Advice for Insomnia
Insomnia is a prevalent sleep disorder that affects millions of people worldwide. It is characterized by persistent difficulty in falling asleep, maintaining sleep, or experiencing restorative sleep, despite having the opportunity to sleep. People with insomnia often wake up feeling unrefreshed, which can lead to significant impairments in daily functioning and quality of life.
There are two main types of insomnia: acute and chronic. Acute insomnia is short-term and often triggered by stressful life events, such as job loss, illness, or the death of a loved one. It typically lasts for a few days to a few weeks. Chronic insomnia, on the other hand, occurs at least three nights a week for three months or longer and can be caused by a variety of factors, including medical conditions, mental health disorders, medications, and lifestyle habits.
Insomnia can also be classified as primary and secondary insomnia. If you have primary insomnia, it’s caused by a lack of melatonin (sleep hormone) and isn’t linked to any other health condition or illness, or medication. Secondary insomnia is when there’s another physical health factor responsible for your lack of sleep. If you have trouble sleeping because you drink a lot of alcohol late at night, for example, this is secondary insomnia. But if you have trouble sleeping due to stress, sensitivity to lights or noises, or changes in your sleep schedule, this is primary insomnia.
Insomnia can last for one night, or go on for months or years. The longer you live with insomnia, untreated, the more likely you are to develop secondary problems, like depression or cardiovascular illness.
Insomnia can be diagnosed through a conversation with a clinician about your sleep habits. Factors like age, your lifestyle, how long the insomnia has been going on for and existing health issues will help the clinician to make a diagnosis and suggest the best form of treatment. Sometimes you might be asked to keep a sleep diary too. It’s not common, but if your doctor thinks there may be a problem that needs to be looked at by a specialist, on some occasions you’ll be referred to a sleep centre for tests. For some sleep related conditions, a specialist might need to observe you sleeping in a controlled environment.
Insomnia is characterized by difficulty falling asleep, staying asleep, or waking up too early and not being able to go back to sleep. The symptoms can vary in intensity and duration but generally include the following:
Primary Symptoms

Insomnia, a common sleep disorder, can be caused by a wide range of factors. These can be broadly categorized into psychological, physiological, environmental, and lifestyle-related causes. Here is a detailed look at the various causes of insomnia:
Psychological Causes
- 1. Stress: Chronic stress about work, school, health, finances, or family can keep your mind active at night, making it difficult to sleep.
- 2. Anxiety: Anxiety disorders, including generalized anxiety disorder, panic disorder, and post-traumatic stress disorder (PTSD), can lead to insomnia.
- 3. Depression: People with depression often experience disrupted sleep. Insomnia can also exacerbate depressive symptoms.
- 4. Emotional Distress: Grief, trauma, and other significant emotional events can trigger insomnia.
Physiological Causes
1. Medical Conditions:
- Chronic Pain: Conditions like arthritis, fibromyalgia, and back pain can make it difficult to get comfortable and stay asleep.
- Respiratory Issues: Asthma, chronic obstructive pulmonary disease (COPD), and sleep apnea can disrupt breathing during sleep.
- Cardiovascular Disease: Heart conditions, such as heart failure and angina, can affect sleep.
- Neurological Disorders: Parkinson’s disease, Alzheimer’s disease, and other neurodegenerative disorders can disrupt sleep patterns.
- Gastrointestinal Issues: Acid reflux, ulcers, and irritable bowel syndrome (IBS) can cause discomfort that interrupts sleep.
2. Hormonal Changes:
- Menopause: Hot flashes and night sweats during menopause can cause insomnia.
- Pregnancy: Hormonal changes and physical discomfort can lead to sleep disturbances.
- Thyroid Disorders: Hyperthyroidism can cause sleep difficulties.
3. Sleep Disorders:
Other sleep disorders, such as restless legs syndrome (RLS) and periodic limb movement disorder (PLMD), can interfere with sleep.
Environmental Causes
- Noise: Loud or disruptive noises can prevent you from falling asleep or staying asleep.
- Light: Exposure to light, particularly blue light from screens, can interfere with the body's sleep-wake cycle.
- Temperature: An uncomfortable room temperature, whether too hot or too cold, can disrupt sleep.
- Bedding: Uncomfortable mattresses, pillows, and bedding can cause discomfort and disrupt sleep.
Lifestyle-Related Causes
1. Irregular Sleep Schedule: Inconsistent sleep times, such as those caused by shift work or travel across time zones (jet lag), can disrupt your circadian rhythm.
2. Poor Sleep Habits:
- Stimulating Activities Before Bed: Engaging in stimulating activities, such as watching TV, using electronic devices, or exercising, can make it difficult to wind down.
- Poor Sleep Environment: An uncomfortable sleep environment, including a noisy, bright, or cluttered bedroom, can affect sleep quality.
3. Dietary Factors:
- Caffeine: Consuming caffeine, especially in the afternoon or evening, can interfere with falling asleep.
- Nicotine: Nicotine is a stimulant that can disrupt sleep.
- Alcohol: While alcohol might help you fall asleep, it can interfere with deep sleep stages and cause you to wake up during the night.
4. Medication and Substance Use:
- Medications: Certain medications, such as antidepressants, asthma medications, blood pressure medications, and some over-the-counter medications, can cause insomnia as a side effect.
- Substance Abuse: The use of recreational drugs can disrupt sleep patterns.
Other Causes
- 1. Age: Insomnia becomes more common with age. Changes in sleep patterns and health conditions can contribute to insomnia in older adults.
- 2. Genetics: A family history of insomnia can increase the likelihood of experiencing sleep disturbances.
- 3. Mental Health Conditions: Other mental health conditions, such as bipolar disorder and schizophrenia, can cause insomnia.
Interaction of Multiple Factors
Often, insomnia is caused by a combination of factors rather than a single cause. For example, someone with a high-stress job may also have poor sleep habits and a medical condition that together contribute to insomnia.
At Pharmacinta, we provide Circadin which is a licensed treatment for primary insomnia in people over the age of 55. It contains melatonin, the sleep hormone, which helps the body to shut down when it’s time to sleep. The same medication is also sometimes sold ‘off label’ as a treatment for jet lag.
Circadin uses synthetic melatonin to treat primary insomnia. Melatonin is a hormone that is produced in your body to influence healthy sleep patterns. It’s usually produced in your body at night to help you settle down enough to fall asleep.
We only supply Melatonin tablets to treat short-term sleep problems in people aged 55 and over. Sometimes, sleep specialists might prescribe Melatonin to help with longer-term sleep problems in children and adults.
Insomnia can be treated through a variety of methods, depending on the underlying causes and individual patient needs. Besides melatonin, there are several other alternative treatments ranging from lifestyle changes to cognitive behavioral therapies and herbal supplements. Here are some notable alternatives:
