The effects of fatigue can be devastating and the worse thing is that you may be suffering and not even understand the ways that fatigue is affecting you. Fatigue and feeling sleepy are the principal causes of both workplace and road accidents.
If you are not getting enough sleep it is very difficult to function during the day but research is now telling us that it will also affect our ability to remember things that we have learned as well.
In this article at http://theconversation.edu.au/by Russell Conduit a Lecturer in Psychological Sciences at Monash University, he talks about how a lack of sleep can affect your memory:
But researchers, myself included, are now showing that sleep not only plays a vital role in supporting normal daytime functioning: it’s important for committing to memory the lessons we have learnt during the day.
In other words: bad sleep equals bad memory.
Procedural skill learning (whether that be studying a language, chopping wood or learning to drive a car) in particular has been shown to be sleep-dependent.
Significant improvements in such tasks are only seen if one sleeps between learning the procedure and retesting.
Beyond basic procedural tasks, new research has shown that our capacity to remember emotional events and our ability to find creative solutions to mathematical puzzles (i.e. creative insight) are also sleep-dependent.
This does seem to make sense as many dreams are highly emotional and many artistic and scientific creations are inspired by dreams (e.g. The tune for Yesterday came to Paul McCartney in a dream; Otto Loewi’s Nobel Prize winning work on chemical neurotransmission was inspired by a dream).
Recently, researchers at the University of California, Berkeley, have found bursts of brain waves known as “sleep spindles” may be networking between key regions of the brain to clear a path for learning.
They provided strong evidence that sleep may facilitate brain plasticity, the mechanism whereby lasting structural and/or functional neuronal changes occur in the brain in response to ongoing experience.
In other words, our brains physically change when we sleep, being shaped by our experiences of the previous day.
The research I’m involved in at Monash University has found new evidence to suggest this physical change in the brain during sleep is vitally important for a healthy mind and normal daytime functioning.
So much so that even small disruptions to sleep can cause observable deficits in cognitive function, learning and memory.
Currently, we are investigating learning and memory processes of people with sleep disorders. We’ve also shown that as little as one disrupted night’s sleep can be enough to affect performance the following day in people without sleep disorders.

So are you getting enough sleep or are you building up a sleep debt that would rival most countries national debt.
A lack of sleep affects all of us and the longer that it goes on for the more difficult you will have functioning and completing, or even remembering your daily tasks.
Sleep deprivation puts you and colleagues at risk in a workplace and is the leading cause of workplace accidents.
