Dehydration is one of the most common reasons why people are dizzy when they wake up. This makes your blood pressure drop, resulting in insufficient delivery of oxygenated blood to the brain. This can make you feel dizzy when you are lying down, and the dizziness will worsen when you go from lying down to standing up. A common factor in dehydration-related dizziness in the morning is alcohol. If you woke up dizzy and nauseous or in a room that was spinning after a night of imbibing, alcohol is a likely culprit.
In order to maintain normal function, the brain depends on a sugar called glucose for energy. When you eat, glucose is transported from your digestive system to your bloodstream and delivered to the brain. Low blood glucose is also called low blood sugar or hypoglycemia. Diabetes is a condition that affects blood glucose sugar levels. People with diabetes are missing an enzyme that allows glucose to get into the bloodstream, so diabetics have an increased risk for low blood sugar in the morning, which can lead to dizziness and fainting.
Anything that interferes with your breathing will reduce the amount of oxygen that gets to your brain, leaving you feeling dizzy or woozy. Even having a common cold could interfere with normal breathing while you sleep.
If your morning dizziness sets in when you first sit up or get out of bed, you may be experiencing orthostatic or postural hypotension. This is a condition that is caused by inadequate blood flow to the brain and occurs when people get up too quickly after they have been sitting or lying down.
Dizziness or lightheadedness related to orthostatic hypotension lasts for just a second or two, so if your dizziness is persistent, there is probably something else contributing to it. Some medications are known to cause dizziness, and you may wake up in the middle of the night or in the morning feeling lightheaded or faint. Blood pressure medications like ACE inhibitors, beta-blockers, and calcium-channel blockers can all cause dizziness. In addition, drug interactions may leave you feeling dizzy.
When we move, crystals in the inner ear activate tiny hair cells that send information about our movements to the brain. Age-related degeneration or head trauma can cause these crystals to become detached, and they activate hair cells at inappropriate times. If you regularly experience vertigo when waking up, you may have BPPV. People with BPPV often get vertigo when they roll over in bed or turn their head.
BPPV can also affect just one ear, which would cause dizziness only when you turn or roll to one side. BPPV-related vertigo lasts for seconds, and BPPV can also cause lightheadedness, nausea and vomiting, nystagmus rapid, involuntary eye movements , and fainting.
In most cases, occasionally waking up feeling dizzy is not a serious cause for concern. However, if you are regularly experiencing dizziness or vertigo when you wake up, it is recommended that you make an appointment with your doctor.
For many people, drinking plenty of water, eating a healthy diet, and making sure to get some exercise to promote blood flow are sufficient to prevent dizziness.

Other signs of dehydration can include:. Low blood pressure , or hypotension , can cause dizziness in some people. Blood pressure can also suddenly fall when a person changes from a lying or sitting position to a standing position, for example, when they get out of bed in the morning. This sudden drop in blood pressure is called postural or orthostatic hypotension. Prolonged bed rest and certain medications, such as beta-blockers , can also cause low blood pressure.
For people who experience postural hypotension, standing up or getting out of bed slowly and gradually can help prevent dizziness or fainting. Wearing compression stockings during the day may also help some people. If a medication is causing low blood pressure, a doctor may recommend changing the dosage or switching to another drug.
