Of course, most, if not all of us, have experienced at one time going somewhere and when you try to catch some well-deserved shut-eye, but instead what you get is a night-long struggle with tosses and turns, plus a headache at the first light of dawn.
Yes, this is not a strange or weird phenomena and no, this is not a ghost keeping you awake inside a haunted room or house, rather this is called the ‘first night effect.’
Scientists have been studying this for the past 50 years and can affect anyone or any age, as Yuka Sasaki from Brown University pointed out saying that even people who are at their prime young age and in good health still experience this 99 percent of the time.
This phenomena is also present among many mammals in the animal kingdom, where they are able to sleep with just half of their brains while the other stays awake, which nature equipped them to protect themselves from predators, allowing them to stay away from danger.
Sasaki said that it may be similar for humans, albeit in a different manner and process, for which the effect may be triggered by exposure to a new environment and their research may soon be able to determine what may be causing this phenomenon
A recent study by the group involved 11 test volunteers to participate in a laboratory test for a few nights, where they were asked to sleep in man-sized medical scanners to allow them to measure brain activity.
Electrodes were also attached to the head and hands of the test participants to measure eye moment, heart rate and brain waves among others, however, these monitoring equipment would not be able to cause them too much problems as everything is also being done to ensure their comfort throughout the test period.
The tests showed that those who were asleep undergo a slow yet synchronized pulsing of neurons that are usually associated with deep sleep which is called a slow-wave activity, where they found that this was significantly weaker in the left part of the brain of the test volunteers during their first night.
This, however, changed on the second and the succeeding nights throughout the test period.
This behavior has been observed in the animal kingdom where this has been believed to be inherent among animals as a way to protect themselves from danger in the wild.
