According to the Daily Mail, a University of Leeds study shows that getting less than 5 hours of sleep can lead to a bad temper as well as memory loss.
The research, which was carried out in conjunction with bed maker Silentnight analysed the effects of sleep on memory and daily functions.
People who took part were aged between 18 and 80 and they were tasked with measuring their sleep against five ‘everyday’ memories, consisting of: having to check whether they’ve done something; forgetting to tell somebody something important; where things are normally kept; doing something they intended to do such as posting a letter and finding it difficult to concentrate.
The most apparent memory failure was having to check whether they had done something (50 per cent) and this was followed by forgetting to do something they intended to do (44 per cent).
Those who slept for less than five hours were 25 per cent more forgetful than those who slept longer.
And half of the poor sleeper ‘regularly’ struggled to concentrate.
