Causes of Insomnia

The symptoms of insomnia vary from one person to another. Likewise, medical health practitioners said that a variety of insomnia symptoms can be experienced by an individual. These symptoms are also related with other medical and or mental illnesses. Most of the time, people with insomnia complain about difficulty falling asleep, which commonly cause the person to toss around the bed for hours. In some cases, one may go to sleep without any problem at all, but he or she would wake up in the early hours of the morning and would not be able to get back to sleep, or he or she may fall into an unsatisfying sleep.

As the course of the disorder often takes place in the bed, a person may begin to associate his or her condition with the said object, making the problem much worse (Mayo Clinic Staff, 2009). It is also worthy to note that difficulty in sleeping is just one of the symptoms of insomnia. The condition may also appear during daytime which, according to doctors, should alert an individual to seek medical aid. Daytime symptoms include lack of concentration and focus, poor memory, impaired coordination of motor skills, irritability, and impaired interpersonal interaction (Health-cares. net, 2005).

Because sleep is an imperative aspect in a person’s life, insomnia can affect an individual mentally and physically. Some of the complications caused by insomnia include low performance at school and job, high-risks of being involved in motor vehicle accidents due to slowed reaction associated with sleep-deprivation, psychiatric problems like anxiety and depression, obesity, increased risks of acquiring long-term diseases diabetes, heart diseases, and high-blood pressure. All in all, compared with people who are sleeping well, individuals suffering from insomnia have a lower quality of life (Mayo Clinic Staff, 2009).

Insomnia is considered as a symptom rather than a stand-alone diagnosis or disorder. As such, this sleeping disorder often stems from another problem. Common causes of insomnia include situational and environmental factors which cause discomfort for an individual’s sleep because they generally interfere the normal sleeping cycle of the person such as jet lag, changing work shifts, excessive noise, uncomfortable room temperature, poor sleeping habits, and eating too much during late in the evening. Insomnia may also be induced by medical causes which can be divided into two categories: psychological and physiological conditions.

Notable psychological conditions associated with insomnia include anxiety, stress, depression, schizophrenia, and bipolar disorder. The physiological causes of insomnia may span from the disturbance of an individual’s biological clock or the circadian rhythm disorder, sleep-wake imbalance, and various other medical illnesses like chronic fatigue syndrome, congestive heart failure, chronic pain syndromes, chronic obstructive pulmonary disease, chest pain from heart disease or night time angina, strokes, brain tumor, and trauma, acid reflux disease, obstructive sleep apnea, and nocturnal asthma.

There are also medications responsible for triggering insomnia. Among them are prescription drugs like antidepressants, medications for heart and blood pressure, allergy medications, corticosteroids and stimulants, and various over-the-counter drugs such as combination of pain medications, weigh-loss products, decongestants, and antihistamines. Other than these, the intake of products, most especially drinks containing caffeine, alcohol, and nicotine which are all stimulants, keeps an individual from falling asleep at night (Mayo Clinic Staff, 2009).
