Dizzy when I bend my head down to read or rest my back on a chair?

BPPV. You may have a condition known as Benign Paroxysmal Positional Vertigo. You're a bit young overall but it's not uncommon in young women especially if they do things such as low impact aerobics, contact sports, etc. Easy to understand and Easy to Treat.
