What is sleep?
Sleep is a phenomenon that all living things and all humans have experienced and known throughout history. A form of behavior. Even in the mythological age, perceptions and diagnoses about sleep have always been made. We even have a god of sleep, which we call "hypnosis". Sleep has always existed since the beginning of human life, but scientific approaches and data about sleep began to be defined and interpreted correctly with the development of computers, informatics and technology. Sleep is a time in which 1/3 of human life is spent.
Sleep is a function of the brain and a function of our body. After a certain amount of alertness, after the body is tired for a certain amount of time, it is the opposite of the alertness we need and it happens spontaneously. You don't need to do anything extra for this.
How do we determine our sleep needs?
The sleep needs or sleep durations of all living things. It is genetically encoded, we have no chance to change it. We are all coded in our genes for how much sleep we will get and at what hours we will sleep. We must not make mistakes in this, we must comply with our genetic codes appropriately. The duration of these genetic codes may vary from person to person, but not much. The average time we need to sleep is 7-8 hours. But for some of us, 6 or even 5 hours of sleep is enough, and for some of us, 9-10 hours is only enough. Therefore, the average normal sleep hour range is between 5 and 11 hours.
So, how does a person understand the correct sleep time encoded in his/her genetics?
We can only find the correct time in our genetically coded clock when we pay attention to the hours in which we are not exposed to any external stimuli, when we are comfortable, when we let ourselves go, when we sleep when we feel sleepy, and when we wake up when we wake up, especially when we are on holiday.
At what time should we sleep and at what time should we wake up?
The answer to this question is the same, which again varies from person to person because just as there is a genetic code for how much sleep we will have, what time we will sleep? There is also a genetic code for the hours we sleep and wake up at. Some of us go to bed early and wake up early, some of us On the contrary, we tend to go to bed late and wake up late, these are completely related to our own codes.
It is important to know your sleep type, why?
For example, you cannot get efficiency when you give night work to an employee who goes to bed early and gets up early. Or vice versa, when you ask for a job early in the morning from an employee who tends to go to bed late and wake up late, you may not get the performance you want.
What is the relationship between the body system and sleep?
When medically defining and evaluating human life, it is defined in some systems. Visual system, hearing system, circulatory system, excretory system. All of these systems show parallelism with sleep and have a communication with sleep. Our heart works very differently at night and very differently during the day. Especially the functioning of our digestive system is very different during the day and night. In other words, we need to know the relationship between our internal organs and sleep. The correct, scientifically accepted way of life for people is to eat three times a day, and to eat three times a day within 10 hours. In the remaining 14 hours, our digestive system works and our sleep period becomes active. There is no food or need in these remaining 14 hours. If we disrupt this situation, we will disrupt the digestive system and disturb sleep. Our body is coded to spend 1/3 of our lives asleep.
In the sleep department, we try to look at all organs, not just one organ, during the diagnosis and treatment process of patients. We are especially trying to record the heart rhythm and the body's oxygen use.
What is the use of sleep?
Night sleep prepares us for the next day, It is a period in which damaged organs are repaired and some enzymes and proteins are secreted. Sleep is a preparation period for activities during the day. In order for that preparation to be made, it is necessary to have a normal night's sleep in every aspect. Everything we learn during the day is actually recorded at night while we sleep. In other words, it is recorded in our memory during that process.
What awaits us in our body when we cannot sleep?
When we sleep less at night, our body will not be able to prepare for the next day. Power, energy and protein synthesis will not be possible in our body. Sleep is missing The most common complaints we encounter during our stay are weakness the next day, fatigue, headache, dizziness, loss of attention, desire to sleep, and forgetfulness. Patients mostly come to neurology with these complaints.
“Insomnia can cause forgetfulness!”
What are the periods of sleep?
We all sleep 5-6 periods a night. Each of the 5-6 periods is 90 minutes. We lie down in bed, turn off the lights, get away from external stimuli and fall asleep. This process may take 15 minutes, and after falling asleep, we sleep for 90 minutes. There may be a brief wakefulness after that. Then we sleep in the second period and third period. There are approximately 2 sections within each period; In the first part, we fall asleep slowly, the sleep deepens, then we sleep for a period called ram sleep. There are two non ram – ram periods within each period. When we look at our entire sleep, 75% is non-ram sleep and 25% is the sleep we call ram.
What is the difference between Non-Ram and Ram sleep?
Non Ram: It is the period when physical rest, protein synthesis and damage are repaired.
Ram: During the period when mental activities are carried out, memory is recorded, personality and human development are achieved. It is the RAM period.
“Not remembering the dreams we saw when we wake up means that we had a good RAM sleep period!”
Night What is the difference between sleep and daytime sleep?
The main stimulus that organizes and regulates our sleep is sunlight. As soon as the sunlight begins to enter our body, when a group of cells in our eyes are stimulated and the brain detects this, some hormones are secreted, these hormones are the hormones that enable us to be active and energetic.
What are the names of these hormones: Acadylcodine, cortisone and adrenaline; when we secrete these, we become active, energetic during the day and ensure our alertness. But the time when these hormones are secreted is when the sun's rays begin to illuminate the world.
Who is recommended for an afternoon nap?
Those who have problems sleeping at night, We recommend an afternoon nap to people who have had poor quality sleep at night. � When we sleep in the afternoon, we can be more active in the afternoon.
We need to work during the day and sleep at night, but in today's conditions, there is still a shift system. In this process, scientific research shows that even very simple diseases, such as flu and cold, can be different and more severe in people working at night. In addition, cancer cases are more common in people who work at night. Cardiovascular diseases are more common in those who work at night, and heart attacks are more common in those who work at night.
“In places where the industrial society is prevalent, it is seen that the work accident rate of those who work at night is much higher!”
Does a person who cannot sleep regularly become angry? Does he gain weight?
Many diseases and many medications affect sleep. Blood pressure, heart diseases, diabetes and eating habits are also associated with sleep. When we do not sleep at the right time and in the right way, we become out of order in every aspect. Our eating patterns are also included in this.
There are already diseases such as "eating at night, unnecessary eating, uncontrolled eating, unconscious eating" among the Sleeping Diseases.
“I talk about what I experienced during the day in my brain when I go to bed.”
When did medicine start to deal with sleep disorders?
Sleep is a phenomenon that has existed together with humanity in human history. It's already a person's way of life. But medicine's ability to accurately define and direct sleep emerged with the advancement of technology. We have been able to evaluate sleep accurately since we started recording at night, such as evaluation of EEG, physiological recordings, recording of the night, how the brain works during the night, how the heart works, how the respiratory condition is. So we can say about the last 50 years.
