Whatever the situation, whatever you try, it may sometimes be difficult for you to close your eyelids and enjoy a good night's sleep when you spend a night outside your home. "Do not worry, that's normal," US researchers say.
A study published in the journal Curent Biological revealed that the left hemisphere remains "in high alert" on the first night spent in an unusual place. The human brain does not hesitate to awaken us by not repeating the emergency change and its sensitive sensitivity to external stimuli when any The movement or release of any sound the brain sees as a potential source of danger.
Abnormal activityTo illustrate this phenomenon, scientists used to study the activity of the brains of 35 volunteers in three different ways. They observed during the first night abnormal activity of the left hemisphere after sound signals to the volunteers' ears.
When the signal is directed towards the right ear - controlled by the left side of the brain - people who sleep in a deep sleep tend to wake up and react faster than those who are pointing the sound to their left ears.
The "effect of the first night" disappears, disappearing almost imperceptibly on the second night.
Animals alsoThe scientists confirm that this phenomenon is not confined to humans only, where the same reaction was observed in some animals, too, such as dolphins, whales and some birds sleeping one of their brain noses alternately, for example, whales that do not supply oxygen except through buoyancy above the sea must From a naughty brain to remain in constant vigilance to allow her to swim to the surface and to supply oxygen regularly and in a timely manner.
Scientists are advised to reduce the impact of the "first night effect" to take the person with him where he went wherever he went to give greater confidence to his left brain half and enjoy a good night's sleep outside his home.
