Short-Term Insomnia vs Chronic Insomnia Explained

Short-term insomnia or sleeplessness lasts from one night up to a few weeks, often caused by anxiety or environmental changes. Chronic insomnia persists for at least three nights a week for three months or more. It may be a primary health problem or a symptom of another root cause, such as medications, medical issues, or other sleep disorders.

Insomnia means you are persistently facing sleep problems. It is a common sleep disorder. People with insomnia may experience trouble falling asleep, staying asleep, or getting good quality sleep. It happens even if you have the time and the right environment to sleep well. Insomnia can mitigate your ability to perform daily activities and may make you feel sleepy during the day. 

Changes in your schedule or environment may cause short-term insomnia. It can last for a few days or weeks. Chronic (long-term) insomnia happens 3 or more nights a week, continues for more than 3 months, and cannot be fully explained by another health problem. This blog explains the differences between short-term and long-term insomnia and how to avoid it with UK sleeping pills and healthy sleep habits.

Acute Or Short-Term Insomnia

Duration: It continues from one night to a few weeks.

Causes: It is generally caused by specific stressors, such as family issues, work pressure, or a traumatic event. Changes in environment or schedule, like travel or a new baby, can also cause sleeplessness.

Nature: It often goes away by itself once the underlying factor is removed.

Long-Term Or Chronic Insomnia

Duration: It continues from three nights a week to three months or longer.

Causes: It may be a primary problem with an unknown cause, or more often, a secondary issue caused by another health issue.

Secondary Causes: Psychiatric conditions (e.g., anxiety, depression), medical conditions (e.g., pulmonary disease or chronic pain), or medication side effects. Substances like alcohol, caffeine, and tobacco can also lead to chronic insomnia.

Worsening Factors: Behaviours formed during the acute stage can prolong the problem even after the initial cause no longer exists.

Nature: Sleep apnea and chronic insomnia often occur together, as breathing pauses during sleep can repeatedly wake the body and disturb the natural sleep cycle. It needs more in-depth treatment, often starting with behavioural therapies like Cognitive Behavioural Therapy for Insomnia (CBT-I)

How to Avoid Insomnia?

Not all people experiencing trouble falling asleep have insomnia. It is crucial to have good sleep hygiene to avoid insomnia.

Bedtime: Sleep follows a particular sleep pattern, which can cause sleep disturbances if we break it. It’s why it is important to go to bed at more or less the same time every day, because if you go to sleep earlier, the body does not identify that it is your bedtime, and it will become hard to fall asleep.

Wake-up Time: Be aware that the time we get up determines the time we will fall asleep later on.

Daytime Napping: A person with insomnia is not recommended to take naps during the day, as it can provoke their nocturnal insomnia.

Diet: It is not advised to go to bed hungry or on an overly full stomach. Mood-boosting drinks, such as coffee or caffeinated tea, should not be taken in the afternoon, as a general rule, and insomniacs should try to avoid them.

Exercise: Exercising throughout the day can cause beneficial fatigue, but you should avoid exercising in the late afternoon.

Ritual: Performing a number of small steps before bedtime, such as putting on pyjamas, brushing teeth, brushing hair, or taking a bath, can prepare the body for bedtime.

The most essential thing for a person is to relax before bed. There is no point in trying to fall asleep when you are stimulated or full of energy, so relaxation measures can help induce sleep. If the insomniac still cannot fall asleep, it is preferable to get out of bed, take long breaths, and wait for sleep, instead of staying in bed.
