Statistics of Hypersomnia and. Insomnia in a post about Hypersomnia vs. Insomnia


Hypersomnia makes people very sleepy during the day. People with it want to nap a lot. There are two types: primary and secondary Hypersomnia. [1][3].

  • Primary Hypersomnia: People sleep a lot during the day, and we don't know why.
  • Secondary Hypersomnia: People are very sleepy because of other problems like sleep apnea, narcolepsy, or medicine side effects.

Insomnia makes it hard for people to sleep. They can't fall asleep or stay asleep easily. This makes them tired during the day. There are two types: acute and chronic insomnia.[4]

  • Acute Insomnia: It's short-term, lasting days or weeks. It's often due to stress or changes in life or surroundings.
  • Chronic Insomnia: It's a long-term problem that lasts over a month. It can be caused by health issues or medicines.

Prevalence of Hypersomnia and Insomnia

  • Insomnia: According to various studies, up to 30 percent of adults have insomnia at some point in their lives[10].
  • Hypersomnia: According to NIH, approximately 4- 6% of people have Hypersomnia [11].

Hypersomnia and Insomnia Causes


These two sleep problems are related. Insomnia's causes are simpler, while Hypersomnia's are more complex. But, causes of insomnia can also lead to Hypersomnia. This is because problems like insomnia or sleep apnea can make someone have Hypersomnia[1].


The causes of insomnia include[2];

  • Age- Older people are more prone to insomnia
  • Sex- Women are more prone to insomnia
  • Family history and genetics- If a family member has insomnia, then you may be more prone to developing it.
  • Stress and anxiety- Stress and anxiety can make it hard to fall asleep or stay asleep.
  • Certain medications- such as antidepressants, can also cause insomnia.
  • Environment or occupation changes- Changing work hours or changes in light, noise, or temperature can cause insomnia.
  • Caffeine, alcohol, and nicotine- Consuming too much of these substances can cause insomnia.
  • Other lifestyle changes- Having a baby, starting a new job, working out late, or eating a big meal before bed can cause insomnia.
  • Medical conditions- Some health problems like asthma, allergies, arthritis, and back pain can make sleep hard.

On the other hand, Hypersomnia is caused by[1];

  • Certain medical conditions- such as multiple sclerosis, encephalitis, depression, epilepsy, or obesity
  • Drug or alcohol misuse
  • Disruption to the normal functioning of a part of the nervous system
  • Physical problems- such as head trauma, tumors, or injuries to the central nervous system

Verdict: The causes of insomnia are more straightforward than the causes of Hypersomnia. Nevertheless, the underlying cause of Hypersomnia can be insomnia itself. It's also important to understand that the root cause of sleep disorders can be genetic, sometimes.

Types of Hypersomnia That You Should Know

Primary Hypersomnia (Idiopathic Hypersomnia)

Primary Hypersomnia means you're very sleepy during the day even if you sleep well at night. We don't know why it happens.


  • Persistent daytime sleepiness
  • Long sleep episodes at night (more than 10 hours)

  • Cataplexy (sudden loss of muscle control, often triggered by strong emotions)


  • Type 1 narcolepsy is caused by a deficiency of hypocretin, a neurotransmitter that regulates sleep-wake cycles. The deficiency is often due to an autoimmune reaction that destroys hypocretin-producing neurons.
  • The cause of Type 2 narcolepsy is still unknown.

Levin Syndrome, also called Sleeping Beauty Syndrome, is a rare type of Hypersomnia. It makes you sleep too much for days or even weeks, over and over again.
