Sleep is a psychobiological phenomenon i.e. it involves<\/p>\n\n\n\n
Sleep problems can include difficulty getting to sleep, staying asleep or not gaining quality sleep in each stage of the cycle<\/strong><\/p>\n\n\n\n How we sleep can also become a habit but this can be relearned.<\/strong><\/p>\n\n\n\n Insomnia<\/strong> is difficulty sleeping. It is the most commonly reported mental health problem in UK. 40% of those in UK sleep less than 6 hours per night.<\/p>\n\n\n\n Acute < 1 month<\/p>\n\n\n\n Chronic is > 1 month and is related to activation of mind and body<\/p>\n\n\n\n Once we become concerned about sleep we become tense and produce adrenaline, have higher blood pressure and find it difficult to relax. Our body is in the fight flight state and we can start to feel frustrated and angry which makes it worse. Our worry that we won\u2019t sleep then becomes a self-fulfilling prophecy.<\/p>\n\n\n\n The results of poor quality sleep<\/strong><\/p>\n\n\n\n Low concentration High irritability<\/p>\n\n\n\n Low memory function High frustration<\/p>\n\n\n\n Low immune system High sleepiness<\/p>\n\n\n\n Note: fatigue is different to feeling sleepy. Fatigue is a lack of energy while wide awake and doesn\u2019t make you want to sleep.<\/p>\n\n\n\n Sleep and Pain<\/strong><\/p>\n\n\n\n Pain is also a psychobiological process<\/strong>. If we stub our toe we have acute pain.<\/strong> The message travels up our spinal cord through what we call the pain gate and is interpreted by our brain. The pain is felt in the brain not the toe. In a few minutes the pain will pass and we forget about it. We call this an acute pain. This does not tend to interrupt sleep.<\/p>\n\n\n\n When a pain goes on for a long time it takes on a different meaning<\/strong> to us. We begin to expect it, to look for it and dread it which in turn can cause low mood. We can feel helpless to stop what is hurting us. This is chronic pain<\/strong> and is made up of 2 elements<\/p>\n\n\n\n Sometimes the primary pain can go away but the secondary pain remains long afterwards because of our perception of it. <\/p>\n\n\n\n Experience of pain which becomes chronic reduces the quality of our sleep because <\/p>\n\n\n\n The good news is that once we start to think about making our quality of sleep better the research suggests we can usually find at least some way of improving things.<\/strong><\/p>\n\n\n\n Quality and duration of sleep tend to increase.<\/p>\n\n\n\n What do we need to know?<\/strong><\/p>\n\n\n\n Effects of Light<\/p>\n\n\n\n The master clock for the brain is made up of a group nerve cells found just above the optic nerve (SCN – Suprachiasmatic nucleus) and is controlled in the hypothalamus. 3 types of light sensor in the eye (rods, cones (colour), and a brightness detector). Signals pass from the eye to the brain about the amount of light in the environment. As the amount of light decreases the brain gets the signal to create more melatonin which makes us feel sleepy.<\/p>\n\n\n\n Humans naturally sleep nights and wake during the daytime. There is a genetic element to whether you are a morning person or more prone to insomnia but within this you can still make adjustments. People regularly working shifts for example affect their natural pattern which causes increases in ill health.<\/p>\n\n\n\n Psychological Health<\/strong><\/p>\n\n\n\n Experience of psychological health issues can affect the sleep cycle. <\/strong>Poor sleep makes us less receptive to positive emotions and we are therefore more likely to feel miserable during the day.<\/p>\n\n\n\n Depression<\/strong> – REM sleep and the number of eye movements within that sleep is greater. The sleeper enters REM sleep earlier in the cycle. It is thought that increased dreaming may cause a vulnerability to increased Depression.<\/p>\n\n\n\n Both dreams and hallucinations involve deregulation of dopamine production. The level of dopamine affects pain perception, movement, memory, problem solving, attention and planning.<\/p>\n\n\n\n Anxiety <\/strong>\u2013 when anxious a sleeper spends less time in deep sleep. This is a refreshing part of sleep which consolidates the learning and memories of that day (Non REM). <\/p>\n\n\n\n The anxious mind finds it difficult to relax which causes increased arousal and adrenaline<\/p>\n\n\n\n We worry that we won\u2019t sleep which becomes a self-fulfilling prophecy e.g. we clock watch and think about how much sleep we have missed<\/p>\n\n\n\n The clock takes on a new meaning and becomes a measure of our success or failure at sleeping. Its presence on the bedside table can become a constant critic of our sleep performance.<\/p>\n\n\n\n Great British Sleep Survey (2016) spoke to (N= 6708, 1\/3 Men, 2\/3 Women) people about their sleep experiences.<\/strong><\/p>\n\n\n\n They reported insomnia affected; mood, energy, relationships, irritability, ability to stay awake during the day, ability to carry out tasks effectively.