Why Do You Feel Dizzy When You Wake Up?

You wake up, stretch, and swing your legs over the edge of the bed, ready to start the day. But as you sit up, the room begins to spin around you, leaving you grasping for balance and wondering what's happening.

For many, dizziness in the morning is an unpleasant intrusion—an unexpected issue in an otherwise normal start to the day. Whether it's just a brief sense of lightheadedness or a more prolonged sensation of vertigo, waking up dizzy might disrupt your plans and leave you rushing to get back your bearings.

But why does it happen? What causes this unsettling feeling that can make getting up a dizzying experience? Could it be related to inner ear issues or changes in blood pressure? The causes of morning dizziness are diverse and puzzling.

Here are some common causes of waking up dizzy and what you can do about them:

Inner Ear Problems

  • Benign Paroxysmal Positional Vertigo (BPPV): BPPV is a common inner ear disorder characterized by brief episodes of vertigo triggered by changes in head position. It occurs when calcium crystals in the inner ear become dislodged and float into the semicircular canals, disrupting the normal flow of fluid that helps maintain balance. It can lead to a spinning sensation, especially when moving the head, such as when rolling over in bed or getting up from lying down. Treatment for BPPV often involves maneuvers to reposition the crystals and alleviate symptoms.
  • Meniere's Disease: Meniere's disease is a chronic inner ear condition that causes episodes of vertigo, hearing loss, tinnitus (ringing in the ears), and a feeling of fullness or pressure in the ear. It is thought to be related to an abnormal buildup of fluid in the inner ear. Treatment may include dietary changes, medications to reduce fluid retention, and in severe cases, surgery to relieve pressure in the inner ear.

Low Blood Pressure/Orthostatic Hypotension

Orthostatic hypotension is a sudden drop in blood pressure that occurs when you stand up from a sitting or lying position. This blood pressure drop can cause lightheadedness, dizziness, and even fainting. Factors that can contribute to orthostatic hypotension include dehydration, prolonged bed rest, certain medications, and conditions such as diabetes or Parkinson's disease. Treatment may involve increasing fluid and salt intake, wearing compression stockings, and adjusting medications.


Dehydration occurs when your body loses more fluid than you take in, leading to an imbalance in electrolytes and dehydration. Dehydration symptoms include thirst, a dry mouth, dark urine, and dizziness. Overnight, your body loses fluid through breathing and sweating, so it's essential to rehydrate first thing in the morning. Drinking water throughout the day and consuming hydrating foods like fruits and vegetables can help prevent dehydration.


Some medications might cause dizziness as a side effect. These may include blood pressure medications, antidepressants, sedatives, and antipsychotics. If you're experiencing dizziness upon waking and you're taking medications, it's important to discuss your symptoms with your healthcare provider. They may adjust your dosage or switch you to a different medication to alleviate the dizziness.

Anxiety and Stress

Anxiety and stress can manifest in physical symptoms, including dizziness. When you're stressed or anxious, your body releases stress hormones that can affect your blood pressure and heart rate, leading to feelings of lightheadedness or dizziness. Managing stress through relaxation techniques, counseling, or medication can help reduce these symptoms.

Sleep Disorders

Certain sleep disorders, such as sleep apnea or insomnia, can disrupt sleep patterns and lead to dizziness upon waking. Sleep apnea is a condition characterized by pauses in breathing during sleep, leading to decreased oxygen levels in the blood. Insomnia can result in poor sleep quality and daytime fatigue, which can contribute to feelings of dizziness. Treating the underlying sleep disorder can help improve your overall sleep quality and reduce dizziness.

Low Blood Sugar

If you have diabetes or are prone to low blood sugar (hypoglycemia), not eating for an extended period, such as overnight, can lead to dizziness when you wake up. Eating a balanced breakfast that includes protein, healthy fats, and carbohydrates can help stabilize your blood sugar levels and reduce the risk of dizziness.


Anemia is a disorder defined by a lack of red blood cells or hemoglobin in the blood, which can cause diminished oxygen delivery to tissues and organs. Common symptoms of anemia include fatigue, weakness, pale skin, and dizziness. Treating the underlying cause of anemia, such as iron deficiency, vitamin B12 deficiency, or chronic disease, can help alleviate these symptoms.

What You Can Do?

  • Stay hydrated throughout the day, and drink water upon waking to prevent dehydration.
  • Avoid sudden movements when getting up from lying down or sitting to reduce the risk of orthostatic hypotension.
  • Practice stress-reducing activities such as meditation, yoga, or deep breathing exercises to manage anxiety and stress.
  • Ensure your bedroom is well-ventilated and cool to promote better sleep quality.
  • If you suspect an underlying health issue, consult with your healthcare provider for a proper diagnosis and treatment plan.


Waking up dizzy can be caused by various factors, ranging from benign to more serious. Understanding the potential reasons behind your dizziness can help you take the necessary steps to address it. If you're experiencing frequent or severe dizziness, it's important to seek medical advice to rule out any serious underlying conditions.
