Most people learn through experience that certain activities will make them dizzy and they learn to avoid them. For example, if reading in a car produces motion sickness, an individual leaves reading materials for after the trip.
Changes to the diet can also cut down on episodes of dizziness in susceptible people. Relaxation techniques can help ward off tension and anxiety that can cause dizziness. These techniques can help minimize or even prevent dizziness for people with chronic diseases. For example, persons with Méniére’s disease may avoid episodes of vertigo by leaving salt, alcohol, and caffeine out of their diets. Reducing blood cholesterol can help diminish arteriosclerosis and indirectly treat dizziness.
Some cases of dizziness cannot be prevented. Acoustic neuromas, for example, are not predictable or preventable. When the underlying cause of dizziness cannot be discovered, it may be difficult to recommend preventive measures. Alternative approaches designed to rebalance the body’s energy flow, such as acupuncture and constitutional homeopathy, may be helpful in cases where the cause of dizziness cannot be pinpointed.
Follow these steps:
- Stop whatever you are doing. Nothing is as important as your health and state of mind.
- Sit down with your head between your legs. This will help the blood flow to your brain.
- Breathe deeply and slowly. Your brain is starving for oxygen so you need to make sure you take in large breaths but do them slowly so you don’t hyperventilate.
- Respond to others with simple nods or shakes of the head if you are not alone. This assures you not only stay alert, but it assists others in knowing what you need.
- Keep a running dialogue with yourself. Even if it’s a fight to stay awake, speaking with yourself does help to a degree. – Stay seated once the worst has passed.
- Lift your head slowly, if you feel any dizziness go back to putting your head between your legs. Repeat until you no longer feel dizzy.
- Get up slowly and carefully. Accept any offers for assistance if you wish, but return to your seated position if you feel another attack coming on.
- Take small sips of water until all symptoms (such as cold sweats, dry mouth, and nausea) have dissipated.
If, for some reason, it would be unsafe to stop and sit down where you are (for example, while crossing the street) just walk slowly with your head down and breathe deeply until you can get to a safe place (such as a sidewalk).
However, if you experience extreme tunnel vision this is a warning sign that you are about to faint. In that case, just stop and breathe deeply until the tunnel vision dissipates as someone who is standing is much less likely to be hit than someone who has fainted.
