Your personality controls your behaviour, temperament and reactions. Even if you’re super laid back in the day, you may still have sleep troubles at night. If you suffer from insomnia, it can sometimes feel like you’re fighting a losing battle. It’s often difficult to pin down exactly why some people struggle to sleep so much as there are so many factors to consider. So, why are sleep and personality connected?
We’ve all woken up on the wrong side of the bed in the morning, but studies have shown that consistent sleep deprivation can actually change your personality. Even one night of disturbed sleep can make you less able to control your emotions according to a research carried out at Tel Aviv University. They concluded that when we lose sleep, our brain cannot decipher between what’s important and what isn’t. It means we take take trivial things to heart when we would usually ignore them.
This is because the part of the brain responsible for emotions – the amygdala – is impaired when our sleep is ruined. It becomes disconnected from the area of the brain that is partially responsible for decision making – the medial prefrontal cortex. The disconnection of the two makes it very difficult to regulate our feelings. So, even the most chilled person could become an ogre or a sobbing mess after a bad night’s sleep.
A 2017 study recently published in Brain Sciences investigated the relationship between insomnia and personality type. They tested 2,089 participants with a questionnaire that deciphered their personality traits and the severity of their insomnia. The participants were then sorted into personalities: extroversion, agreeableness, conscientiousness, openness and neuroticism.
The research showed that neuroticism had the strongest links and severity of insomnia. Unsurprisingly, people with a neurotic personality type are prone to depression, anxiety, mood swings and emotional instability. The study also showed that neurotic participants were more likely to have their lives negatively affected by insomnia and have overall sleep troubles including difficulty getting to sleep, staying asleep and waking up early.
People with a highly conscientious personality reported trouble staying asleep but said this did not affect their daily lives. Again, this is understandable as conscientious people are planners, self-disciplined and attentive.
Openness and agreeableness were somewhat related to insomnia severity but extroversion had no correlation.
So, if you fall into the neurotic or conscientious personality brackets, it’s likely that you are prone to suffering with insomnia more than others. The research also concluded that understanding how personality affects sleep could be a huge step forward for Cognitive Behavioural Therapy. It’s thought that it could help the way therapists approach individuals based on reactions and behaviours usually associated with their personality.
