Sleepy people the dangers of sleep deprivation Essays - Sleep, Nap

Sleepy people the dangers of sleep deprivation Do this test tonight when you go to bed. Put a plate on the floor next to your bed. Lie down with one hand hanging over the bed holding a spoon above the plate. When you fall asleep, the spoon will fall on the plate and should wake you up. If you dont wake up until the next day, it probably means you are sleep deprived. We live in a world of tired, sleep deprived people. This is the theory of behavioural biologist, Paul Martin. In his book Counting Sheep, he describes a society which is just too busy to sleep and which does not give sleeping the importance it deserves. We all know the importance of having a healthy diet and doing exercise, but we dont worry enough about sleeping the hours we need. Paul Martin says: We might live longer and happier lives if we took our beds as seriously as our running shoes. So much to do, so little time Modern society has invented reasons not to sleep. We are now a 24 / 7 society where shops and services must be available all hours. We spend longer a t work than we used to, and more time getting to work. Mobile phones and email allow us to stay in touch round the clock and late-night TV and the Internet tempt us way from our beds. When we need more time for work or pleasure, the easy solution is to sleep less. The average adult sleeps only 6.2 hours a night during the week, whereas research shows that most people need eight or even eight and a half hours sleep to feel at their best. Nowadays many people have got used to sleeping less than they need and they live in an almost permanent state of sleep debt, owing their bodies perhaps 2530 hours of sleep. Going against nature Until the invention of electric light in 1879 our daily cycle of sleep used to depend on the hours of daylight. People would get up with the sun and go to bed at nightfall. But nowadays our hours of sleep are mainly determined by our working hours (or our social life) and most people are woken up artificially by an alarm clock. During the day caffeine, the worlds most popular drug, helps to keep us awake. 75% of the worlds population habitually consumes caffeine which, up to a point, masks the symptoms of sleep deprivation. Sleepy people What does a chronic lack of sleep do to us? As well as making us irritable and unhappy as people it also reduces our motivation and ability to work. This has serious implications for society in general. Doctors, for example, are often chronically sleep deprived, especially when they are on night call and may get less than three hours sleep. Lack of sleep can seriously impair their mood, judgment, and ability to take decisions. Our politicians are often jet-lagged after crossing time zones. World summit meetings called to deal with a crisis often result in decisions being taken after marathon sessions when everyone is severely sleep deprived. human error caused by tiredness contributed to the worst nuclear accident in history at Chernobyl in 1986. Tired engineers, in the early hours of the morning, made a series of mistakes with catastrophic results. On our roads and motorways lack of sleep kills thousands of people every year. Tests show that a tired driver can be just as dangerous a s a drunk driver. However, driving when drunk is against the law but driving when exhausted isnt. As Paul Martin says, it is very ironic that we admire people who function on very little sleep instead of criticizing them for being irresponsible. Our world would be a much safer, happier place if everyone, whatever their job, slept eight hours a night. SLEEP TIPS 1 Give sleep a high priority in your life. 2 Listen to your body.
