Fainting is due to a temporary insufficient supply of blood reaching the brain as a result of one or more of the following conditions:
- fatigue, fright, fear, emotion, mental shock;
- lack of food, lack of fluids, heat exhaustion;
- injury, pain, loss of blood;
- lack of fresh air.
If a person looks pale and starts to sway about, prevent him from fainting by making him sit down with his legs apart and his head well down between his knees, or lay him flat on his back and raise his legs. If you are sure that he can swallow, give him a little water; this will help to revive him.
