What happens if people sleep too much

Sleep is an activity that everyone must perform every day, because our human body needs rest. However, if a person sleeps too much, it will not be good for the body. It can lead to some consequences, such as dizziness and other conditions. However, many people do not know the consequences. So what will happen if a person sleeps too much?

Sleep is something everyone needs every day , and most people spend more than one-third of their lives sleeping. The exact definition of sleep has different connotations as the times change. Initially, French scholars believed that sleep is a state in which sensory and motor activities are temporarily stopped due to the body's internal needs, and that appropriate stimulation can cause immediate awakening.

Later, people became aware of brain electrical activity and believed that sleep was a low level of physiological activity in animals caused by the functional activities of the brain, and that appropriate stimulation could bring them into a state of complete wakefulness. After years of research, modern medicine generally believes that sleep is an active process and is necessary for restoring energy. There is a special center that manages sleep and wakefulness. The human brain simply changes its working mode during sleep, which allows energy to be stored and is beneficial to mental and physical recovery. Proper sleep is the best rest, which is not only the basis for maintaining health and physical strength, but also the guarantee for achieving high productivity.

I don't entirely think so. According to my experience and understanding, sleep refers to the brain's need to distribute and solidify stimuli and stimulus connections to corresponding nerve cells (reorganize information), temporarily transferring the excitement points (attention) to nerve cells that originally had weaker excitement intensity, and those nerve cells take over most of the body's life activities. The nerve cells with higher excitement that originally received and processed internal and external stimuli and responded must prevent the stimulus connections that have not been deeply processed from interfering with each other (information overload). (It can also be understood that the biochemical energy is limited, and when awake, these nerve cells mainly receive and process stimuli, create and call stimulus connections, and when asleep, they mainly organize, filter and solidify stimulus connections.) This is a necessary life process that must largely shield the effects of internal and external stimuli on these nerve cells.

Mental fatigue is manifested as too many stimulus associations to be processed or solidified, and people's instinctive uneasiness, tension and anxiety stored in the stimulus associations. Sleep plays a role in digesting these stimulus associations, which manifests itself as relieving fatigue. Poor sleep quality refers to insufficient shielding or insufficient sleep time to fully digest stimulus associations. Sleepiness is a pathological form of excessive and prolonged shielding. These are all manifestations of insufficient neural control. During sleep, as active activities are weakened, a person's physical strength is restored accordingly. Sleep tends to be an unconscious, pleasurable state that usually occurs while lying in bed and allowing ourselves to rest during the night. Compared with the waking state, when sleeping, a person stops contacting with the surroundings, conscious awareness disappears, and he can no longer control what he says or does. When people are sleeping, their muscles relax, their nerve reflexes weaken, their body temperature drops, their heart rate slows down, their blood pressure drops slightly, their metabolism slows down, and their gastrointestinal motility also significantly weakens. At this time, the sleeping person seems to be still and passive, but in fact, if we do an EEG on a person while he is sleeping, we will find that the electrical impulses emitted by brain cells when a person is sleeping are no weaker than when he is awake.

This proves that the brain is not resting. Just like a beehive at night, it appears that the bees have returned to the hive to rest, but in fact all the bees are busy making honey all night long. Improve sleep quality: Just as everyone’s appetite is different, everyone’s required sleep time is also different. The length of sleep cannot be used to judge whether a person has enough sleep. As long as you feel energetic and alert after waking up, you have had a good sleep.
