Sleep is essential for our body. Because the most complex processes of brain, eyes, ears, digestive system cannot function properly without sleep. The first symptom of insomnia is dark circles under the eyes. This is because the human skin cells cannot repair themselves when there is less sleep. It is clear from this, the beauty of our skin is directly related to sleep. Another important function of sleep is to repair the eyes. So, if you don't sleep properly, your eyesight will decrease the next day.

All sleep is controlled from the center of the brain. Behind each eye is the optic nerve, which is part of the eye and connects directly to the occipital lobe at the back of the brain. This means the eyes and brain work together to see and think.

One of the many functions of the optic nerve in the center of the retina is to maintain the circadian rhythm of sleep. Every human has its own body clock. Similarly, nature also has its own cycle of light and darkness, which is scientifically proven.
Nature's light-dark cycle and humans' own body clock work together. The optic nerve of the eye receives the natural light-dark signal, i.e. whether it is light or dark outside, and sends that information to the hypothalamus located in the middle of the brain. Suprassiamatic messages are released from here. Its job is to keep the circadian cycle of sleep going properly.
When it's dark in nature, signals start reaching the brain and the hormone melatonin is released. Melatonin is called the sleep hormone and is released at night, which helps us sleep. The secretion of this hormone stops during daylight. After waking up, the process of sleeping starts again. Adenosine is released in the body when awake. This hormone makes us drowsy. If this hormone is released, the body falls asleep after 16 hours. That means our human life is all about sleep.

Our body clock is connected to the penile gland. The pineal gland is located in the middle of the brain and regulates sleep from 9pm to 3am through 4 hormones. Along with melatonin, serotonin is a mood hormone, angiotensin is a natural pain reliever and this hormone helps induce deep sleep. Another hormone is epithelamin, which helps the brain learn and understand new things by organizing all the information it receives throughout the day.
After each hormone release, a lot of unnecessary stuff is left in the brain, which is the first part of sleep when it is cleared. This is actually the cleansing, which is the cleansing time. Eyelids are closed during sleep. However, the eyes are also connected to the brain, which can be understood from the constant movement of the eyelids during sleep. Because, again after a while it settles down. The entire sleep process goes through two processes - 'Non-Rapid Eye Movement' and 'Rapid Eye Movement'.

Everything we do throughout the day, that is, all the memories are stored in the hippocampus of the brain. During night sleep, these memories reach the cerebral cortex from the hippocampus. As a result a child or person becomes intelligent. At this time, brain cleaning also goes on in parallel.
During this time, the brain fluids remove its own and neuron's waste. It also removes all negative feelings. Insomnia disrupts this entire cycle. As a result people get amnesia. People start to forget or the brain cannot retain any information. Therefore, the biggest problem of this generation is not being able to pay attention. Because of this, people suffering from insomnia think negatively and are short-tempered.
suspect others. He lost his appetite for words. Dementia, Alzheimer's disease started. Due to lack of sleep, he suffers from jet lag. The body is constantly in the dilemma of neither sleeping nor waking up. Just as insomnia doesn't happen overnight, it takes time to get over it naturally. These will be resolved consistently.
