According to a study, a good night's sleep can help your memory is stronger, such as remembering faces and names of new people.
The researchers showed 20 facial images contain information on the names to the 14 volunteers were in their 20s. Twelve hours later, the participants were asked if they still remember the faces and names of photos that have been shown previously.
The test is performed twice, when participants slept for eight hours, and when they perform their daily activities.
After sleeping, 12 percent of them were able to mention the face following the name correctly.
How long or how deep the participants do not affect their ability to match names and faces. Other research focuses on the importance of these factors, according to the authors of a study published in the journal Neurobiology of Learning and Memory.
"We know that various memories enhanced by sleep. While several studies have looked at how nap can affect our ability to learn the names and new faces. There are no previous studies that study and examine the impact of sleep quality on evening," said researcher correspondent Jeanne Duffy Brigham and Women's Hospital in Boston. Duffy is a division associate neuroscientist sleep and circadian disruption in the hospital.
"We found that when participants were given the opportunity at night's sleep, their ability to identify the name associated with the makeup properly, and their confidence in the answer, increased significantly," said Duffy, quoted from Health, Sunday
The findings suggest that getting a good night's sleep after learning new things, can help people retain the information.
The study was conducted on young adults. The author would like to do similar research to people of all ages, including older adults.
"Sleep is very important to learn new information. The age, people are more likely to develop the disorder and sleep disorders, which in turn causes memory problems," said Duffy.
"By overcoming sleep problems, we can affect the ability of people to learn things at all ages," she said.
