Feeling dizzy when you wake up can make you feel unrested, even after a long sleep. Although this condition often disappears within a few minutes, in some cases, the dizziness can last for hours.
Dizziness when waking up can be caused by various factors, ranging from insomnia to certain medical conditions. If left untreated, it can interfere with daily activities and reduce your quality of life.
Therefore, it is important to identify the exact cause and the proper way to deal with it. Read this article for more information!
Causes of Dizziness When Waking Up
Feeling dizzy upon waking up is actually quite common. However, if this condition persists and recurs, you need to identify what triggers it.
The causes of dizziness when waking up include BPPV and orthostatic hypotension.
BPPV is a disorder of the inner ear usually triggered by changes in head position. Meanwhile, orthostatic hypotension is a condition where blood pressure drops rapidly when standing up from a sitting or lying position.
Here are some other possible reasons why you might feel dizzy when waking up.
1. Insomnia
The first reason why your head feels dizzy when you wake up is insomnia. Usually, you have difficulty falling asleep, can’t sleep deeply, or wake up early in the morning and then cannot go back to sleep.
Insomnia reduces the quality of your sleep and makes you two to four times more likely to experience dizziness when you wake up in the morning.
2. Sleep Apnea
Another cause of dizziness upon waking is sleep apnea. This is a sleep disorder that causes a person to stop breathing for short periods during sleep.
Sleep apnea can disrupt sleep routines and lower oxygen levels in the brain, causing sufferers to experience headache symptoms and fatigue when waking up in the morning.
Additionally, sleep apnea is characterized by symptoms such as snoring, choking during sleep, and waking up with a dry mouth.
3. Wrong Sleeping Position
Sleeping in the wrong and uncomfortable position can also cause waking up with a dizzy head.
For example, sleeping with the pillow too high can cause muscle tension. In addition, the neck and head can also become stiff because you remain in the same position for a long time during sleep.
4. Depression and Anxiety Disorders
Another reason for feeling dizzy upon waking up is due to mental health issues such as depression and anxiety disorders.
These two conditions often disrupt sleep, making you more likely to experience headaches upon waking the next morning.
5. Migraine
Migraines or headaches can make the head feel dizzy when waking up.
The exact cause of migraines is not yet known. Still, the condition is suspected to be caused by neurological disorders and changes in brain activity that affect nerve signals, chemicals, and blood vessels in the brain.
Migraines are usually triggered by poor sleep quality, including insufficient sleep or excessive sleep. In this condition, migraine attacks often occur in the morning, especially around 8–9 a.m.
6. Dehydration
Dizziness when waking up can also be caused by dehydration. When you are dehydrated, your body will feel weak, thirsty, and dizzy. Dehydration occurs due to not drinking enough water, the bedroom being too hot, or consuming too many caffeinated drinks.
7. Low Blood Sugar
Do you have diabetes? If so, the dizziness you experience when waking up may be due to antidiabetic medications, such as insulin. These medications work to lower blood sugar levels in the body.
Side effects that may occur include weakness, trembling, cold sweats, and dizziness.
8. Orthostatic Hypotension
According to health experts, orthostatic hypotension is a condition in which a person's blood pressure drops significantly when standing up from a sitting or lying position.
This drop in blood pressure can cause dizziness, blurred vision, or even fainting due to a temporary decrease in blood flow to the brain.
This condition is caused by the body's inability to quickly adjust blood pressure when there is changes in body position.
9. Heart Failure
Dizziness when waking can also be caused by heart failure, a condition in which the heart is unable to pump blood effectively throughout the body.
This means the heart cannot meet the oxygen and nutrient needs required by the body's organs and tissues. This condition can develop gradually (chronic heart failure) or suddenly (acute heart failure).
10. Benign Paroxysmal Positional Vertigo (BPPV)
Benign paroxysmal positional vertigo (BPPV) occurs when small calcium particles (otoconia) that should be in the inner ear move from their normal position into the semicircular canals while you sleep.
This change in position makes the nerves in these canals more sensitive, which can cause dizziness, nausea, vomiting, and even loss of balance.
11. Consumption of Alcoholic Beverages
Alcohol can trigger migraines and sleep disorders that reduce sleep quality. If consumed excessively, alcohol can cause a hangover accompanied by symptoms such as dizziness, headache, fatigue, and nausea.
In addition, the diuretic effect of alcohol can also cause mild dehydration, which increases the risk of headaches upon waking in the morning.
12. Iron Deficiency
Low iron and hemoglobin levels can reduce oxygen delivery to body cells during sleep, causing dizziness upon waking.
Iron deficiency also increases the risk of anemia, a condition in which the body lacks red blood cells. When the body lacks red blood cells, oxygen delivery is disrupted, which can cause morning dizziness and headaches.
13. Sleeping Too Long
Oversleeping can also cause dizziness when waking up. Sleeping longer than usual often indicates poor sleep quality, which increases the risk of dizziness upon waking.
14. Side Effects of Medications
The use of certain medications, such as antidepressants, anticonvulsants, diuretics, antihistamines, blood pressure medications, sedatives, and antibiotics, can cause several side effects, including dizziness when waking up.
To prevent this, make sure you follow the medication instructions carefully. In addition, consult your doctor about potential side effects that may arise from the medications you are taking.
15. Certain Medical Conditions
Persistent dizziness and headaches upon waking can be a sign of serious health problems.
Some conditions that can cause morning dizziness and headaches include uncontrolled high blood pressure, brain tumors, or other health disorders.
How to Overcome Dizziness When Waking Up
The way to get rid of dizziness when waking up depends on its cause. If certain illnesses cause dizziness, the solution is to consult a doctor to receive the appropriate treatment.
If it is caused by dehydration, the way to deal with it is by drinking plenty of water, and so on.
In addition, other steps you can take to overcome dizziness when waking up are as follows:
- Wake up slowly and not in a hurry.
- Drink enough water.
- Avoid drinking caffeinated beverages before bed.
- Consume a balanced, nutritious diet.
- Manage stress well, such as through meditation, listening to a song, and so on.
- Exercise regularly.
- Regularly check your blood sugar, especially if you have diabetes.
- Avoid napping for too long.
- Make your bedroom environment conducive by keeping the room dark, cool, and quiet.
- Get enough sleep, at least 7–8 hours every night.
