The posture you sleep in says a lot about your personality

Researcher Chris Idzikowsky, coordinator of the UK Sleep Institute, studied the six most common postures humans use while sleeping. The research findings revealed that each position is associated with a particular personality profile.

This study complements another that analyzed the posture in which we sleep with our partner and what it tells us about the quality of the relationship. In this case, Idzikowsky collected the correlations between sleeping in a certain position and personality traits.

Sleeping posture and associated personality

fetal position

People who sleep in the fetal posture they tend to give a social image of confident and tough people, but they are, in fact, sensitive.

They can be shy when they don’t know the people around them, but they quickly lose their inhibition and like to express themselves without taboos. This position is the most observed in the study, as more than 40% of the 1,000 research participants adopt it for sleeping.

in the trunk

This posture, which was observed in 15% of subjects, consists of sleeping on your side, but with the arms and legs extended, forming the body a rigid stick.

People who take this position are certainly sociable and enjoys being part of social circles. They are confident even with strangers and can sin by being overly naive.

the speaker

Very similar to the trunk pose, but with the arms extended forward. People who sleep in this position tend to be more open and outgoing..

In turn, they are reluctant to decide their life and can be cynical. 13% of participants slept this way.


Upside down, lying down.

These people are shown reserved and calm. They are also demanding and have high aspirations. 8% of participants slept in the soldier’s pose.

Upside down

These are people who they feel very comfortable talking and sharing with others, And with a strong dose of openness to new experiences. They represented 7% of the sample.

It is also true that they tend to be more sensitive and restless than usual. They do not accept criticism or extreme situations.


Very loyal people, always ready to listen to others and to offer their collaboration. very empathetic. They don’t like to be the center of attention, they are quite cautious and thoughtful.

This was 5% of the total participants who slept this way; less repeated posture.

Other observations of the study

Beyond the personality considerations related to the position we adopt for sleeping, Idzikowsky also came to some health-related conclusions:

  • The upside down posture allows better digestion.
  • The soldier and starfish postures they involve ventilation difficulties, Causing snoring and poor rest.

The researcher also pointed out that changing the posture we sleep in is complicated, as habit dictates our preference when it comes to rest. Only 5% of the people who took part in the research reported sleeping in different postures each night.
