Adults need at least 7 but ideally 8 hours of sleep

Recent research indicates that healthy adults needs a minimum of seven hours sleep per day and, ideally, eight hours.  The average teenager needs about 10 hours.

When sleep is restricted to less than seven hours per night it results in reduced working memory capacity, impaired vigilance, lowered attention span and poor comprehension.

Your memory may be unreliable due to poor sleeping habits. You need both deep sleep and REM (dreaming) sleep to be able to learn and remember effectively. Using high energy drinks to keep yourself awake through the night studying for exams is less effective than having a good night’s sleep.

While you are sleeping – if you are under 30 years of age (approx) – you will be consolidating new knowledge in periods of deep sleep. Unfortunately after about 30 the frequency of deep sleep declines so it is harder to consolidate new facts.

It is very difficult for anyone to learn a new skill or maintain a reliable memory of prospective appointments without adequate sleep. If your memory is unreliable due to lack of sleep, your overall levels of stress increases, which further reduces your ability to remember anything. Be kind to your prefrontal cortex – take a nap. It will help.

People who experience continual poor sleeping patterns may complain of things like -

  • forgetting names, appointment times and dates,
  • forgetting where you have left the car or the mobile phone
  • trouble concentrating, especially in meetings
  • thinking more slowly
  • poor focus – becoming easily distracted, especially when driving
  • difficulty learning new skills

If you can’t solve your lack of sleep problem it is still possible to reinvigorate your tired brain with memory strengthening techniques using Associative Cognitive Recall (ACR). ACR is a model of how the memory works developed from current research.
