Orthostatic hypotension
Hypotension, also known as low blood pressure, is one of the causes of dizziness, particularly when going from lying down to sitting or standing. “When you get up too quickly from a sitting or lying position and your blood doesn’t travel as quickly up to your head, you can experience a ‘head rush’ feeling,” explains Sherry Ross, MD, ob-gyn and women’s health expert at Providence Saint John’s Health Center in Santa Monica, California. To prevent this type of dizziness, take your time changing body positions. Also, talk to your doctor about possible issues with your circulation.
Dehydration
Being even slightly dehydrated is another one of the common causes of dizziness, as it slows blood circulation. A lack of proper hydration can cause blood pressure to drop quickly which, in turn, causes dizziness. Here are 9 clear signs you’re about to faint.
Caffeine overdose
Drinking more than the recommended daily amount of caffeine—which is 400 mg—can lead to dizziness. Caffeine is a stimulant, and stimulants restrict blood flow to the brain. Blood not flowing properly to the brain could be a cause of dizziness.
