糟糕的睡眠会影响你的心理健康
导读:
我们每个人每天都需要足够的睡眠来保持和恢复体力。睡眠不足所带来的负面影响有哪些?一项研究发现缺觉不仅会影响我们的身体健康而且还会给我们的心理健康造成危害。本次讨论不良睡眠对人的影响。
一、语篇泛读
How much sleep do you need Do you find that if you don't get enough shut-eye and wake up feeling dopey, you spend the rest of the day in a bad mood I certainly need my eight hours a night and that's important according to research, because bad sleep isn't good for our health.
We all need a good night's rest to recharge our batteries, but according to the Sleep Council in the UK, the average Briton gets six-and-a-half hours sleep a night, which for most people is not enough. It's tempting to cut back on the sleep we get, after all there are plenty of other more fun or useful things to be doing. Sometimes the pressure of work or a long commute means that our head hits the pillow much later than it should. But lots of studies have shown that cutting back on sleep, deliberately or otherwise, can have a serious impact on our bodies.
Studies have proved that sleep deprivation has a negative effect on our bodies but it can also have an effect on our mental health. A BBC programme called Trust Me, I'm a Doctor ran an experiment with the University of Oxford and was surprised to discover how quickly the mood of the people they were testing changed when their sleep was restricted to four hours a night for just three nights. Doctoral student, Sarah Reeve, who ran the experiment, said: "There were increases in anxiety, depression and stress, also increases in paranoia and feelings of mistrust about other people".
This and other research into the mental health of students, has found that the lack of sleep increases our negative emotions. I know that when I'm sleep deprived, it is harder to feel positive about things or even think straight! Daniel Freeman, professor of clinical psychology at Oxford University, agrees that insomnia is bad for our brain. He says: "We have more negative thoughts when we're sleep-deprived and we get stuck in them".
Bad sleep doesn't automatically mean you'll get mental health issues but other studies have shown that depriving people of enough sleep for only a few nights in a row can be enough to put healthy adults into a pre-diabetic state. So with all this evidence maybe we should concentrate on sleeping well. This means going to bed at a sensible time and creating the right environment in the bedroom to relax and sleep in. There's also the modern distraction of using smartphones and tablets at bedtime, tempting us to stay awake. The blue light emitted by electronic devices makes us feel less sleepy. And using them stimulates our brain when it should be winding down. What helps you get a good night's sleep

我们离半机械人时代又近了一步
导读:
多年来,科幻小说一直在不断地为我们描绘各种体能超强的半机械人类生活在未来的场景。随着生物科技的迅速发展,半机械人类的时代离我们又近了一步。最新的一项生物科技突破是否证明集成技术的发展前景无限光明?本集《外刊精读》带你走进生物科技。
一、语篇泛读
Vocabulary: biotechnology 词汇: 生物技术
I am a massive science fiction geek. Ever since I was young, I’ve been captivated by tales of interstellar adventure, aliens, robots, and cutting-edge technology. I always loved the concept of cyborgs. That’s a human-robot hybrid. They are ordinary humans who have been enhanced in some way by technology; more intelligence, faster speed or better resilience to disease and damage. Great ideas, but I never thought I’d see them in my lifetime.
Well, I stand corrected. Integrated biology and technology is already here and people have wasted no time utilising it to re-engineer their bodies. Take, for example, Neil Harbisson, who has an antenna protruding from his head that allows him to hear colour, or Moon Ribas, who has an implant that allows her to sense seismic activity. Now, neither are abilities that I particularly covet, but it's a start.
And it doesn’t end there. As technology increases so too will our ability to enhance ourselves through it. One of the latest developments is the graphene tattoo. Not an actual tattoo at all, but more like a patch, the graphene tattoo could revolutionise biomedical monitoring.
It looks much like a transparent plaster, but with a gold coloured circuit board contained within it. This circuit is the graphene. Graphene is a form of carbon, but it’s 200 times stronger than steel and conducts electricity better than gold, which is the component typically used in electronics.
The human body is basically an electrical machine. When in contact with the skin, the graphene in the plaster is able to read and conduct the electricity – allowing it to easily be used as a medical monitor for heart-rate and pulse, among other things. And even more, graphene tattoos can be used as bioelectronic controllers, as demonstrated by one engineer who attached them to his eyelids in order to direct which way a drone flew, just by looking with his eyes!
I know that biotechnology is a long way from allowing humans to be able to lift a car or run half-way around the world in a single day, like I wanted to be able to do when I was a child. But, it’s improving all the time and once the price of graphene falls, who knows what else we’ll be able to do I’ll see you in the future!
