Recommendations to prevent fainting

• April 20, 2024

Some people get dizzy just before they faint. They may also experience changes in vision (such as "tunnel vision"), tachycardia (acceleration of heart rate), sweating, and nausea. Another symptom before fainting, in certain people, is vomiting.

If you think you are about to faint, maybe you can prevent it by following these steps:

• If possible, stretch yourself on a horizontal surface. This can help you avoid fainting because it favors cerebral blood flow. When you feel better, make sure you wake up little by little; first sit down and stay several minutes in that position and after a while stand up.
• Sit and lower your head, placing it between your legs. You will also favor the cerebral blood supply, although it is not as recommendable as stretching. When you feel better, sit in a more upright posture and, after a while, stand up.
• Do not get dehydrated Drink enough, especially when your body loses a lot of water due to sweat and / or heat.
• Keep the blood circulating. If you have to stand or sit for a long time, periodically tense the muscles of the legs or cross them to promote blood flow so that the blood can reach your heart and brain. Try to avoid environments that are too hot, crowded or poorly ventilated.
