Over Christmas, I met up with some cousins I hadn't seen since I was young. I knew we shared the thin blond hair that runs rampant in our family, but I found out we had another similarity--we get dizzy whenever we stand up. I guess it's not an uncommon thing, but I've never met someone who has this as often as I do.

Why do we get dizzy? It's because the blood rushes from our head too fast when we get up. In my case, it's down to a family history of low blood pressure, but there are lots of causes out there, including:

• Blood pressure medications
• An irregular heartbeat
• Dehydration
• Prolonged bed rest.

If you're feeling dizzy too often, try drinking more water. If that still doesn't help? See your doctor and get your blood pressure checked.
