Did you know...

blue light emitted from devices such as phones and TVs supresses the natural production of melatonin? Melatonin is the hormone that you need to feel sleepy.

How much sleep do I need?

There are many factors that will contribute to the amount of sleep each individual needs but it mainly depends on your age.

  • Babies typically sleep for about 17 hours
  • Children need approximately 9 to 10 hours sleep
  • Adults need about 8 hours sleep
  • Older people typically still need 8 hours of sleep however they will often only have one period of deep sleep during the night

These hours are only recommendations and are based on the average person, some people will need more and some will need less.

Stages of Sleep

Sleeping is a complex process with 4 different stages that make up a sleep cycle.

When we first fall asleep we enter non-rapid eye movement sleep (NREM). This is divided into three stages, with each becoming progressively deeper.

Stage 1 and 2 are light phases of sleep, from which we can be easily roused.

Stage 3 becomes deeper, and if woken up, we can feel disorientated.

Stage 4  is known as rapid eye movement sleep (REM), the stage at which we dream.

Each sleep cycle lasts around one and a half hours, and in order to feel fully rested and refreshed when we wake up, we must experience all four stages. A full night’s sleep will include of five or six cycles, while a disturbed, restless night consists of fewer.
