Understand Your Sleep

Sleep is an important part of our life, and one of the key pillars for good health. 

Explore the science behind sleep.

Why we sleep

Lots of important biological processes essential for good health are going on inside our bodies while we are resting, including:
  • Giving our body time to recover and repair itself (allows cells to repair and regrow)
  • Improving how our memory functions
  • Helping support a healthy brain and improving our mood

Sleep cycles

Not all sleep is the same – as we sleep, our brains go through a series of ‘sleep cycles’. 
Which are made up of two different types of sleep:

Rapid-eye movement (REM) sleep

Rapid-eye movement (REM) sleep

  • this type of sleep is vital for storing and sorting our memories from the day; the brain is very active, and this is when dreams are likely to occur

Sleep and ageing

As we age, our bodies may make less and less melatonin (the hormone that facilitates sleep onset and good sleep quality) which can eventually make us feel that our sleep is restless, light or of poor quality. Ageing can affect people’s sleep in different ways, including:
  • The body’s circadian rhythms can desynchronise, so that our bodily rhythms, such as melatonin release, are not aligned with the day/night cycle
  • We are more likely to wake up during the night
  • We are more likely to feel that our sleep is restless, light or of poor quality, and wake up feeling unrefreshed in the morning
  • We are more likely to take daytime naps
  • It can take longer to get over upsets to our normal sleep patterns

How do I know if I have a Sleep Problem?

Many people have trouble falling asleep or staying asleep. Others feel that their sleep is restless, light or of poor quality. They wake up feeling unrefreshed. Everyone’s idea of a ‘good night’s sleep’ varies, so the amount of sleep considered ‘a problem’ for one person may not be an issue for someone else. However, sleep problems can start to arise when:

  • You’re concerned about the lack of sleep, or your sleep quality
  • It starts making you feel tired or sleepy during the daytime
  • It’s affecting how well you function at work or when doing everyday activities.

If you are unsure about how well you sleep, try keeping a sleep diary to help keep track of your sleep patterns and how you are feeling.

If you’re concerned about the amount or the quality of your sleep, it’s important to seek advice from your doctor or your pharmacist.

What can I do to try and prevent Sleep Problems?

Poor sleep hygiene (sleep habits) is a common cause of sleep problems.

One of the most important steps in improving your sleep hygiene is to establish a regular sleep routine. This can involve maintaining regular pre-bed activities, keeping your bedroom surroundings relatively constant, and waking up at the same time each day. However, you should avoid going to bed if you aren’t tired, even if it means going to bed at irregular times.

Here are a few steps you could try:

  • Avoid caffeinated drinks before going to bed
  • Avoid napping during the day
  • Limit your alcohol and cigarette use before bedtime
