In case of fainting, what should you do?

Laying the person down and elevating their legs, if no injuries are suspected, is an appropriate response to fainting. This position helps improve blood flow to the brain, which is important since fainting can be caused by reduced blood flow and oxygen to the brain. By placing them in a supine position and elevating their legs, you can encourage more blood to return to the heart and circulate to the brain, potentially preventing loss of consciousness or speeding up recovery.

Other options do not appropriately address the situation: shaking someone could cause injury or distress; offering water may not be advisable as the person may not be alert enough to swallow safely; and leaving them sitting up could lead to further complications, such as another fainting episode. The main goal is ensuring the person is in a safe position that supports recovery and minimizes risk.
