It is only fitting for me to put together a blog post on this as I’m now in my 3rd week of going to bed and not being able to fall asleep easily. It’s a total pain in the ass but at least I’m not alone. I have scoured the internet for survey data and stats on insomnia to put together in this fact sheet. I’m not sure what to take away from this other than serious sleep problems are nested into every day life for many people, often met with puzzlement to their doctors who don’t know how to help them.
Statistics on Insomnia
Here’s a snapshot of insomnia related statistics. All this data comes from university and government sources. I have an included a link for each data source. I believe all this data is specific to surveying US residents.
- Roughly 50% of all cases of insomnia have no identifiable cause.
- 1 in 3 people have insomnia
- …but 80% never report it to their doctor
- Somewhere in the range of 40% to 60% of people with insomnia also show signs of depression.
- Between 10% to 30% of kids are affected by insomnia – specifically 1 or 2 types known as sleep-onset or limit-setting insomnia.
- Lifelong insomnia that starts in childhood and is unexplainable is present in about 1% of young adults. This is known as idiopathic insomnia.
- About 30% of adults show symptoms of insomnia, but chronic insomnia effects under 10% of adults.
- Secondary insomnia – in which sleep problems are the effect of a prior condition or cause – effects 80% of people who have insomnia.In other words, most peoples insomnia is caused by something else.
Note: This data set is a bit short due to most insomnia statistics simply repeat the same findings over and over.
