What Is the Science Behind Insomnia?

What Is the Science Behind Insomnia ?

Have you ever suffered from insomnia? In other words, do you face the difficulty of falling asleep and staying asleep at night? Let’s find out the science behind insomnia!

Scientific discoveries about insomnia have shown that your brain actually has two systems. One helps you sleep; the other helps keep you awake. The wake system sends out signals that put your brain into an alert, or more active, state. This helps you wake up in the morning and stay awake during the day. The sleep system sends signals that help you fall and stay asleep at night. The feeling of being trapped between wake and sleep has more science behind it than you may think.

Often times, insomnia is caused by multiple reasons, such as not enough rest, hunger, psychological trauma and so on. No matter what the reason is, millions of human beings suffer from the devil called insomnia. It robs you from getting enough rest, saps your energy and destroys your productivity the next day. Not to mention the detrimental effect towards your own physical and mental health.

What is Insomnia?



Insomnia by definition is the difficulty of falling asleep and staying asleep. It refers to the types of restlessness a person suffers at different points of his or her sleep cycle. A simple indication to diagnose insomnia is when a person is not satisfied with the amount of sleep that he or she has been getting.


The Two Types of Insomnia

  1. Acute Insomnia

    There are two main types of insomnia. The first type is the kind of insomnia when you only suffer a couple of restless nights. Often times, you’re able to fall asleep and stay asleep quickly. For many, they might not think that they have insomnia but the fact is, they could be having Acute Insomnia.
    So what is Acute Insomnia? This kind of insomnia comes from the core levels of stress that insomniacs are experiencing at that moment. They will face a short period where they are not able to fall asleep because of the life circumstances they’re facing at that moment. This type of insomnia doesn’t last for a prolonged time. Instead, it only happens due to certain factors or events during a specified period of time.

  2. Chronic Insomnia

    The second type of insomnia is known as Chronic Insomnia. It is a prolonged kind of insomnia where a person fails to get any sleep for a few nights every week for 2-3 months or more. Usually, this occurs when he’s facing a significant change in his environment, physically or mentally. It could be moving to a new home, losing a loved one, being in a new workplace, facing challenges in school, or having trouble adapting to a harsher weather. Perhaps, the reason why they’re having trouble with sleep is that they have an unhealthy sleep habit without a proper sleep routine.


The Causes of Insomnia


Regardless of the types of insomnia, the causes are the same. The difference lies in the intensity of emotions a person experiences for a set amount of time. Besides that, underlying medical conditions can also cause insomnia. The stress on the patient’s body will cause the mind to stay awake for a longer period of time. Physical pain can also cause insomnia as the body cannot get into a comfortable position to rest.

The Risk Factors Insomnia



The risk factors of insomnia include being a female, being pregnant or in the period of menopause, an older adult above the age of forty, suffering from more stress, suffering from depression, have a night time job, travel long distances where there is a time change, or have a family history of insomnia. All of these factors lead a person closer to insomnia. But do you realize that most of these risk factors are the results of your choices? In most cases, people think that they have little to no choice in life, which is not true.

  1. My series on how I overcame insomnia after suffering with it for a year and a half has been pretty popular. I suffered that long with it while I made research backed lifestyle interventions little by little to overcome it. I’ve noticed that if I deviate from these too long it comes back, if I stick to these I sleep through the night. My post on overcoming insomnia is here https://donovancarper.com/index.php/2020/02/08/my-insomnia-experience-part-3-sleeping-naturally-at-last/
