Sleep Therapy: Understanding The Process And Benefits

what happens in sleep therapy

Sleep therapy is a form of therapy designed to improve the quality of sleep. It can help with sleep disorders like insomnia, restless leg syndrome, sleep apnea, and narcolepsy, as well as other mental and physical health conditions. Sleep therapy can involve cognitive-behavioural therapy (CBT), which focuses on changing negative thoughts and behaviours that contribute to sleep problems. CBT can be tailored to individual needs and can be conducted in person or online. Other forms of sleep therapy include the use of medication, supplements, and electro-sleep therapy, which involves placing electrodes on the patient's head and eyelids to induce relaxation.

Cognitive behavioural therapy (CBT)

CBT-I focuses on restructuring the thoughts, feelings, and behaviours that contribute to insomnia. It involves cognitive, behavioural, and educational components. Cognitive interventions attempt to change inaccurate or unhelpful thoughts about sleep. This involves examining and testing thoughts and feelings about sleep to see if they are accurate, and then clarifying or reframing misconceptions in a way that promotes restful sleep. Behavioural interventions include stimulus control, sleep restriction, and relaxation techniques to establish healthy pre-sleep habits. Psychoeducational interventions provide information about the connection between thoughts, feelings, behaviours, and sleep.

Therapists work with patients to identify the most relevant targets for behaviour changes and help them overcome obstacles to making necessary changes. This may include re-evaluating beliefs about sleep that are causing unnecessary anxiety. CBT-I guides patients through changes in sleep-related behaviours, helping them identify and eliminate habits that are ineffective and reduce sleep-related worry.

CBT-I is often provided by a doctor, counsellor, therapist, or psychiatrist trained in this form of treatment. However, due to the widespread need for this treatment, there is a limited number of qualified CBT-I professionals. As a result, new ways of offering CBT-I have been developed, including digital applications, group therapy, and self-help formats.

Sleep hygiene

Creating a comfortable and calm bedroom environment is also important for sleep hygiene. This includes minimising disruptions such as noise and light, setting a comfortable temperature, and using comfortable bedding and mattresses. It is also recommended to restrict in-bed activities to sleep and sex, as this helps build a link between sleep and being in bed.

Additionally, sleep hygiene involves adopting healthy habits and behaviours throughout the day. This includes limiting caffeine, alcohol, and nicotine consumption, especially close to bedtime, as these substances can interfere with sleep. Engaging in regular exercise during the day can also help improve sleep quality, although exercising too late in the day may delay falling asleep. It is also beneficial to wind down before bed by avoiding stressful activities and electronic devices, and instead engaging in relaxing activities such as reading or listening to calming music.

While sleep hygiene can be an effective component of therapy for insomnia, it may not be sufficient as a standalone treatment. Combining sleep hygiene education with other therapies, such as cognitive behavioural therapy, can lead to improved sleep for individuals with insomnia.

Relaxation techniques

Sleep therapy is a broad term for the treatment of sleep disorders, which affect the quality and duration of sleep and wakefulness. There are over 80 types of sleep disorders, including insomnia, sleep apnea, and restless leg syndrome. Treatment options for sleep disorders include medication, light therapy, and cognitive behavioural therapy (CBT-I).

CBT-I is a short, structured, and evidence-based approach to treating insomnia. It involves restructuring thoughts, feelings, and behaviours that contribute to insomnia through psychoeducation, cognitive restructuring, and behavioural interventions. Behavioural interventions include stimulus control, sleep restriction, and relaxation training.

Relaxation training is a crucial component of CBT-I, helping to establish healthy pre-sleep habits. Here are some relaxation techniques that can help you fall asleep:

Progressive Muscle Relaxation

This technique involves gradually tensing and relaxing muscles, starting with the toes and working up the body. Focus on your toes and feet. Curl your toes and arch your feet, then relax your muscles and let your feet sink. Move your attention slowly up your body, tensing then relaxing each area, including your calves, thighs, buttocks, and so on. If distracting thoughts come to mind, gently shift your attention back to your breathing.

Diaphragmatic Breathing

Also known as belly breathing, this technique involves taking slow, deep breaths to engage the large muscle at the base of the lungs. Diaphragmatic breathing can reduce stress, increase relaxation, strengthen the diaphragm, and improve breathing efficiency.

Yoga Nidra

Yoga nidra is a technique that relies on mental imagery while lying on your back. Lie flat with your hands apart and think of a short, positive phrase or mantra. Increase your body awareness by visualising different parts of your body in succession. Focus on each breath, imagining the air flowing in and out of your body. Recall personal experiences, feelings, and sensations, both positive and negative. Visualise each scene and emotion as if it were happening in the present moment. Repeat the positive phrase and return your awareness to the present.

