What is insomnia? Everything you need to know
Insomnia is a sleep disorder that makes it difficult to fall asleep or stay asleep. If a person has insomnia, they may also wake up too early and not be able to get back to sleep.
Generally, adults need at least 7 to 9 hours of sleep in every 24-hour period, depending on their age. Getting sufficient sleep is vital for maintaining good mental and physical health. However, insomnia is a common sleep problem that can disrupt how much sleep a person gets.
When insomnia lasts for up to a few weeks, a health expert may refer to it as acute insomnia. When it lasts for 3 months or longer, it is known as chronic insomnia. Short-term insomnia can lead to daytime fatigue, difficulty concentrating, and other problems. In the long term, it may increase the risk of various diseases.
What does it mean to be ‘an insomniac’?
Insomnia is the most common sleep complaint. A person with insomnia has difficulty falling asleep or staying asleep. They may consistently wake up too early. Sleep deprivation can lead to issues such as:
- daytime sleepiness and lethargy
- a general feeling of being mentally and physically unwell
- mood changes, irritability, and anxiety
Also, the issues above can contribute to insomnia — they may be causes, effects, or both.
In addition, insomnia may play a role in the development of:
- obesity
- anxiety
- accidents and injury
It can also undermine school and work performance and limit a person’s ability to do daily activities.
Causes of insomnia
Insomnia can result from a range of physical and psychological factors. Often, the cause is a temporary problem, such as short-term stress. In some other instances, insomnia stems from an underlying medical condition.
Common causes include:
- having jet lag, switching shifts at work, or dealing with any other changes to the body’s internal clock
- the room being too hot, cold, or noisy, or the bed being uncomfortable
- caring for someone in the house, if it disrupts sleep
- getting too little physical exercise
- having night terrors or bad dreams
- using recreational drugs, such as cocaine or ecstasy
In some people, stress or a mental health issue is responsible for insomnia. A person may be experiencing:
- depression
- anxiety
- bipolar disorder
- schizophrenia
Some other health conditions that can limit sleep include:
- an overactive thyroid
- sleep apnea
- chronic obstructive pulmonary disease (COPD)
- chronic pain
- Alzheimer’s disease
In rare cases, some people may inherit a condition known as fatal familial insomnia. This genetic condition can cause sleep problems and brain damage that eventually lead to death.
