What Is Insomnia?
We all have those nights where sleep seems somewhat impossible to achieve. Occasional sleep deprivation is normal and often subsides after a day or two. However, there are some instances where the deprivation lasts for weeks, months or even years. In this case, this common symptom of life’s challenges transforms into a disorder known as insomnia.
So, what is insomnia in more scientific terms? It is a complex condition that involves the rapid decline of sleep quality, duration, sleep onset times and more. Most people refer to the condition as a sleep disruption, because it causes disruptions to the sleep cycle, making it difficult for patients to fall and stay asleep.
This sleeping disorder can have a devastating impact on the sufferer’s mental and physical health. Statistics show that sleep disorders affects approximately 30–40% of the world’s population.

- Waking up prematurely every morning
- Difficulty focusing your thoughts during the day

Different Types of Insomnia Explained
Sleep disruption is divided into several categories, which each have a different root cause. The primary types being short and long-term sleep disruption, more commonly known as acute and chronic insomnia.
The acute form of the disorder involves brief periods of sleeplessness or sleep issues that last a maximum of 3 months or less. The chronic form of the disorder is the complete opposite as it involves periods of sleeplessness that lasts for extended periods that stretch well beyond 3 months.
Secondary types of the disorder include sleep onset, which is characterised by a patient’s inability to initiate sleep. This is a common issue that is often linked to daytime sleepiness. A person with this type of disorder takes longer than 30 minutes to fall asleep.
Recurrent nocturnal awakenings that cause patients to wake up earlier than they intend to is called sleep maintenance disruption. The incomplete sleep patterns associated with this disorder commonly cause excessive daytime sleepiness and daytime fatigue.
Comorbid sleep disruptions involve cases where sleep issues occur along with mental or physical conditions. This results in situations where one condition aggravates the other. Although each type of sleep disorder is characteristically different, the solution remains the same. Most patients choose to use sleeping tablets to manage and control symptoms and reinstate healthy sleep patterns, duration and quality.
