The point of elevating the feet and lowering the head is not to raise blood pressure, but to use gravity to cause an increased flow of blood to the brain.
Your heart pumps blood to all organs in your body. when you stand upright blood will be pumped to your feet with much less effort than standing on your head. When you are under normal gravitational force, even though gravity has an effect on blood flow, your blood circulation is totally controlled by your heart. So when you stand on your head blood will also be pumped to your feet.
There is more blood in the head than the feet.
The same as it does when you are standing on your feet. Your heart pumps and forces the blood through your body.
No you cant. Your blood will run to your head and you will injure yourself
When you run for a half hour, the repeated impact and pressure on your feet can compress the nerves and blood vessels, reducing blood flow to your feet. This lack of blood flow can cause a tingling sensation or numbness, making your feet feel like they are asleep. It's important to ensure you have properly fitting shoes and take breaks to stretch and allow blood flow to return to your feet while running.
Actually, what you are probably referring to is the first aid advice for helping a person who has fainted by raising THEIR feet higher than THEIR head to allow more blood to get to their brain.
yes, in fact it does because when you exercise your heart beat gets faster, well the same thing happens here so then the blood get "super pumped" throughout the body. (including your feet)
Head over Feet was created in 1995.

Your brain needs a constant amount of blood pumped up to it in order for it to function properly. (If you have a poor blood circulation, you should consult your local doctor). The blood pumped by the heart is sent to different parts of the body through blood vessels called Arteries. One of it's destinations is to your brain (carries oxygen, glucose etc to the cells). In order for the blood to be pumped up to your head the blood needs to be under pressure. When the blood is under pressure it pumps further, which is what is needed for the blood to be pumped up to your brain. The blood does not need to be under pressure when it travels to your feet since it can work together with gravity to reach it. But when the heart wants to pump blood up to your brain, it has to work against gravity which is why pressure is needed. Branchiocauras's have necks that can measure up to 5-8 meters long. The blood pumped by the heart needs to be under a tremendous amount of pressure so that enough blood reaches your brain.
