A study published in the Royal Society Open Science journal suggests that a lack of sleep can affect people’s physical appearance.
Researchers from the Karolinskav Institute recruited 25 students (both men and women) to participate in a sleep experiment. Each student received a kit to measure how much they slept during the night, and instructed them to monitor two nights of good sleep (between 7 and 9 hours of sleep) and two nights of bad sleep (less than 4 hours of sleep).
In addition to monitoring these nights of sleep, the study included photos of the students. These photos were shared with another group of people, who scored each student based on their attractiveness, health, sleepiness and reliability. Those individuals that lacked sleep scored lower in all of these categories.
As the researchers conclude, “These results show that according to the others’ perceptions, severe sleep deprivation and having a tired appearance are related to reduced attractiveness and health.”
This analysis supports the theory that getting good sleep has a significant impact on people’s quality of life, ranging from their weight and mood to their ability to function and perform daily tasks.
