Typical symptoms of feeling faint include feeling lightheaded, dizzy, weak, nauseated and sweaty, the American Academy of Family Physicians. Fainting can be triggered by standing up too quickly, working or playing too hard in hot weather, breathing quickly, becoming very upset or by certain medications used to treat high blood pressure.
The academy offers these suggestions if you feel like you are going to faint:
- Lie down.
- If you can’t lie down, sit and bend forward with your head between your knees, which will encourage blood flow to the brain.
- Do not try to stand until you feel better. When you do stand, do so slowly.
