What is Insomnia - Diagnosis and Treatments

What is Insomnia?

Insomnia is a sleep disorder that makes it difficult for individuals to fall asleep, stay asleep, or wake up feeling rested. People with insomnia may experience difficulty falling asleep, waking up frequently during the night, or waking up too early in the morning and not being able to fall back asleep.

Insomnia can be a short-term issue, lasting only a few days or weeks, or it can be a chronic problem, lasting for months or even years. It can affect anyone at any age, but it is more common in adults and tends to be more prevalent in women than men.

Insomnia can be caused by a variety of factors, including stress, anxiety, depression, certain medical conditions, medications, and poor sleep habits. When left untreated, insomnia can lead to fatigue, irritability, difficulty concentrating, and other health problems.

Causes of Insomnia

Insomnia can be caused by a variety of factors, both physical and psychological.

Medical Conditions

Certain medical conditions, such as chronic pain, respiratory problems, and neurological disorders, can make it difficult to fall or stay asleep.


Certain medications, such as antidepressants, antihistamines, and stimulants, can interfere with sleep patterns and cause insomnia.

Mental Health Disorders

Anxiety, depression, and post-traumatic stress disorder (PTSD) are some mental health conditions that can disrupt sleep and cause insomnia.

In addition to these common causes, insomnia can also be caused by environmental factors, such as noise, temperature, or an uncomfortable sleeping environment.

Understanding the underlying cause of insomnia is essential to developing an effective treatment plan.

Diagnosis of Insomnia

Diagnosing insomnia typically involves a physical exam, a review of your sleep history, and an evaluation of your sleep habits. Your doctor may also ask you to keep a sleep diary for a period of time to track your sleep patterns and identify any potential underlying causes of your insomnia.

In addition to a sleep diary, your healthcare provider may also recommend one or more of the following tests to help diagnose insomnia

Polysomnography (Sleep Study)

A polysomnography test involves spending a night in a sleep laboratory where your sleep patterns are monitored using electrodes attached to your scalp, face, and other parts of your body. This test can help identify any underlying sleep disorders that may be contributing to your insomnia.


An actigraphy test involves wearing a wristwatch-like device that tracks your movements and sleep patterns over a period of several days. This test can help identify any disruptions to your sleep-wake cycle and assess the effectiveness of any treatments you may be undergoing.

Once a diagnosis of insomnia has been made, your doctor can work with you to develop an appropriate treatment plan. By addressing the underlying causes of your insomnia, you can improve your sleep quality and overall well-being.

Treatment of Insomnia

Treating insomnia typically involves a combination of lifestyle changes, behavioral interventions, and medication.

Cognitive Behavioral Therapy for Insomnia (CBT-I)

This therapy focuses on identifying and changing negative thoughts and behaviors that may be contributing to your insomnia. CBT-I can be conducted individually or in a group setting and is considered the most effective treatment for chronic insomnia.

Medications for Insomnia

Certain medications, such as benzodiazepines and non-benzodiazepine hypnotics, can be used to treat insomnia. However, these medications should be used with caution and under the guidance of a doctor due to potential side effects and the risk of dependence.

Alternative Therapies for Insomnia

Alternative therapies, such as acupuncture, hypnotherapy, and melatonin supplements, may also be helpful in managing insomnia. However, more research is needed to determine their effectiveness and safety.

In addition to these treatments, making lifestyle changes can also help improve sleep hygiene and manage insomnia.

Tips for Improving Sleep Hygiene

Sleep hygiene refers to the habits and behaviors that can promote healthy sleep. Improving sleep hygiene can help manage insomnia and improve overall sleep quality.

Establish a Regular Sleep Schedule

Try to go to bed and wake up at the same time every day, even on weekends. This can help regulate your sleep-wake cycle and improve your overall sleep quality.

Create a Sleep-Friendly Environment

Keep your bedroom quiet, cool, and dark. Use comfortable bedding and a supportive mattress. Remove any distractions, such as electronic devices or a television, from your bedroom.

Practice Relaxation Techniques

Try deep breathing, meditation, or progressive muscle relaxation to help calm your mind and body before bed. This can help you fall asleep more easily and improve your sleep quality.

Avoid Stimulants

Avoid caffeine, alcohol, and nicotine in the evening, as they can interfere with sleep. Try drinking herbal tea or warm milk instead of caffeinated beverages.

Limit Screen Time

Exposure to the blue light emitted by electronic devices, such as smartphones, tablets, and computers, can interfere with sleep. Try to avoid using these devices for at least an hour before bed.

Get Regular Exercise

Regular exercise can improve overall sleep quality and help manage insomnia. However, try to avoid exercising too close to bedtime, as it can make it difficult to fall asleep.

By incorporating these tips into your daily routine, you can improve your sleep hygiene and enjoy a more restful night’s sleep.
