What Is Insomnia?

What is Insomnia? Sleep is an essential biological necessity for body health, brain function, and emotional well-being. But millions around the globe suffer from insomnia and sleep disorders, which are characterized by a persistent struggle to fall, remain, or get a restorative state of sleep.

Sleep disorders affect between 10 and 30% of the adult population, with the most severe affecting daily activities, productivity, and living. The comprehensive guide to insomnia explores the issue deeply, providing forms, causes, symptoms, diagnostic options, treatments, and strategies for prevention.

Tossing and Turning All Night? Understanding Insomnia

It’s that familiar feeling of lying in bed, gazing at the ceiling, and counting the days until sunrise. It could be that your mind isn’t shutting off, or you wake up at 3 a.m. and cannot fall asleep. It’s not just an unlucky evening; it could be a sign of sleepiness.

The term “insomnia” means that you constantly struggle to get sleep, even when you can. Sleepy people take longer before falling into a deep sleep. Some wake up early and are unable to return to bed. Some toss and turn throughout the night but never get uneasy sleep.

It’s not about feeling tired following a rough night. The real cause of insomnia is that it can take many months or weeks. It can drain your energy and make you unhappy; it can also affect the health of your body.

Definition of Insomnia

Sleepiness is defined as the continuous difficulty with establishing and maintaining a steady sleep, even though one can sleep at a sufficient rate, and causes impairment during the daytime. It is a condition that can be characterized as affecting the quality of life. Diagnostic and Statistical Manual of Mental Disorders (DSM-5) as well as the International Classification of Sleep Disorders (ICSD-3) define insomnia based on:

Trouble falling asleep (sleep at the beginning of insomnia)
Trouble falling asleep (sleep maintenance insomnia)
Too early to get up (early dawn)
Sleep that is not regenerative (poor quality of sleep)

To be considered a clinical diagnosis, the symptoms must occur at least three times every week for at least three months and create significant stress or impairment.
