When you're away from home, whether it's on vacation or on a business trip, the first night is always so sleepy. It's no longer just a matter of unfamiliarity, but the latest scientific research has unraveled the deeper mysteries of this phenomenon and shed new light on it.
In the wild, whales, dolphins, and some soaring birds keep half of the brain faintly alert when they sleep. Once upon a time, we thought that the human brain was completely shut down when we fell asleep, but this belief has been turned on its head in the latest research.
The latest experiment used cutting-edge neuroimaging techniques to provide an in-depth analysis of the brain's sleep patterns of 35 volunteers during two nights spent in an off-site lab. Surprisingly, on the first night, the volunteers' left brain neural network was more active than the right brain. The answer to why the left brain chooses to stay awake is always at this time.
Even more amazingly, the experiment found that the left side of the brain responds more strongly to sound than the right side. Perhaps this explains why outside voices are always so easy to disturb our tranquility in an unfamiliar environment.
Scientists have made an interesting suggestion that bringing our own familiar pillow to a hotel or other place to stay may reduce our sense of strangeness in a "foreign land**". The familiarity of the pillow seems to create a friendly little nook for us, which will hopefully improve the sleeping experience in the new environment.
In order to gain a deeper understanding of the mysterious activity of the left brain on the first night, scientists plan to turn off the "awake" state of the left brain through transcranial magnetic stimulation, in the hope of improving the quality of our sleep in an off-site location. This cutting-edge experiment may open a new chapter in the subtle connection between the brain and sleep.
The confusion of not waking up on a strange night may not only be unfamiliar with the environment, but also related to our complex and changeable brain activity. Perhaps, the pillow is the most intimate companion for us when we travel far away, and the continuous exploration of science will lead us to a deeper understanding of the mystery of why it is always difficult to sleep in a foreign place.
