Most of us don’t care for it or don’t think about it. But is it really this harmless? Are we sure about it? who will answer this question? I searched for it in google for dizziness after woke up but nowhere I got a perfect and simple answer. So as a doctor I think it’s my responsibility to enlighten you about it.

Dizziness is a term used to describe a range of sensations, such as feeling faint, woozy, weak or unsteady. Dizziness that creates the false sense that you or your surroundings are spinning or moving is called vertigo. Learn more about dizziness.

Hair cell movements

In our inner ear, there is a semilunar canal. the balancing hair situated there. It provides the necessary information to the brain to maintain balance. In this image, you can see how it occurs normally when someone is standing normally. And how it spins while we are rotating. This is the reason why we feel dizziness right after we spin. Because we may stop spinning but the hair is still spinning in the liquid.

The same case, when we wake up suddenly after sleeping. It takes some time to be balanced. But if you feel dizziness every time after waking up and every time it takes more than 5-10 seconds, then you have to learn more about it. Maybe you have some condition that accelerating it.

Sleep apnea causes dizziness when waking up

Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. If you snore loudly and feel tired even after a full night’s sleep, you might have sleep apnea.

What are the primary symptoms of sleep apnea?

  • Loud snoring.
  • Episodes in which you stop breathing during sleep — which would be reported by another person.
  • Gasping for air during sleep.
  • Awakening with a dry mouth.
  • Morning dizziness
  • Difficulty staying asleep

You may already understand it how sleep apnea is related to morning dizziness. But for those who did not understand it, let me help you.

Sleep apnea interrupts your breathing. That’s why your body receives less oxygen than it’s needed. With low oxygen levels, your body fails to maintain proper balance.

Exsiccosis(dehydration) causes dizziness when waking up

Dehydration is also a cause of dizziness in the morning. Causes of dehydration?

  • Diarrhea – the most common cause of dehydration and related deaths. …
  • Vomiting – leads to a loss of fluids and makes it difficult to replace water by drinking it.
  • Sweating – the body’s cooling mechanism releases a significant amount of water. …
  • Diabetes – high blood sugar levels cause increased urination and fluid loss.
  • Alcohol consuming.
  • Diuretics intake (carbonated beverage, caffeine)

if you sleep in hot environment or a very small room you may face dehydration also.

Hypoglycemia (low sugar) causes dizziness when waking up

Glucose, a form of sugar, is the primary source of energy for every cell in the body. Because the brain is so rich in nerve cells, or neurons, it is the most energy-demanding organ, using one-half of all the sugar energy in the body.

Brain functions such as thinking, memory, and learning are closely linked to glucose levels and how efficiently the brain uses this fuel source. If there isn’t enough glucose in the brain, for example, neurotransmitters, the brain’s chemical messengers, are not produced and communication between neurons breaks down. In addition, hypoglycemia, a common complication of diabetes caused by low glucose levels in the blood, can lead to loss of energy for brain function and is linked to poor attention and cognitive function. Learn more about it.

Symptoms of hypoglycemia

  • An irregular or fast heartbeat.
  • Fatigue.
  • Pale skin.
  • Shakiness.
  • Anxiety.
  • Sweating.
  • Hunger.
  • Irritability.

If you face those symptoms regularly or very often then please don’t hesitate to consult with a doctor and be tested for hypoglycemia.

So, it’s clear when you are hypoglycemic, your brain cannot work properly and occurs dizziness very often especially in the morning just after waking up because of not taking food for at least 6 hours.
