Hypersomnia causes daytime sleepiness, fatigue and excessive tiredness

Hypersomnia causes daytime sleepiness, fatigue and excessive tirednessHow much sleep did you get last night? Six, seven, maybe even up to nine hours? When we get minimal amounts of sleep it makes sense to wake up tired, but when we have prolonged amounts of sleep and still wake up tired, then we have a problem.

If you’re getting many hours of shut-eye and still can’t seem to function the following day because of fatigue, you may have hypersomnia. Don’t get it confused with insomnia, which is the inability to sleep; hypersomnia is the opposite, but still leaves you extremely tired.


Hypersomnia can affect your day-to-day life and prevent you from enjoying the things you once loved. How can you take your grandchildren to the park when all you really want to do is nap? How can you enjoy a movie when your eyes are beginning to close during the opening title?

As you can see, hypersomnia can take quite a toll, but what is hypersomnia exactly?

What is hypersomnia?

what is hypersomniaThe definition of hypersomnia is the feeling of extreme tiredness either chronically or in reoccurring episodes. Hypersomnia leaves people feeling tired even after a good night’s sleep. Hypersomnia can either be a stand-alone condition or be brought on by a pre-existing condition such as sleep apnea or other sleep disorders.

Hypersomnia makes it difficult for people to perform tasks during the waking hours as they are simply too exhausted. This, unfortunately, can lead to injury and other health concerns.

Types of hypersomnia

As discussed, there are two types of hypersomnia: primary and secondary.

Primary hypersomnia: The first type of hypersomnia is primary, when hypersomnia exists on its own. Individuals continue to feel tired, even though they are sleeping at night.

Secondary hypersomnia: The secondary type of hypersomnia occurs when a pre-existing medical condition, like sleep apnea, is present. Illnesses that cause poor quality sleep can result in the individual sleeping for many hours but not going through the necessary sleep cycles they need to awaken refreshed and energized. Such conditions include Parkinson’s disease and kidney failure.

Causes of hypersomnia

If you’ve never heard of hypersomnia before now, and feel you could fit the bill, then it’s important to note the most common causes of hypersomnia. Some of the most common causes of hypersomnia include:

  • Already present sleep disorders: sleep apnea or narcolepsy, for example
  • Sleep deprivation
  • Being overweight or obese
  • Substance use: drug and alcohol, including prescription and recreational drugs
  • Head injury
  • Neurological disease: multiple sclerosis, for example
  • Genetics: having family members with hypersomnia can increase your risk

These are the main causes of hypersomnia and should be considered when diagnosing the sleep disorder. Another main cause of hypersomnia, when discussing the primary type of hypersomnia, is having problems with the brain. This includes the brain’s ability to wake us up and go to sleep.

Symptoms of hypersomnia

symptoms of hypersomniaAside from extreme fatigue, there are other symptoms of hypersomnia to be aware of. They include:

  • Anxiety
  • Reduced appetite
  • Brain fog: reduced memory, slower thoughts and speech
  • Restlessness
  • Irritability
  • Lack of or low energy

If you have experienced any of the signs and symptoms of hypersomnia, it may be time to get them checked out, but first you should know if:

  • The signs and symptoms of hypersomnia have been present for up to six months without being associated with head trauma.
  • The signs and symptoms of hypersomnia are not a result of a pre-existing mental or medical illness.
  • Your sleep study test – polysomnography – returns normal.

If you’ve been experiencing the signs and symptoms of hypersomnia and fit into the above three criteria, then your doctor will suggest further testing or make a diagnosis of hypersomnia.

Treatment for hypersomnia

Natural treatments for hypersomnia include getting as much sleep as possible – napping may be a viable option. Stick to a set sleep schedule to ensure maximum sleep and keep your body in a routine. Avoid the use of alcohol, drugs and medications that may disrupt sleep even further. Be vocal about your condition with loved ones, so they are aware of what you are going through and will be more accepting of your challenges.

Another form of treatment for hypersomnia is to eat a well-balanced, nutritious diet, so the nutrients from the food will also promote energy within the body.

Living with hypersomnia

Living with hypersomnia can be difficult; you simply don’t have that get-up-and-go that you once had. Also, your exhaustion may even prevent you from leaving the house. Understanding hypersomnia, along with the most common causes and the signs and symptoms of hypersomnia, can give you a better chance at treatment success.

If you’ve been waking up daily and it feels like you haven’t slept in years, it may be time to speak with a doctor about your condition. Considering there are two types of hypersomnia, your doctor will check to see if the hypersomnia is on its own or brought on by an alternative re-existing medical condition.

But overall, you should never wake up tired. If your fatigue never seems to leave, seek out help. Life is better when you’re fully awake and able to play an active role!
