In brief: Ortho static change

Blood pooling in your leg causes transient decrease blood flow in the brain (highest point of your body) , it take seconds for heart to pump faster and arteries to constrict in order to send blood to brain.
Hydrate well, get up slowly. See doctor if repetitive, severe or disabling.
