Creature Sleeps

Almost every living creature sleeps. For humans, it is typically something we dislike doing when we are younger and, as we age, something we increasingly look forward to at the end of each day. On the one hand, it is something that we absolutely need to sustain our life and on the other, we tend to feel guilty if we spend more time in bed than we should. Sleep researcher Professor Stanley Limpton believes that 7 hours – the average amount of sleep most people get per night – is not enough. Limpton points out that the average person is now getting 2 hours less sleep than those who lived 100 years ago and contends that this lack of sleep is one of the main reasons so many people are often clumsy, unhappy, irritable and agitated. Other scientists share Limpton’s thinking. Many other researchers feel that we are not getting enough sleep and the negative impacts are being regularly felt around the world in the workplace and in the home. The first experiments in recorded scientific history on the effects of people not getting enough sleep took place in the late 1800s. According to records, three volunteers were deprived of sleep for a total of 90 hours. Later on, in 1920 more experiments in sleep deprivation were conducted by scientists where several people were deprived of sleep for a period of 60 hours. The results of many sleep deprivation experiments have been recorded and conducted by American ‘sleep scientist’ Nathaniel Kleitman. Often referred to as ‘the father of modern sleep research’, Kleitman’s work has formed the foundation for many areas of current sleep research.…
