Causes And Risk Factors Of Insomnia
Insomnia can be caused by:
•Stress-related factors significant personal events, such as losing a job, marital problems, stress and worry.
•Psychiatric conditions, such as depression, anxiety and schizophrenia.
•Medical illness. Certain medical illness can interfere with sleep, especially disorders of the heart (congestive heart failure), lungs (chronic obstructive pulmonary disease), kidneys, liver, pancreas and digestive system (peptic ulcer). Other important physical causes include heartburn, prostatism, menopause, diabetes, arthritis, hyperthyroidism and hypoglycemia.
•Obstructive sleep apnea syndrome, where the obstruction of the airway caused by the sagging muscles at the base of the throat. The muscles obstruct the airway causing labored breathing and loud snoring. If complete blockage occurs, breathing stops and the sleeper falls silent. Opening of the blockage is signaled by a gasp and the sleeper awakening throughout the night during these episodes.
•Periodic limb movement disorder, the recurring movements of the legs.
•Restless leg syndrome, an unpleasant tickling, burning, pricking or aching sensations in the muscles of the legs.
•Psychophysiologic ("Learned") insomnia, the severe difficulty in initiating and maintaining sleep. Many people go to bed worrying about insomnia because of previous episodes, and this thinking produces an adverse association between the bedroom and sleep.
•Circadian Rhythm Sleep Disorder (Sleep-wake Disorder), which occurs when your internal clock gets out of sync with your sleep schedule.
•Biological factors. As you age, sleep becomes lighter and more fragmented. While young people tent to have problems falling asleep, older people struggle with staying asleep. During our life spans, the internal biological "clock" that regulates sleep creeps slightly forward, compelling most older people to go to sleep earlier and to wake earlier.
•Lifestyle factors. Excessive caffeine consumption, alcohol and drug abuse, poor sleeping habits, shift work change and misuse of certain medications such as anticholinergics (used for treatment of asthma), antidepressants, antihypertensives (used for treatment of high blood pressure, stroke and heart failure), antineoplastic agents, corticosteroids, diuretics, histamine blockers and respiratory stimulants.
•Environmental factors. Noise, light and stale air can cause insomnia.
