What Is The Definition Of Insomnia?

Insomnia is a condition in which you are not getting enough sleep. This could mean you’re not getting enough sleep, not sleeping well, or having trouble falling asleep or staying asleep. For some people, insomnia is a minor inconvenience. For some people, insomnia can be a big problem.

The reasons for the occurrence of insomnia are similarly varied. Your body needs sleep for a variety of reasons, but science is still figuring out why sleep is so important for your body. Experts know that not getting enough sleep can lead to sleep deprivation. Sleep deprivation is usually uncomfortable and prevents optimal functioning.

Types of Insomnia

There are two main ways that experts classify insomnia into categories:

Time: Experts classify insomnia as acute (short-term) or chronic (long-term). The chronic form is called insomnia disorder.

Cause: Primary insomnia means that it occurs naturally. Secondary insomnia means that it is a symptom of another symptom or condition.

How Common Is Insomnia?

Both acute and chronic forms of insomnia are very common. Approximately 1 in 3 adults worldwide experience symptoms of insomnia, and approximately 10% of adults meet the criteria for insomnia.

What Are The Symptoms Of Insomnia?

Insomnia has several potential symptoms that fall into several categories.

1. If you have trouble sleeping.

2. Daytime effects such as feeling tired, feeling unwell or sleepy, slowed reaction times, and difficulty remembering.

3. Characteristics of chronic insomnia.

What Causes The Disease?

Experts do not know exactly why insomnia occurs, but based on current knowledge, there are many possible contributing factors to this condition. Some of these factors may be causative or  simply contributing. More research is needed to understand exactly how and why insomnia occurs.

Factors include, but are not limited to:

Family History (Genetics): Sleep characteristics and disorders, including insomnia, appear to be inherited in families.

Differences In Brain Activity: People with insomnia may have more active brains or have differences in brain chemistry that affect their ability to sleep.

Medical Conditions: Your physical health can affect your ability to sleep. These include temporary illnesses such as minor infections or injuries, or chronic conditions such as acid reflux or Parkinson’s disease. Medical conditions that affect circadian rhythms, the body’s natural sleep-wake clock, can also be a factor.


Mental Illness: About half of people with chronic insomnia also suffer from at least one other mental illness, such as anxiety or depression.

Your Habits and Routines: Your sleep habits (also known as sleep hygiene) can contribute to insomnia. This includes whether and when you take naps, when you go to bed, whether and when you consume caffeine, and other habits.

How Is Insomnia Treated?

Is there a cure? There are many ways to treat insomnia, from simple lifestyle and habit changes to various medications.

The main approaches to treating insomnia are:

1. Develop and practice good sleep habits (also known as sleep hygiene).

2. Medicines that help you fall asleep or stay asleep, especially non-addictive medicines, or medicines that can affect your sleep.


3. Mental health care.

Medications That Help You Fall Asleep And Stay Asleep

Many different types of medications can help you fall asleep and stay asleep. Many of these are sedatives and hypnotics, both prescription and nonprescription, as well as mental health medications and certain herbs and supplements.

Sedatives: The names of these drugs are derived from the Latin word meaning “to calm down.” They reduce the activity of the nervous system.

Hypnosis: These names are derived from  the Greek god of sleep, Hypnos. These make you sleepy.


Insomnia is usually not a big problem. Most people who suffer from insomnia feel tired or not feeling their best the next day, but this feeling can often improve if you get enough quality sleep. Chronic insomnia is devastating. Although it is not usually  dangerous, it can still negatively impact your life in many ways. If you notice  symptoms of sleep deprivation, we recommend that you consult your doctor.
