What Causes Insomnia? Medical vs Lifestyle Factors

Insomnia or sleeplessness is caused by both lifestyle and medical factors, such as anxiety, stress, poor sleep habits, or disruptions to the body’s internal clock. Medical factors, such as acid reflux, chronic pain, certain medications, and hormonal changes, also disrupt an individual’s sleep. Whatever the factors may be, you can treat insomnia with UK sleeping pills and positive sleep habits.

Enjoying a good night’s sleep in the present era has become challenging for a number of reasons. Lifestyle factors, medical conditions, and stress snatch a person’s relaxing sleep in the night, resulting in a lack of focus the next day. Besides, the influx of digital technology has also added to this health issue. Many of us check our phones and use laptops before or in bed, which makes it difficult to fall asleep comfortably.

On average, a healthy, normal adult needs seven to nine hours of good sleep. The timing may vary from individual to individual depending upon their age, lifestyle, environment, health, and diet. Insomnia happens when you cannot sleep for more than three nights, for three months or more. If you are undergoing such a situation, you might have insomnia. This blog explains different causes of insomnia, how to treat it, and what healthy habits can help you enjoy better sleep.

Common Symptoms of Insomnia 

  • Trouble falling asleep is the most common symptom.

  • Waking up during the night happens often.

  • Some people wake up too early and cannot get back to sleep.

  • Feeling tired or low in energy during the day is common.

  • It can be hard to focus or stay alert.

  • Mood swings or feeling down may occur.

  • Many people feel anxious or worried about not sleeping well.

  • Insomnia can last for a short time or become long-term.

  • Short-term insomnia may last a few days or weeks.

  • It is often caused by stress at work or personal problems.

  • Almost everyone experiences short-term sleep issues at some point.

  • It usually improves when the cause or stress fades away.

  • If sleep problems last longer than three months, it is called chronic insomnia.

  • Chronic insomnia needs medical advice and treatment.

  • It is important to talk to a doctor as soon as sleep troubles begin.

  • Getting early help can make it easier to recover and sleep better again.

Medical Causes of Insomnia

Short-term insomnia can be a symptom of, or be triggered by, some physical and mental health problems mentioned below: 

Physical Health Conditions

Chronic Pain: Constant pain from back problems, arthritis, or fibromyalgia can cause trouble falling asleep or lead to frequent awakenings in the night.

Respiratory Issues: Health issues like sleep apnea or asthma may obstruct your quality of sleep due to breathing problems.

Gastrointestinal Issues: Taking meals at night and eating large quantities or having acid reflux (GERD) may disturb you the whole night and keep you from sleeping.

Neurological Conditions: Disorders like restless legs syndrome, Parkinson's disease, and Alzheimer's disease often cause sleep disruptions.

Hormonal Changes: Pregnancy, menopause (hot flashes and night sweats), and an overactive thyroid may hit your sleep patterns hard, keeping you awake.

Other Conditions: Heart diseases, diabetes, bladder instability, and prostate problems can also lead to disrupted sleep. 

Mental Health Conditions

Stress: Mental health disorders, like feeling anxious or worried about family, work, or finances, may keep the mind active and increase the risk of insomnia.

Anxiety and Depression: Both are strongly connected with insomnia, often developing a vicious cycle where sleeplessness aggravates mental health and vice versa.

Trauma/Grief: Certain life events, such as a job loss or a bereavement, can cause insomnia. 

Medications and Substances

Recommended Medicines: Certain antidepressants, epilepsy medicines, blood pressure medications, and steroids can disturb sleep.

Over-the-Counter Medications: Some allergy and cold medicines, pain relievers, and weight-loss products contain ingredients that interfere with your sleep patterns. 

Alcohol and Caffeine: If you drink too much alcohol or take tea or coffee at night, it might disrupt your sleep cycle, ultimately leading to insomnia.

Lifestyle Factors

Daily habits and your surroundings play a key role in your ability to sleep. Here are some lifestyle habits that can cause insomnia:

Lifestyle Habits

Irregular sleep schedule interferes with your body's natural circadian rhythm, ultimately causing insomnia.

Stimulant Use: Consuming alcohol, caffeine, or nicotine just before bedtime serves as a stimulant and disturbs your sleep architecture later in the night.

Napping: Daytime naps, particularly late-afternoon ones, reduce your body's need for sleep at night, increasing the risk of long-term insomnia.

Lack of Activity: A sedentary lifestyle or workouts just before bedtime can disrupt your sleep.

Eating Habits: Eating heavy meals late in the evening can cause discomfort or heartburn.

Excessive Screen Time:  Blue light emitted by your phones, tablets, or computers can interrupt your sleep.

Uncomfortable Environment: A bedroom that is too bright, noisy, hot, or cold can also contribute to insomnia.

  • Avoid using your phone, laptop, tablet, or TV an hour before bed.

  • Watching the clock can make you anxious and stop you from falling back asleep.

When to See a Doctor?

Insomnia can be managed with simple lifestyle changes, helpful medications, and therapies like cognitive behavioural therapy (CBT). If home remedies and sleep habits don’t work and sleep disruptions still exist, you can consult your healthcare provider. Your sleep physician will assess your symptoms, observe health conditions, if any, and recommend effective medicines to treat your insomnia.

It is advisable for people with insomnia to follow the directions given by their doctor to achieve good results. Also, avoid substances that have been the cause of sleep disruptions. And when insomnia is over, consider stopping the medicine slowly after speaking to your doctor. All these things would add up to treat your insomnia in less time than you expected.
