Most of us are not getting enough sleep, but it’s more complex than you might think.

Some of the facts around sleep, and its role on our health and wellbeing, are still a mystery, even to scientists.  The Daily Mirror reported that one survey found that “Nearly a third of the population are suffering from insomnia which is affecting their health”.  This survey of the nation’s sleep habits found that 30% of people are severely sleep deprived, placing them more at risk of mental health and relationship issues.

During sleep the body goes through a variety of processes and sleep stages.   Each sleep stage has its own purpose and requires a certain amount of time to bring about optimum results.  Sleep that is thought of as ‘good quality’ is likely to be the result of spending enough time in all of those stages, including enough deep sleep to support us in feeling refreshed and rejuvenated.

What Does the Literature Say?
Sleep and our health and wellbeing are strongly linked.  Sleep plays an important role in the process of our bodies repairing themselves, and in our brain’s consolidation of our memories, indeed it’s during sleep that we organise information into our long term memories.  ‘Restful’ sleep also accommodates brain plasticity, that is the ability to change neuro patterns and behaviours
(Ref 1).  Poor sleep increases the risk of poor health which in turn can make it harder to sleep, and the cycle can lead to both physical issues (such as weakened immune systems), and mental issues (such as anxiety and depression).

The biggest study on sleep and sleep habits in the UK heard from nearly 7,000 citizens, and found that the following were stated to be the most common reasons for poor sleep:

  • Men’s average sleep score was 61%, compared to 57% for women.
  • People who said they were in poor health had poorer sleep (average sleep score of 47%) than those who rated their health as good (average sleep score 63%).
  • Average sleep score tended to decrease with age.
  • Only 38% of the respondents were classified as “good sleepers”.
  • 36% were classified as possibly having chronic insomnia.
  • 79% of those with insomnia reported having it for at least two years.
  • Over four times as many people with insomnia reported relationship difficulties, compared with good sleepers.
  • Over 45% of those with insomnia had difficulty staying awake during daylight hours compared with just over 10% of good sleepers.
  • Nearly 95% of people with insomnia reported low energy levels in their daily lives, compared with over 40% of good sleepers.
  • Over 75% of people with insomnia experienced poor concentration.

What Does the NHS Say?

Poor sleep can be physical or mental, and is definitely affected by our levels of exercise and quality of our nutritional intake.

Here are a few reasons that cause sleep issues, from the NHS :

  • Obesity
  • Pregnancy
  • Illness
  • A lack of muscle strength which can make you tire more easily
  • Side effects of medicines
  • Some medical treatments
  • Drinking too much alcohol  
  • Too much stimulants found in tea, coffee, colas and energy drinks
  • Excessive amounts of sugar
  • Daytime napping will affect your sleep pattern and readiness for bed and a good night’s sleep
  • Too much or too little exercise can affect how tired you feel.
  • Stress
  • Worries
  • Emotional shock (bereavement, redundancy or a relationship break-up)
  • Anxiety

What Lies is Your Brain Telling You?

Two of the techniques I use in coaching support people to reframe thoughts, beliefs, and perceptions, and to change behavioural patterns.  The techniques are NLP (neuro linguistic programming), and CBT (cognitive behavioural therapy).  These techniques are extremely powerful in making mind set shifts, but also in hunting out our perceived reality about a situation.  You may have heard the saying ‘you get what you focus on’? Well this is true in part because of how our brains work.  Our primitive brain will delete and distort information to protect us, even if we’re not asking it to, and thank you but that’s not always very helpful, brain.  So if you are stuck in a ‘can’t sleep, won’t sleep’ rut and it isn’t a physical health related issue that’s causing it, you can disrupt the pattern and get it under control through coaching.

Sleep Trivia
