You are exhausted but still cannot shut your mind and fall asleep. Here, Otorhinolaryngology and Head and Neck Surgery Specialist Op.Dr.Bahadır Baykal explained what was happening in his body during a long night.
Sleep is a natural form of rest. In fact, all living things need sleep in order to perform their daily functions. We've all had sleepless nights for one reason or another. So what trauma awaits us on a sleepless night and morning? Let's examine it together ...
When the sun goes down, the brain pineal gland begins to secrete the sleep hormone melatonin. Thus, the body is reminded that it is time to sleep. When we wake up in the morning, adenosine, a chemical that causes sleep, begins to be secreted and stored in the body throughout the day. When we go to bed, it penetrates our brain with other substances and makes us feel sleepy. ABA, a neurochemical substance, gives the order to sleep by stimulating the brain stem. The next stage is sleep.
A few minutes after we go to bed, we start taking the inventory of the day in our minds. Why did I talk like that? Why did I do it? So how should I behave? Many thoughts such as begin to cross our minds. Here, the first great battle in our mind begins at that moment and the mind goes into stress. Adrenaline triggered by stress disrupts heartbeats, blood pressure, body temperature, and breathing. Cortisol, the sister stress hormone of adrenaline, starts to increase with it, so the blood sugar level rises and the mind begins to open. The fight between the sleep and wakefulness centers of the brain has now begun.
At the end of the second hour, the inability to turn around and sleep in bed breaks down the morale, and the level of adrenaline-cortisol increases a little more. We start to breathe suddenly and deeply
When we give up at the end of the third hour we spend in bed, get out of bed and turn on the TV or computer, we embrace a big mistake. The blue light emitted from the screen causes further suppression of melatonin. At that moment, our brain gets the feeling that a new day has started. Since the mind is more focused on what is watched or read than on sleep, it is the first time we come into contact with the bed. zamWe become even more alert than in the moment.
While entering the fifth hour, the sleep center of the brain wins this battle and may fall asleep for a while. However, it is not possible to fall asleep slowly like natural sleep. Intermittent and uncomfortable sleep may occur because brain waves are trapped at a high frequency.
At the end of the seventh hour, when it is time to go to work or when the alarm goes off, it is difficult to wake up immediately, as the brain enters the delta stage in the deep sleep process. Even when trying to wake up, the mind is still blurry as not enough adenosine is burned in the body. The reason a cup of coffee is needed to recover quickly is to neutralize adenosine by taking caffeine.
Since we cannot get enough rest after a sleepless night, we feel cranky and lighter than other mornings. The frontal cortex, the center of logic and concentration of the brain, has been drifted from here to there. Has difficulty focusing; We can become irritable and impulsive. However, if we manage to sleep at the right time the next night, despite everything, we can leave this trauma that night without carrying it over to the next day.
