CONSCIOUSNESS AND SLEEP CYCLE

Is sleep considered to be a state of consciousness? Consciousness is a state of mindful wakefulness in which people are aware of themselves, their surroundings and are able to perceive and process stimuli around them. The consciousness of every awake person is clear. Sleeping people, on the other hand, enter a state of altered consciousness because their brains are active even if they are not moving or speaking. As people fall asleep, they go through different stages. And there are three important stages of sleep that a person goes through before and during sleep: NREM, N1-N2-N3, and REM sleep.

         NREM is the first stage of sleep, accounting for the majority of sleep. It is divided into three stages, N1, N2, and N3, each with its own characteristic. They differ in terms of sleep depth and also sensory and motor disconnection. During the NREM stages, breathing, heart rate, and blood pressure all gradually decrease. The muscles are not paralyzed during NREM sleep, as they are during REM sleep. The body's processes, mainly in the brain, only slow down. And at this stage, consciousness is closed.

The three stages of NREM are the second stage of the sleep phase. During N1, your brain slows down, as does your heartbeat and breathing. During N2, you lose awareness of your surroundings, your body temperature drops, your eye movements stop, and your breathing and heart rate become more regular. During N3, your muscles are completely relaxed, your blood pressure drops, your breathing slows, and you enter your deepest sleep.

REM sleep is the final stage of the sleep cycle, and it is a much deeper sleep than the other three stages. The activity of your brain during this stage most closely resembles that of your brain during waking. However, your body is temporarily paralyzed, which is a good thing because it prevents you from acting out your dreams. Your body is relaxed and immobile, your breathing is faster and irregular, your eyes move rapidly, and you dream during this stage.

In summary, there are three stages of sleep: NREM, N1-N2-N3, and REM sleep. The first stage is NREM, which is divided into three stages. People gradually fall asleep during these stages. We begin to dream in REM sleep, the final stage. All of these stages are necessary for a restful night's sleep. Because a good night's sleep equals a good life.

CIRCADIAN RHYTHM

WHAT IS CIRCADIAN RHYTHM?      Circadian rhythm is a person’s mental, physical, and behavioral pattern within a 24-hour period. Most living organisms, including animals and plants, have a circadian rhythm. How a person responds to light and darkness largely impacts this area of our lives.  Your circadian rhythm plays a significant role in when you sleep, and when you naturally wake up.      In short, this is your body’s internal clock that works to stimulate you to do something at the appropriate time. A small portion of the brain called the suprachiasmatic nucleus is the part of the brain that controls the internal clock. Your body will respond to darkness. The body senses the lack of light and thinks that it’s nighttime, and it is time to sleep soon. Therefore, as the sun goes down, you may notice yourself become tired.      The main reason for this has to do with light. The sun produces blue light in the morning and blue light signals to your body that it is time to get up. However,

SLEEP STAGES & SLEEP CYCLE

  WHAT ARE THE STAGES OF SLEEP?   When you sleep, your brain goes through natural cycles of activity. There are four total stages of sleep, divided into two phases: Non-REM sleep happens first and includes three stages. The last two stage of non-REM sleep is when you sleep deeply. It’s hard to wake up from this stage of sleep. REM sleep happens about an hour to an hour and a half after falling asleep. REM sleep is when you tend to have vivid dreams.   As you sleep, your body cycles through non-REM and REM sleep. You usually start the sleep cycle with stage 1 of non-REM sleep. You pass through the other stages of non-REM sleep, followed by a short period of REM sleep. Then the cycle begins again at stage 1. A full sleep cycle takes about 90 to 110 minutes. Your first REM period is short. As the night goes on, you’ll have longer REM sleep and less deep sleep. What Is the Sleep Cycle?   Sleep is not uniform. Instead, over the course of the night, your total sleep is made up of several

  CIRCADIAN RHYTHM What happens if the human body's biological clock is disrupted? Sleep is critical for humanity because some vital physiological repairs that are required can only be performed while sleeping. The circadian rhythm in the human body is also important for sleep because it is responsible for the secretion of hormone s such as blood pressure regulation, melatonin , and growth hormone. As a result, disrupting this rhythm can cause many diseases. Three important solutions can be implemented to avoid these diseases: not using technological devices before going to bed, avoiding jet lag, and not working night shifts. The first important problem of disturbance of the circadian rhythm is the lights emitted by electronic devices. Because the sun emits blue light in the morning and sends signals to the human body that it is time to wake up. When people look at their phones right before bed, they expose themselves to blue light, which wakes them up. For these reasons, elec
