Insomnia: The Sleep Disorder That Could Be Killing You

Insomnia is a type of sleep disorder that has been affecting millions of people worldwide; it’s just an inconvenience; it’s a silent threat that can have profound consequences on both our physical and mental health. Studies show that up to 30% of adults experience short-term insomnia, while 10% suffer from chronic insomnia (according to the CDC). Insomnia doesn’t just lead to poor sleep- it can also increase risks of our overall conditions like heart disease, diabetes, and even premature death if we leave it untreated. If you’re struggling to get quality sleep, it’s crucial to understand why insomnia could be a severe threat and how you can combat this life-disrupting disorder.

What is Insomnia?

Insomnia is identified by the difficulty of falling into sleep, waking up early in the morning and not being able to sleep again, or staying asleep.

Insomnia can be Classified into Different Types:

1. Acute insomnia: short-term insomnia that often results from stress, a significant life event, or lifestyle changes. Acute insomnia typically lasts days to weeks.
2. Chronic insomnia: a persistent form of insomnia that occurs at least three nights per week and lasts for three months or longer. Chronic insomnia often requires treatment, as it can severely impact daily functioning and health.

Types of Insomnia: Primary vs. Secondary:

• Primary insomnia is not directly linked to other health conditions or problems. Often, stress or lifestyle factors cause it.
• Secondary Insomnia: This type occurs due to another health issue, such as chronic pain, anxiety, depression, or medication side effects.

Symptoms of Insomnia:

The prime symptom of insomnia is to go beyond merely fighting to fall asleep. Some of the common signs include:

• Difficulty falling asleep: It is the situation in which we face difficulty falling asleep even when tired. An example of secondary insomnia could be experiencing chronic pain from a back injury that will cause trouble falling asleep and staying asleep at night. It takes us to a cycle of poor-quality sleep, exacerbating their pain and affecting their overall health and well-being.
• Waking up frequently during the night. We may wake up several times at night without reason in this situation. Due to interruptions in quality sleep, we feel tired the whole day, which impacts our productivity and mood. Additionally, individuals with insomnia may also experience difficulty concentrating, memory problems, and decreased immune function. When experiencing those types of insomnia symptoms, without delay, we should identify the causes of those symptoms and improve our sleep quality by consulting with a respective expert consult.
• Another common symptom of insomnia is waking up too early in the morning and not being able to fall back asleep. We feel sleepy again when it is time to wake up and jump to our daily work. We start our day by feeling tired, which makes it challenging to contribute to our responsibilities with concentration and memory. We may make a mistake in our personal or professional work, or the outcome may be different than expected. We must seek a professional to improve our sleep quality and maintain our physical and mental well-being. We can also enhance our quality of life by managing these symptoms and adequately caring for ourselves.
• Feeling tired in the morning: Think we feel so exhausted when we are going to start our whole day with lots of work; how will you feel that time? In my case, it will be an unhappy moment. However, we can still manage it by taking proper care of ourselves with the guidance of a professional or by taking proper treatments that are available to manage insomnia. Consulting with a sleep specialist can help us to define the causes and guide us to achieve good quality sleep. With the proper intervention, you can regain control over your sleep patterns and wake up refreshed and rejuvenated each morning. Don’t let insomnia hold you back from living your best life—take the necessary steps to prioritize your sleep health today.
• Irritability: A whole day’s irritability makes our mood swings, which makes it difficult to concentrate on our activities. We can alleviate this symptom with proper treatment and self-care. There is a way to enhance our overall quality of life and well-being by identifying its root causes. Feel free to seek help to change your sleep habits and have a restful sleep over the night you deserve. Remember, a good night means an excellent next day of your life, and a good day means you can move to a brighter, more energized future.
• Daytime drowsiness or excessive sleepiness could indicate insufficient restorative sleep at night. This can affect your productivity and focus during the day and increase your risk for accidents or injuries. We can improve our mood, energy level, and general health by keeping priority sleep hygiene practices. Remember that your body needs adequate sleep to heal and rejuvenate, so don’t undervalue the importance of a quality night’s sleep. You’ll be surprised at how much your body will appreciate it. For example, if a person consistently feels sleepy during the day and struggles to stay alert while driving, they may be at a higher risk of getting into a car accident.

