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,” he explained in an interview with Health. “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,” he said. “And that’s what insomnia is—it’s this kind of survival mode of sleeping.”
It's a similar story with perfectionists. Often, their 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're 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. After all, who doesn't deserve a full eight hours?
