From Facebook to Twitter and even Instagram, social media websites allows you to form a perspective of someone—a view into his or her likes and dislikes. While social networking sites allows one to form one perception, experts suggest if you really want to know someone, observe the way he or she sleeps.

According to a study conducted by Dr. Christopher Idzikowski, the director of The Edinburg Sleep Centre, sleep positions can disclose intimate details concerning one’s personality. The study comprised of a thousand men and women, revealed the six most common sleep positions: fetal, log, yearner, solider, free-faller and starfish.

The results discovered of the thousand men and women the most common of the six was the fetal position, 41 percent of men and women are fetal sleepers. Fetal sleepers display a tough exterior, but are really sensitive and shy at heart. They also are quick to relax.

The second most common of the six is the log position. People who sleep in the log position sleep on their sides with legs and arms rested completely straight, accounting for 15 percent of participants’ preference. Log sleepers are said to be easy going and sociable, trusting of strangers, but sometimes gullible.

Those who slumbers with their arms stretched out are called yearners, which accounted for 13 percent, and came in third place. Yearners are open to nature, may be suspicious and cynical, slow to make decisions and opposed to changing his or her mind.

Soldiers, which accounted for eight percent of participants, are quiet and reserved, are more prone to avoid commotion, but have high standards.

Seven percent of participants are categorized as free fallers. Free fallers are known to have a brash and gregarious exteriors, however a really thinned skinned. Their outer confidence is masked by a response to negative criticism.

Last but not least is starfish sleepers. Starfish sleepers account for five percent. They are known to make good friends because they are listeners, offer assistance and are unpretentious. They are also happiest out of the spotlight.

Regardless of your sleep personality, it is important for one to receive adequate amount of sleep. As previously reported without a sufficient amount of sleep, the body will react to sleep deprivation the same way it would react to stressful conditions. According to the National Foundation of Sleep children between five and10 years need 10-11 hours of sleep daily, preteens and teens between 10-17 years need 8.5-9.5 hours, and adults need 7-9 hours of sleep.

Here are a few tips that may help you find the best position for you to receive a sufficient amount of rest:

  • Go to bed at the same time each night and rise at the same time each morning.
  • Moderate physical activity may help promote sleep, but avoid vigorous exercise in the few hours before going to bed.
  • Avoid large meals before bedtime.
  • Avoid caffeine and alcohol close to bedtime.
  • Avoid nicotine.
