Insomnia: causes, symptoms, and what can help

What is insomnia?

Insomnia occurs when an individual struggles to fall asleep, remain asleep, or wakes up too early at least three times a week or more. As a result, they may experience daytime difficulties such as fatigue, problems with concentration, irritability, or reduced ability to function.

It is not solely about the night-time. It also impacts how a person feels and performs during the day. For this reason, doctors take into account not only the lack of sleep itself but also its effects.

When does poor sleep become more than a temporary issue?

Poor sleep is no longer just a temporary issue when it becomes recurrent and starts to impact daily life. Experiencing a few restless nights due to stress, tension, or illness is quite common. However, this does not necessarily indicate insomnia.

The problem becomes more concerning when someone struggles with poor sleep several times a week and begins to feel discomfort or difficulties during the day as a result. In cases of short-term insomnia, there is often an identifiable cause, such as stress, pain, or a significant life event. When the symptoms persist over a longer period, factors that sustain the problem often come into play.

What are the symptoms of insomnia?

Insomnia can present itself in different ways. The symptoms vary from person to person and may be noticeable both at night and during the day.

At night:

• difficulty falling asleep
• waking up frequently during the night
• waking up early and being unable to get back to sleep

During the day:

• fatigue
• reduced concentration
• irritability or being more easily annoyed
• feelings of sadness or tension
• Some individuals may also find that they are less effective in their daily activities, whether at home or work.

What are common causes of insomnia?

Insomnia often does not have a single, clear cause. Typically, multiple factors contribute at the same time. Stress is a well-known cause, but physical ailments, psychological issues, medication, and lifestyle habits can also interfere with sleep.

Sometimes, it begins with a temporary trigger, but the problem continues because the individual alters their sleeping habits, becomes more anxious, or attempts to control their sleep. This can lead to a vicious cycle.

Psychological and emotional factors in insomnia

Stress, worry, tension, anxiety, and sadness often have a significant impact on sleep. Individuals who go to bed feeling tense typically find it more challenging to fall asleep. Furthermore, the body may remain in a heightened state of alertness, making it easier for a person to wake up during the night.

In instances of prolonged stress, sleep may gradually become linked with feelings of restlessness. The bed, rather than being a place of relaxation, can instead turn into a space where frustration and tension accumulate.

Physical and practical factors in insomnia

Physical and practical factors can contribute to or exacerbate insomnia. Pain, shortness of breath, hormonal changes, medication, alcohol, caffeine, and an irregular day-night rhythm are often significant contributors.

Moreover, evening work, late-night screen use, and irregular sleep patterns can interfere with the natural sleep cycle. This can make it harder to fall asleep and result in lighter, less restorative sleep.

Factors that perpetuate insomnia

Insomnia can sometimes become self-perpetuating. For instance, going to bed earlier to make up for lost sleep, taking daytime naps, sleeping in, or lying awake in bed for extended periods can all reinforce the problem. While these responses are understandable, they are often counterproductive.

Negative thoughts about sleep can also intensify the issue. Those who worry about sleeping poorly again often experience heightened tension as bedtime approaches. This tension can make it even more difficult to fall asleep. For more detailed information, read the article Sleep problems: what really works?

What can help with insomnia?

For insomnia, simple changes can often make a difference, particularly if the symptoms have not been present for long. Regularity is key. Maintaining a consistent wake-up time is often more effective than going to bed earlier and earlier.

What can help?

Establishing a consistent routine and creating a calm environment around bedtime can significantly improve sleep.

During the day:

• go to bed and wake up at roughly the same time every day
• ensure you engage in sufficient physical activity and spend time in natural daylight
• limit caffeine consumption later in the day
• avoid using alcohol as a way to fall asleep

In the evening and at night:

• incorporate relaxation into your evening routine
• keep the bedroom quiet, dark, and comfortable
• try relaxation or breathing exercises
• avoid lying awake in bed for extended periods

Relaxation during both the day and evening can also be beneficial. Consider adopting a calming evening routine, reducing exposure to stimulating activities, and setting aside intentional moments for relaxation. Additionally, you can explore our tips for creating a better sleep routine. However, self-help strategies may not always suffice. For persistent symptoms, general sleep advice is often not enough, and further support may be necessary.

What treatments are available for persistent insomnia?

For persistent insomnia, targeted treatment is often more effective than general tips. The preferred approach is typically cognitive behavioural therapy for insomnia, known as CBT-I. This therapy focuses on addressing the thoughts and behaviours that sustain the condition.

CBT-I may include various components, such as stimulus control, sleep restriction, and relaxation exercises.

Stimulus control

Stimulus control aims to re-establish the connection between the bed and sleep. This involves only going to bed when genuinely sleepy, avoiding prolonged periods of wakefulness in bed, and waking up at a consistent time.

This method helps break the association between the bed and frustration, allowing the bedroom to once again become a place of rest.

Sleep restriction

Sleep restriction temporarily reduces the amount of time spent in bed. While this may seem counterintuitive, it can increase sleep pressure, helping individuals fall asleep more quickly and spend a greater proportion of their time in bed actually sleeping.

This approach requires professional guidance and a clear explanation, as it may initially lead to increased fatigue.

Sleep medication

Sleep medication plays a limited role in managing insomnia. Doctors generally avoid prescribing sleeping pills as a standard solution, as they often fail to provide a lasting resolution and come with potential drawbacks.

In some cases, sleeping pills may offer short-term relief for acute, severe sleep difficulties with a clear underlying cause. However, long-term use is typically discouraged due to side effects such as daytime drowsiness, reduced alertness, memory issues, and an increased risk of falls.

When is it advisable to seek help?

It is advisable to seek help if insomnia persists or begins to interfere with daily functioning. This is particularly important if someone experiences significant fatigue, struggles with concentration, or faces mood-related issues during the day.

Medical evaluation is also recommended if:

• the insomnia has been ongoing for an extended period
• self-help measures have proven insufficient
• pain, psychological issues, or medication may be contributing factors
• there are signs of another sleep disorder
• safety is at risk, such as when driving or at work

A doctor can help identify the underlying cause and recommend the most appropriate treatment.

Conclusion

Insomnia is more than just a few sleepless nights. It involves recurring sleep difficulties that also affect daytime functioning. The causes can vary from person to person, often involving multiple contributing factors. For this reason, it is important to consider not only night-time habits but also stress and other influences that may exacerbate the symptoms.

Do the symptoms keep returning, or is it proving difficult to improve your sleep? It may be helpful to explore the underlying causes and potential solutions.