The emotional toll of insomnia can manifest as anxiety, depression, and even cognitive impairments, further affecting an individual’s quality of life.

Causes and Risk Factors

We should find the root causes of insomnia to manage it effectively. Let me share some causes and risk factors here:

1. Stress and Anxiety: Our lives are running very fast in this fast-growing world; sometimes, we forget our work-life balance, leading to a stressful life. Sometimes, we become worried about life’s events, such as financial problems, relationship crises, family crises, or many job-related issues that make us stressed, which leads to insomnia.
2. Lifestyle Factors:
   • Caffeine: Caffeine helps us to awake by interfering with the brain’s natural signaling processes related to sleep. Our brain builds adenosine (a neurotransmitter) throughout the day to promote sleepiness by binding specific adenosine receptors. It is a process that makes a signal for rest. Caffeine works as an adenosine receptor antagonist, which blocks adenosine from binding to its receptors. As a result, the brain doesn’t “sense” the usual level of sleep pressure, helping us feel more awake and alert.
   • Alcohol: It will make it easier to fall asleep initially by inducing relaxation and promoting sleep due to its activities to our brain’s central nervous system depressant, which enhances the activity of gamma-aminobutyric acid (GABA). But later part of the night, alcohol disrupts the sleep architecture. It suppresses rapid eye movement (REM) sleep, a crucial cognitive restoration and memory consolidation stage. It leads to a lighter, less restorative sleep cycle. Our body metabolizes alcohol (typically within 4-5 hours), and after, its sedative effects wear off, leading to rebound wakefulness. It can cause fragmented sleep and difficulty staying asleep.
   • Irregular sleep schedules: Everything on the earth is running with a routine. Even our whole body and its functions are run by a routine. Our lifestyle should have a routine and schedule to maintain our overall well-being. We need to follow a proper sleep schedule for good quality sleep because disruption of the natural sleep and wake cycle leads us to difficulty falling asleep.
3. Medical Conditions: Sometimes, some of our medical conditions may cause insomnia, like chronic pain, asthma, or neurological disorders. It drives us to challenge our sleep behaviors.
4. Mental Health Disorders: Conditions like depression, PTSD, and bipolar disorder often correlate with sleep disturbances.

Additional Risk Factors:

• Age: Our age is also prone to insomnia when we become older due to changes in our circadian rhythms or primary health conditions.
• Gender: Women are more likely to experience insomnia due to hormonal changes, especially during pregnancy, menopause, or menstrual cycles.
• Lifestyle Choices: A sedentary lifestyle or excessive screen time can contribute to poor sleep quality.

The Hidden Dangers of Insomnia

Insomnia doesn’t just cause fatigue; it’s a severe risk factor for several health complications, which can impact both life quality and longevity.

• Heart Disease and High Blood Pressure: Heart disease and high blood pressure are related to insomnia, which may increase the risk of cardiovascular issues. Our cardiovascular system can be failed due to chronic insomnia, which elevates our blood pressure. It can be an expended heart attack or stroke risk.
• Chronic insomnia increases the risk of heart attacks and strokes by elevating our blood pressure.
• Diabetes and Weight Gain: Insufficient sleep can interfere with blood sugar regulation, increasing the likelihood of developing diabetes. We may also gain weight due to sleep disorder, which affects our hormones that regulate appetite, leading to weight gain.
• Weak Immune System: Quality sleep is essential for a healthy immune system. Our immune system can be weakened by the effects of chronic insomnia, which will make our body more susceptible to infections.
• Mental Health Decline: Insomnia can impact our mental health issues, worsening anxiety and depression. It’s also associated with cognitive decline, memory, and concentration problems.

The overall impact of the above factors contributes to a shortened lifespan for individuals who have chronic insomnia, making it imperative to address this sleep disorder.

How Insomnia Affects Daily Life:

Our health risk can extend by the effects of insomnia, which will significantly impact our daily activities and overall living quality of life.

