What troubles will come from not getting enough sleep?
When lack of sleep accumulates for a long time, it will cause many negative effects on our body, mind and brain, the first of which is a decrease in immunity. Lack of sleep can easily lead to colds and allergic diseases, and can also increase the risk of diabetes and heart disease.
Continuous lack of sleep can lead to brain imbalance
Because the sympathetic nervous system is in a state of continuous overexcitation, the autonomic nervous system is disordered and the psychological state is difficult to maintain balance, resulting in inattention, anxiety, and inability to get motivated about anything. All of the above are phenomena of decreased brain function caused by lack of sleep.
Sleep can give a developed brain effective rest
Muscle fatigue can be eliminated by just lying down and resting, while brain fatigue must be restored through sleep. Moreover, the resting method of the brain is different depending on its location!
Our brain is divided into "sleep brain" and "command sleep brain". The former is the brain and the latter is the brainstem. In order to prevent the brain from overworking, the brainstem will issue the command "go to bed quickly". At this time, we will feel very sleepy. Of course it would be best if you listen to your brainstem and go to sleep, but in fact humans can overcome drowsiness with willpower, that is, the brain tells you "Although you are very sleepy, let's hold on a little longer!"
As a result, as a result of the brain's forced work, whether it is creative thinking ability or rational logical judgment ability, it will become worse, not to mention memory. It is impossible to remember the content of learning, because once there is insufficient sleep, the rapid eye movement period of sleep (responsible for organizing memory) is first deleted, making it difficult to remember. In other words, compressing sleep time to study or work will have the opposite effect!
Oh~ right! I forgot to mention that there is another terrible side effect of lack of sleep, which is "getting fat!" Leptin decreases and ghrelin increases, coupled with an increased appetite and a preference for heavy-flavored and high-calorie foods, it is difficult not to gain weight!
