Insomnia is the inability to fall asleep or remain asleep. Insomnia may result in waking up not feeling restored or refreshed. Insomnia can be either acute, lasting one to several nights, or chronic, lasting months to years. If you have difficulty sleeping, it is essential to determine whether an underlying disease or condition is causing the problem. Sometimes insomnia is caused by pain, digestive problems or a sleep disorder. Insomnia may also signal depression or anxiety. If your sleep trouble is confined to difficulty falling asleep, the time you are choosing to go to sleep may not be synchronized with your biological clock. The prevalence of insomnia is higher among older people and women. Some medications can lead to insomnia, including those taken for:
– colds and allergies
– high blood pressure
– heart disease
– thyroid disease
– birth control
– asthma
– pain medications
– depression (especially SSRI antidepressants)
Some common sleep disorders such as restless legs syndrome and sleep apnea can also lead to insomnia. Sleep is as essential as diet and exercise. Inadequate sleep can result in fatigue, depression, concentration problems, illness and injury.