1. Physical Health: A shortage of quality sleep leads us to chronic tiredness, weight gain, and a weakened immune system, which makes us vulnerable to illness; we feel lower energy levels than we need for our daily tasks.
2. Mental Health: Insomnia contributes to “brain fog,” reducing focus, memory, and cognitive sharpness, which can hinder productivity and performance at work or school.
3. Relationships and Social Interactions: Insomnia can worsen our relationships or social interactions. Not getting enough sleep can make us grumpy and change our mood, which can hurt our relationships with friends, family, and coworkers.

Diagnosis and When to See a Doctor?

Insomnia diagnosis begins with a review of sleep patterns, lifestyle habits, and any existing health issues. Standard assessment tools include:

• Sleep Diaries: Tracking sleep patterns and habits over several weeks can help identify triggers and patterns associated with insomnia.
• Questionnaires: Self-report questionnaires assess the severity and impact of sleep difficulties.
• Sleep Studies: In cases where a sleep disorder like sleep apnea is suspected, a sleep study can provide insights into sleep quality and disturbances.

We have to seek professional help when it has been noticed that insomnia persists for a few weeks or is in our daily activities.

Treatment Options for Insomnia:

Lifestyle Changes and Sleep Hygiene:

Improving sleep hygiene involves making changes to sleep habits and the sleep environment, such as:

• Establishing a consistent sleep schedule helps to develop an internal body-clocking system that allows us to maintain healthy sleep.
• Reducing screen time before bed, as blue light from devices can disrupt sleep
• Creating a comfortable sleep environment by adjusting room temperature, reducing noise, and ensuring proper lighting

Behavioral Therapies:

CBT-I (Cognitive Behavioral Therapy for Insomnia): CBT-I is one of the most common and effective treatments. Addressing negative thoughts and behaviors that contribute to insomnia will be replaced with positive ones by CBT-I. These techniques often include:

• Relaxation exercises to reduce anxiety.
• Sleep restriction therapy to establish a consistent sleep schedule.
• Stimulus control helps you connect your bed with sleeping, not staying awake. For example:
  • Only use your bed for sleep (and intimacy), not for watching TV, reading, or worrying.
  • Go to bed only when you feel sleepy.
  • When you can’t sleep after 20 minutes, get up and relax until you feel tired again.
  • Wake up at the same time every day, even on weekends.

These habits train your mind to see the bed as a place for rest, making it easier to fall asleep.

Medications and Supplements:

• Prescription Medications: Doctors may prescribe sedatives or other sleep aids for short-term use, but these often come with side effects and the risk of dependence.
• Over-the-counter Options: Antihistamines and melatonin are standard OTC options, although they are generally less effective for chronic insomnia.
• Natural Supplements: Melatonin, magnesium, and herbal teas can help improve sleep quality without the side effects of medications.

Alternative Therapies:

Some people find relief through alternative treatments like acupuncture, herbal remedies(e.g., valerian root, chamomile), and aromatherapy with essential oils like lavender.

Prevention Tips for Insomnia:

Preventing insomnia often involves adopting a healthy lifestyle.

• Limited caffeine and alcohol: We should be careful about caffeine and alcohol, especially in the evening. We may leave our alcohol habit, which is not necessary for our body functions.
• Sleep Routine: We can experience many benefits from a good night’s rest by developing a consistent sleeping schedule. We need to listen to our body, which requires rest to gain our energy level and run its function effectively. A consistent sleep schedule will work as the body’s internal clock to improve quality.
• Healthy Eating: We eat to live, but we do not live to eat; remember, to live a healthy life, we should control our food habits. We should maintain a balanced diet that can contribute to better sleep quality and a healthy life.
• Medical Issues: We should address if we feel any unusual symptoms underlying medical or psychological issues that may be contributing to insomnia and seek professional help if necessary.
• Exercise: Regular exercise can help prevent insomnia. We should choose our exercise by considering our age and physical condition or be concerned with a professional to avoid any unexpected situation. Remember, we should not practice intense workouts close to bedtime; it can make it difficult to wind down.
• Establish a Relaxing Bedtime: Make a relaxing bedtime by creating a restful environment with comfortable bedding and a cool temperature. We can take a warm bath or read a book before bed to signal our bodies that it’s time to wind down.
• Deep Breathing: Taking deep breaths before bedtime can help us sleep better through the night.
• Bedtime Prayer: We can pray by giving thanks to God and praying for a peaceful night to wake up happy.

