Ever wondered why is it so difficult to fall asleep in a new place? Did you think it was because of a different bed, sheets or the pillow? The researchers have found out why one finds it hard to get a sound sleep in a change of environment, it is because of our alert brains.
The researchers during a recent study found out that people struggle to fall or stay asleep in a new location because half of our brains remains alert whenever we attempt to sleep in a change of location.
The researchers reached the findings after observing a group of people who were asked to sleep in the laboratory, the researchers even played quite sounds by the ears while they were sleeping or trying to sleep.
The researchers on prior trials based on sleep patterns have also noticed that the participants have trouble getting a sound sleep on the first night, the scientists have even devised a name for this sleep phenomena called the first-night effect or FNE. The researchers at Brown University however, wanted to understand as to why the sleep disturbance occurs on the first night.
During the study trial, the researchers wired the participants with brain-monitoring equipment and played quiet, infrequent beeps by the ear of every sleeper. During the experiment, the researchers found out that at night time the left side of the brain reacted more strongly to the beeping than the right side of the brain of the sleepers.
The researchers also found out that the noises played on the left side of the ear woke more people up than the noises played by the right side of the ear. The left side of the brain is associated with thinking that is required for vigilance.
Commenting on the findings of the study, co-author of the study and a research associate at Brown University, Masako Tamaki said, “Well, you might be able to reduce first-night effect, but we are not really sure if you can remove the effect completely,” CNN reported.
The findings of the research were published in the journal Current Biology.