Meditation

Find a quiet place to sit or lie down in a comfortable position. Close your eyes and breathe slowly in and out for about five minutes. As you inhale, breathe down into your belly. Focus on your breath and, if you like, repeat a calming phrase such as "Breathing in I am calm, breathing out I am coping."

Non-Sleep Deep Relaxation (NSDR)

Get comfortable and lie down with your eyes closed. Focus on your body and imagine your muscles relaxing. Inhale through your nose and exhale slowly through your mouth. Imagine sinking deeper into the surface as you relax. Stay focused on resting and avoid letting your mind wander.

Remember, these exercises are generally safe, but it's always a good idea to consult your doctor before trying new techniques, especially if you have epilepsy, psychiatric conditions, or a history of trauma.

Sleep medication

Sleeping pills are the most common form of sleep medication. They make the user feel drowsy and relaxed, helping them to fall asleep and stay asleep. Pills can be prescribed by a doctor, or bought over the counter as natural sleep aids, such as melatonin. However, medication can have side effects, including daytime sleepiness and confusion. In some cases, users may even eat or walk in their sleep (parasomnia).

Due to the potential side effects and limited benefits, it is recommended that other methods are tried before sleep medication. These include changing your sleeping routine and environment, and trying cognitive behavioural therapy (CBT). CBT-I (Cognitive Behavioural Therapy for Insomnia) is an evidence-based approach that has been shown to be effective for both short-term and chronic insomnia. It involves restructuring thoughts, feelings, and behaviours that contribute to insomnia, and techniques include stimulus control, sleep restriction, and relaxation training.

If insomnia persists, a doctor may prescribe medication to be used alongside CBT-I. This could include sleeping pills, or other drugs such as anti-Parkinsonian drugs, benzodiazepines, antinarcoleptics, or antidepressants/antianxiety medications.

Electro-sleep therapy

The concept of electrosleep was first investigated at the beginning of the 20th century, with most early research and applications occurring in Russia. In the 1960s, it gained popularity in the United States, although the name was changed from "electrosleep" to "cranial electrical stimulation" as it was believed that the treatment did not induce sleep but rather that sleep was a side effect of the relaxing effect of the current stimulation.

CES is a non-invasive method of applying low-intensity electrical currents to the head, and it is related to other forms of transcranial electrical stimulation such as electroconvulsive therapy and transcranial direct current stimulation (tDCS). The placement of electrodes, the intensity of the current, and the waveform of the current can vary depending on the specific version of transcranial electrical stimulation being used.

There have been several studies examining the effectiveness of electrosleep therapy in treating insomnia and other conditions. One study involving 30 chronic insomnia patients found that after a 6-week electrostatic therapy program, there was a significant improvement in insomnia severity as measured by the Insomnia Severity Index (ISI). Additionally, there was a reduction in daytime sleepiness and fatigue, as assessed by the Epworth Sleepiness Scale (ESS) and Flinders Fatigue Scale (FFS), respectively. However, another study involving 57 participants showed no significant changes in total sleep time (TST) following a 5-day CES treatment.

It is important to note that the use of CES devices may require a prescription and be restricted to use by licensed healthcare practitioners, depending on the regulations of a particular country or region. For example, in the United States, the Food and Drug Administration (FDA) classifies CES technology as a Class III medical device.

Frequently asked questions

Sleep therapy is a form of therapy designed to improve sleep quality. It can help with sleep disorders like insomnia, restless leg syndrome, sleep apnea, and narcolepsy, as well as mental and physical health conditions.

Sleep therapy can take various forms, including cognitive-behavioural therapy (CBT), electro-sleep therapy, and pharmacologically induced sleep. CBT is the most widely used therapy for sleep disorders. It involves changing behaviours and thoughts that interfere with sleep, improving relaxation skills, and altering lifestyle habits that impact sleep. Electro-sleep therapy involves placing electrodes on the patient's head and eyelids to induce relaxation and sleepiness. Pharmacologically induced sleep therapy involves drug combinations to induce sleep for extended periods.

CBT-I helps individuals recognise and replace unhealthy sleep-related thoughts and behaviours with healthier habits and attitudes. It utilises a technique called paradoxical intention, where patients commit to staying awake while lying in bed, which can reduce anxiety about falling asleep. CBT-I also includes stimulus control, sleep restriction, and relaxation training.

CBT-I has been shown to be effective in improving sleep quality, with benefits lasting up to a year after treatment. A Harvard Medical School study found CBT to be more effective than prescription sleep medication in treating chronic insomnia. Sleep therapy can also help address the underlying causes of sleep disorders, such as mental health issues, rather than just treating symptoms.

Sleep therapists specialising in CBT-I can be located through professional organisations such as the American Psychological Association, American Board of Sleep Medicine, and the Society of Behavioral Sleep Medicine.
