Fainting can be avoided by learning to take notice of early warning signs such as light-headedness, dizziness, nausea, and doing something about it.
Lie down immediately; if possible elevate your legs
If your circumstances make this difficult:
Cross your legs while standing or rock up and down on your toes
Clench buttocks and abdominal muscles
Clench your fists
The risk of fainting can also be minimised by:
Come up from lying to standing slowly, sitting for a while first.
Avoid prolonged standing (* or sitting) –*fidgeting is the key.
*Avoid having your hands over your head for a prolonged time.
*Prolonged sitting can cause symptoms in some people. Elevating legs can be helpful.
*Currently no available medical evidence. Based on patient or expert experience and opinion.