<\/p>\n\n\n\n Over sleeping began to occur among 15-40% of those who reported feeling depressed.<\/p>\n\n\n\n Hormonal changes resulting in increased likelihood of type 2 diabetes & obesity.<\/p>\n\n\n\n Decreased capacity to exercise which had a negative effect on mental wellbeing and therefore further contributed to insomnia.<\/p>\n\n\n\n Sleep Behaviours Can Become a Habit<\/strong><\/p>\n\n\n\n e.g. Sleep Grazing<\/strong><\/p>\n\n\n\n When we are tired it is tempting to sleep graze by taking little naps during the day.<\/p>\n\n\n\n The problem with this is that it:<\/p>\n\n\n\n Physical Health<\/strong><\/p>\n\n\n\n Physical health can restrict sleep from something as basic as a cold which stops you breathing due to a blocked nose.<\/p>\n\n\n\n e.g. Sleep Apnoea \u2013 snoring during REM sleep due to pauses in breathing. Caused by tissue at back of throat and base of tongue which obstructs airways. It is affected by the shape of the neck, alcohol, smoking and weight. More common in older men. Can be treated with positive airway pressure mask.<\/p>\n\n\n\n What Can We Do to help address this?<\/strong><\/p>\n\n\n\n How to Improve Our Sleep Stimulates the Central Nervous System<\/p>\n\n\n\n Causes increased heart rate<\/p>\n\n\n\n Causes adrenaline production<\/p>\n\n\n\n Suppresses melatonin a hormone which helps us feel sleepy<\/p>\n\n\n\n Alcohol Interrupts sleep pattern in the second half of the night<\/p>\n\n\n\n Diuretic so need to get up to the toilet<\/p>\n\n\n\n Is a depressant and causes low mood which reduces sleep<\/p>\n\n\n\n Going cold turkey after a lot of alcohol causes withdrawal symptoms<\/p>\n\n\n\n Food Rice\/oats cause small melatonin production<\/p>\n\n\n\n Diary contain tryptophan which aid manufacture of melatonin in body<\/p>\n\n\n\n Refined Sugar Exercise Older adults found to sleep better with aerobic exercise<\/p>\n\n\n\n Physical fitness increases metabolism which results in better sleep<\/p>\n\n\n\n Reduces anxiety and improves mood causing better sleep<\/p>\n\n\n\n Light management No alarm with permanent light on bedside<\/p>\n\n\n\n Reduce blue light exposure<\/p>\n\n\n\n Stop interaction on social media etc at least an hour before sleep<\/p>\n\n\n\n Low lighting on run down to sleep<\/p>\n\n\n\n Blackout when wish to sleep (Blackout curtains in summer) Noise stopped \u2013 or earplugs can help<\/p>\n\n\n\n Temperature \u2013 not too hot (17 degrees)<\/p>\n\n\n\n Good ventilation<\/p>\n\n\n\n Medication Psychological Approaches<\/strong> Cognitive Behavioural Therapy (CBT) has been found to be an effective part in treatment of insomnia. Including this as treatment package as follows will maximise your chances of making a positive change;<\/p>\n\n\n\n Relaxation Useful to use<\/p>\n\n\n\n These all take practice before they are mastered and it may take a little while to start to feel it is a comfortable part of your routine.<\/p>\n\n\n\n Adjusting Sleep Patterns Review findings in light of sleep hygiene protocol<\/p>\n\n\n\n Altering the Thought and Behaviour Which Hinder Sleep<\/strong><\/p>\n\n\n\n Make the bedroom the place to sleep not eat\/work\/watch TV. If you wake and don\u2019t get back to sleep within a few minutes try a relaxation exercise. If still awake get up and do something relaxing like reading the paper in another room until feel sleepy then return to bed.<\/p>\n\n\n\n If you have a chronic pattern can use sleep restriction but with professional help.<\/p>\n\n\n\n Use of Thoughts monitoring (See Thoughts Diary)<\/p>\n\n\n\n Useful References<\/p>\n\n\n\n Sleep is a psychobiological phenomenon i.e. it involves (1) How we feel physically (2) How we feel emotionally (3) Our thoughts (4) Our behaviour Sleep problems can include difficulty getting to sleep, staying asleep or not gaining quality sleep in each stage of the cycle How we sleep can also become a habit but this … <\/p>\n
Good sleep hygiene can improve our sleep quality
Caffeine
<\/strong>Stays in the system a long time as it is hard for the body to break down<\/p>\n\n\n\n
<\/strong>Makes us fall asleep more easily but the quality of sleep is not as good<\/p>\n\n\n\n
<\/strong>Difficult to sleep if hungry so light snack can help (not protein)<\/p>\n\n\n\n
<\/strong>Makes us more active and less sleepy<\/p>\n\n\n\n
<\/strong>Better earlier in the day as increases adrenaline<\/p>\n\n\n\n
<\/strong>No IT equipment or TV in bedroom<\/p>\n\n\n\n
Environment<\/strong>
Comfortable bed<\/p>\n\n\n\n
<\/strong>Most common sleep medications are called hypnotics. Only helpful in short term (NICE guidelines say 2-4 weeks) as they are addictive also have rebound effects once come off them which can make sleep worse than it was to start with.<\/p>\n\n\n\n
Aim to challenge the underlying thoughts and feelings about sleep.<\/p>\n\n\n\n
<\/strong>People with insomnia often find it difficult to relax naturally before they go to sleep<\/p>\n\n\n\n
<\/strong>Monitor sleep diary for 2 weeks to see what is actually happening<\/p>\n\n\n\n
