded or dizzy is a symptom that needs to be diagnosed by a physician. It can be simple or very complex. If this is a constant symptom, a trip to the doctor is in order. If you stand up quickly and get lightheaded, this may be due to low blood pressure or something called orthostatic hypotension. If you are standing and become lightheaded, you may need to sit and lower your head to a position lower than your heart...between your knees. Side effects of certain drugs can be lightheaded and dizzy. Being dehydrated can also cause you to be lightheaded. Your doctor will want to know when you become lightheaded (during certain activities, times of day, etc) and how long you have been experiencing the problem. B. What it feels like: You may get it when you stand up quickly. Basically you feel faint and you might feel a bit sick, hearing goes a bit weird-either fuzzy or everything silent, your eyes sometimes stop working well- fuzzy or tunnel vision, but generally it's just a weird feeling in your head.

When you sleep a lot and get up suddenly or if you sit on the couch for an hour or two and suddenly get up why do you black out for 2 seconds?

If you suddenly get up, the blood drains from your head and you will feel dizzy (happens to me). The best thing to do is gradually get up instead of suddenly, then the circulation has more time to adjust to the change.
