Most adults need 7-8 hours of sleep per night. Fewer than 1% of people have a genetic mutation that enables them to be fully rested with 20-25% less sleep. Yet more than one third of all Americans have insomnia which prevents them from getting the sleep they need and 15% of adults suffer from chronic insomnia.
Anxiety can cause or worsen insomnia. Most adults have had some trouble sleeping because they felt worried or nervous. For those with anxiety, the quiet and inactivity of night often brings on stressful thoughts or even fears that can keep a person awake. When this happens for many nights an individual may start to associate feeling anxious with bedtime. In this way, even mild anxiety can lead to chronic insomnia.
Chronic insomnia can also be the result of factors such as: medical conditions (diabetes, neurological disorders); substance use (caffeine, alcohol, prescription medications or tobacco); stress; aging; poor sleep habits; or other mental health issues.
Treatments for insomnia can include behavioral therapy or medications. Medications work faster than behavioral interventions, but they do have side effects. Also, though they may increase sleep time, the drugs used to counteract insomnia usually have a negative impact on the quality of the sleep. Finally, sleep medications can lose effectiveness over time and can be addictive.
The Cognitive Behavioral Therapy (CBT) for insomnia usually takes five to ten weeks. CBT focuses on the behaviors and beliefs that are interfering with sleep. A study by Dr. Ryan Wetzler at Sleep Medicine Specialists in Kentucky found that two to ten sessions of CBT resulted in remission of insomnia in 50-66% of patients. Among those who were using sleep medications three or more days a week, 78% slept better and discontinued using the drugs after just four sessions of CBT.
The Cognitive component of CBT for insomnia involves identifying, challenging and replacing beliefs that create anxiety and beliefs that only perpetuate insomnia. Some unhealthy beliefs about sleep include, “I’m never going to get to sleep” or “I’m going to feel awful tomorrow.”
The Behavioral component of CBT for insomnia is referred to as “sleep hygiene” and is focused on education about optimal sleep conditions and encouraging those struggling with insomnia to incorporate those behaviors into their own sleep regimen. This may involve changing long established patterns – not an easy task.
The sleep hygiene psycho-education about ideal sleep practices includes teaching people to wind-down and practice the same bedtime rituals as a way to signal their body that they are expecting to sleep. It also involves stressing the importance of a regular sleep and wakefulness schedule, and reserving time spent in bed to sleep rather than eating, watching television, worrying or even reading. Sleep hygiene also includes optimizing the bedroom setting by making sure that it is dark, cool and quiet and that the clock is out of view.
Success with a course of CBT for insomnia requires both motivation and commitment. There is “homework” that usually includes keeping a sleep log and expectations about practicing the CBT techniques daily, but the benefits are long-lasting.

es troubling. An evaluation by a trained professional will assess your experience of anxiety and plan the optimal treatment approach for you. A combination of cognitive and behavioral therapies will probably be recommended. Your treatment might also include therapy that involves talking about your past as it relates to your anxiety and addressing any health conditions or personal circumstances that may be impacting your symptoms.
