Medical Video: What Happens To Your Body And Brain If You Don't Get Sleep | The Human Body
Have you ever slept badly and found it difficult to focus on working in the morning? Did you know that there is a connection between good quality sleep and brain function? Yes, some studies say when you are not focused on doing something, one reason might be poor quality sleep. Hmm, how is that?
What is the relationship between the quality of sleep and brain function?
When we wake up, body temperature, blood pressure, heart rate and breathing increase. During the 'deep sleep' period, one will experience four stages. Body temperature drops, muscles relax, and heart rate and breathing slow. Deep sleep enters the subconscious stage and makes physical changes in the form of increased immune system functions. One of the categories of sleep, REM (rapid eye movement) sleep is the period in which people dream. Research reports that at this stage there is an increase in learning and memory, and has an effect on emotional health.
The relationship between sleep, learning, and memory is a phenomenon that is difficult to understand. Various studies show that there is a connection between the quantity and quality of one's sleep with memory. Researchers revealed, sleep can help someone learn and remember. People who lack sleep often cannot focus attention optimally and cannot learn efficiently. Sleep also has its own role in combining memory, and it is important for the brain to learn new information.
Although there is no definite mechanism, learning and remembering can be described in three functions. The process of receiving, that is when there is an introduction to new information in the brain. The process of merging, is a process to make memory stable. After the information is stored, there is a calling process. This process refers to the ability to access information (both consciously and unconsciously). Researchers suspect, this merging process occurs when we sleep, to strengthen the nerve connections that make up memory. Researchers also think that certain characteristics of brain waves during the sleep stages are associated with special types of memory formation.
What are the effects of not sleeping well?
After finding out that we need good quality and quantity of sleep, maybe you will wonder, what is the impact of lack of sleep.
1. Sleep deprivation can reduce your thinking process
Scientists who examined the effects of sleep deprivation, cited by webMD, found that lack of sleep can lead to decreased alertness and concentration. When you lack sleep, you may find it difficult to focus and pay attention, so you will easily feel confused. The mechanism is not yet known, but it can prevent you from doing tasks that require complex reasoning or thinking skills.
Also, when you are drowsy, your assessment of something will also decrease. Making decisions is more difficult because you are not able to analyze the situation and find it difficult to have the right behavior.
2. Excessive sleep deprivation can weaken your memory
As explained above, nerve connections can make your memory strengthen during your sleep. The stages during which you sleep play a different role in combining new information into our memory. If your sleep is cut off, it is clear that this will disrupt the stages of combining information. When you are sleepy, you will usually forget and put something wrong.
Poor sleep can make it difficult for you to learn. When you have enough sleep quality, you will be easier to retrieve information, so you can learn efficiently. In children, lack of sleep can cause hyperactivity. The effect, having good quality sleep in adolescents can make it more focused, smart, and have a memory capacity to show good performance in school.
What is the danger of not sleeping well?
Sleep deprivation can reduce your time to react; like when doing activities that require high focus such as driving and doing work that requires rapid response. In addition, lack of sleep also has an impact on mental health, as your mood will be clearly disturbed.
Disorders mood, memory, and other functions can cause poor quality of life. Of course, in the long run, this can affect your work and social relationships. Even severe lack of sleep can increase the risk of depression. In addition to depression, in patients with bipolar disorder it is found that 69% to 99% of patients experience sleep disorders in the manic stage (stages in bipolar disorder that refer to conditions of happy overload). Sleep deprivation can trigger this stage. Anxiety disorders can also appear in people who lack the quality of sleep. When you are anxious, you will find it hard to think clearly.
How do you know if your sleep quality is bad?
You are sleepy when you wake up, it's a sign that you still lack sleep. You should feel energetic all day long. When bedtime arrives, the energy slowly decreases. How to find out is to find the signs mentioned above. However, difficulty concentrating can also be triggered by what you are thinking, such as when you are having a problem. Try asking yourself, where is your current focus, attention and concentration?
