As human beings continue to explore their own mysteries, the ancient and mysterious question of why people dream has gradually been revealed.
We often hear conversations like: "I had a sweet dream last night" and "Why don't I always dream?"."So, do dreams have to be in sleep?
If so, why do some people say they slept soundly last night and didn't dream?In fact, dreams are a phenomenon that accompanies everyone's sleep, regardless of whether they remember what they are in the dream the next day or not. Just like the sun in the sky, even if it is cloudy and cloudy, you can't feel its light and heat, but it still hangs in the sky. Again, whether or not you remember whether you dreamed the night before or not does not change the fact of dreaming.
Some researchers speculate that dreams are an indispensable physiological phenomenon of the human body, just like heartbeat and breathing, although not so crucial, but indispensable.
Because studies have found that the body temperature of warm-blooded animals is lower during sleep than when they are not sleeping5 degrees. This explains why we feel relaxed when we wake up, as the body temperature decreases and the body needs relatively little energy to maintain the temperature. This also shows that dreams are an essential part of human beings, because the body temperature decreases during sleep, and the brain needs to keep functioning, dreaming is the only way the brain functions during sleep.
The brain is an amazing organ that secretes various chemicals to maintain all the body's activities when it is active. Dreaming is no exception, we often say "think during the day, dream at night", there is a scientific basis, because dreaming is caused by chemicals secreted by the brain.
To put it simply, during the day, neurons are stimulated by the outside world to produce different secretions, which are recorded in the brain. At night, the brain needs to process these secretions, choosing the non-essential ones to release. This process of release is dreaming, which relaxes the brain. The generation of dreams, as we often say, "thinking during the day and dreaming at night", can be explained.
Over the course of a long period of evolution, the human brain has gradually developed a mode of operation that is very conducive to our survival. When we are sleeping, our brains are still constantly paying attention to our surroundings and our daily work experiences.
In this way, after waking up the next day, we can quickly put ourselves into a new job, or in an emergency when we can't sleep, the brain can adapt to the environment without rest in the shortest possible time and continue to work efficiently.
To sum up, dreams have become an essential element in our lives. Its importance is mainly reflected in the following aspects:
First of all, dreams can reduce the pressure on our brains, just like removing garbage from a computer, cleaning up some useless secretions in time to keep our brains functioning efficiently
Secondly, dreaming is also a way for the brain to maintain its normal working temperature, dreams are the activity of the brain during sleep that raises the temperature of the brain and maintains its normal functioning environment;
Finally, the brain is constantly working and remembering in order to adapt to the external work environment faster and better, and to improve people's work and Xi efficiency. Therefore, we can assert that dreams are essential for human beings.
These findings not only help us better understand the nature of this mysterious phenomenon, but also provide a scientific basis for formulating targeted programs. In the future, with the continuous progress and innovation of medical technology, I believe that we will be able to explore the mystery of human dreams more deeply and make greater contributions to human health and happiness.
