Why does our head fall down first when we faint?
Fainting is called hypoxia.
Brain function is particularly dependent on oxygen.
Our brain uses, more than 25 percent of the body’s oxygen supply, (at rest it is about 20%).
If there is not enough oxygen supply to the brain, we faint.
In such a case, the head first tilts towards the ground, in an attempt to immediately take in oxygen.
This is because, more oxygen is concentrated closer to the Earth, due to the effect of gravity. If hypoxia persists for more than two minutes, permanent brain damage is possible.
