Around a third of adults in the UK have problems with insomnia at some stage.
Getting a good night's sleep long term does not begin with sleep prescribed by your GP.
Good sleep starts with what experts call sleep hygiene, including a good bedtime routine and simple lifestyle changes.
Lifestyle modifications and cognitive behavioural treatments for sleep problems may include:
Sleep hygiene for sleep disorders
Sleep hygiene refers to practices, habits, and environmental factors that are important for getting sound sleep. The four general areas important to sleep hygiene are the circadian rhythm (24-hour cycle), ageing, psychological stressors that cause mini-awakenings (in which the brain wakes up for just a few seconds), and stimulant use.
- Circadian rhythms influence when, how much, and how well people sleep. These rhythms may be altered by the timing of various factors, including naps, bedtime, exercise, and exposure to light.
- Ageing also plays a role in sleep. Sleep patterns change after people reach the age of 40. There are many more nocturnal awakenings as people age. The awakenings affect sleep quality and can interact with any other condition that may cause arousals or awakenings. The more awakenings people experience at night, the more likely they will awaken with a feeling of not being rested.
- Psychological stressors such as exams, deadlines, or job problems may interfere with sleep. It is beneficial for people to develop some kind of pre-sleep ritual to break the connection between stress and bedtime. Some people find it helpful to make a list of all the stressors of the day, along with a plan to deal with them. In addition, periods of relaxation (meditating or taking a warm hot bath) can help a person relax and get to sleep.
- Stimulants can stay in the body as long as 14 hours and can increase the number of times you awaken at night, decreasing your total amount of sleep time. Avoid caffeine, nicotine and alcohol. The effects of nicotine, when consumed in high doses, are similar to those of caffeine. Alcohol may initially sedate you, making it easier to fall asleep. The downside to alcohol is that as it is metabolised and cleared from your system during sleep, it causes arousals that can occur as long as two to three hours after it has been eliminated.
Relaxation training for sleep disorders
Methods such as progressive muscle relaxation (PMR), deep breathing techniques, imagery, and self- hypnosis may help some people overcome a sleep disorder. PMR involves helping the individual to sequentially tense and relax the body’s major muscle groups while concentrating on and contrasting sensations of tension and relaxation. Daily practice of relaxation techniques between therapy sessions is essential and tends to enhance the effectiveness of the treatment.
