According to a new paper published in Lancet Psychiatryonly, further evidence suggests that insomnia is link to certain personality traits, with many linked to negative moods.
Analysing, 2224 patients suffering from insomnia between 2010 and 2016, a team of researchers from Netherlands Institute for Neuroscience found a link between insomnia and five personality types.
The five different personalities are:
- “Highly distressed” - people who are wired or anxious before bedtime while also prone to depression.
- “Moderately distressed, reward sensitive” - again, they're wired before sleep, but aren't necessarily always having negative thoughts. They reported higher than average levels of insomnia due to stress
- “Moderately distressed, reward insensitive” - unlike the second personality type, these people tend to be unhappy or pessimistic. Although, often in a negative mood, these personalities aren't as likely to have diagnosed depression as type 2.
- “Slightly distressed, high reactivity” - This personality is like to have insomnia because of life events - financial or relationship difficulties. Their troubles with insomnia also tend to last longer.
- “Slightly distressed, low reactivity” - like type 4, this personality struggles because of life events, but they don't necessarily feel the effects as heavily. More likely to be diagnosed later in life and show high levels of demotivation.
According to sleep specialist Rafael Pelayo from the Stanford Sleep Medicine Centre, this is what researchers have believed for years.
“People sleep best in states of serenity,” says Pelayo speaking to Health.com.

“You sleep best when you feel safe, comfortable, and loved.”
Pelayo suggests that when you go to bed in a restless state, your body will stay awake, waiting for the troubles to pass.
“It goes into a mode of sleeping where it sleeps in spurts and gets as little sleep as possible,” Dr. Pelayo continues. “And that’s what insomnia is—it’s this kind of survival mode of sleeping.”
It's similar with perfectionists. Often, they're brains won't rest with any problems unsolved.
“People who are perfectionists or have obsessive-compulsive disorder tend toward insomnia because they try to fix things, and you only fix things by staying awake,” he adds. “[Insomnia] can be a thinker's condition.”
If you are struggling with shut-eye at night, it's important to address the problem. Insomnia is treatable, so check-in with your GP who can refer you to a sleep specialist. Who doesn't deserve eight hours a night?
