Why do tourists do not sleep well on his first night away? – ViveUSA

During long trips to a new site, is common that tourists can not sleep on the first night in the hotel or house where staying and that is because the brain people acts like a dolphin, ie half remains awake for alertness. What reason do

is due.

To tell the site Smithsonian, the tendency to sleep badly on the first night in a new city or tourist destination is well documented, but the causes of which are still unclear . A new study from the Brown University suggests that sleepiness can occur because one side of the brain renounces the dream to act as a “night watch” able to warn us about the dangers.

“When a subject enters a laboratory on the first night (for a sleep study), take longer to fall asleep, wake up often in the middle of the sleep session and duration of deep sleep is shorter than usual, “Masako Tamaki.

During sleep, the movements of a person’s brain goes through a series of steps , each of which has a different electrical signature and is associated with a different depth of sleep.

Tamaki and his team focused on the deepest form of sleep called slow-wave sleep, which is when we are most vulnerable. started inviting a group of subjects to sleep in the laboratory for two consecutive nights. Each participant was connected to several instruments that measure activity levels in four networks within each hemisphere of the brain.

On the first night, the amount of activity slow waves in the left hemisphere of the brain of the sleepers was significantly lower than in the right hemisphere . But the second night, the two hemispheres were similar, as seen in previous studies of the brain. These differences in sleep between the two hemispheres were deeper in automatic mode of the brain.

Based on these findings, Tamaki and his colleagues were curious if the lighter sleep on the left side of the brain of the subject allowed to follow more closely the environment of potential hazards , similar to what has been documented in animal studies. The researchers exposed a new group of subjects to unusual sounds, mixed with high-pitched “beeps” regular sleeping presented every second during slow-wave sleep. Sound patterns were played separately to the right and the left ear, each of which transmits signals to the opposite hemisphere of the brain.

During the first night sleep disturbance, the left hemisphere showed increased activity in response to sounds right. These differences occur only in response to irregular sounds, which were designed to simulate unusual and possibly dangerous. Again, this hemispheric imbalance disappeared on the second night