Real-Life Case Studies and Success Stories on Overcoming Insomnia:

Story of Dr. Glidewell:

He is a psychologist, researcher, and founder of The Insomnia Clinic. Once a lifelong insomniac, he dedicates his career to helping others overcome sleep struggles through evidence-based methods.

For the first 30 years of his life, Dr. Glidewell battled relentless insomnia. From restless childhood nights to adulthood marked by sleeplessness, insomnia drained his energy and enthusiasm. Despite consulting doctors and trying various treatments, including medications, nothing seemed to provide lasting relief.

In 2003, during his doctoral training, Dr. Glidewell discovered Cognitive-Behavioral Therapy for Insomnia (CBT-I). He applied these strategies rigorously:

• Changing Sleep Schedules: Establishing a consistent sleep schedule.
• Understanding Circadian Rhythms: Understanding and optimizing his circadian rhythms.
• Adopting New Responses: Changing reactions to sleeplessness to reduce anxiety and promote natural sleep.

These changes transformed his sleep and life, giving him newfound confidence and control.

Dr. Glidewell emphasizes that overcoming insomnia requires a personalized approach, not a one-size-fits-all solution. From his experience, Dr. Glidewell recommends:

• We need to learn about our unique sleep patterns and challenges.
• We should practice CBT-I techniques, such as managing thoughts about sleep and creating a consistent sleep routine.
• Seeking expert guidance when necessary, as navigating sleep transformation alone can feel overwhelming.

He encourages anyone struggling with insomnia to take actionable steps toward better sleep, as vibrant living begins with restorative rest.

Story of Saniya Warwaruk:

Saniya Warwaruk, a millennial with a passion for nutrition, was living her dream after leaving a corporate job to pursue a dietetics degree. But that dream quickly turned into a nightmare as she battled relentless chronic insomnia. Her journey from sleepless nights to rediscovering restful sleep offers hope for others facing similar struggles.

In May 2021, Saniya began experiencing wakefulness at 3 a.m., which soon escalated to sleeping only 1–2 hours per night. Desperate to solve her sleep crisis, she sought medical tests, supplements, and therapies—all of which failed. Her lack of sleep badly affected her mind and body. She felt anxious and sad and even thought about ending her life. Feeling hopeless, she returned to live with her parents, feeling embarrassed and defeated.

The breakthrough came during a camping trip in Banff National Park. Free from the pressure to sleep, Saniya focused on enjoying nature and laughter. Surprisingly, she slept deeply both nights.

Inspired by the work of sleep coach Daniel Erichsen, Saniya embraced a new approach:

1. Exposure Therapy: Treating insomnia as a phobia, she stopped fearing wakefulness and started using sleepless nights for enjoyable activities like reading or watching TV.
2. Letting Go of Control: Instead of following rigid sleep routines or techniques, she embraced relaxation and spontaneity.
3. Shifting Focus: She starts focusing on releasing pressure that leads her to insomnia for her fixing sleep behaviors.
4. She redirected her attention away from “fixing” sleep, removing the pressure that fueled her insomnia.

Saniya advises others struggling with chronic insomnia to:

• Stop chasing sleep or fearing wakefulness; this only amplifies the problem.
• Don’t panic when you are troubled with sleep; try to do something to make you relax or happy.
• Healing takes time, and it sometimes goes in a different line. Be patient and stay strong.
• Remember, the solution lies in breaking the cycle of fear and control.
• Seek help from a professional for better results.

Saniya slowly got her sleep back and started living happily again. From the story, we can learn that we can beat insomnia by staying positive and being patient to overcome it.
