What Are The Causes of Insomnia?

What Are The Causes of Insomnia in Humans? The cause of a person suffering from insomnia can vary, including: psychological problems, physical health problems, side effects of medication, lifestyle, and comfort factors in the room.

Psychological problems

Psychological problems are often a major factor in the emergence of symptoms of insomnia, one of which is stress. Many people who sleep become annoyed because of stress. Examples of stressors can vary. There is stress from school, work, financial problems, and stress from family and social relationships. In addition to stress, depression due to loss of the nearest person, loss of work, or loss of other valuable things can also cause insomnia.

Insomnia can also be caused by anxiety. People with anxiety will find it difficult to start sleeping. In addition, anxiety can also make a person difficult to maintain sleep, so he often woke up in the middle of the night and difficult to sleep again. Examples of anxiety can vary, including anxiety about financial condition, future, and anxiety in taking responsibility. Even anxiety and panic for not sleeping can make a person really can not sleep.

In addition to stress or anxiety, other psychological problems that can cause insomnia are mental illnesses, such as schizophrenia and bipolar disorder.

Underlying physical health problems

Many physical health problems can cause symptoms that can make a person feel uncomfortable and thus have difficulty getting started or maintaining sleep, for example:

  • Suffering from a disease that causes prolonged pain
  • Respiratory disorders (asthma and lung disease)
  • Cardiac disorders (heart failure and angina)
  • Muscle and joint problems (arthritis)
  • Hormonal disorders (hyperthyroidism)
  • Nerve disorders (Parkinson’s disease and Alzheimer’s disease)
  • Problems with the urinary organs (enlarged prostate and urinary incontinence)
  • Cancer
  • Digestive disorders (GERD disease)
  • Stroke
  • Other sleep disorders (sleep disorders walking, snoring, narcolepsy, restless legs syndrome, or sleep apnea)

Bad lifestyle

Insomnia can be triggered by certain habits or lifestyle that we live, one of which is the time of sleep is not fixed. Our ever-changing sleep time can cause circadian rhythms that regulate the body’s metabolism, including sleep and wake cycles, to be disturbed.

Examples of such insomnia are often experienced by people who work at irregular times, those who have the habit of taking a nap to replace the lack of nighttime sleep, and those who experience desynchronosis or experience after a long-haul flight.

Eating large portions of food can also make a person difficult to sleep. Abdomen that is too full can make the body uncomfortable when rested. Sleeping shortly after eating can also potentially cause heartburn. Of course with these conditions, sleep will be disrupted.

Just like large portions of food, excessive consumption of caffeinated beverages, nicotine and alcoholic beverages should be avoided just before bedtime. Alcohol does contain a sedative that can help speed up your sleep, but can not make you sleep until it reaches a more sound stage.

Environmental factor

Uncomfortable bedroom environment can disrupt one’s sleep, such as room temperature is too cold or hot, noise, and light is too bright.


Some types of drugs (whether sold freely in pharmacies or must be prescribed by a doctor) have side effects that can cause insomnia for people who consume them. Examples of such drugs are:

  • Nonsteroidal anti-inflammatory drugs / NSAIDs
  • Salmeterol, salbutamol, and theophulline (asthma drugs) Beta blocking drugs (usually used for high blood pressure)
  • Some types of antidepressants
  • Allergy medicines
  • Steroid drugs
  • The stimulant drugs used to treat narcolepsy and hyperactivity disorder
  • Epilepsy drugs
