What is sleep inertia?

For Danny, sleep inertia (also called sleep drunkenness) is a typical part of waking up.

Beth, a PERSON living with IH:

Before my IH diagnosis, I didn't know why after 8-12 hours of sleep I still felt partially asleep; it affected my functioning in so many ways."

How does Idiopathic Hypersomnia compare to other conditions?

Idiopathic Hypersomnia is often confused with other conditions where excessive daytime sleepiness (EDS) occurs. These conditions include obstructive sleep apnea (OSA), depression, narcolepsy (Type 1 and 2), ADHD (attention-deficit/hyperactivity disorder) and other psychological or psychiatric disorders.

It's important to know how Idiopathic Hypersomnia is different. People with Idiopathic Hypersomnia may:

  • Sleep a lot but wake up feeling just as tired as before
  • Have a very hard time waking up in the morning or after naps
  • Struggle to focus for more than 1 hour at a time
  • Do certain things without being fully awake

It can take up to 15 years for Idiopathic Hypersomnia to be diagnosed.

Which is why it's important to get the right diagnosis to find an effective treatment.
