Reasons for Insomnia and why it is harmful?

Insomnia Sleep Disorder

Almost everyone experiences insomnia from time to time. Insomnia is a common sleep disorder involving difficulty falling or staying asleep. It can be a short-term problem or a chronic disorder that can last for months or even years.

Signs and symptoms of Insomnia

  • Difficulty falling asleep
  • Waking up several times during the night
  • Waking up early in the morning and not being able to get back to sleep
  • Not feeling refreshed when you wake up
  • Difficulty napping during the day despite feeling tired
  • Feeling tired and irritable during the day
  • Difficulty concentrating
  • Affecting one’s quality of life, mood, and relationships with friends, family, and colleagues.

When someone has persistent insomnia, it can have a dramatic effect on their life. Chronic insomnia usually has a cause, such as,

  • Stress and anxiety
  • Improper sleep habits
  • Not sleeping on a regular schedule due to work or travel
  • Mental health disorders
  • Medications such as antidepressants or pain medications
  • Conditions such as cancer, heart disease, asthma or hormonal imbalance
  • Chronic pain such as arthritis
  • Poor sleeping environments such as dirty beddings, too much noise or cold, etc.

According to Human growth hormone deficiency can lead to bad sleep or chronic insomnia. Human growth hormone (HGH) is produced by the pituitary gland that helps the body grow and develop.

When the body does not produce enough HGH, it leads to several problems, including difficulty sleeping or chronic insomnia. This is because HGH helps regulate the body’s circadian rhythm, which controls the sleep/wake cycle. Also, HGH deficiency can cause feelings of fatigue, which can further disrupt sleep.

There are serious health risks associated with chronic insomnia, such as,

  • Stroke. A stroke occurs when the brain does not get enough oxygen, which can happen if someone has chronic insomnia. This lack of oxygen can cause the brain cells to die, leading to permanent disability or even death.
  • Seizures. Chronic insomnia can disrupt the brain’s electrical activity, leading to seizures.
  • Weak immune system. Chronic insomnia weakens the body’s immune system, making it harder for the body to fight off infections and diseases.
  • Obesity. People with chronic insomnia are more likely to be overweight or obese because they tend to eat more calories than they burn off due to lack of sleep.
  • Heart diseases. With the condition causing an inability to regulate hormones properly, the victim becomes exposed to heart diseases.
  • Sex drive. People with chronic insomnia are more likely to suffer from decreased libido due to the lack of energy and decreased mental health associated with the condition.
  • Memory. The memory may get distracted when the victim lacks enough sleep. It becomes hard to concentrate and remember things.
  • Depression
  • Anxiety
  • Diabetes
  • High blood pressure

How much sleep do you need?

Most adults generally need between seven and nine hours of sleep per night to be at their best. Sleep quality is just as important as quantity; it’s not enough to sleep for the recommended amount of time. Restful sleep is necessary for the body to repair and rejuvenate itself.

If you’re having trouble falling or staying asleep or waking up feeling unrested, it may be a sign that you need to make some changes in your sleep routine.

How Insomnia is diagnosed

In order to diagnose insomnia, a healthcare provider will assess the patient’s overall health and sleep history. This usually involves a physical exam and questions about the patient’s sleep habits. Blood tests may also rule out any underlying medical conditions contributing to insomnia.

Additionally, the patient may be asked to keep a sleep diary for one to two weeks to identify any patterns or behaviors that interfere with rest. In some cases, a sleep study (polysomnogram) may be recommended if the healthcare provider suspects another sleep disorder, such as sleep apnea, may be causing insomnia.

This sleep study involves monitoring the patient’s brain waves, breathing, and other body movements during sleep. The results can help diagnose the underlying cause of insomnia and provide the doctor with more information to create a customized treatment plan.

How to manage Insomnia

  • Practice good sleep hygiene

Make sure to create a good sleep environment by keeping the bedroom dark, quiet and comfortable. Establish a sleep schedule and stick to it by going to bed and waking up at the same time every day, even on weekends. Avoid stimulants like caffeine late in the day, and minimize screen time before bed.

  • Exercise regularly

Regular physical activity can help you to fall asleep faster and sleep more deeply. Try to complete any vigorous activity at least three hours before bed.

  • Manage stress

Stress can interfere with sleep, so finding ways to manage stress can help you sleep better. Techniques such as deep breathing, progressive muscle relaxation, and mindfulness meditation can help to reduce tension and anxiety.

  • Avoid naps

Napping during the day can make it more difficult to sleep at night, so limiting your naps to 15-20 minutes in the early afternoon can help.

  • Medication

For short-term relief, a doctor may prescribe medication to help with sleep. However, this should only be used as a short-term solution since it is not recommended for long-term use.


Understanding the signs and symptoms of insomnia and its causes is important to create an effective treatment plan. There are many ways to manage insomnia, such as practicing good sleep hygiene and managing stress, as well as medication if needed. If you are having difficulty sleeping, talk to your healthcare provider about the best treatment options.
