You know the feeling dizzy, light headed, tunnel vision, and clammy (cool, pale, and sweat) you're about to faint. Have you ever wondered if you could prevent fainting before it happens? Here are a few tips to help prevent it if it does happen to you.

[edit] Steps

Remove yourself from the situation, think of something else, and let someone (even if it’s a stranger) know that you are feeling faint.
Know that if you still feel dizzy, light headed, or like fainting take a couple deep breaths to try and calm your nerves.
Put you head between your legs or lay down on your back with your legs slightly elevated. Remember to keep taking long breaths.
Drink something with calories and sugar (soda, juice etc.) or if you don’t have access to these things, drink water.
Learn that if you do end up fainting try to wait 15 – 20 minutes before trying to get up and returning to normal activities.

[edit] Tips

Fainting is commonly brought on by lack of blood flow to the brain.
It is mostly caused by standing up to fast, medications, or extreme emotions.
You should seek medical assistance if you have constant fainting spells.

[edit] Warnings

If you are driving when you start to feel faint pull over to a safe place.
If you have other symptoms – headache, back pain, chest pain, shortness of breath, abdominal pain, weakness, or loss of function seek medical help immediately.
Many people have been seriously injured fainting in the bathroom late at night. Probable causes are low blood pressure and for men the shutting down of the vagus nerve while urinating. Have a nightlight in bathroom, take it slow when getting out of bed and sit while using the toliet.
