Most kids who faint have symptoms just beforehand. These may include:
- Dizziness
- Feeling lightheaded
- Skin is cold and sweaty (sometimes referred to as breaking out in a cold sweat)
Preventing a fainting spell
If your child is prone to fainting spells, there are some things you can do to help them head off an episode.
First, know the symptoms. Some people feel dizzy immediately before they faint. They may also notice changes in vision (such as tunnel vision), a faster heartbeat, sweating and nausea. Someone who is about to faint may even throw up. If your child experiences any of these symptoms, he or she can try the following:
- If possible, lie down. This can help prevent a fainting episode as it allows blood to circulate to the brain. Just be sure to have your child stand up again slowly when he or she feels better – start by moving to a sitting position for several minutes first, then to standing.
- Sit down with the head lowered forward between the knees. This will also help blood circulate to the brain, although it's not as good as lying down. When your feels better, have them move slowly into an upright seated position, then stand.
- Don't get dehydrated. It is very important for a child, teen or young adult to drink enough fluids, especially if his or her body is losing more water due to sweating or being in a hot environment. They should also drink enough fluids before, during and after sports and exercise.
- Keep blood circulating. If your child has any activity that requires standing or sitting for a long time, teach them to periodically tense their leg muscles or cross their legs to help improve blood return to the heart and brain. Whenever possible, your child should avoid overheated, cramped or stuffy environments.
